dissociation movement

dis·so·ci·a·tion move·ment

(di-sō'sē-ā'shŭn mūv'mĕnt)
1. Physical movement that characterized by the ability to differentiate among movements of different parts of the body; e.g., rolling segmentally, which entails leading with the head, followed by the shoulders and then the pelvis, instead of "logrolling," in which the body rolls as a single unit.
2. Stabilization of one part of the body or movement of one part in the opposite direction of another (e.g., pelvic trunk as used in ambulation).
