Anticipatory Postural Adjustments and Dynamic Asymmetry of Voluntary Movement

  • S. Bouisset

Anticipatory postural adjustments (APA) associated with intentional movement were studied in relation to dynamic asymmetry of the movement (bilateral movements, or unilateral ones with and without an added inertia), which integrates the effect of movement on the body structure. Three methods were used simultaneously: local movements were studied by means of electromyography and accelerometry, and general body movements were studied using a force platform.

The results show that APA are specific to the dynamic asymmetry in healthy subjects: they are “preprogrammed” and it can be assumed that they constitute a part of the motor program.

The biomechanical finality of APA may be argued on the basis of a simple biomechanical analysis: they tend to create inertial forces which, when the time comes, will counterbalance the disturbance of balance due to the intentional forthcoming movement.

In Parkinsonian patients, APA no longer exist and the movement velocity decreases.
