Effects of High Intensity Laser Therapy (HILT) in Patients With Subacromial Impingement Syndrome

The aim of this study is to determine the effects of high intensity laser therapy (HILT) in patients with subacromial impingement syndrome (SIS). This study aims to compare the effects of HILT alone and HILT and therapeutic exercise combination on shoulder pain, ROM, joint position sense (JPS), muscle strength and function.The investigators hypothesized that shoulder pain, ROM, JPS, muscle strength and functionality would improve with both treatments but that HILT combined with exercise would result in better outcomes than HILT alone.
