The Effects of Spinal Manipulation on Central Nervous System Activity Measured by Reflexive Calf Muscle Recruitment

Completed · Not applicable

Conditions studied: Subluxation of Joint of Lumbar Spine

In brief

This study investigated the effects of spinal manipulation on central nervous system activity. The presence of postactivation potentiation, an increase in muscular force production following prior muscular contractions, was measured with electromyography and the muscular force production during electrically-induced calf muscle reflexes. It was hypothesized that significantly greater potentiation would be stimulated by a calf muscle contraction with spinal manipulation delivered immediately beforehand than the potentiation arising from the contraction only.
