19.1 Lange medium frequency test
19
The Lange medium frequency test gives a general indication of whether a
muscle is partially or totally denervated. The electrodes are positioned on the
muscle for testing.

Note:
By regulating the intensity the Pulse button becomes active..
Implementation
Trigger a single pulse by setting an appropriate intensity and pressing the
button.
Then the test is repeated on healthy muscle. If the two muscles have
approximately the same excitability to the single pulse, the muscle in
question is innervated.
If there are significant differences in the reaction of the muscles to high
excitation intensities, the muscle in question is partially denervated.
