Q

High Volt: PPS

A

LOW FREQUENCY
3-5 edema
15-25 muscle exercise
> 50 fatigue

PAIN RELIEF
1-20 endorphin production - low & slow
80-150 enkephalin production - high & fast

THESE ARE ALL EMS

Q

High Volt: Mode

A
  1. Continuous Mode
    beneficial for edema, pain and neuritis
  2. Reciprocal Mode
    permits alternating contracture of agonist & antagonist
    limits accommodation
  3. Surge on/off
    used when re-education & exercise is desired
