Mechanical effort predicts the selection of ankle over hip strategies in nonstepping postural responses
Experimental studies have shown that a continuum of ankle and hip strategies is used to
restore posture following an external perturbation. Postural responses can be modeled by …

Central programming of postural movements: adaptation to altered support-surface configurations
FB Horak, LM Nashner - Journal of neurophysiology, 1986 - journals.physiology.org
We studied the extent to which automatic postural actions in standing human subjects are
organized by a limited repertoire of central motor programs. Subjects stood on support …
