Analysis and Suppression of Tremor During Grasp Using Ultrasound Imaging and Electrical Stimulation

We will collect ultrasound images during the grasping motion for both groups

We will collect electromyography (EMG) signals of both the flexor and extensor muscles of the wrist during the grasping motion for both groups

We will use data from the ultrasound images and EMG to develop a tremor model. The model will be validated in comparison to joint angle measurements from an Inertial Measurement Unit (IMU) collected during the grasping motion

We will use the develop closed-loop control methods for tremor suppression using information from the ultrasound-image based tremor models. FES will be used to provide stimulation that will help with tremor suppression
