Recovery after ACL injury is difficult to quantify, leaving patients and clinicians to rely on subjective assessments that can mask strength imbalances and delay progress. While technologies to measure muscle activation exist, they are often bulky, expensive, and inaccessible to everyday users outside of clinical settings. There is a need for a system that provides clear, quantitative feedback on muscle performance in a compact, accessible form to support informed rehabilitation, improve outcomes, and restore confidence in movement.
I was responsible for designing the primary display and PCB housings, incorporating key features such as charging functionality with an LED indicator, user control buttons, press-fit slots for EMG sensor nodes, and integrated ventilation to support reliable operation. I also collaborated with an Industrial Designer to refine the wearable bands, ensuring they provided a secure, comfortable fit while supporting consistent sensor placement and overall usability.
