Muscle Contributions to Joint Rotational Stiffness following Sudden Trunk Flexion and Extension Perturbations
Figure 1
An illustration of the experimental device in a sagittal (a) and a coronal view (b). Subjects knelt on the robotic platform and legs (below the pelvis) were secured to framing that was attached to the platform. Subjects wore modified shoulder pads and maintained an upright neutral trunk posture with both arms crossed in front of the chest.
