Q

TENS unit is for

A

pain relief
* Stimulates A-beta fibers to carry information to the spinal cord dorsal horn, synapsing with inhibitory interneurons to block transmission of C fiber pain impulses from the periphery to the brain. (Gate Control Theory)

Q

how does PEMF therapy work

A
  • Stimulates Calcium binding to Calmodulin
  • This increases Nitric Oxide production in tissues
  • Nitric Oxide decreases inflammation

Q

when not to use PEMF

A

patients with pacemakers or over
hemangiosarcoma

increase Ca binding to Calmodulin →↑ nitric oxide which decreases inflammation

Q

how does acupunture work

A
  • Stimulation of A-beta and A-delta fibers via needles-
    impulse synapses with inhibitory interneurons in the dorsal
    horn of the spinal cord decreasing C fiber pain input
  • A delta fibers activates endogenous opioid system in CNS
