Effects of Vibration Frequencies in Rotator Cuff Syndrome

Rotator cuff syndrome is a common shoulder disorder caused by excessive use, muscle weakness, trauma, or instability. It often results in pain, restricted movement, and reduced functional capacity. The condition is associated with subacromial space compression, leading to tendinitis, partial tears, or full rupture, which affects daily activities and overall quality of life. Percussion massage therapy is an emerging treatment method that combines elements of traditional massage and vibration therapy. Introduced in the 1950s by Robert Fulford, it was later developed into handheld devices for self-administered and professional use. Percussion therapy is believed to reduce pain, enhance circulation, improve tissue healing, decrease muscle spasms, and increase joint range of motion (ROM). However, scientific evidence regarding its effectiveness, particularly in rotator cuff syndrome, remains limited. This study aims to investigate the effects of different frequencies of vibration therapy applied with a percussion massage gun on pain, ROM, functionality, joint position sense, and quality of life in individuals with rotator cuff syndrome.
