Background: Adhesive capsulitis is a prevalent shoulder condition characterized by pain, progressive stiffness, and restricted range of motion, particularly in abduction and external rotation. These limitations significantly affect daily activities and overall quality of life. Capsular tightness, myofascial trigger points, and altered shoulder biomechanics contribute to persistent symptoms and delayed recovery.

Objective: To evaluate the effectiveness of a combined physiotherapy approach involving dry needling, Mulligan mobilization with movement, and interferential stimulation therapy in reducing pain and improving shoulder mobility and functional ability in a patient with adhesive capsulitis.

Methodology: This single-subject case study involved a 45-year-old female diagnosed with right-sided adhesive capsulitis. The intervention was delivered over four weeks, with five sessions per week. Treatment included dry needling of selected shoulder muscle trigger points, Mulligan mobilization with movement targeting shoulder abduction and external rotation, interferential stimulation therapy for pain relief, and a structured exercise program. Outcome measures comprised the Numeric Pain Rating Scale (NPRS), goniometric assessment of shoulder range of motion, and the Shoulder Pain and Disability Index (SPADI).

Results: After four weeks of intervention, the patient showed a significant reduction in pain levels, notable improvements in shoulder abduction, external rotation, and flexion, and a marked decrease in SPADI scores, reflecting improved functional ability. Enhanced movement tolerance and increased participation in daily activities were also observed.
