Postural control is defined as achievement, maintenance or regulation of balance during any static posture or dynamic activity for the regulation of stability and orientation. The interaction of the individual with the task and the environment develops postural control. Stability refers to maintenance of the centre of mass within the base of support while orientation refers to maintenance of relationship
within the body segments and between body and the environment for the task. These stability and orientation challenges necessitate change in the task and environment, thereby making postural control the most essential pre requisite for most of the tasks. There are two types of postural control strategies: predictive and reactive, which utilize the feed forward and feedback postural control respectively in order to maintain stability during various circumstances. Feed forward postural control refers to the postural adjustments made in response to the anticipation of a voluntary or a self-generated movement that may be destabilizing in while feedback postural control refer to the postural adjustments made in reaction to sensory stimuli from the externally generated perturbation. Furthermore, these strategies may involve either a fixed-support or a change-in-support response depending on the intensity of the perturbation.
