Summary

A control and a post-stroke subject with right-side chronic hemiparesis were studied. The post-stroke subject underwent 30 sessions of balance-perturbed training while walking on an instrumented treadmill where the Balance Assessment Robot (BAR™) randomly delivered pushes to pelvis in various directions at various speeds and at various perturbation amplitudes. The investigators assessed kinematics, kinetics, electromiography and spatio-temporal responses to outward-directed perturbations commencing either at foot contact of the left or the right leg.

Interventions

Type	Name	Description
DEVICE	Balance Assessment Robot (BAR™)	The BAR™ has got six degrees of freedom (DOF) that interface to the pelvis of a walking subject. Five DOFs (translation of pelvis in sagittal, lateral and vertical directions; pelvic rotation and pelvic list) are actuated and admittance-controlled, providing transparent haptic interaction with negligible power transfer; the remaining DOF (pelvic tilt) is passive. The BAR™ is capable of delivering perturbations in the directions forward/backward and left/right, but for the purpose of this study only "outward" perturbations in the frontal plane were considered.
