The Effectiveness of Exercise Therapy and Dry Needling on Wrist Range of Motion, Pinch and Grip Force in Carpal Tunnel Syndrome: A Randomized Clinical Trial

Carpal tunnel syndrome (CTS) is the most prevalent form of peripheral neuropathy. There are various treatments for carpal tunnel.

In this study, we evaluated the effect of electroacupuncture and exercise on pinch and grip strength and wrist range of motion in patients with mild to moderate CTS.

Sixty patients with carpal tunnel syndrome were evaluated in this study, only five of whom were male. In this study, patients were divided into three groups. The control group consisted of 20 patients who only used splints in the second group, in addition to splints, special exercises were administered, and the third group, electroacupuncture, and brace were prescribed for 12 sessions of 40- minute duration. study time was 6 weeks. The parameters of pinch force, grip force, ROM (flexion and extension) were evaluated at baseline and after the treatment.

In this study, 55 women and 5 men with an average age of 49.23 ± 8.96 were enrolled. At the final follow up, significant improvements in all parameters were found in third groups (P < 0.05), except flexion of the wrist in the control group (P = 0.098). Our findings indicate that exercise therapy had more effect on ROM of flexion than acupuncture and acupuncture had more effect on pinching than exercise therapy but the effect sizes were weak. Also, the efficacy of splint alone was less than intervention groups in all parameters.

Results of this study demonstrated that adding exercise or acupuncture to nocturnal splinting, the functional improvement is more in patients with mild to moderate carpal tunnel syndrome and these interventions could be adopted in the management of these patients.
