|
Define TENS, technically
|
any stimulator that delivers electrical current
|
|
|
what is the most common waveform used for TENS
|
square
|
|
|
T/F: people respond the same regardless of waveform
|
FALSE
|
|
|
What is the frequency most used for gate control therapy for TENS
|
80-120 Hz
|
|
|
Describe the mechanisms of action for gate control theory
|
stimulation of A-beta sensory fibers excite interneurons in the dorsal horn, producing inhibition on nociceptive input from smaller diameter A-delta and C-fibers
|
|
|
Explain the mechanism of action for endogenous opiates
|
stimulates A-beta sensory, A-alpha, A-gamma motor fibers that leads to opiate production, blocking substance P
