NMES TENS Flashcards
What is the goal of NMES?
Stimulate alpha motor neurons
Why would you do NMES?
Retrain lost muscle function after injury/surgery. Decrease atrophy after immobilization
In NMES physiologic contractions are slow or fast twitch fibers recruited first?
Slow
What causes inhibition in NMES>?
Golgi
What kind of firing is used in physiologic muscle contractions synchrony or asynchronous?
Asynchronous
Does NMES causes fatigue?
Not usually because of the order of firing
In electrical muscle contractions what muscle fibers are recruited first?
Fast
What is the synchrony of firing in electrical muscle stim?
Synchrony (contraction continues until the stim is lost)
Is there fatigue seen in electoral stimulated muscle contrition ?
Yes, rapid
How does inhibition work with electrical muscle stim?
GTO is activated but overcome
What types of currents are used fro NMES?
Russian, biphasic pulsed, interferential
What is beps set at for NMES?
50
What does TENS enduce?
Electroanalgesia
What are the most common waveform for TENS?
Biphasic, symmetrical, square or rectangular
For sensory level TENS what is the target?
A-beta fibers
What is the treatment time for sensory level TENS?
20-30 min
Is there a duty cycle with TENS?
No
What fibers are the target for noxious lever TENS?
C fibers
TENS is set to patient_____?
Comfort
Acupuncture like more targets what?
A beta fibers
Motor level TENS in burst mode is used to target what?
Alpha motor
and delta
In noxious tens how many miliseconds is required?
10-20
What is the limit on machines for nox tens?
250
What is the treatment time for nox tens?
30 seconds per point, 8-10 point per session
