The Effect of Kinesio Taping on Hand Functions in Zone V-VI Extensor Tendon Injuries

Investigation of the Effect of Kinesio Taping on Hand Functions in Zone V-VI Extensor Tendon Injuries: A Double-Blind Randomized Controlled Clinical Trial

This study aims to investigate the effects of Kinesio Taping (KT) on hand function in patients with Zone V-VI Extensor Digitorum Communis (EDC) tendon injuries following primary repair. Extensor tendon injuries in this region often lead to complications such as adhesion formation, reduced range of motion, extensor lag, and impaired hand function, despite standard rehabilitation approaches. Therefore, additional interventions that may enhance tendon gliding and neuromuscular control are of clinical interest.

In this double-blind randomized controlled trial, patients will be assigned to either a KT group or a sham taping control group. Both groups will receive a standardized postoperative rehabilitation program, while the intervention group will additionally receive KT applications between postoperative weeks 6 and 12. Outcome measures, including range of motion, grip and pinch strength, and functional hand performance, will be assessed at 12 and 24 weeks.

The study seeks to determine whether KT provides additional benefits beyond conventional rehabilitation in improving functional recovery after extensor tendon injuries, addressing an important gap in the current literature.
