Ensemble-averaged (n=10) sagittal-plane mean joint angles (degrees) of the trunk, pelvis, hip, thigh, knee, and ankle recorded during sit-to-stand transfers with clinician-assisted (CA, solid line), device-assisted with no patient effort (D-NE, dotted line), device-assisted with patient's best effort (D-BE, dash-dotted line), and device-assisted with verbal and physical guidance from the clinician (D-CA, dashed line) conditions.
