Abstract

Background. Carpal tunnel syndrome (CTS) is a major health issue that can impede postpartum women's activities and skills in both their personal and professional lives. Purpose. To compare the effectiveness of low-level laser therapy (LLLT) and pulsed ultrasound (US) in relieving postpartum CTS. Methods. Forty-eight women with mild to moderate CTS were divided into three groups. In addition to wrist exercises, Group (A) (n = 16) received LLLT, Group (B) (n = 16) received pulsed US, and Group (C) (n = 16) performed wrist exercises alone. For all groups, the treatment sessions were applied to the affected hand, 3 sessions weekly for four weeks. All postpartum women were evaluated pre- and post-treatment via a visual analogue scale (VAS) for pain intensity, the Boston Questionnaire of CTS (BCTS) for diagnosing CTS symptoms, electromyography for measuring motor conduction velocity (MCV), sensory conduction velocity (SCV), motor distal latency (MDL), and sensory peak latency (SPL), and a hand grip dynamometer for assessing hand grip strength. Results. All measured variables were significantly improved in the three groups post-treatment compared to pre-treatment. Between-groups comparison showed a highly significant decrease in the VAS, BCTS, and SPL and a significant increase of SCV and hand grip strength between groups A and C in favor of group A and between groups B and C in favor of group B, while the significant change in MDL and MCV was found between groups A and C only in favor of group A (p < 0.05), with no significant change in all outcome measures between groups A and B (P > 0.05). Conclusion. Either LLLT or pulsed US are useful modalities that can be used as an effective conservative therapy for alleviating postpartum CTS.
