PTAP 1240 EXAM 2 QUIZZES WITH
100% VERIFIED ANS!!

Term
how to determine electrode placement when applying NMES?
Give this one a try later!
Patient positioning
Electrode type and
placement
Waveform and pulse duration
, Frequency and on:off time
Total treatment time
Patient response
1. improved gait
2.↑ ankle dorsiflexion torque
3. ↓ agonist-antagonist co-contraction
4. ↑ probability of returning home
one electrode over motor point (middle of muscle belly)one on the muscle
to be stimulated parallel to direction of muscle fibers
should be at least 2 inches apart
1. area treated
2.pt positioning
3. stimulation parameters
4. electrode placement
5.tx duration
6.response to intervention
Don't know?

what are the 4 possible therapeutic effects of EMG biofeedback?
Give this one a try later!
1. 35-80 pps
2.125-200 us small muscles; 200-350 us for large muscles
3. >10% of MVIC in injured muscle; >50% MVIC in uninjured
4. 6-10 s on: 50-120 s off (1:5) initially. Reduce off time w repeated tx
5.at least 2 s
6.10-20 mins (=10-20 reps), every 2-3 h when awake
Electrode placement: Negative polarity over area of edema. dispersive electrode
over other large flat area.
1. HVPC
2.Negative over area of edema
3.100-120 pps
4. 40-100 us. Usually preset.
5. comfortable sensory / 90% of visual motor threshold
6.tx time: 20-30 mins per session
1. muscle relaxation
by consciously relaxing/inhibiting muscle. ↓ spasms. ↓ accessory muscle
use.
2.improve muscle strength
isometric contractions. incorporated w functional activities
