Effect of dual tasking on postural responses to rapid lower limb movement while seated on an exercise ball.

Miles Browning

In April 2014, Researchers investigated mechanisms of postural control with and without a concurrent task. Interestingly they found the cognitive task had little impact on the response of the trunk muscles. This study raises the question whether voluntary pre contraction of the postural muscles is useful if there is a decoupling of voluntary and postural control mechanisms. Further investigation will be important to clarify these results and see whether this holds true for older patients.

Effect of dual tasking on postural responses to rapid lower limb movement while seated on an exercise ball.

Abstract

Postural adjustments are used by the central nervous system to pre-empt and correct perturbations in balance during voluntary body movements. Alteration in these responses is associated with a number of neuromuscular/musculoskeletal conditions. Attention has been identified as important in this system; performing a concurrent cognitive task has…
