It is important to examine this relationship because athletic trainers frequently use ankle taping and/or bracing and have specific reasons as to why they choose one over the other. Athletic trainers must choose between the two types of ankle prophylactics every day when preventing and treating ankle injuries. There was minimal research that supported the preference health care professionals utilize for ankle prophylactics. However, research has indicated similarities and differences between the two types. Both taping and bracing use result in little to no decrease in functional performance. According to research by Nelson et al,1 bracing is a better option to use when one focuses on only injury prevention. Bracing tends to keep the foot in a more stabilized, closed packed position longer than taping does. Meana et al2 reported that ankle tapings have a decrease in 50 percent of the ankle range of motion after a 30 minute exercise session, while bracing keeps the restricted range of motion longer. In addition, bracing is also a better option when looking from a cost standpoint. Buying 2 individual braces for each ankle is far cheaper than buying several boxes of tape. Since most of the research points to using bracing over taping as a better option, it is important to see if athletic trainers are following research or using tape more often. There are various other reasons that one would choose either device over the other, which should be determined as well. Ankle injuries are highly prevalent among athletes. Abián-Vicén et al3 states acute lateral ankle injuries are the most common athletic-related injuries with an incidence rate of 38% to 50% of all athletic injuries reported. According to Nelson et al,1 ankle injuries occur most in football and men’s and women’s basketball. Not only is there a high incidence of initial ankle injuries, but there is also a high rate (as high as 80%) of re-injury.4 Because of the prevalence of ankle injuries in the active population, preventative methods for ankle injuries have been implemented for the athletic population by athletic trainers. Ankle taping and bracing are used for prophylactic and protective purposes in athletic activity on a daily basis. Hubbard and Kaminski5 and Delahunt et al6 describe how improving propioception and neuromuscular control is needed to improve mechanical ankle instability. 3 The incorporation of prophylactics is also commonly used with athletes who have sustained previous ankle injuries or who are recovering from initial ankle injuries. Delahunt et al6 state prophylactics have shown to decrease the incidence of ankle injuries, though the exact reasoning is not known. Due to the high frequency use of ankle prophylactics in sports, how these affect athletic performance have been questioned. Conflicting information has been found on whether or not taping and bracing affect sports performance. Abian-Vicen et al3 found ankle taping has no effect on jumping or balancing. Macpherson et al7 found no functional differences between football players with and without ankle bracing during functional activity. However, Mackean et al8 found decreases in vertical jump and jump shot with female basketball players wearing taping or bracing. This study will attempt to answer the following questions. Will preference of prophylactic device be dependent upon Athletic Trainers employment setting? Will Athletic Trainers employment setting be dependent upon preference of taping technique to prevent injury? Will Athletic Trainers employment setting be dependent upon preference of taping technique after injury? 4 METHODS The primary purpose of this study was to examine Certified Athletic Trainers use of ankle prophylactics in the prevention and treatment of injury. A comparison of these findings to current recommendations in the literature was drawn. This section will include the following subsections: Research Design, Subjects, Instruments, Procedures, Hypotheses, and Data Analysis. Research Design A descriptive design was used in this study. The dependent variables in this study were taping or bracing and preventing or post-injury prophylactic use. The independent variable was employment setting of Certified Athletic Trainers: high school, high school/clinic, or college. The strength of this study was that content validity was established for the survey after review by the panel of experts. The limitation of this study was that only Athletic Trainers who are members of the National Athletic Trainers’ Association (NATA) were surveyed because not all Certified Athletic Trainers are members of the NATA. 5 Subjects The subjects used for this study were 1000 male and female National Athletic Trainers’ Association (NATA) members, with 500 from the college work setting and 500 from the high school or high school/clinic setting. Participants were randomly selected from the NATA membership roles. Each participant who returned a survey (N = 196) was implying informed consent by returning the survey to the researcher via SurveyMonkey.com. Preliminary Research Prior to distribution of the survey, a review of the survey was conducted using a panel of three experts (Appendix C1). This panel reviewed the survey and provided suggestions for improvements. The panel included three certified athletic trainers from California University of Pennsylvania. 