Postural reactions associated with intentional segmental movements

Anticipatory postural adjustments (APA) associated with intentional movement were studied in relation to dynamic asymmetry, a factor that characterizes the perturbing effect of movement on body equilibrium. Simultaneously, local movements were studied by electromography and accelerometry, and general body movements were investigated by the means of a force plate. The results showed that APA were specific to dynamic asymmetry in healthy subjects: they are preprogrammed, and it can be assumed that they constitute a part of the motor program.<
