Quantification of Upper Extremity Use and Effects of Feedback in the Home Setting

Feedback Intervention (Participants Post-stroke), Healthy Control

A pilot study, the purpose of which is to use accelerometers to quantify UE use (1 and two hand use) in healthy controls and people post-stroke from which the investigators will develop use-based feedback to improve recovery in the home setting. The objectives of this pilot study are to: i.) determine the feasibility of using accelerometers to quantify amount of UE use in the home setting in healthy individuals and individuals chronic post-stroke, ii.) quantify and compare the unilateral activity of the weaker (paretic) versus stronger (non-paretic) UEs, iii.) quantify and compare amount of UE use in healthy controls to that of people chronic post-stroke (side matched unimanual use for each arm and bilateral use) in the home, and iv.) assess the effect of a few sessions of in-home accelerometer used-based feedback on unilateral and bilateral UE use. v.) assess kinematic, kinetic, and EMG data during UE movements bilaterally and between healthy controls and subjects post-chronic stroke pre and post feedback (for the people after stroke).
