Optimum rehabilitation of arm function following stroke will likely require a device capable of facilitating natural movements of the limb. Accordingly, the goal of this project is to develop and evaluate the Multi-Axis Cartesian-based Arm Rehabilitation Machine (MACARM) - a new device for the quantitative assessment and rehabilitation of three dimensional arm movements following stroke.  The specific objectives of the study are to: 1) develop a robotic device with the force and positional accuracy required for upper limb rehabilitation, 2) develop software for upper limb rehabilitation, 3) validate technical aspects of the MACARM’s performance, and 4) test the MACARM with human subjects, including stroke survivors.

• Stroke survivors
• at least 6 months post-stroke
• with impairment of upper limb (shoulder and elbow) function.
