High-intensity Laser Therapy Versus Extracorporeal Shock Wave on Tendon Thickness and Occupation Ratio In Patients With Chronic Supraspinatus Tendinopathy

This study will be conducted to investigate the difference between high-intensity laser and extracorporeal shock wave on supraspinatus tendon thickness, subacromial space, occupation ratio, shoulder pain intensity, shoulder range of motion (ROM), hand strength, and functional disability in patients with chronic supraspinatus tendinopathy.

Inclusion Criteria: * Patients from 18 to 50 years old of both genders. * Unilateral Chronic Supraspinatus Tendinitis in dominant side * BMI 18.5-24.9 * Tenderness is found over the supraspinatus as it passes subacromial and anterolateral The patient will report pain with active shoulder elevation in the scapular plane (eg: welders, plate workers, slaughterhouse workers and overhead playing athletes) * The patient will report pain with resisted isometric abduction. * The patient will report positive Jobe's test (empty can test) Exclusion Criteria: * Post shoulder surgery, traumatic incidents * Partial tears at surgery * Massive retracted tears at surgery * Frozen shoulder Rotator cuff tear * Glenohumeral or acromioclavicular arthritis * Implanted pacemaker * Pregnancy