6 Instruments The Certified Athletic Trainers Use of Ankle Prophylactic Devices Survey (Appendix C2) was used in this study. This survey was developed by the researcher for the purpose of determining the use of ankle prophylactic devices when preventing and treating injury. Basic demographic information was obtained, including work setting, age, and years of experience. The survey also contained questions regarding the type of ankle taping or bracing used by athletic trainers to prevent and treat ankle injuries. In addition, the survey allowed for athletic trainers to provide their reasons for choosing one type of prophylactic device over the other. The survey had 13 questions and took approximately 5 to 10 minutes to complete. Procedures The California University of Pennsylvania’s Institutional Review Board was sent the Protection of Human Subjects form (Appendix C3) for approval before the study was conducted. A survey (Appendix C2) was developed by the researcher and was deemed valid after review by a panel of 7 three experts. The researcher utilized SurveyMonkey.com to create a direct link to the electronic survey. The researcher completed the Research Survey Request Form on the NATA website and it was distributed by the NATA electronically randomizing members who were in the high school, high school/clinic, and collegiate work setting. A cover letter (Appendix C4) was sent with the survey link explaining the purpose of the study to the Certified Athletic Trainers. A link on the cover letter provided the athletic trainers direct access to begin the survey. The NATA sent the survey to a maximum of 1000 members by email with the cover letter and link to the survey. A follow-up email was also sent by the NATA as a reminder one week after the initial email. The researcher was not given any demographic information or access to the email addresses of the athletic trainers, therefore, the surveys remained anonymous and the identities of the subjects was protected. 8 Hypotheses The following hypotheses were based on previous research and the researcher’s intuition based on a review of the literature. 1. Athletic Trainers preference of prophylactic device will be dependent upon employment setting. 2. Athletic Trainers preference of taping technique to prevent injury will be dependent upon employment setting. 3. Athletic Trainers preference of taping technique after injury will be dependent upon employment setting. Data Analysis All data was analyzed by SPSS version 18.0 for windows at an alpha level of 0.05. 1: A 3 (Taping Technique – tape, brace, or both at the same time) X 3 (Certified athletic trainer employment setting – high school, high school/clinic, and college) Chi square test of independence was used to determine if preference of prophylactic device was dependent upon employment setting. 9 2: A 8 (Taping technique to prevent injury – closed basket weave, open basket weave, spatting, peroneal, fibular, spartan slipper(boot,) subtalar sling, and other) X 3 (Certified athletic trainer employment setting – high school, high school/clinic, and college) Chi square test of independence was used to determine if preference of taping technique to prevent injury was dependent upon employment setting. 3: A 8 (Taping technique after injury – closed basket weave, open basket weave, spatting, peroneal, fibular, spartan slipper(boot,) subtalar sling, and other) X 3 (Certified athletic trainer employment setting – high school, high school/clinic, and college) Chi square test of independence was used to determine if preference of taping technique after injury was dependent upon employment setting. 10 Results The purpose of this study was to examine athletic trainers use of prophylactic devices in the prevention and treatment of ankle injuries. The data was obtained using a survey created by the researcher. This section contains the following subsections: Demographic Data, Hypothesis Testing, and Additional Findings. Demographic Data A sample of 1000 certified athletic trainers, who are members of the National Athletic Trainers’ Association, were randomly selected to participate in the survey. Of the 1000 asked to participate, 196 responded and completed the survey. According to Patten,9 based on the population of athletic trainers who indicated they work in the collegiate or high school setting, a sample size of 375 was needed. This indicates a return rate of 52.4%. Table 1 represents general characteristics associated with the athletic trainers and Table 2 represents the gender classifications. Table 1.

Hypothesis 1: A 3 (Preference of prophylactic Device – tape, brace, or both at the same time) X 3 (Certified athletic trainer employment setting – high school, high school/clinic, and college) Chi square test of independence was used to determine if preference of prophylactic device was dependent upon employment setting. A significant interaction was found (χ2 = 15.13, P < 0.01). Conclusion: Athletic trainers in the collegiate setting were more likely to use both bracing and taping at the same time after an acute ankle injury than athletic trainers in the high school and high school/clinic settings (Table 13).

The choice of spatting was not included in the test because no subjects chose that option. A significant interaction was found (χ2 = 29.272, P < 0.01). Conclusion: Athletic trainers in the collegiate setting were more likely to use the closed basket weave taping technique for prevention of injury than high school and high school/clinic athletic trainers (Table 14).

For the first additional finding, a Chi Square Goodness of Fit tests were calculated comparing the frequency (yes or no) for reasons athletic trainers chose for their preference of prophylactic device. The following reasons were selected by athletic trainers as “yes” for significant results: Subjects knowledge of the literature (χ2 = 18.789, P < 0.01); Athlete preference (χ2 = 13.392, P < 0.01); Personal opinion/experience (χ2 = 156.241, P < 0.01); provides more stability than other choices (χ2 = 52.082, P < 0.01); and prevents injury better than the other choices (χ2 = 35.377, P < 0.01). The following reason was selected by athletic trainers as no for significant results: preference is easier to apply or does not take as much time to apply as other choices (χ2 = 30.026, P < 0.01). No significant results were found for “Budgetary limits” and “It is how the subject was taught and/or how all of his or her peer AT’s choose”. Refer to Table 12 for statistical results. The second test performed was a Chi-Square Test of Independence comparing employment setting with preference of brace type after injury. A significant interaction was 21 found (χ2 = 12.58, P = 0.05). Athletic trainers in the collegiate setting chose the lace-up type while the other employment settings did not (Table 16).

