- Reflexes only occur in healthy nerves, their absence indicates a lesion or a lack of function.
- Irritation is caused by sensory bombardment or affarentation
- Virgil Strang
- Subluxation is defined as a biomechanical disrelation or dysfunction any where in the body but particularly in the spine resulting in aberrant neural function

- Somatic dysfunction- current term used in osteopathic school refers to four reflexes
- Somatosomatic
reflex- somato means muscle, ligament tendon and joint. Signal is initiated in asomatic area and travels to the dorsal cord which excites it and causes sclerotomal pain (other somatic tissue that is segmentally related to the lesion site) in the? The signal also then excites the anterior horn and excites the alpha motor neurons and causes muscle spasms in the muscle of that segment.
- Somatosomatic reflexes can continue due to spasms of the muscles and can keep the cycle going even though the injured tissue has healed.
- Somatovisceral
- Occur commonly but don’t occur from nerves being pinched examples include a shoulder problem or injury causing increased heart rate.
- Viscerosomatic
- Occur when viscera refer pain to the periphery such as the shoulder etc.
- Viscerovisceral
- A problem from the viscera can cause problems in other viscera in the body.
- Caillite- said that pain could create a central excitatory state, and so can mechanoreception.
- An excitation of mechanoreceptors can stimulate the sympathetics and create dystrophy due to excessive NE. Release this is also stated by Korrà
trophic disturbance.
- Hyperesthesia- occurs due to excessive release of norepinephrine by the sympathetics because of a central excitatory state.
