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.

Conditions

Subacromial Impingement Syndrome

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

High laser group

Group Type: EXPERIMENTAL

high intensity laser in addition to traditional physical therapy exercises

Intervention Type: 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.

low laser group

Group Type: EXPERIMENTAL

low level laser in addition to traditional physical therapy exercises

Intervention Type: 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.