The following section will discuss these findings and is divided in the following subsections: Discussion of Results, Conclusions, and Recommendations. Discussion of Results This study focused on the athletic trainers’ preference of prophylactic devices before and after an ankle injury. Ankle injuries are very common orthopedic injuries that may lead to chronic ankle instability. These injuries may cause athletic trainers to recommend and use prophylactic devices in order to prevent or treat injuries. The researcher examined different demographic information such as work setting, gender, and years of experience to determine if it affected their preference of prophylactic device. The researcher’s first hypothesis focused on the belief that preference of prophylactic device would be dependent upon employment setting. There was no previous research performed examining athletic trainers preference 23 of prophylactic devices. Based on the researchers own experience and intuition, one might believe athletic trainers from the collegiate setting would be more likely to use tape or bracing than athletic trainers in a high school or high school/clinic setting. It was determined athletic trainers who work in the collegiate setting were more likely to use prophylactic devices after an acute ankle injury than those who work in a high school or high school/clinic setting. These results are similar to the study completed by Mickel et al10 which stated the use of bracing as cost effective, as well as the best method to prevent injury versus tape. The researchers recommended bracing over taping, however the results of this study indicated that athletic trainers chose to use both bracing and taping. One of the reasons for this may be attributed to comfort for the athlete. Reuter et al11 surveyed the participants of their study to describe which prophylactic device is more stable and more comfortable. The researchers found taping to be more stable but less comfortable while bracing was found to be more comfortable but less stable. The athletic trainers’ preference of using both tape and bracing could be attributed to both aspects: comfort and stability. 24 The second hypothesis examined in this study stated athletic trainers’ preference of ankle taping technique to prevent injury will be dependent upon employment setting. The researcher hypothesized athletic trainers in the collegiate setting would be more likely to use a standard ankle taping than the other employment settings. There is no previous research to indicate if taping technique preference changes with employment setting; however, from the researcher’s prior experience, there seems to be a difference because of a variety of reasons. The results coincide with the hypothesis indicating that collegiate athletic trainers use a closed basket weave. There have been previous studies completed that indicate certain taping techniques are more efficient and stable than others. Abian-Vicen et al12 found taping with elastic tape (elastikon, Powerflex) and inelastic tape provided the same amount of restricted range of motion and stability, but elastic was found to be more comfortable. Abian-Vicen et al12 recommended the use of elastic tape because of these reasons. The researchers in this study found a significant majority of athletic trainers chose an all inelastic tape, which is a direct contradiction to the research. One of the reasons may be related to education, 25 since standard closed basket weave ankle procedures with inelastic tape is taught first to athletic training students as well as emphasis placed on the effectiveness of this taping procedure. The third and final hypothesis stated preference of taping technique after injury would be dependent upon employment setting. Again, there has been no previous research to support this specific hypothesis. However, the researcher hypothesized after injury the collegiate employment setting would choose an ankle taping that has different materials generally thought of as stronger taping. However, no significant results were shown to support this hypothesis. With a lack of significance, the results demonstrated athletic trainers from different employment settings do not prefer a certain taping technique after an ankle injury. In addition to examining the hypotheses, the researcher discovered additional findings by using supplementary demographic and preference questions. The first additional finding examined athletic trainers reasons for choosing their preference of ankle prophylactic. There were a number of significant findings when a majority of athletic trainers chose similar reasons. The significant 26 reasons were: subject’s knowledge of the literature, athlete preference, personal opinion/experience, preference provides more stability than other choices, preference prevents injury or re-injury better than the other choices, and lastly the preference is easier to apply or does not take as much time to apply. The two reasons that did not yield significant results were: budgetary limits and chosen preference based on skills learned or peer choice. The second additional finding used athletic trainers’ employment setting and their preference of brace type after an ankle injury. There were significant results indicating that athletic trainers in the collegiate setting chose a lace-up brace while others in the high school and high school/clinic settings did not. This finding coincides with research completed by Rezents et al,13 which found that lace-up ankle braces were found to be more supportive and preferred by athletes. 27 Conclusions The results of this study both support and oppose the results of previous studies. The overall results indicated that athletic trainers chose both bracing and taping after an acute injury, which did not defend Mickel et al10 who found that bracing is more stable and cost effective. Based on the results of this study, the researcher can concluded athletic trainers have similar preferences of prophylactic devices in the collegiate setting. This could be a credit to similarity of the college level, the maturity level of athletes, the increased risk of injury, or a number of reasons. Recommendations The results of this study demonstrated athletic trainers chose standard closed basket weave ankle tapings and the use of a brace after an ankle injury. In order to aid in determining if employment setting changes the way athletic trainers chose a prophylactic device, future research is suggested. For example, in the collegiate setting, athletic trainers could specify their NCAA 28 division level of I, II, or III and in the high school setting, athletic trainers could choose their classification of A, AA, AAA, etc. In addition, further research should obtain more information about the reasons athletic trainers chose their preference. Another follow-up study might focus more on athlete preferences of prophylactic devices by gender, sport, and athletic level, then compare to the athletic trainer preferences. 29 REFERENCES 1.

