Kinesio taping as an alternative treatment for manual laborers with carpal tunnel syndrome: A double-blind randomized clinical trial.

BACKGROUND

Carpal tunnel syndrome (CTS) is one of the most common forms of peripheral neuropathies due to median nerve compression. Occupational factors, such as repetitive hand motions are believed to be associated with this condition.

OBJECTIVE

This clinical trial assessed the effect of Kinesio taping (KT) of hand flexor muscles on the management of mild to moderate CTS in Iranian manual laborers.

METHODS

Thirty manual laborers with mild to moderate CTS participated in this clinical trial. They were assigned to an intervention or a control group. The treatment consisted of a 2-week KT followed by a 4-week follow-up. The control group received sham KT without tension applied. Boston Carpal Tunnel Questionnaire scores, pinch and grip force tests, and electrophysiological examination of the median nerve were performed for each participant at baseline, 24 to 48 hours, and two to four weeks of follow-up. The statistical analysis of variance was performed (2 groups × 5 times) for all participants, comparing differences in the data within and between the two groups.

RESULTS

The baseline assessment revealed no inter-group differences in the clinical outcomes (P> 0.05). Comparisons of the changes in the electro-physiological and functional variables indicated significantly greater improvement in the KT group than in the sham counterpart (P< 0.05). No statically significant improvement was evident by the electrodiagnostic criteria in the sham-KT group (P> 0.05).

CONCLUSIONS

KT is an effective, safe, reliable, and conservative therapeutic choice for the management of patients with CTS. The treatment does not restrict the daily activities of patients nor has it any side effects.
