Question 1

how does laser work

Answer 1

stimulates mitochondria to make more ATP

LASER: Light Amplification of Stimulated Emission of Radiation

Question 2

laser contraindications

Answer 2

Over neoplasia, pregnant uterus, gonads, cornea, active
bleeding, endocrine glands and active epiphyses

Question 3

TENS unit is for

Answer 3

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)

Question 4

how does PEMF therapy work

Answer 4

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

Question 5

when not to use PEMF

Answer 5

patients with pacemakers or over
hemangiosarcoma

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

Question 6

how does cryoptherapy work

Answer 6

produce vasoconstriction, decrease local blood flow, inflammatory response and edema
* reduce pain
* slows nerve conduction

Question 7

how does therma therapy work

Answer 7

increase blood and lymphatic circulation’
* reduce edema
* release tension/spasm

Question 8

how does acupunture work

Answer 8

• 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
