Effect of the release exercise and exercise position in a patient with carpal tunnel syndrome

[Purpose] This study examined the effect of the release exercise and exercise position in carpal tunnel syndrome (CTS). [Subject] A 40-year-old, right-hand-dominant man presented with CTS, with pain and progressive tingling and numbness in the right hand. [Methods] The subject performed three exercises: (1) release, (2) wrist flexor stretching, and (3) wrist extensor stretching. In session 1, the subject performed exercises 2 and 3 in the standing position for 2 weeks. In session 2, the subject performed all three exercises in the supine position for 2 weeks. [Results] The pressure pain threshold decreased after session 1 and decreased further after session 2, and the Phalen's test and Tinel sign became progressively less positive. [Conclusion] Exercises in the supine position, including release exercises, are recommended for CTS.
