The goal is create a device that will help in hand rehabilitation in the first few months after stroke. Stroke is the leading cause of long-term disability in the United States. Hand impairment is prevalent in stroke patients and is particularly debilitating since it limits independence and the ability to use the hand to do real tasks like eating and drinking.
The device must be easy to attach to the impaired arm, comfortable to wear and flexible to accommodate various sized hands and forearms. It also must be able to attach to either the left or the right arm. The entire device must be portable and mobile so that it can be used while the patient is seated in a wheelchair. The device will use functional electrical stimulation via an existing TENS unit, FES, and electromagnets to assist in grasp and release of an object. The pronation and supination of the wrist are the motions in which we will focus.

We’ve constructed a wooden prototype and prepared our presentation and written report for the end of the semester. For future work we plan to build a prototype out of lighter and non pourous materials like plastic and implement a motor controlled by a microcontroller to allow for customization of the rehabilitation program.
