스마트폰 사용으로 인한 손목 통증 환자에게 멀리건 자가활주 동반 움직임 기법 적용이 통증 및 악력과 기능에 미치는 영향 = The Effects of Mulligan Self-Mobilization with Movement on Pain, Grip Strength, and Function in Patients with Wrist Pain due to Smartphone Use

다국어 초록 (Multilingual Abstract)

Background: Prolonged smartphone use is a primary cause of wrist pain and functional limitations, leading to a global increase in musculoskeletal disorders. While Mulligan's mobilization with movement (MWM) is an established manual therapy, research on its patient-applied variant, Self-MWM, for this condition remains limited. This study determined the effects of Self-MWM on pain, grip strength, and function in patients with chronic wrist pain from smartphone use.
Methods: Forty adults with chronic smartphone-related wrist pain were randomized into a Self-MWM group and a control group performing general stretching and strengthening. Both groups received basic physical therapy (heat and electrical therapy) for 30 minutes, three times weekly for 6 weeks. Outcomes were measured pre- and post-intervention using the visual analog scale (VAS) for pain, a hand-held dynamometer for grip strength (GS), and the disabilities of the arm, shoulder and hand (DASH) questionnaire for function.
Results: After 6 weeks, both the Self-MWM and control groups showed statistically significant improvements in pain, grip strength, and function. However, the Self-MWM group demonstrated markedly greater improvements across all measures. Pain reduction, grip strength gain, and functional enhancement were substantially more pronounced in the Self-MWM group, with the differences in improvement between the groups being highly significant (p<.001).
Conclusion: Integrating Self-MWM into a standard physical therapy protocol is significantly more effective for managing pain, improving grip strength, and restoring function in patients with smartphone-induced wrist pain. This approach offers a practical, powerful self-management tool for this prevalent musculoskeletal concern.
