Effects of Vibration Frequencies in Rotator Cuff Syndrome

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.

Conditions

• Rotator Cuff Syndrome
• Vibration Therapy

Interventions

DEVICE

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

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.

OTHER

conventional physiotherapy program

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.
