About this study

Official title: Efficacy and Safety of Digital Therapeutics for Improving Shoulder Function After Rotator Cuff Repair: A Prospective, Randomized, Parallel-Group, Evaluator-Blinded Study

  1. Importance of Rehabilitation After Rotator Cuff Repair Rotator cuff tears are among the most common shoulder conditions in Korea. They can occur naturally with aging or result from trauma or overuse. When conservative treatments like medication or injections fail to relieve pain and restore function, rotator cuff repair surgery is necessary. Postoperative rehabilitation exercises are crucial for recovering shoulder function, reducing pain, and returning to daily activities. Many studies have emphasized the importance of staged rehabilitation and patient education after surgery, showing that active patient participation directly affects recovery. However, some patients rely on unverified internet sources (such as YouTube or online forums) or face limitations such as time, geographical constraints, or cost even when receiving face-to-face therapy.
  2. Advantages of Digital Therapeutics Digital therapeutic devices have emerged as a promising solution to these challenges. These smartphone applications deliver exercise and educational content tailored to postoperative rehabilitation, aiming to improve the disease state. They offer anytime, anywhere access without time or location restrictions and provide evidence-based, systematic, and personalized rehabilitation programs. Comprehensive educational materials enhance patient understanding and promote self-management skills, potentially increasing rehabilitation adherence.
  3. Recent Research Findings Digital rehabilitation programs for patients after rotator cuff repair have demonstrated effectiveness. Programs that provide real-time exercise feedback using mobile apps and sensors have shown similar or superior outcomes compared to traditional physical therapy. Augmented reality (AR)-based rehab systems are more effective in improving shoulder function than conventional methods, and digital apps offering customized exercise videos significantly enhance physical function and confidence. Notably, patients using digital rehabilitation programs for 1 to 6 months exhibited improved adherence to therapeutic exercises, facilitating consistent home-based rehabilitation.
  4. Purpose of This Clinical Trial While previous studies have confirmed the efficacy and safety of digital therapeutic devices after rotator cuff surgery, most are limited to generic exercise programs. This clinical trial aims to evaluate the effectiveness and safety of a clinical trial digital therapeutic device not yet approved domestically, providing disease-specific exercise programs.

What participants receive

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

  • digital therapeuticsOther

    After rotator cuff repair surgery, the patient performed prescribed rehabilitation exercises delivered through a personal mobile device

  • usual careOther

    Before discharge and at the first postoperative visit (2 weeks after surgery), patients receive education based on a brochure covering rehabilitation exercises, surgical site care, and criteria for hospital visits in emergency situations. The brochure includes information on the duration of brace use, surgical site hygiene and care, precautions for arm use, and detailed rehabilitation exercise instructions.

    At follow-up visits around 8 and 20 weeks post-surgery, patients receive guidance on improving joint range of motion and muscle strengthening exercises. Physical therapy modalities such as cold and heat application and electrical stimulation are provided. Additional treatments, including corticosteroid injections combined with hyaluronic acid, may be administered based on the healthcare provider's clinical judgment.

What is being measured

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

  1. American Shoulder and Elbow Surgeons score (ASES)

    domain : pain, function

    1. Pain is measured using a Visual Analog Scale (VAS) rated out of 10 points and then converted to a 50-point scale.
    2. Function is assessed through a questionnaire consisting of 10 items, each scored from 0 to 3, with a total raw score of 30. This total is converted to a 50-point scale.

    This results in a final combined score ranging from 0 to 100, with higher scores indicating better shoulder function.

    Measured: baseline, 9-week, 15-week, 22-week, 46-week

Secondary outcomes (9)
  1. Constant score

    The scoring system ranges from 0 to 100 points, with higher scores indicating better shoulder function. It includes the following components: pain (15 points), activities of daily living (20 points), active range of motion (ROM) (40 points), and muscle strength (25 points). Muscle strength is measured by assessing force in 90-degree shoulder abduction and then converted into a score.