Because of the high incidence rate, health care providers, including athletic trainers, physicians, and orthopedic surgeons, have turned to the use of prophylactic devices to rehabilitate and prevent injury and re-injury. The prophylactic devices most commonly used are ankle taping and bracing. Multiple types of ankle tapings and braces can be used by an athletic trainer, but there has been little research on which type is preferred or most popular. The purpose of this Review of Literature is to enlighten the reader on previous work examining the use of tape by athletic trainers and their preferences in taping and bracing types when preventing or rehabilitating an ankle injury. This will be accomplished in the following sections: Importance and Background of Ankle Prophylactics, Clinical Practice of Taping and Bracing, and Ankle Taping and Bracing. Each section will be further divided into subsections as well. Under the Importance and Background of Ankle Prophylactics, the Mechanism and Frequency of Ankle Injuries, Chronic Ankle Instability, and Prevention of Ankle Injuries will be discussed; Clinical Practice of 34 Taping and Bracing will include Types of Ankle Taping and Bracing as well as Clinical Education; and lastly, Ankle Taping and Bracing will discuss the Effects on Functional Performance and Reliability of Injury Prevention. A summary of the review of literature is also provided. Importance and Background of Ankle Prophylactics Mechanism and Frequency of Ankle Injuries Acute ankle injuries are the most commonly occurring injury during athletic-related activities. These injuries make up approximately 38% - 50% of all injuries reported.1 According to Robbins and Waked,2 the most common type of ankle injury is a lateral ligamentous sprain, accounting for about 85% of injuries. The ankle is the least stable in the open packed position of plantar-flexion and inversion, which is how most ankle injuries occur.2 Mechanisms of ankle sprains also differ by sport. In football, the most common mechanism is contact with another player, while in basketball it is landing from a rebound or jump.3 The inversion and plantarflexion mechanism causes the anterolateral structures to be stretched which makes the ankle far less stable and increases the risk of re-injury. Repeated stretching of these structures in the ankle can 35 lead to instability and the need for the use of prophylactic devices. According to Robbins and Waked,2 ankle sprains occur because footwear causes a decrease in one’s foot position awareness compared to when barefoot as well as changes in the foot position resulting in an increase in chance of injury. Wearing braces or taping helps to correct the foot back to its normal position which helps decrease the chance of injury. However, the researchers concluded that taping and bracing also decrease the range of motion ankles have, which may increase the chances of re-injury. Their final conclusion is that the active population should find correct footwear that does not alter foot kinematics and position awareness so ankle injuries can be prevented without limiting range of motion. Hubbard and Hertel4 also concluded that both hypermobility and hypomobility at the talocrural, subtalar, and inferior tibiofibular joints can significantly contribute to chance of injury/re-injury. The frequency of ankle injuries also varies by sport. According to a study completed by Nelson et al3 the researchers investigated the prevalence of ankle injuries by sex, type of exposure, and sport. One hundred high schools across the country submitted their injury data from the 2005-2006 school year. Using the injury surveillance 36 system, the researchers collected data about ankle injury type, athletes’ sex, and sport. The results indicated that ankle injuries occurred at a much higher rate during competition than in practice. In addition, the sports with the most incidences were, from highest to lowest, boys’ basketball, then girls’ basketball, and finally football. The researchers concluded that sports with jumping in close proximity to others and with quick changes of direction were the most often associated with ankle injuries.3 Nelson et al3 also noticed a significantly higher number of injury occurrences during competition than in practice in all sports except for women’s volleyball. Chronic Ankle Instability Along with the high incidence of ankle injuries in physical activity, a high occurrence of re-injury to the ankle is also an area of great concern to athletic trainers. Re-injury rates have been recorded as high as 80% in the active population.5 Because of this high rate, individuals who have suffered multiple consecutive ankle injuries in addition to continuous symptoms such as instability in the ankle are diagnosed with chronic ankle instability.5,6 37 The presence of chronic ankle instability is thought to be due to mechanical ankle instability (MAI) and functional ankle instability (FAI).4,5 MAI refers to the occurrence of excessive ankle range of motion due to laxity in the ligamentous structures, namely the anterior talofibular and calcaneofibular ligaments.5,7 It also includes arthrokinematic restrictions, degenerative changes, and synovial changes.5,7 MAI instability affects all the joints associated with the ankle including the subtalar, talocrural, and inferior tibiofibular joints.7 FAI components include decreased propioception, neuromuscular control, strength, and postural control.5,7 All these components are implemented into ankle rehabilitation programs to help decrease re-injury rates. Studies conflict with whether or not FAI and MAI occur simultaneously with an ankle injury, however it is generally accepted that the two types of instability are apparent with most cases of CAI.5 Chronic ankle instability has been found to not only solely affect kinematics of the ankle, but