NMES, Med freq, Russian, EMS Flashcards
NMES is for what type of muscle (innervated/deinnervated)?
innervated muscle
What type of current does NMES use?
Biphasic PC (pulsed current)
What is the pulse frequency/rate used for NMES muscle strengthening? Muscle reeducation, spasm reduction and edema reduction>
30-85 pps (pulses per second) for strengthening
For everything else, between 35-50 ops
What is the pulse duration for NMES (all types)?
150-200 μs for small muscles, 200-350 for large muscles
For muscle strengthening, what amplitude of NMES stimulation should you use in injured pts? Uninjured?
> 10% MVIC (max voluntary isometric contraction) for injured
>50% MVIC in uninjured
What are the typical on:off time (surge) for NMES?
initially set at 1:5 for injured or weak its but can reduce time with repeated treatments/with stronger pt.
What is the ramp time associated with NMES?
2 seconds
How long should you do muscle strengthening NMES?
10-20 minutes to produce 10-20 reps
How often should you do muscle strengthening NMES?
Every 2-3 hours when awake
For NMES muscle spasm reduction and edema control, what amplitude should you use?
Enough to produce visible contraction
For NMES muscle spasm reduction and edema control, what on:off time (surge) should you use?
1:1 (2-5 seconds on: 2-5 seconds off)
For NMES muscle spasm reduction and edema control, how much ramp should you have?
at least 1 sec
For NMES muscle spasm reduction how long and how many times a day should you treat?
10-30 minutes every 2-3 hours until spasms are reduced
For NMES edema control, how many times a day should you treat?
30 minutes 2 x a day
What is Medium Frequency e-stim used for?
Muscle strengthening
What type of current is Medium frequency?
AC
What is the pulse frequency (rate) for medium frequency e-stim?
1,000-10,000 pps
What is the pulse duration for Medium frequency e-stim?
preset?
What amplitude of stimulation do you use for Medium frequency e-stim?
Stimulate to visible contraction
What on:off time do you use for Medium frequency estim?
no surge, continuous
What is Russian protocol e-stim used for?
Muscle strengthening/spasm reduction
What type of current does Russian protocol use?
Med. frequency Burst AC
What frequency/rate does Russian protocol use?
2,500 pps in 50 bursts/second
What is the pulse duration for Russian Protocol?
Preset on machine
What amplitude current do you use for Russian Protocol?
produce a visible contraction
What is the treatment time for Russian protocol?
if strengthening-10-20 min for 10-20 reps
If spasm-10-30 min for 10-30 reps
What is EMS used for?
Used for direct stimulation of a muscle after peripheral nerve injury (denervated muscle)
What type of current does EMS use?
Interrupted DC
What amplitude do you use with EMS?
Produce maximum contraction with least discomfort
What are the treatment parameters for EMS?
10-20 contractions 1-2 times a day
