Effects of Knowledge of Results Intervention in Rotator Cuff-Related Shoulder Pain
Enrolling by invitation · Not applicable
Conditions studied: Rotator Cuff-related Shoulder Pain, Augmented Feedback, Rehabilitation
In brief
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.
