Assessment and visualisation of daily-life arm movements after stroke

Abstract

For an optimal guidance of the rehabilitation therapy of stroke patients in an in-home setting, objective, and patient specific assessment of upper extremity task performance is needed. Towards this goal, metrics of hand position relative to the pelvis were estimated and visualized. Metrics, including work area and maximum reaching distance, appeared to strongly correlate with the upper extremity part of the Fugl-Meyer Assessment scale (r>0.84, p<0.001). Proposed metrics and visualisation can be used to objectively assess the arm movement performance over a longer period of time in a daily-life setting, if combined with info about performed task derived from a activity monitor
