1

What is the goal of NMES?

Stimulate alpha motor neurons

2

Why would you do NMES?

Retrain lost muscle function after injury/surgery. Decrease atrophy after immobilization

3

In NMES physiologic contractions are slow or fast twitch fibers recruited first?

Slow

4

What causes inhibition in NMES>?

Golgi

5

What kind of firing is used in physiologic muscle contractions synchrony or asynchronous?

Asynchronous

6

Does NMES causes fatigue?

Not usually because of the order of firing

7

In electrical muscle contractions what muscle fibers are recruited first?

Fast

8

What is the synchrony of firing in electrical muscle stim?

Synchrony (contraction continues until the stim is lost)

9

Is there fatigue seen in electoral stimulated muscle contrition ?

Yes, rapid

10

How does inhibition work with electrical muscle stim?

GTO is activated but overcome

11

What types of currents are used fro NMES?

Russian, biphasic pulsed, interferential

12

What is beps set at for NMES?

50

13

What does TENS enduce?

Electroanalgesia

14

What are the most common waveform for TENS?

Biphasic, symmetrical, square or rectangular

15

For sensory level TENS what is the target?

A-beta fibers

16

What is the treatment time for sensory level TENS?

20-30 min

17

Is there a duty cycle with TENS?

No

18

What fibers are the target for noxious lever TENS?

C fibers

19

TENS is set to patient_____?

Comfort

20

Acupuncture like more targets what?

A beta fibers

21

Motor level TENS in burst mode is used to target what?

Alpha motor
and delta

22

In noxious tens how many miliseconds is required?

10-20

23

What is the limit on machines for nox tens?

250

24

What is the treatment time for nox tens?

30 seconds per point, 8-10 point per session

25

What is the pulse rate for nox tens?

60-150 hz
