Shoulder monitoring and treatment system

A shoulder monitoring system for monitoring a patient after tendon repair when shoulder muscle contraction is contraindicated, the system comprising:

• a patch having a front side and a back side, the patch sized and shaped to be positioned on skin of a shoulder region of the patient;
• an electromyogram (EMG) sensor on the patch, the EMG sensor configured to measure activity of a muscle of the shoulder region relative to a predetermined threshold associated with function of the shoulder region;
• a communication component on the patch, the communication component configured to communicate a second electrical signal to and from the system, wherein the second electrical signal provides data as to the muscle activity exceeding the predetermined threshold;
• a feedback unit configured to provide feedback to the patient when the muscle activity exceeds the predetermined threshold, wherein the predetermined threshold is selected to provide feedback to the patient that the contraindicated shoulder muscle contraction is occurring;
• an attachment element configured to secure at least a portion of the back side of the patch to the skin of the patient;
• and
• an opening on the patch that provides a visual line of sight through the patch when the patch is positioned on the patient's shoulder, wherein the attachment element is further configured to secure the opening to align with a surgical landmark of the patient, and wherein the patch further includes one or more alignment markers on the front side of the patch configured to align the opening on the patch to the surgical landmark such that the EMG sensor is positioned in a predetermined position to measure the muscle activity.
