A
  • Re-Education
  • Inhibition
  • Relaxation/Anxiety
17

Q

The _____ theory supports conventional, high rate Tens, as a treatment strategy. The pulse frequency is set to _____ to produce a _____ sensation in the pt. The relief of pain is “immiediate/delayed by 4 hours” and the treatment can be administered for up to _____ hours/day.
