Vibration Therapy and IASTM in Subacromial Impingement Syndrome

Plain-language summary

This randomized controlled clinical study aims to investigate the effects of vibration therapy and instrument-assisted soft tissue mobilization (IASTM), when added to conventional physiotherapy, on pain, range of motion, proprioception, functional status, and quality of life in individuals diagnosed with subacromial impingement syndrome (SAIS). SAIS is one of the most common causes of shoulder pain and is frequently associated with impaired scapular kinematics, rotator cuff dysfunction, soft tissue tightness, and decreased shoulder mobility. A total of 48 participants aged 40-60 years with MRI-confirmed SAIS will be randomly assigned into three groups: (1) Vibration Therapy + Conventional Physiotherapy, (2) IASTM + Conventional Physiotherapy, and (3) Conventional Physiotherapy (Control). All interventions will be administered three times per week for four weeks. Outcomes include pain intensity (VAS), shoulder range of motion (Goniometer Pro app), proprioception at 60° of flexion and abduction, functional status (DASH), and quality of life (RC-QoL). The study aims to determine whether adding vibration therapy or IASTM to standard physiotherapy provides additional short-term benefits in reducing pain, improving joint mobility, enhancing proprioceptive acuity, and increasing functional capacity in individuals with subacromial impingement syndrome.
