1
Q
RMS stands for
A
root mean squared
2
Q
raw data shows a
A
+ and - defelction
3
Q
RMS functions to
A
clean up the data
makes looking at a maximal contraction easier
4
Q
the RMS does what to the signal?
A
averages
^2 making it positive
square roots making it smaller
5
Q
In the second part of the experiment what was stimulated and where was the recording happening?
A
stimulating- median nerve
recording- at the thumb muscles
6
Q
define latency
A
from 0 to the start of the action potential
7
Q
a higher latency indicates
A
an action potential
8
Q
a lower latency indicates
A
a stimulus artifact
