The Effects of Spinal Manipulative Therapy on Postactivation Potentiation
In Brief
A clinical study evaluating Spinal Manipulation, Max Voluntary Isometric Contraction, and 1 other intervention for Subluxation of Joint of Lumbar Spine. Completed, enrolled 20 participants across 1 site.
Detailed Summary
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.