also the rest of the lower extremity kinetic chain.8 Time to stabilization upon landing after jumping has been found to be increased with chronic ankle instability with knee and hip flexion landing angles to be decreased.8 Gribble and Robinson8 38 completed a study in order to examine the contributions of lower extremity kinematics during an assessment of dynamic stability in people with chronic ankle instability. The subjects were separated into groups (those with CAI and those without), but all completed three drop landing tests while their ankle plantarflexion, knee flexion, and hip flexion were measured at the point of impact; ground reaction force data was also collected. The results indicated that the subjects with CAI had decreased dynamic stability in addition to a decreased knee flexion angle. The researchers concluded that decreased amount of knee flexion and dynamic stability could cause an increase in re-injury rates.8 Further research is also suggested to determine if prophylactic devices and various ankle rehabilitation programs could enhance the kinematic pattern of the lower extremity.8 In a study completed by Delahunt et al,5 participants were all CAI sufferers. The researchers wanted to determine which type of taping (lateral subtalar sling or fibular repositioning) could enhance dynamic postural stability in patients with chronic ankle instability. The participants completed the Star Excursion Balance test under three conditions: no tape, lateral subtalar sling taping, and fibular repositioning taping. The researchers concluded 39 that neither taping condition increased nor decreased the stability of the ankle. In addition, the subjects reported an increase in feelings of stability and reassurance when wearing the lateral subtalar sling taping over the fibular repositioning taping.5 The use of prophylactics has been shown to decrease the incidence rate of ankle injuries, although the exact reasoning is not known.5 Possible factors that ankle taping and bracing could help improve for MAI included joint arthrokinematic stabilization and chronic laxity and for FAI taping and bracing could aid in providing increases in proprioception and neuromuscular control.5 There have been numerous studies completed investigating these possible reasons, although research has not been consistent. Prevention of Ankle Injuries As previously stated, ankles are commonly injured. Because of this, the prevention of ankle injuries is extremely important to be able to keep athletes on the field. Most health care providers agree that establishing excellent neuromuscular control, proprioception, and strengthening are needed to increase dynamic stability and prevent re-injury.2 Vaes et al9 completed a study that followed volleyball teams throughout a whole season. They 40 were separated into two groups: control and testing. The testing group was given a balance board training program to complete and the control did not, and injury reports were then recorded. The results showed a significant decrease in the amount of ankle injuries in the testing group as well as a significant reduction in ankle sprain risk, but for only those with a history of injury. The researchers concluded that the use of this balance board program is effective in preventing ankle sprains and re-injury.9 Similarly, following an ankle injury, athletes need to re-establish the same characteristics. After injury, there are certain neurological deficits that need to be addressed. However, until this can be established, the use of ankle prophylactics may be needed for added support. According to Hubbard and Kaminski,10 ankle injuries cause a decrease in kinesthesia and proprioception. In this study, subjects with decreased kinesthesia caused by an ankle injury were tested under three conditions to determine if kinesthesia could be increased using taping or bracing. The participants were tested on a kinesthesia measurement system while wearing no prophylactic devices, taping, and two types of braces. The results indicated that the kinesthesia measurements were significantly better in the unbraced condition than in the two braced conditions, but 41 not the taping condition. The researchers concluded that bracing caused a decrease in kinesthesia awareness in the lower extremity, but stated that much more research needs to be done to determine the exact affect taping and bracing has on kinesthesia.10 Vaes et al9 investigated the effectiveness of external support on stabilization. They tested strapping, taping, and nine different braces. Once applied to the ankle, the talar tilt was measured in comparison to no support to find out the differences. The results indicated that taping and two of the nine braces significantly decreased the talar tilt levels. The researchers concluded that there should be three levels of effectiveness when referring to lower extremity external support and the effectiveness of this support should be determined before using it to treat or prevent ankle injuries.9 Refshauge et al11 determined whether or not proprioception is affected in people who have frequent ankle sprains. In addition, the researchers wanted to know if wearing ankle braces would help to increase the proprioception back to normal. Subjects (separated into recurrent sprains and no sprains) were tested with both tape and no tape on their proprioceptive abilities. The 42 results concluded that there were no significant differences between the two groups.11 Clinical Practices of Taping and Bracing Types of Ankle Taping and Bracing Several different kinds of ankle tapings and bracings are commonly used by athletic trainers. However, there has been minimal research on which type of taping or bracing is most reliable or most preferred. Rezents12 compared two types of ankle braces to determine which is better for athletic performance. The ankle