The aim of this study was to assess the effect of combination of low level laser therapy (LLLT), ultrasound and exercise therapy on shoulder tendinitis. 62 female patients with shoulder tendinitis (35-65 years) participated in this study and were randomly assigned into 3 groups. All groups completed 10 sessions, 3 sessions per week, of treatment as following: Group A (ultrasound plus exercise), Group B (830 nm laser, ultrasound plus exercise), Group C (780nm laser, ultrasound plus exercise). Outcome measures: Clinical assessments such as pain severity through visual analogue scale (VAS), Tenderness, Functional Recovery (FR) and Manual Muscle Testing (MMT) were performed at the baseline, before treatment, and at the end of treatment. Follow-up were done, one and three months after treatment period based on the degree of recovery and satisfaction of patients.
