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.

| high intensity laser in addition to traditional physical therapy exercises | Other | high intensity laser will be used with 1064 nm wavelength and maximum of 25 W power. Analgesic and biostimulant modes were used in the present study. Also the patients will receive traditional physical therapy exercises in the form of flexibility and strengthening exercises for shoulder muscles. |
| Measure | Description | Time Frame |
|---|---|---|
| pain intensity | 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 | change from base line at three weeks |
| Measure | Description | Time Frame |
|---|---|---|
| shoulder range of motion | Flexion, abduction, and external rotation will be measured by using goniometer in a supine position and the active movements will be recorded. The goniometer will be centered at the acromion for abduction, greater tubercle for flexion, and olecranon for external rotation at 90° shoulder and elbow flexion | change from baseline at three weeks |

| low level laser in addition to traditional physical therapy exercises | Other | patients will receive low level Laser Therapy in addition to traditional physical therapy exercises. diode laser device with a wavelength of 850nm, power output of 100mV, continuous wave and 0.07cm2 spot area laser will be used. The laser will be applied with a dosage of 5 joule/cm2 (totally 15-20 joule) at the most 5 painful points for 1 minute at each point over subacromial region of the shoulder. Also the patients will receive traditional physical therapy exercises in the form of flexibility and strengthening exercises for shoulder muscles. |

| pain pressure threshold | Pressure Pain Threshold will be determined with an analogue algometer at the most painful point of the subacromial area. This point will be determined by a previous examination based on the point that the patient determined as 'his or her point of maximum pain'. | change from baseline at three weeks |
| Shoulder Pain and Disability Index | this scale will be used to assess functional status of the shoulder. The SPADI includes shoulder questions and consists of two subscales: pain and disability. Pain subscale consists of 5 items, and disability subscale consists of 8 items, and the total score is 0-100 | change from baseline at three weeks |
| Pittsburgh Sleep Quality Index (PSQI) | This scale assesses sleep quality and disorder and consists of seven subcomponents (subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, drug use, and daytime functions) and 19 items. Each component is evaluated on a score of 0-3 and is evaluated with a total sleep score ranging from 0 to 21, and high scores represent low sleep quality. A PSQI total score < 5 points is considered "good" sleep quality and > 5 points is "bad" sleep quality. | change from baseline at three weeks |
