Sometimes people will ask "what does it do".
Here's a list of some effects which have been observed during neuroscience research (courtesy of Matthew Long CDI)
- Engages mechanoreceptors to open mechanically gated ion channels and initiate a current flow into the largest and fastest primary afferent neurons.
- Uses a rapid lengthening of muscle to activate the dynamic components of the muscle spindle receptor to fire 1A afferents at a high frequency in order to modulate central neurology (greater than 200 Hz).
- Alters the gain on the muscle spindle system to change muscle tone via the action of gamma motor neurons that innervate the intrafusal muscle fibres.
- Produces a ‘novel’ blend of sensory input that alters the state of the dorsal horn and shapes the responsiveness of spinal cord neurons to future inputs.
- Induces plastic changes in neural circuits via long-term potentiation and depression, depending upon the type of circuit i.e. manipulation can produce long-term depression of the projection neurons of the pain pathways.
- Alters the genetic responses in spinal cord neurons and those in the higher centres.
- Produces a propagated response in neurons in the ipsilateral cerebellum.
- Alters the frequency of firing of lower motor neurons to produce a change in muscle tone, joint stability, position and motion.
