Brief Summary

This study aims to investigate the effects of vibration therapy applied at different frequencies using a percussion massage gun on pain, range of motion (ROM), functionality, joint position sense, and quality of life in individuals with rotator cuff syndrome. Rotator cuff syndrome is a common shoulder disorder caused by excessive use, muscle weakness, trauma, or instability, leading to pain, restricted movement, and reduced functional capacity. Although percussion massage therapy has gained popularity for its potential therapeutic benefits, there is limited scientific evidence on its effectiveness in improving ROM, pain reduction, and functional outcomes. A total of 48 participants diagnosed with rotator cuff lesions will be included in the study and divided into three groups: Vibration Group (33 Hz) Vibration Group (16.7 Hz) Control Group (Conventional Physiotherapy) The intervention will include: Conventional physiotherapy exercises applied to all groups, Vibration therapy with a percussion massage gun applied to the experimental groups, targeting the deltoid, supraspinatus, infraspinatus, and teres minor muscles for three minutes per muscle, three times per week for three weeks. Outcome Measures: Pain: Visual Analog Scale (VAS) ROM \& Joint Position Sense: Measured using the Goniometer Pro mobile application Functionality: Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire Quality of Life: Rotator Cuff Quality of Life (RC-QoL) questionnaire Hypotheses: Vibration therapy at different frequencies will significantly impact pain, ROM, functionality, joint position sense, and quality of life. 33 Hz vibration therapy will be more effective than 16.7 Hz in improving outcomes. The data will be analyzed using SPSS 25, with statistical tests applied based on data distribution. This research aims to contribute to the understanding of vibration therapy's role in managing rotator cuff syndrome and its effectiveness in clinical rehabilitation.

Outcome Measures

Primary Outcomes (1)

• Evaluation of Joint Position Sense

  The joint position sense of the participants in the study will be measured using the Fizyosoft Extremity ROM system. Joint position sense will be evaluated in 60-degree shoulder flexion and abduction movements. Participants will be asked to lift their arm to 60 degrees with their eyes open and remember the position. Then, they will be instructed to replicate the same movement with their eyes closed. The shoulder angle will be measured while their eyes are closed. The difference between the open-eye and closed-eye measurements will be recorded as the joint position sense. This method will be applied at 60-degree shoulder flexion and abduction .The average of two trials will consider for data evaluation.

Study Arms (3)

Control Group (Conventional Physiotherapy)

ACTIVE COMPARATOR

Participants in the control group will receive only conventional physiotherapy without vibration therapy. This ensures a baseline comparison to assess the effectiveness of vibration therapy. Treatment Modalities: TENS therapy (20 minutes, 100 Hz) Mobility exercises (wand exercises, Codman exercises, active/passive stretching) Strengthening exercises (theraband-based training) Frequency: 5 sessions per week Total Treatment Period: 3 weeks

Other: conventional physiotherapy program

Vibration Therapy (16.7 Hz) Group

EXPERIMENTAL

This group will receive vibration therapy at 16.7 Hz using a percussion massage gun (Hypervolt device (Hyperice, CA, USA)) along with a standard physiotherapy program. The treatment protocol mirrors the 33 Hz group, except for the vibration frequency. Duration: 3 minutes per muscle Frequency: 3 times per week Total Treatment Period: 3 weeks Additional Treatment: Standard physiotherapy (TENS, mobility exercises, and strengthening)

Device: a percussion massage gun (Hypervolt device (Hyperice, CA, USA)); Other: conventional physiotherapy program

Vibration Therapy (33 Hz) Group

EXPERIMENTAL

Participants in this group will receive vibration therapy at 33 Hz using a percussion massage gun (Hypervolt device (Hyperice, CA, USA)) in addition to a standard physiotherapy program. The therapy will target the deltoid, supraspinatus, infraspinatus, and teres minor muscles, applying vibration along the origin-insertion pathway. Duration: 3 minutes per muscle Frequency: 3 times per week Total Treatment Period: 3 weeks Additional Treatment: Standard physiotherapy (TENS, mobility exercises, and strengthening)

Device: a percussion massage gun (Hypervolt device (Hyperice, CA, USA)); Other: conventional physiotherapy program

Interventions

a percussion massage gun (Hypervolt device (Hyperice, CA, USA)) DEVICE

Vibration application will be applied to the individuals in this group in addition to conventional methods. Vibration application will be applied to the deltoid, supraspinatus, infraspinatus, and teres minor muscles with a percussion massage gun (Hypervolt device (Hyperice, CA, USA)) along the origo-insertio line for 3 minutes for each muscle group. Vibration application will be performed using the soft head of the percussion massage gun. Vibration therapy will be applied 3 days a week for 3 weeks.

Vibration Therapy (16.7 Hz) Group; Vibration Therapy (33 Hz) Group

conventional physiotherapy program OTHER

Participants in the conventional physiotherapy program will follow a 3-week exercise plan, with sessions 5 days per week, each lasting 30 minutes under physiotherapist supervision. Treatment includes: TENS therapy (20 min, 100 Hz) on the painful area. Wand exercises for flexion, abduction, extension, internal, and external rotation (10 reps/set). Codman exercises for flexion, abduction, and circular movements (10 reps/set). Active \& passive stretching for flexion, abduction, internal, and external rotation (10 reps/set). Finger ladder exercises for flexion and abduction (10 reps/set). Strengthening with a theraband for flexion, abduction, external/internal rotation, and extension, adjusted based on progress (10 reps/set). This exercise program will be applied to all study groups.
