Consecutive postural adjustments (CPAs): A kinetic analysis of variable velocity during a pointing task.

Aim: This paper examines the postural adjustments that occur after the end of a voluntary movement (consecutive postural adjustments, CPAs). Its aim is to reinforce the theory that CPAs are necessary to counterbalance the destabilizing effect of a voluntary movement. In addition, we compared the main features of CPAs with those of anticipatory postural adjustments (APAs) in order to gather evidence that could afford new insights into postural programming.

Are simultaneous postural adjustments (SPA) programmed as a function of pointing velocity?

This paper deals with the influence of velocity on the postural adjustments that occur during the course of a voluntary movement, that is to say, simultaneous postural adjustments (SPA). To this aim, a pointing task performed at different velocities (V) was considered. Upper limb kinematics and body kinetics were recorded.

Simultaneous Postural Adjustments (SPA) scrutinized using the Lissajous method.

The goal of this research was to study the postural adjustments that occur during the course of a voluntary movement (Simultaneous Postural Adjustments: SPA). A pointing task performed at maximal velocity was considered and upper limb kinematics and body kinetics were recorded. A 2-DOF model was elaborated that distinguishes between the body segments that are mobilized in order to perform the pointing movement.

Particular adaptations to potentially slippery surfaces: the effects of friction on consecutive postural adjustments (CPA).

This research deals with the postural adjustments that occur after the end of voluntary movement ("consecutive postural adjustments": CPAs). The influence of a potentially slippery surface on CPA characteristics was considered, with the aim of exploring more deeply the postural component of the task-movement. Seven male adults were asked to perform a single step, as quickly as possible, to their own footprint marked on the ground.

The Consecutive Postural Adjustments (CPAs) that follow foot placement in single stepping.

This research deals with the postural adjustments that occur after the end of a voluntary movement ("Consecutive Postural Adjustments": CPAs). With the aim of more fully characterizing the postural component of motor tasks, they are compared with those occurring before movement onset ("anticipatory postural adjustments": APAs). Ten male adults were asked to perform a single step as quickly as possible to a target marked on the ground (STEP).
