TENS Flashcards
Pain modulation through activation of central inhibition of pain transmission
Gate theory
Current types
Continuous, pulsatile, burst
Wave forms
Asymmetrical biphasic with zero net direct current
OR pulsed monophasic current
Conventional TENS aka
High rate
Conventional TENS: used for what phase of pain
Acute, chronic
Conventional TENS uses what theory
Gate theory/mechanism
Conventional TENS: Amplitude ? Pulse Rate ? Pulse Duration? Mode ? Tx Duration ? P! Relief Duration ?
Amp: comfortable, paresthesia, no muscle twitch Pulse Rate: 50-80 pps Pulse Duration: 50-100 usec Mode: continuous Duration: 20-60 min P! Relief temporary
Acupuncture-Like TENS aka
Strong low rate
Acupuncture-Like TENS used for what phase?
Chronic
Acupuncture-Like TENS: analgesia produced through stimulation-evoked production of ?
Endogenous opiates
Acupuncture-like TENS: Onset of pain relief?
20-40 min
Acupuncture-like TENS: Amplitude ? Pulse Rate ? Pulse Duration? Mode ? Tx Duration ? P! Relief Duration ?
Amp: strong but comfortable, rhythmic muscle twitches Pulse rate: 1-5 pps Pulse duration: 150-300 usec Mode: continuous Tx duration: 30-40 min P! Relief: long lasting (1+ hrs)
Brief intense TENS: provides ___ onset, ___ -term pain relief during ______
Rapid
Short
Painful procedures (debridement, deep friction massage, jt mob, passive stretch)
Brief intense TENS: Amplitude ? Pulse Rate ? Pulse Duration? Mode ? Tx Duration ? P! Relief Duration ?
Amp: pt’s tolerance Pulse rate: 80-150 pps Pulse duration: 50-250 usec Mode: continuous Tx duration: 15 min P! Relief: temporary (30-60 min)
Burst mode TENS has what characteristics?
Characteristics of both high- and low-rate TENS
Burst-Mode TENS: stimulation of ___, current more ___ than low-rate TENS
Endogenous opiates, tolerable
Burst-mode TENS: Amplitude ? Pulse Rate ? Pulse Duration? Mode ? Tx Duration ? P! Relief Duration ?
Amp: comfortable, intermittent analgesia Pulse rate: 50-100 pps in bursts of 1-4 pps Pulse duration: 50-200 usec Mode: continuous Duration: 20-30 min P! Relief: long-lasting (hours)
Hyperstimulation (point stimulation) TENS: use of small probe to locate ____/____
Noxious stimuli, trigger points
Hyperstinulation TENS Amplitude ? Pulse Rate ? Pulse Duration? Mode ? Tx Duration ? P! Relief Duration ?
Amp: strong, to pt’s tolerance Pulse rate: 1-5 pps Pulse duration: 150-300 usec 15-30 second increments Long-lasting p! Relief
Modulation Mode TENS: altering ___, ____, ___ by __% or more
Frequency, intensity, pulse duration, 10%
Contraindications for TENS
- Over chest of pt with cardiac disease
- Over eyes, laryngeal/pharyngeal muscles, head/neck of pt after CVA or with epilepsy
- Over mucus membranes
