Appropriate spinal levels Paraspinal msucle spasms Rib restrictions
52
Threshold potential (spinal facilitation)
The maintenance of a pool of neurons in a state of partial or subthreshold excitation -in this state, less afferent stimulation is required to trigger the discharge of impulses
53
Contributions to pain facilitation
``` Nociception Neuropathic Affective Cognitive Behavioral Opoid tolerance ```
54
Spinal facilitation
May be due to sustained increase in afferent input, aberrant patterns of afferent input, or changes within the affected neurons themselves or their environment

Louisa burns
Look at rabbits and induced SD weekly at tales, C6 and T3 Measured pulse, response to exercise, EKG, and tissue sample See cardiac changes with vertebral lesion
65
T3 lesion functional change
Immediate-rapid weak and somewhat irregular pulse 10 min -slightly stronger, slower and more regulat...but did not return to normal as long as SD persisted 2 months-gradually weaker with staccato quality (ticking)..similar to that found in elderly -not present in rabies without T3 SD
66
Atlas lesion SD induction
Immediate-stronger and irregular pulse 10 min-closer to normal as long as SD persisted 2 months-developed arrhythmias -result of vagus nerve facilitation
67

Take home points
Through reflex interaction the ANS and the MSK system reflect each other Osteopathic practices and principles can help in both diagnosing and treating these reflex interactions The ANS is influenced by out psychological state and this also influences the MSK system and our viscera
