Effect of Mobilization With Movement in Patients With Rotator Cuff Lesions

Participants assigned to the Mobilization with Movement (MWM) group will receive manual therapy based on the Mulligan concept. The intervention will consist of the application of sustained, pain-free accessory mobilization to the glenohumeral joint combined with active physiological shoulder movements, primarily in shoulder flexion and abduction. The direction and grade of mobilization will be individually determined according to the patient's symptoms and movement restrictions, ensuring that all movements are performed within a pain-free range. MWM interventions will be administered by a trained physiotherapist following a standardized treatment protocol. Each treatment session will last approximately 20-30 minutes and will be applied multiple times per week throughout the intervention period. The primary goal of the intervention is to improve joint mechanics, reduce pain, and enhance proprioceptive input by facilitating normal, pain-free movement patterns.

Participants allocated to the conventional physiotherapy group will receive a standard rehabilitation program commonly used for rotator cuff lesions. The intervention will include therapeutic exercises targeting shoulder range of motion, strengthening of the rotator cuff and scapular stabilizing muscles, and stretching exercises for periarticular soft tissues. Physical therapy modalities such as heat or ultrasound may be applied as needed for pain management. This intervention will be delivered by a physiotherapist according to established clinical guidelines. Mobilization with Movement or other Mulligan-based manual therapy techniques will not be included in this group.
