1

What are other names for High-rate TENS?

Conventional, Sensory level

2

What is the purpose of high-rate, sensory level TENS?

Pain control using gate control theory

3

What type of current is sensory-level TENS?

Asymmetrical Biphasic PC

4

What is the pulse frequency/rate used for high-rate TENS?

100-150 pps

5

What is the pulse duration used for sensory-level TENS?

50-80 μs

6

What should pt feel with high-level TENS (amplitude)?

Should feel "robust" tingling

7

What surge is used for high-rate TENS?

conventional TENS is continuous; no surge

8

How long should high-rate TENS be used for?

can be worn 24/7. Effect will stop when taken off. May get sensitized to the stimulation after a while though.

9

What are some other names for low-rate TENS?

motor-level, Acupuncture-like

10

What is low-rate TENS used for?

Pain control using the motor-endorphin release theory

11

What type of current does Motor-level TENS use?

Burst Asymmetrical Biphasic PC

12

What frequency/rate does low-rate TENS use?

2-10 pps

13

What pulse duration does Acupuncture-like TENS use?

200-300 μs

14

What should the pt feel with low-rate TENS (amplitude)?

Should produce visible contraction

15

What should the surge be set to for motor-level TENS?

no surge; continuous

16

How long should motor-level TENS be used for?

20-30 minutes every 2 hours

17

What is burst mode TENS used for?

Pain control using motor-endorphin release theory

18

What frequency/rate do you use with burst TENS?

Burst has preset pulse frequency of 10 bursts with 100-150 ops w/in burst.

19

What pulse duration does Burst TENS use?

Generally preset and may have max of 100-300 μs

20

What is the amplitude of current for Burst TENS?

should produce visible contraction

21

How long should burst TENS be used for?

20-30 minutes, every 2 hours

22

What type of current is burst TENS?

Burst Assymetrical Biphasic PC

23

What is Interferential current used for?

Pain control

24

How many electrodes does interferential e-stim use?

4 for normal (2 currents/2 channels)
2 for pre-mod (single current/single channel)

25

What type of current is interferential?

sinusoidal polyphasic AC (type of medium frequency)

26

What is the carrier frequency for interferential e-stim?

Usually preset at 4000 or 5000 hz to produce a beat freq of 100 hz

27

Is there a pulse duration for interferential e-stim?

no can't be set

28

What is the amplitude of current you should use for interferential e-stim?

should produce visible contraction
