Electric Stimulation 2 Flashcards
Three rationales used to justify estim for muscle strengthening
- Better overall recruitment of muscle
- more selective recruitment of type two faster
- Creates asynchronous contraction between all muscle fibers, creates more demanding stimulus than asynchronous contraction with traditional exercise
For muscle strengthening should the patients be passive or active
Active
better for a wound to be moist or dry for wound healing
Moist
Rationale for wound healing with e-stim
- Polarity from stim will mobilize cells that are required for the inflammatory and proliferation phase of healing
- Artificially put back electrical potential which may be lacking
What type of water used for wound healing
sterile, saline water
When would you use monophasic current (2)
Wound healing or electroosmosis
What is the gate theory of pain (2)
- A fiber’s relay information to substantiata gelatinosa
2. When SG is activated it creates a presynaptic inhibition around T cells, which modulates pain (c fibers)
How do you activate substantiality Gelatinosa?
Get more nonpainful input coming in then painful input
Traction, mobilizations, TENS
Rationale for using estim during electroosmosis
Mobilize edema
Put negative electrons on the Edema your repelling it positive away retracts the edema
People most often use TENS for what purpose
Pain relief
what is the theory of endogenous opiates
Low-frequency TENS theory
Anything that triggers the release of natural endorphins besides drugs
Releases opiates and alters pain sensations stimuli
What is iontophoresis?
Introduction of ions and individual components of topical agents with direct current
How to calculate dosage for iontophoresis?
How long should a typical treatment time be?
How many milliamps?
Dosage equals intensity times treatment time
1 hour
1 miliamp
What charges should be currents and topical agents in order to push into skin
Like charges so they repel
Acidic under positive, basic under negative
Muscle strengthening
Pulse intensity, frequency, width
Strong motor
tetanic (50 pulses per second)
widest (500 µs)