    Measured: baseline, 9-week, 22-week, 46-week

  2. Korean shoulder Score (KSS)

    The scale ranges from 0 to 100 points, with higher scores indicating better function. It is composed of the following components: pain (30 points), function (40 points), activities of daily living (10 points), muscle strength (20 points), and satisfaction (10 points).

    Measured: baseline, 9-week, 22-week, 46-week

  3. Simple shoulder Test (SST)

    The score ranges from 0 to 12 points, with higher scores indicating better function. It is an outcome measure consisting of 12 yes/no questions related to function. Each "yes" response is scored as 1 point, and the total number of "yes" answers is summed to calculate the final score. This tool provides a simple patient-reported outcome to briefly assess the ability to perform daily activities.

    Measured: baseline, 9-week, 22-week, 46-week

  4. Shoulder pain (PVAS)

    Evaluated during rest and activity. Pain is assessed using an 11-point scale (0-10 points) evaluating overall shoulder pain over the past 7 days. A lower score indicates an improvement in pain.

    Measured: baseline, 9-week, 15-week, 22-week, 46-week

  5. Shoulder joint range of motion (active)

    1. Forward flexion (0-180 degrees), abduction (0-180 degrees), and external rotation at the side with the upper arm beside the torso (0-90 degrees) are measured using a goniometer to record the maximum angles. Higher values indicate better shoulder mobility.
    2. Internal rotation at the back: When the arm is placed behind the back, the level of the spine reached by the tip of the thumb is measured and scored accordingly (thoracic vertebrae T1-T12 = 1-12 points; lumbar vertebrae L1-L5 = 13-17 points; buttock = 18 points). Higher scores indicate better shoulder mobility.

    Measured: 9-week, 15-week, 22-week, 46-week

  6. Shoulder joint range of motion (passive)

    1. Forward flexion (0-180 degrees), abduction (0-180 degrees), and external rotation at the side with the upper arm beside the torso (0-90 degrees) are measured using a goniometer to record the maximum angles. Higher values indicate better shoulder mobility.
    2. Internal rotation at the back: When the arm is placed behind the back, the level of the spine reached by the tip of the thumb is measured and scored accordingly (thoracic vertebrae T1-T12 = 1-12 points; lumbar vertebrae L1-L5 = 13-17 points; buttock = 18 points). Higher scores indicate better shoulder mobility.

    Measured: baseline, 9-week, 15-week, 22-week, 46-week

  7. Shoulder muscle strength (Isokinetic)

    Isokinetic muscle strength is measured for each movement following a standardized protocol using an isokinetic dynamometer (HUMAN NORM; exercise testing and evaluation device; classification number A30130.01, Class 2 medical device). During the test, the subject sits on a chair with the trunk fixed to the dynamometer. The subject holds the handle on the opposite side of the dynamometer. Higher values indicate better muscle strength.

    Internal and external rotation: The arm is abducted to 45 degrees in the scapular plane with the elbow flexed to 90 degrees. External rotation range of motion is set at 65 degrees and internal rotation at 25 degrees. Measurements are taken at an angular velocity of 60 degrees per second for 4 repetitions (strength) and 180 degrees per second for 10 repetitions (muscular endurance), recording peak torque in pounds.

    Measured: baseline, 22-week, 46-week

  8. Shoulder muscle strength (Isometric)

    Using a hand-held dynamometer (FGN-20B, SHIMPO, JAPAN), the maximum force (in pounds) is collected and measured in the internal rotation (at side), external rotation (at side), and scaption positions.

    Measured: baseline, 9-week, 22-week, 46-week

  9. Global change rating (GRoC)

    The overall change assessment scale ranges from -5 (much worse) to 5 (much improved) points, evaluating the patient's perception of overall functional recovery and satisfaction with their general condition. Compared to pre-surgery, a change of 2 points or more at the end of intervention (T3), and similarly from T3 to the end of follow-up (T4), is interpreted as the minimum clinically important difference.

    Measured: 22-week, 46-week
