Ultrasound Feedback for Shoulder Pain

(SCAP-M-RUSI Trial)

This trial explores whether real-time ultrasound images can help individuals with shoulder pain better activate two key muscles, the serratus anterior and lower trapezius, compared to standard clinician feedback. The goal is to determine if this training improves shoulder movement and reduces pain during daily activities. Participants will be divided into two groups: one will train with Dynamic Ultrasound Visual Feedback, while the other will receive standard verbal and tactile feedback. Individuals with shoulder pain affecting daily activities, yet still able to raise their arm above shoulder height, might be suitable for this trial. If ultrasound feedback proves effective, it could provide therapists with a new method to help patients manage shoulder pain. As an unphased trial, this study presents a unique opportunity to explore innovative therapy methods that could enhance the recovery experience.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Research has shown that dynamic ultrasound feedback for shoulder pain is generally safe and well-tolerated. Studies on ultrasound-guided shoulder treatments consistently find these methods safe. They improve movement and reduce pain without causing significant side effects. One study found that using ultrasound during shoulder exercises helps retrain patients without negative effects. This suggests that real-time ultrasound images guiding shoulder exercises are safe for participants, with no major safety concerns reported.¹²³⁴⁵

Most treatments for shoulder pain involve physical therapy exercises with verbal and tactile feedback from a therapist. However, researchers are excited about using dynamic ultrasound visual feedback as an innovative approach. This method provides real-time imaging of shoulder movements, allowing patients to see how their muscles and joints are working during exercises. This visual insight can enhance understanding and execution of exercises, potentially improving outcomes more effectively than traditional feedback alone.

Research has shown that ultrasound imaging can significantly improve the accuracy of shoulder treatments, with studies indicating accuracy rates between 90% and 100%. For individuals with shoulder pain, ultrasound guidance has enhanced pain relief and shoulder function, with reports of pain decreasing and shoulder movement improving by over 30%. In this trial, participants will receive either standardized exercise feedback or standardized exercise feedback with dynamic ultrasound feedback. Dynamic ultrasound is particularly useful because it provides live images, offering a convenient and affordable way to understand shoulder mechanics. This feedback helps patients engage key shoulder muscles more effectively, which can improve movement and potentially reduce pain.¹⁶⁷⁸⁹
