Abstract

Objective ambulatory assessment of movements of patients is important for an optimal recovery. In this study an ambulatory system is used for assessing gait parameters in stroke patients. Ultrasound range estimates are fused with inertial sensors using an extended Kalman filter to estimate 3D positions, velocities and orientations. For eight stroke patients step lengths and swing and stance times are calculated from a ten meter walk trial and compared to the Berg balance scale. First results show a correlation between step lengths and Berg balance scale score. However, more patients are to be measured and different activities will be investigated in the coming months.
