Study Overview
Brief Summary
Shoulder pain is the third most common musculoskeletal problem after lumbar and neck diseases in clinical practice, and the most common cause of shoulder pain is subacromial impingement syndrome. The main goal of treatment is to reduce pain and to solve the mechanical problem that causes functional impairment. Low-level laser treatment is an increasingly used treatment modality in the treatment of subacromial impingement syndrome as in many musculoskeletal diseases, as it promotes cell proliferation and tissue regeneration by its anti-inflammatory and photobiostimulation properties. Also, High-intensity laser therapy is a treatment method that is gaining popularity in the recent years. These ultra-short impulses effect a deep action in the biological tissue (3-4 cm), with a homogeneous distribution of the light source in the irradiated soft tissue, but without excessive thermal enhancements. It reduces pain and edema with photomechanic effects in deep tissues. As far as the investigators know, there are no studies comparing these two treatment modalities in subacromial impingement syndrome yet. This study was planned to compare the efficacy of High-intensity laser therapy and low-intensity laser therapy in treatment of patients with subacromial impingement syndrome.

Arms & Interventions
low laser group
Intervention: low level laser in addition to traditional physical therapy exercises (Other)
control group
Intervention: traditional physical therapy exercises (Other)
High laser group
Intervention: high intensity laser in addition to traditional physical therapy exercises (Other)
Outcomes
Primary Outcomes
pain intensity
Time Frame: change from base line at three weeks
Pain will be evaluated by a visual analogue scale (VAS). The patient will be asked to mark the severity of pain on a 100-mm line with "no pain" on one end and "most unbearable pain" on the other end
Secondary Outcomes
- pain pressure threshold(change from baseline at three weeks)
- Pittsburgh Sleep Quality Index (PSQI)(change from baseline at three weeks)
- shoulder range of motion(change from baseline at three weeks)
- Shoulder Pain and Disability Index(change from baseline at three weeks)
