About this trial
This study will examine whether rigid taping applied to the acromioclavicular (AC) joint can reduce shoulder pain and improve shoulder function in people with AC joint degeneration. Participants with shoulder pain and a confirmed diagnosis of AC joint degeneration will be randomly assigned to one of two groups: (1) rigid taping plus a standardized exercise program or (2) the same exercise program without taping. The program will last 4 weeks, with weekly supervised visits. Pain, shoulder motion, and shoulder function will be assessed at baseline, after the first session (acute effect), at the end of treatment (Week 4), and at a 3-month follow-up.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
A clinical diagnosis of acromioclavicular (AC) joint degeneration confirmed by clinical examination and imaging (X-ray, ultrasound, or MRI).
Shoulder pain duration of at least 4 weeks.
Age between 18 and 65 years
Willingness to refrain from any additional treatments outside the study protocol during the study period (e.g., medication changes, injections, or physiotherapy elsewhere) and to provide written informed consent
Disqualifiers
Current or previous diagnosis/history of acromioclavicular (AC) joint separation.
Diagnosis of frozen shoulder (adhesive capsulitis).
History of acute trauma or fracture involving the shoulder girdle (e.g., clavicle fracture, shoulder dislocation).
History of shoulder surgery.
Trial design
Parallel
Treatments tested in this trial
Rigid Taping
Other interventionRigid taping will be applied to the acromioclavicular joint using a standardized technique aiming to posteriorize the acromion and inferiorize the clavicle. Taping will be performed once weekly for 4
Exercise Program
Other interventionA standardized shoulder exercise program focusing on soft tissue flexibility, scapular stabilization, and rotator cuff activation will be applied once weekly for 4 weeks.
Treatment groups
Trial outcomes
Primary outcomes
Pain Intensity
Pain intensity will be assessed at rest and during activity using the Visual Analog Scale (VAS).
Shoulder Range of Motion
Shoulder range of motion (flexion, abduction, internal rotation, and external rotation) will be assessed using a goniometer by recording active range of motion until pain onset, active range of motion despite pain, and passive end-range of motion.
Secondary outcomes
Shoulder Function
Shoulder function will be evaluated using the American Shoulder and Elbow Surgeons Shoulder Score (ASES), which assesses pain and functional activities of daily living.
