Introduction
Carpal Tunnel Syndrome (CTS) is one of the most widely-known
and most common UE diagnosis that is caused by compression to
the median nerve. This disease has a significant impact on the work
force as it heavily affects those who perform repetitive wrist motion
within their line of work (e.g. hairdresser). In recent years, the
common approach in treating CTS involved splinting, injections,
and/or other various conservative therapy treatments. Over the past
few years there has been an apparent increase in the use of
Kinesiotaping, and few RCT’s have been conducted to investigate
Kinesiotape’s effects towards treating CTS. While some research
has been conducted, there is no evidence of a SR. Therefore, the
purpose of this review is to determine Kinesio tape’s effect on
improving CTS pain levels, symptom severity, and patient function
measured by the Visual Analog Scale (VAS) and the Boston Carpal
Tunnel Questionnaire’s (BCTQ) symptom severity and function subsections.

Methodological rating of the RCT’s were completed using the
PEDro criterion score. At least 2 raters read each of the 5
articles and were blinded to individual PEDro scores. No
disagreements between raters were evident. Articles meeting
the cutoff PEDro criterion score (>7) were then identified with
the weighted average standardized effect size (SES)
calculated for control and intervention groups. Sensitivity
analysis was completed by removing the study with the
largest sample size and re-calculating weighted average
SES.

●As noted by the forest plots, the combined weighted SES for KT groups
were all considered large, as all 3 groups exceeded the ‘large SES’ cutoff score of 0.8. The combined weighted SES for control groups for CTS
symptom severity and function fell below this same SES cut-off but
showed a large SES for pain levels.
●Individual t-tests were conducted, and no significant differences
between groups were found in any of the 3 outcome measures (⍺=0.05;
CI=95%: Symptom Severity: p = 0.5590, Function: p = 0.7327,
Pain : p = 0.3591).
●Findings show a more favorable improvement towards the KT groups
noted by the MCID scores (Tables 6, 7, & 8) for BCTQ-F, BCTQ-S, and
VAS.

Discussion
●All KT groups demonstrated large effect sizes (>0.8). The researchers
recognize that even small effect sizes may still provide clinical
meaningfulness to a clinician. Although exercise alone groups showed
moderate effects sizes, the data presented in this SR suggests that KT
was favorable to exercise alone. Individual t-tests were conducted and
indicated no statistically significant difference between the groups, but
that is not to say that the KT treatment was not more favorable.
●Limitations:. KT, being a broad term that encompasses many different
names, can be used for various treatment strategies which may have
caused the search keywords to be too specific or too broad. Limited to an
initial small amount of total articles to review resulting in a lower than
desired amount of studies for each data set.
●Clinical implications: KT may assist relief in pain, symptom severity,
and/or improve function. This study recognizes that some clinicians may
only be interested in 1 of the 3 dependent variables presented in our
research, and the data does allow the use of KT in conjunction with
empirical evidence from the clinician/researcher. Both groups in each
study received the same exercises, but as the control groups showed
improvement noted by MCID scores, the data suggest greater favorability
towards the KT groups noted by SES.
●Future research: Specifically compare other interventions to KT such
as: splinting, physical agent modalities, casting, and/or surgery. This
study primarily focused on KT groups being compared to placebo-KT
groups that received only exercise.

Conclusion
Significant findings within
each group but not between
groups.

Favors Control

Favors Treatment

BCTQ-S Improvement

KT may be an effective intervention to improve CTS pain, symptom
severity, and function, but may not be more superior than other
conservative interventions as there were no significant differences
between groups for all 3 outcome measures conducted in the SR.
