Neurophysiological effects of spinal manipulation

Pickar, J2002

Abstract:

Despite clinical evidence for the benefits of spinal manipulation there is relatively limited evidence for the biological mechanisms underlying its effects. This hinders acceptance by the scientists and health-care professionals.

Purpose:

To examine the neurophysiological basis for the effects of spinal manipulation.

Study design:

A review article discussing primarily basic science literature and clinically oriented basic science studies.

Methods:

Medline peer-reviewed literature and books. A theoretical model is presented describing the relationships between spinal manipulation, segmental biomechanics, the nervous system and end-organ physiology.

Results:

Spinal manipulation changes biomechanics creating physiological consequences via inflow of sensory information to the central nervous system.

Conclusions:

A body of evidence exists indicating that spinal manipulation impacts primary afferent neurons from paraspinal tissues, the motor control system and pain processing.
