ClinConnect Summary

This clinical trial is looking at how two types of treatments—NMES (which uses small electrical pulses to stimulate muscles) and sEMG biofeedback (a method that helps patients see how well their muscles are working)—can help improve shoulder function in people who have had a reverse shoulder replacement (rTSA). The goal is to see if these treatments can help the deltoid muscle and other shoulder muscles work better, which can make it easier for patients to move their shoulders.

To be eligible for the study, participants need to be between 20 and 85 years old, have had a primary reverse shoulder replacement surgery, and should be able to raise their arm above 90 degrees three months after the surgery. However, those who have had other shoulder surgeries, have certain muscle or nerve diseases, or have cognitive issues are not eligible. If someone joins this trial, they can expect to receive these specialized treatments and be monitored to see how their shoulder function improves. This research could help improve recovery options for people after shoulder surgery.
