Objectives: To evaluate the effects of dry needling on pain and function in patients with concurrent carpal tunnel syndrome (CTS) and forearm muscles myofascial trigger point (MTrP).

Materials and Methods: In this randomized controlled trial, fifty affected hands with clinical and electro-diagnostic diagnosis of mild and moderate CTS with presence of MTrP in their forearm muscles were enrolled. Patients were randomized to intervention and control groups.In the intervention group, in addition to wrist splint, one session forearm MTrP dry needling was performed. Pain and function was assessed using visual analogue scale (VAS) and Boston carpal tunnel questionnaire(BCTQ) at the baseline, one and six weeks after intervention in both groups.The outcomes in this study were pain reduction (VAS) and improvement in hand function (BCTQ).

Results: Co-occurrence of mild and moderate CTS with forearm muscles MTrP were observed in 61% of cases.  Improvement in pain severity, VAS, mean difference 1.44 (95% CI: (0.96, 1.92 )),(p < 0.001),BCTQ total score, mean difference 0.21 (95% CI: (0.10, 0.32)),(p<0.001) were observed in dry needling group in compare with control group at one week follow up.

Conclusion: Forearm MTrP should be considered when examining patients with CTS. MTrP therapy in patients with CTS can enhance the effectiveness of physical therapy on symptom improvement at short term.
