In this study, 27 female patients suffering from carpal tunnel syndrome were divided into two groups: one that used only a night wrist splint and another that received additional acupuncture therapy. The measurements were taken from 45 limbs and included a visual analogue scale, the Duruöz Hand Index, and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire scores. In addition, electrophysiological measurements and observation of the median nerve's cross-sectional area were taken before and after the treatment.

Following the treatment, improvements were observed in both groups according to the visual analogue scale, the Duruöz Hand Index and Quick Disabilities of the Arm, Shoulder and Hand questionnaire scores, and the electrophysiological measurements. However, a significant decrease was noted solely in the cross-sectional area of the median nerve in the acupuncture group, while the control group that only used the wrist splint showed no changes. Thus, it was concluded that acupuncture therapy provided both clinical and morphological benefits to patients with carpal tunnel syndrome.