braces used were Active Ankle and ASO lace-ups. The researcher measured all ranges of motion with and without the braces. The results indicated that the ASO brace had a greater decrease in ROM than the Active Ankle. In addition, when the athletes were surveyed, 93% stated they preferred the ASO brace because it felt more secure. Pope et al13 compared four types of ankle tapings. The taping techniques used were: taping with no figure eight, taping with figure eights, taping with no heel locks, taping with heel locks. They were applied to a model of the human ankle joint and then subjected to functional tests on a mechanical testing machine. The tests included 43 determining how far the ankle ROM could go before subjecting it to injury, torque to failure, and deflection. It was previously determined that eight degrees of angular deflection causes pain and that torques of 420 nanometers could be applied before injury occurs. The researchers determined that the ankle taping that included figure eights was the best. It was the only method that had the strength to withstand the most exterior forces than the other tapings and it was recommended over the others.13 In a similar study Abián-Vicén et al14 compared two types of ankle tapings. The purpose was to determine the level of fatigue for two types of tape after a 30 minute exercise session. The participants were tested with no tape, an elastic tape, and an inelastic tape. Measurements of ankle passive range of motion (PROM) were taken before and after exercise. The subjects were also asked about their level of comfort and restriction provided by the tape. The researchers found that after the exercise session there was less restriction in ankle plantarflexion and inversion for both types of tape, but that the subjects perceived the elastic tape as more comfortable and less restrictive.14 The researchers recommended using elastic tape over inelastic tape because range of motion was 44 restricted the same for both types, but elastic was preferred by athletes.14 Clinical Education To become a Certified Athletic Trainer, one must first enroll into an Accredited Athletic Training Education Program. In this program, students complete competencies and proficiencies in order to obtain the skills needed to graduate and become certified. According to the National Athletic Trainers’ Association, athletic training educational competencies are “the minimum requirements for a student’s entry level education.”15(p.2) The Commission on Accreditation of Athletic Training Education separated the competencies into twelve content areas and are the foundation of a student’s education.16 One of these content areas is Risk Management and Injury Prevention. Under this content area, students become proficient in taping and proper administrations of bracing for prevention and treatment of injuries. The Commission on Accreditation of Athletic Training Education (CAATE) along with the National Athletic Trainers Association developed the standards and educational competencies that all Certifed Athletic Trainers must learn.15,16 According to CAATE, students must complete a 45 competency pertaining to fitting a brace properly. Students must “appropriately select and fit appropriate standard protective equipment on the patient for safe participation in sport and/or physical activity to prevent/minimize the risk of injury to head, torso, spine, and extremities.”16(p.5) A certified athletic trainer must know how to use a variety of different braces for every joint in the body as well as the advantages and disadvantages of using them to be able to implement using prophylactic braces on athletes.16 There are taping competencies created by CAATE for athletic training students as well. Certified athletic trainers will be able to “explain, fabricate, and apply appropriate preventative taping and wrapping procedures…Procedures and devices should be consistent with sound anatomical and biomechanical principles.”16(p.5) All of these competencies are created to not only make sure that all athletic training students receive the same education, but they also serve to set a foundation for students’ education. 46 Ankle Taping and Bracing Effects on Functional Performance High rates of ankle injury have caused many athletes and athletic trainers to use protective equipment in order to prevent an initial injury or a re-injury. The most common methods for the ankle are a standard ankle tape or ankle brace. There have been multiple studies conducted on the functional performance of athletes who wear these protective measures. The factors most often compared are speed, agility, vertical jump, and balance performance. Recently, there have been conflicting results between studies on functional activities being affected by taping or bracing. A study completed by Abián-Vicén et al1 tested the effects of ankle taping on balance and jump tests. All subjects completed three tests with both tape and without tape. The results indicated no significant differences between the two testing groups. The researchers concluded that preventative taping measures do not affect the balance and jumping abilities of young, healthy athletes.1 There have also been studies7,8 that have been completed on the use of prophylactic taping and bracing on certain sports. These studies were conducted in basketball 47 and football. Macpherson et al7 compared the effects of softshell and semirigid prophylactic ankle stabilizers on male football players’ functional performance in speed, agility, and vertical jump. They concluded that neither of the ankle stabilizers caused a difference in speed, agility, or vertical jump.7 In a similar study, MacKean et al17 compared bracing and taping on functional performance of female basketball players. The athletes were evaluated in basketball-related activities (sprint, jump shot, and