Electroanalgesia Flashcards
What are other names for High-rate TENS?
Conventional, Sensory level
What is the purpose of high-rate, sensory level TENS?
Pain control using gate control theory
What type of current is sensory-level TENS?
Asymmetrical Biphasic PC
What is the pulse frequency/rate used for high-rate TENS?
100-150 pps
What is the pulse duration used for sensory-level TENS?
50-80 μs
What should pt feel with high-level TENS (amplitude)?
Should feel “robust” tingling
What surge is used for high-rate TENS?
conventional TENS is continuous; no surge
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.
What are some other names for low-rate TENS?
motor-level, Acupuncture-like
What is low-rate TENS used for?
Pain control using the motor-endorphin release theory
What type of current does Motor-level TENS use?
Burst Asymmetrical Biphasic PC
What frequency/rate does low-rate TENS use?
2-10 pps
What pulse duration does Acupuncture-like TENS use?
200-300 μs
What should the pt feel with low-rate TENS (amplitude)?
Should produce visible contraction
What should the surge be set to for motor-level TENS?
no surge; continuous
How long should motor-level TENS be used for?
20-30 minutes every 2 hours
What is burst mode TENS used for?
Pain control using motor-endorphin release theory
What frequency/rate do you use with burst TENS?
Burst has preset pulse frequency of 10 bursts with 100-150 ops w/in burst.
What pulse duration does Burst TENS use?
Generally preset and may have max of 100-300 μs
What is the amplitude of current for Burst TENS?
should produce visible contraction
How long should burst TENS be used for?
20-30 minutes, every 2 hours
What type of current is burst TENS?
Burst Assymetrical Biphasic PC
What is Interferential current used for?
Pain control
How many electrodes does interferential e-stim use?
4 for normal (2 currents/2 channels)
2 for pre-mod (single current/single channel)
What type of current is interferential?
sinusoidal polyphasic AC (type of medium frequency)
What is the carrier frequency for interferential e-stim?
Usually preset at 4000 or 5000 hz to produce a beat freq of 100 hz
Is there a pulse duration for interferential e-stim?
no can’t be set
What is the amplitude of current you should use for interferential e-stim?
should produce visible contraction
