title: Organization of preparatory postural responses for the initiation of lateral body motion during goal directed leg movements.
abstract: Postural responses preceding single leg flexion movements were examined in human subjects with respect to a hypothesized primary role of the hip joint abductor-adductor musculature in initiating lateral body motion during alterations in stance. The results indicated a speed sensitive interlimb response organization compatible with predictions based on a mechanical model. In conjunction with other recent studies, the findings may be indicative of a common organizational substrate for the initiation of laterally directed motion of the body.