vertical jump) in five different scenarios: no tape, preventative taping, and three different types of bracing. Overall, the results indicated that taping and bracing did slightly affect the subjects’ abilities in basketball-related drills. Vertical jump and jump shot were decreased when the athletes wore tape and braces. This led the researchers to believe that the protective measures caused adverse reactions in female basketball players.17 Hardy et al18 and Ozer et al19 investigated the effectiveness of ankle prophylactics on balance and proprioception. Hardy et al18 had each participant complete three Star Excursion balance tests while wearing no brace, a semi-rigid brace, and a lace-up ankle brace. The Star Excursion balance tests consist of maintaining balance 48 while moving opposite leg in eight different directions. The researchers concluded that bracing had no effect at all on the balance during reaching tasks.18 Similarly, Ozer et al19 measured the effectiveness of not only bracing but ankle taping on balance, jumping, coordination, and proprioception. Each participant was tested for each variable while wearing no ankle devices barefoot, braces, and tapings. The results indicated that there were no significant differences between the braces or taping when compared to barefoot measures on any of the variables tested. The researchers concluded that either method is useful in preventing ankle injuries without altering functional performance.19 Both of these articles measured similar functional performance, yet they arrived at different conclusions. In addition to research that has been performed to date on ankle prophylactic affects on functional performance, there has been some research on the perceptions and/or placebo affect that may accompany these devices. Reuter et al20 compared four types of prophylactic devices (spatting, taping, bracing, and no taping/bracing) on athletes wearing football cleats. The researchers studied measurements of functional performance (maximal effort sprint and cutting drill) and feelings of comfort 49 and stability. The results found that the subjects perceived no support or the bracing as more comfortable and stable than either taping or spatting in the sprint, but found that no support was far less stable in the cutting drills than the other three conditions. There were no performance differences between any of the conditions. This led the researchers to conclude that spatting does not affect performance, is the same as taping in stability and comfort, and the same as bracing in stability but not comfort.20 Sawkins et al21 wanted to find out if there was a placebo effect in athletes who wear ankle taping and believe they will not be reinjured. The participants were tested under three conditions: no tape, real tape, and a placebo tape. They completed the Star Excursion balance test and a hopping test. The results indicated that there were no differences between the conditions in the functional tests. However, the researchers found that the subjects felt more confidence, stability, and reassurance when wearing both the placebo tape and the real tape. The researchers did not come to an actual conclusion, but stated that further research needs to be done in this area to determine if there is a placebo effect.21 50 Reliability of Injury Prevention The effectiveness of tape has long since been debated in research, with some experts saying that after a period of time the tape loosens up and is not effective any longer. In one study, Meana et al22 aimed to compare the effectiveness of ankle taping after a 30 minute training session. Ankle ROM was recorded before and after the training session. The results indicated that there was almost 50% decrease in ROM after the training session. The researchers concluded that further testing needs to be done in order to determine the effectiveness of wearing ankle taping in those who have no history of ankle injury.22 Another study completed by Delahunt et al23 examined the effects of a standard ankle taping on ankle joint movement in the frontal and sagittal plane on patients with chronic ankle instability. Each subject completed three drop landing tests under three conditions: no tape, taping, and post-exercise taping. The results indicated that there were no significant differences between pre and post exercise taping. Both taping conditions caused a decrease in the amount of plantarflexion after the drop landings. The researchers concluded that ankle taping may help to increase stability in the ankle.23 51 Mickel et al24 compared the use of bracing versus taping and the incidence of ankle sprains in one season of high school football season. The athletes were randomly placed into one of two groups: braced or taped every day. After the season, six ankle sprains had occurred and there was no significant difference between the two variables. In addition, the cost of using tape throughout the season compared to a one-time fee of ankle braces is significantly higher when using tape. The researchers concluded that using braces would be more efficient than using tape.24 Similarly, Frey et al25 completed a study that determined the effectiveness of ankle bracing on the frequency of ankle injuries in high school volleyball players over the course of one season. Subjects were separated into two groups: those who wear braces and those who do not wear braces as the control. The researchers used information about previous injury and sex to determine the results. They found that there were no differences between the frequency of ankle injuries between the two groups. However, they found that there were difference in protecting against re-injury for those who had a previous injury. The Aircast Sports Stirrup and Active Ankle Trainer II protected against injury with no history, but did not prevent injury to those who had