The influence of associated reactions on upper limb performance following stroke

The recovery of movement following a stroke is often affected by increased reflex activity. Associated reactions are one manifestation of this activity. In early studies it is reported that associated reactions, elicited by semi-reflex activity or voluntary movement elsewhere, result in increased muscle tone and movement in the static, hemiparetic upper limb. In the physiotherapeutic treatment of stroke, importance is attached to the influence of reflex behaviour on the control of movement. [Continues.]
