Chiropractic Spinal Manipulation Shortens the Cortical Silent Period

Spinal manipulation has been well-documented to decrease pain and improve the functional abilities related to many musculoskeletal disorders through a multi-layer mechanism of action. Several published studies have examined the effects of altered afferent input due to spinal joint dysfunction. This study from JEK has taken that research one step farther and examines the sensorimotor effects of spinal manipulation. The results indicate a shortening of the TMS-induced cortical silent period and an increase in I-wave amplitude after spinal manipulation; which can result in increased strength. The potential clinical implications of this research are astounding. Strengthening is a critical component of everything from rehabilitation to sport-specific performance enhancement. Applying this knowledge through a combination of passive and active care has helped our office achieve fantastic results for our patients suffering from musculoskeletal issues.
