intensity at a rate for max tolerated contraction - tetanic contraction

what should the intensity be for functional e-stim?

intensity at a rate for functional contraction

what should the intensity be for iontophoresis?

<4mA

what is the total dosage for iontophoresis?

40-80 mA * min

what are the 2 e-stim types that require a ramp up/down time?

e-stim for strengthening and re-education wha

what is the ramp up/down time for muscle strengthening & re-education?

as tolerated - 1-5 sec/1-5sec

functional e-stim is times to what?

the gait cycle

what is the on/off time for muscle strengthening?

10 sec on 50 sec off (1:5 ratio)

what is the on/off time for muscle re-education?

10 sec on 30 sec off (1:3 ratio)

what is the treatment time for high rate stim?

PRN up to 24 hours

what is the treatment time for low rate stim?

at least 20 minutes for about 6 hrs of pain relief

what is the treatment time for e-stim for strengthening?

depends on the # of contractions (10-20 reps)

what is the duration of e-stim for re-educaiton?

depends one the # of contractions - but normally more than 10-20 wha

what is the treatment time for functional e-stim?

PRN

what is the treatment time for iontophoresis?

depends on dosage and patient tolerance

what is electrode configuration for muscle strengthening and re-education?

over motor point, parallel to direction of muscle fibers

what is the electrode configuration for function e-stim?

determined by the manufacture and fine tuned by PT wha

what is the electrode configuration for iontophoresis?

drug delivery (active) electrode over area of pathology & return electrode is a few inches away

what is the mechanism of action for high rate stim?

gating of pain & enkephalin wh

what is the mechanism of action for low rate stim?

endorphin release

what is the mechanism of action for muscle strengthening stim?

overload principle

what is the mechanism of action for iontophoresis?

transmission of medication

what is the modulation for high and low rate stim?

can be modulated according to device - sweep (Hz) or scan (mA)

what are examples of e-stim for pain control?

TENS, IFC, Premodulated, High Volt Pulsed Current (HPVC)

what are examples of e-stim for muscle strength and re-education?
