Directional virtual time-to-contact: A new measure for investigating temporal, spatial, and control aspects of postural balance control

Introduction to a Twin Dual-Axis Robotic Platform for Studies of Lower Limb Biomechanics

“…It also demonstrated the ability to improve paretic ankle control in patients with stroke [7]. However, this device itself was limited to measurements of one-side (right leg) ankle impedance [15] or postural balance studies where both feet were placed sideby-side on the single platform [27], [28].…”
