|
As close to the muscle being monitored as possible
|
|
What happens if there is a failure to achieve appropriate electrode placement when using electromyographic biofeedback?
|
It can result in inadequate audio or visual activity or an increase in extraneous electrical activity.
|
|
If the surface electrodes are determined to be in an appropriate location, what may then happen when using electromyographic biofeedback?
|
It may then be necessary to increase the sensitivity setting on the biofeedback unit

What is the two-point discrimination used for?
|
It is a testing procedure that quantifies the smallest distance b/w two stimuli where the patient is still able to identify two distinct points. The two points is measured with a ruler

|
Between 5 to 10 degrees
|
|
How is the carrying angle created?
|
By the long axis of the humerus and the long axis of the ulna
