7/19 REVIEW Flashcards
pt needs NMES for strength following TKA
biphasic 10 usec, 50 pps
an appropriate freq. for IFC to treat pain in 70 pps
true
for ionto what’s true about polarity
monopolar - monophasic - direct current
T/F: same amount of current delivered to electrodes of different size
true
DC thermal estim application, which is most likely under cathose
sclerotyic changes
what polarity of drug is lidocaine?
positive
- dexamethasome: negative
what is polarity of drug ionophoresis drug dexamethsome
negative
correct statement about electrical charge
charge is either positive or negative
what 2 waveforms are most appropriate for muscle strengthening
russian
pulsed biphasic wave (NMES)
russian stim also described as
pulsed AC
most cited analgesic of IFC is gate control theory
TRUE
which pain theory do we think is assisting in relief w conventional (HIGH RATE) tens
gate control theory
example of continuous alternating current is
IFC
term is synonymous w PPS
frequency
synonym to amplitude
intensity
generally okay to do estim on pacemaker
FALE
what level of intensity
motor level
NMES for strengthening
10/50/10
what are the paramaters for Russian stim
pulsed AC
200 microsecs
50 pps
contra for estim
carotid bodies - causes stroke
current activating denervted mm is
DC
Y on the graph =
frequency
primary reason to alter IFC w sweep or scan is
avoid accommodation to the stimulus
freq is inversely related to pulse duration
TRUE - one goes up, the other goes down
synonymous to high rate tens
conventional tens
motor- low rate
