A: awake felines were placed into a restraint device mounted on a servocontrolled tilt table. The two-axis tilt table was used to provide vestibular stimulation by rotating the animal in the roll plane. B: a servocontrolled motor positioned behind the animal provided hindlimb movement. The hindlimb was placed through a hole in the restraint bag and secured to the servocontrolled motor via a Velcro strap attached immediately proximal to the ankle. Hindlimb position at midline and extension, with relative angles of the knee and hip joints, are shown. [Figure modified and reproduced from Ref. 41 with permission from Springer.]
