Effects of Knowledge of Results Intervention in Rotator Cuff-Related Shoulder Pain

Turkey (Türkiye)56 participantsStarted 2026-05-05

Plain-language summary

Previous research demonstrates that augmented feedback effectively enhances motor skills and performance in both healthy individuals and those with neurological conditions. However, while the role of Knowledge of Results (KR)-a specific augmented feedback strategy-in supporting motor learning is well-established, its efficacy in improving rehabilitation outcomes remains unclear. Notably, there is a lack of studies in the current literature investigating the effects of augmented feedback strategies in individuals with rotator cuff-related shoulder pain (RCRSP). Given the complex and multidimensional pain neurophysiology associated with RCRSP, a KR intervention is hypothesized to hold significant potential for restoring motor control, correcting pain-driven maladaptive movement patterns, alleviating pain, and recovering function in this population. Therefore, the primary objective of this study is to investigate the effects of a KR intervention on clinical outcomes, physical performance, and psychosocial parameters in individuals with RCRSP. The study is designed as a two-arm, prospective, parallel-group, randomized controlled trial. Eligible participants meeting the inclusion criteria will be randomly allocated to either the intervention (n = 28; standard rehabilitation program+ KR intervention)or control group (n = 28; standard rehabilitation program) using computer-based randomization software (www.sealedenvelope.com). Both groups will undergo the same routine exercise-based treatment protocol over an 8-week period, consisting of one physiotherapist-supervised session per week and a home exercise program on the remaining days. While the control group will solely receive the standard rehabilitation program, the intervention group will additionally receive the KR intervention, wherein their assessment results will be regularly shared throughout the treatment process. Conversely, these data will only be disclosed to the control group participants at the conclusion of the 8-week intervention.

Inclusion Criteria: * Aged between 18 and 35 years; * Presence of unilateral shoulder pain lasting for at least 3 months; * Confirmed diagnosis of at least one of the following conditions by a physician, based on clinical evaluation and magnetic resonance imaging (MRI) or ultrasonography (USG) findings: subacromial impingement syndrome, subacromial bursitis, rotator cuff tendinopathy, or partial rotator cuff tear (\< 1 cm); * Presence of a positive painful arc during flexion or abduction, at least one positive impingement test (Neer or Hawkins-Kennedy), and provocation of symptoms during resisted humeral external rotation, abduction, or scapular plane elevation at 90° of elevation; * A physical activity score of 5 or higher according to the Tegner Activity Level Scale. Exclusion Criteria: * Presence of bilateral shoulder pain; * Presence of a full-thickness or massive rotator cuff tear; * History of shoulder trauma, fracture, or instability; * Restriction in passive range of motion; * Receipt of any injection to the shoulder joint within the previous 6 weeks; * History of previous shoulder surgery or dislocation; * Pregnancy; * Presence of cervical radiculopathy symptoms or peripheral nerve entrapment syndromes; * A score of 14 or higher on the Beck Depression Inventory-II; * Diagnosis of hypertension, cardiovascular disease, peripheral vascular disease, history of deep vein thrombosis, neurological disorders, systemic inflammation, diabetes, cancer, or rheumatological dis…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
