For weak muscles, begin with electrodes ______ spaced and biofeedback sensitivity_______, to ______ detection.
|
widely
high increase |
|
|
For a single weak muscle, begin with electrodes placed______ for a more _______signal with biofeedback.
|
closely together
precise |
|
|
As a patient's motor recruitment ability improves with biofeedback, the sensitivity should be set ______ .
|
lower
|
|
|
To decrease muscle activity w/ biofeedback, the electrodes should be initially placed ______ with the sensitivity _____.
|
close together
low |
|
|
As a patient improves with muscle relaxation and biofeedback, the sensitivity should be progressed ______.
|
higher
|
|
|
For FES application with shoulder subluxation, the waveform should be_______, modulation _________, electrode placement should be______ and placed on the ________
|
asymmetrical biphasic
interrupted bipolar supraspinatus and post. deltoid |
|
|
FES for shoulder subluxation treatment parameters for:
amplitude= pulse rate= duration= on/off ratio= |
amp= tetanic mm. contraction to pt toleranc
PR= 12-35pps dur= 15-30min 3Xday on/off= 1:3 progress to 12:1 |
|
|
FES for drop foot utilizes a ________wave form, ________ pulse duration, is modulated by a _________, and placed where?
|
asymmetrical biphasic
20-250 µsec foot switch at the peroneal n. near the fibular head or ant. tibialis m. |
|
|
FES for drop foot parameters:
amplitude= pulse rate= stimulation controlled by= |
amp= sufficient for tetanic contraction enough to dec. PF
PR= 30-300pps a pressure sensitive switch that cuts off stimulation during stance phase, hand switch allows therapist to control also; similiar parameters can be used on PF to facilitate push-off |
|
|
What type of IFC frequency should be used to combat accommodation?
|
sweep or variable where one frequency is fixed and the other varies
|
|
|
This form of NMES is characterized by the crossing of two sinusoidal waves having similiar amplitudes, but different carrier frequencies which interfere with one another to produce an amplitude modulated beat frequency.
|
IFC
|
|
|
IFC parameters:
waveform= modulation= electrode placement= treatment param= |
WF= sinusoidal (amplitude-modulated)
mod= continuous for pain;interrupted for muscle ex. EP= bipolar for small area; quadripolar for larger areas Treat. param.= for pain, similiar to high- or low-rate TENS; for muscle ex. similiar to low- or medium freq. ES |
|
|
Type of ES used for muscle strengthening which characterized by medium frequency, burst alternating current?
|
Russian-can also be used to inhibit muscle spasm
|
|
|
Russian ES parameters:
amplitude= pulse rate= pulse duration= ramp= duty cycle= |
amp=tetanic muscle contraction
PR=50-70pps PD=150-200µsec ramp=1-5 sec on pt tolerance duty cycle=1:5 |
