TYPES of E-STIM

Question 1

NMES Goals

Answer 1

-Atrophy treatment/prevention
-Strengthening
-Synchronous firing of motor units

Question 2

Burst modulation (Russian) NMES is what kind of e-stim

Answer 2

alternating current, interrupted and delivered in short bursts (medium frequency burst alternating current)

Question 3

What is a contraindication of functional electrical stimulation?

Answer 3

non-intact peripheral nerve

Question 4

Common uses of FES?

Answer 4

Shoulder subluxation and foot drop

Question 5

Constructive interference

Answer 5

when two waves are in phase, the sum of the superimposed wave is large

Question 6

Destructive interference

Answer 6

sum of two waves = 0 when waves are 180º out of phase

Question 7

Beat frequency:

Answer 7

resultant frequency produced by two frequencies going into and out of phase.

Question 8

What form of e-stim uses quadripolar set up?

Answer 8

interferential current

Question 9

Why is interferential current so beneficial for pain modulation?

Answer 9

It uses a medium frequency to penetrate skin with less resistance - but the interference mimics low-frequency e-stim that provides increased pain modulation

Question 10

Conventional (high rate) TENS provide pain modulation by

Answer 10

the gate control theory
