Answer 1

TENS unit

Question 2

How else can a conventional TENS be known as?

Answer 2

High-Rate TENS

Question 3

When is a TENS effective?

Answer 3

Only while stimulation is applied

Question 4

What parameters are used for conventional TENS?

Answer 4

Pulse duration: 50-80 us (A-beta sensory nerves)
Frequency: 100-150pps
Intensity: Comfortable sensation only
Other: Modulation to limit adaptation

Question 5

How does low-rate TENS work?

Answer 5

Repetitive stimulation of motor nerves (produces brief contractions)

Answer 8

Long-duration Pulse: 100-300us (A-delta nociceptive)
Low Frequency: 2-10pps
Intensity: Amplitude to produce small muscle contraction

Question 9

What is burst mode Tens

Answer 9

Same mechanism as low-rate TENS (may be better tolerated)
