electrical stimulation terminology Flashcards
Electricity =
flow of electrons
Electricity requires
source of electrons, driving force, path
capacitance
the ability of a material to store charge
current flow in one direction
monophasic current
monophasic current is AKA
galvanic current
time it takes the current to leave the isoelectric line to when it returns to this line
phase duration
two phase durations for each pulse
biphasic
intensity or magnitude of the current
amplitude
maximum amplitude of the current regardless of duration
peak current
amount of current supplied over a period of time
average current
minimum amplitude needed to depolorize a nerve fiber when phase duration is infinite
rheobase
the time required to depolorize a nerve fiber when the peak current is twice rheobase
chronaxie
number of pulses or cycles generated per second
frequency
low frequency generators up to ____Hz
1000
medium frequence generators ___-____Hz
1,000-100,000 Hz
