Overview
Brief Summary
The purpose of this study is to determine the effectiveness of training hand movement using FINGER robot after stroke. FINGER is a robot that measures finger movements and allows users to play computer games using those movements.
Detailed Description
Robotic devices can be used to retrain movement after stroke. However, it is unclear how best to assist in movement. Providing physical assistance may improve the flow of proprioceptive information to the nervous system, which may help a person relearn to move a limb. On the other hand, assisting movement with a robot may cause a person to "slack", not trying as hard during therapy. This study will test the effect of different levels of assistance on recovery of finger function during robot-assisted therapy after stroke.

Outcomes
Primary Outcomes
Motor and Strength Outcome Measure Using Box and Block Test Measured in Units of Blocks Placed
Time Frame: From baseline to 1-month post therapy
The primary endpoint was the change in Box and Blocks score, which measures how many blocks a subject can pick up and place in a box in 60 seconds, from baseline to 1-month post-therapy. The higher the scores, the better arm and hand function indicated.
Secondary Outcomes
- Motor and Strength Measure Using Action Research Arm Test Measured as a Score(From baseline to 1-month post therapy)
- Motor, Strength and Sensory Using Fugl-Meyer Test Measured as a Score(From baseline to 1-month post therapy)
