Key points
- Postural control comprises two distinct levels: 'posture' (tonic muscle activity) and 'equilibrium' (perturbation compensation).
- These two levels, though related, possess separate neuromuscular bases.
- Muscle tone disturbances can affect overall movement performance.
- Skeletal muscle properties are important peripheral factors in postural regulation.

Abstract
From ancient Greece to nowadays, research on posture control was guided and shaped by many concepts. Equilibrium control is often considered part of postural control. However, two different levels have become increasingly apparent in the postural control system, one level sets a distribution of tonic muscle activity ("posture") and the other is assigned to compensate for internal or external perturbations ("equilibrium"). While the two levels are inherently interrelated, both neurophysiological and functional considerations point toward distinct neuromuscular underpinnings. Disturbances of muscle tone may in turn affect movement performance. The unique structure, specialization and properties of skeletal muscles should also be taken into account for understanding important peripheral contributors to postural regulation. Here, we will consider the neuromechanical basis of habitual posture and various concepts that were rather influential in many experimental studies and mathematical models of human posture control.
