Active Control

Group I: Acute Stimulation: Vibration pattern 1-3 and sham controlActive Control2 Interventions

All participants try on several wearable prototypes in our laboratory that provide vibration or sham stimulation to the arm. Sensors or electrodes taped onto the arm and hand will sense muscle activity and record any changes during periods of vibration and periods with vibration turned off.

Group II: Longitudinal Stimulation: Vibration pattern 4Active Control1 Intervention

1) If the patient gets Botox injections in their hand and arm, their arm function will be measured for three months during this standard care. 2) Next, all patients will be given a wearable device to take home. The patient will wear the device while feeling vibrations for 3 hours during the day while awake for two months. During this time and 1 month after this intervention, arm function will be tested.
