Passive Care - High Volt Flashcards
High Volt: Action
Electrochemical (opiate, pain)
Electrokinetic (contraction)
High Volt: Wave Form
Direct Current (DC) Twin Pulsed
High Volt: Indications
Acute and Subacute injuries to reduce edema, analgesia and spasms
Reduce muscle atrophy, cast, disuse, atrophy
High Volt: Contraindications
Over the heart, pacemakers, low back, and abdomen during pregnancy
Note: Decreased sensation is not a contraindication
High Volt: PPS
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
High Volt: Intensity
Decrease patient perception electrochemical (opioids)
Increase patient toleranceelectrokinetic (contraction)
1-500 mA
High Volt: Mode
- Continuous Mode
beneficial for edema, pain and neuritis - Reciprocal Mode
permits alternating contracture of agonist & antagonist
limits accommodation - Surge on/off
used when re-education & exercise is desired
High Volt: Pad Rule
mA / 1 sq “
3” x 4” = 12 mA
4” long x 3” tall
