About the study
This study is being done to see how errors lead to improvement. Specifically, we are evaluating the errors stroke participants make during an upper extremity exercise program when reaching for a target using their affected arm. Once we understand the participant's reaching errors, we plan to create a customized reaching exercise according to the individual's specific error tendencies which will lead to better performance on movement ability after training.
