EMG Flashcards
1
Q
EMG
A
the study of neuromuscular activation of muscled during postural, functional, training, and work conditions
2
Q
Influences EMG signal
A
MU recruitment
MU firing frequency
3
Q
full wave rectification
A
-flip negative to positive
-raw has mean value of 0
-FWR now has all positive, thus can measure peaks and averages
4
Q
averaged EMG
A
-moving averages of the FWR EMG signal
-a time-windowed mean of the absolute value of the signal
-good for determining levels
5
Q
Integrated EMG
A
-area under the curve of the FWR signal
6
Q
normalization
A
-maximum voluntary contraction
-average EMG values of a cyclical motion
-Standard level of resistance
-50% of 1RM EMG signal
-baseline
