Students from the UW Biomedical Engineering program created an updated biofeedback system to replace the current system. The system utilizes EMG hardware that has already been FDA approved paired with updated software created by the students. The device is still in the testing phase, but early consultation with the user population is necessary for assessing needs and developing requirements. Users also are critical for analytical work and testing throughout product development. The investigators plan to eventually market the software and field testing and feedback to manufacturers are highly desirable.