prior history. Also, in the 52 female group there were significantly more injuries when wearing non-rigid braces compared to more rigid braces. The researchers concluded that this information is very helpful for people deciding on which ankle brace to use in volleyball.25 Summary The review of literature focuses on the importance and background of ankle prophylactics, clinical practice of taping and bracing, and ankle taping and bracing. Athletic trainers must choose between the two types of ankle prophylactics every day when preventing and treating ankle injuries. There is very little research that states what the preference of athletic trainers is for ankle prophylactics. However, research does state the similarities and differences between the two types. Both taping and bracing have little to no decrease in functional performance. According to research,3,7,9 bracing is a better option to use when one focuses on only injury prevention. Bracing tends to keep the foot in more stabilized, closed pact position longer than taping does.12,22 In addition, bracing is also a better option when looking at a cost standpoint. Buying 53 individual braces for each ankle is far cheaper than buying several boxes of tape.24 Since most of the research points to using bracing over taping as a better option, it is important to see if athletic trainers are following research or using tape more often. There are various other reasons that one would choose either device over the other, which should be determined as well. 54 APPENDIX B The Problem 55 STATEMENT OF THE PROBLEM The primary purpose of this study is to examine Certified Athletic Trainers use ankle prophylactics in the prevention and treatment of injury. It is important to examine this relationship because athletic trainers frequently use ankle taping and bracing and have specific reasons as to why they choose one over the other. Finding out if athletic trainers knowledge of the literature associated with ankle prophylactics corresponds with their preference in choosing between them can help to determine why an individual would or would not choose one device over the other. Additionally it would be beneficial for athletic trainers to assess their knowledge of the research and if they are up to date. Definition of Terms The following definitions of terms will be defined for this study: 1) Ankle Prophylactics – referring to types of ankle taping, bracing, or both completed for the prevention of injury26 56 2) Functional Performance – an individual’s personal skill in the following aspects: jumping, running, sprinting, balance, and agility26 3) Proprioception – the unconscious perception of movement and spatial orientation arising from stimuli within the body itself26 4) Neuromuscular Control – pertaining to stability and balance of both nerves and muscles26 5) Spatting – use of taping to prevent ankle injuries on the outside of a shoe26 Basic Assumptions The following are basic assumptions of this study: 1) All respondents will answer the survey honestly to the best of their ability. 2) All respondents will be given adequate time to complete the survey. 3) There will be an adequate return rate. Limitations of the Study The following are possible limitations of the study: 1) Only surveying Certified Athletic Trainers in high school and collegiate settings. 57 2) Only surveying Certified Athletic Trainers who are members of the National Athletic Trainers’ Association. 3) Opinions/knowledge may be skewed by the Athletic Trainers educational background. 4) Incorrect names or email addresses of Athletic Trainers could be included in the list serve. Significance of the Study Athletic trainers must choose between the two types of ankle prophylactics every day when preventing and treating ankle injuries. There is very little research that states what the preference of health care professionals is for ankle prophylactics. Both taping and bracing have little to no decrease in functional performance. According to research, bracing is a better option to use when one focuses on only injury prevention.3,7,9 Bracing tends to keep the foot in more stabilized, closed pact position longer than taping does.12,21 In addition, bracing is also a better option when looking at a cost standpoint.23 Buying individual braces for each ankle is far cheaper than buying several boxes of tape. Since most of the research points to using bracing over taping as a better option, it is important to see if 58 athletic trainers are following research or using tape more often. There are various other reasons that one would choose either device over the other, which should be determined as well. 59 APPENDIX C Additional Methods 60 APPENDIX C1 Panel of Experts Letter 61 Dear________________: I am a graduate athletic training student at California University of Pennsylvania pursuing a Master of Science degree in Athletic Training.

Design: Descriptive Survey Settings: Population-Based Survey Participants: There were 196 randomly selected ATCs currently working in the collegiate, high school, or high school/clinic setting as participants. INTERVENTIONS: The dependent variables were taping or bracing and preventing or post-injury prophylactic use. The independent variable was employment setting of athletic trainers and included high school, high school/clinic, and college. RESULTS: Statistical significance was found in two of the three hypotheses which indicate that athletic trainers from the collegiate setting choose to apply both bracing and taping after an acute ankle injury. In addition, a closed basket weave taping technique is the preferred ankle taping for collegiate athletic trainers to prevent injury. CONCLUSIONS: Based on the results of this study, we can conclude that collegiate athletic trainers have a similar preference of prophylactic device to prevent and treat ankle injuries.
