About this study

Official title: The Effects of Vibration Therapy at Different Frequencies on Pain, Range of Motion, Functionality, Joint Position Sense, and Quality of Life in Individuals With Rotator Cuff Syndrome

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 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.

  • conventional physiotherapy programOther

    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.

Study groups in NCT06899945
Study groupRoleWhat they receive
Control Group (Conventional Physiotherapy)Active comparatorParticipants in the control group will receive only conventional physiotherapy without vibration therapy. This ensures a baseline comparison to assess the effectiveness of vibration therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 3 weeks

Secondary outcomes (4)
  1. Visual Analogue Scale

    Visual Analogue Scale (VAS) will be used to evaluate the pain intensity of patients. VAS consists of a 10 cm long horizontal line. '0' represents no pain, '10' represents unbearable pain. During our evaluation, patients will be asked to mark the level of pain they feel on this chart, and the distance to the starting point will be measured and recorded with the ruler.

    Measured: 3 weeks

  2. Range of Motion

    The shoulder range of motion (ROM) of the participants included in the study will be measured using the Fizyosoft Extremity ROM system.

    The measurements will be recorded as follows:

    Flexion and abduction: 0-180 degrees Internal and external rotation: 0-90 degrees.

    Measured: 3 weeks

  3. Disabilities of the Arm, Shoulder, and Hand Questionnaire

    The DASH questionnaire is used to assess physical disability and functionality in upper extremity injuries. It consists of three subcategories:

    The first section contains 30 questions measuring functional and symptom scores, including:

    21 questions evaluating daily living activities, 5 questions assessing symptoms (pain, activity-related pain, tingling, weakness, and movement restriction), 4 questions related to social function, work, sleep, and self-confidence. The work module consists of 4 additional questions, evaluating the participant's ability to perform work-related tasks.

    Each question is answered using a 5-point Likert scale:

    1. = No difficulty
    2. = Mild difficulty
    3. = Moderate difficulty
    4. = Severe difficulty
    5. = Unable to perform the activity A higher total score indicates a greater level of disability.

    Measured: 3 weeks

  4. Assessment of Quality of Life

    The Rotator Cuff Quality of Life (RC-QoL) questionnaire was developed by Hollishead et al. and was validated for the Turkish population by Çınar-Medeni et al. in 2015. This questionnaire is a specific assessment tool designed to evaluate the quality of life in individuals with rotator cuff pathology.

    The scale consists of 34 questions categorized into five sections:

    Physical symptoms Work-related activities Daily living activities Social aspects Emotional well-being

    Each question is scored on a scale from 0 to 100, where:

    0 = Severe pain or impairment 100 = No pain or impairment A higher score indicates better quality of life. The total score is calculated by summing the scores of the answered questions, dividing by the number of answered questions, and converting the result into a percentage.

    Measured: 3 weeks
