Comparison of three sensing modalities: IMU, EMG, and US imaging during the No Stimulation and Stimulation On conditions. These preliminary results were obtained from participants with Parkinsonian Tremor. a) IMU measurements provide summated wrist angular velocity, unaffected by stimulation artifacts. b) Stimulation artifacts clearly affect E.M.G. measurements as the signal completely saturates when the stimulation is on. c) Ultrasound measurements of tissue displacements obtained from both wrist flexor and extensor are unaffected by stimulation artifacts.
