a.     Describe the type(s) of information that can be obtained from an EMG.

Solution

EMG is electromyography also termed as nerve conduction velocity test

this is a tool for diagnosing neuromuscular diseases like muscular dystrophy, cervical spondylosis, myasthenia gravis and reumatoid arthritis too

the test is performed by inserting needles that are connected to electrodes, into the muscle of choice. The elecrode in turn sends signals to an osciloscope for recording the nerve conductivity when the muscle is contracted or relaxed voulantarily.

EMG results describe the motor unit action potential of the muscle being assessed.

on the rough hand an abnormal graph suggests the prescence of neuromuscular disorder, but a detailed analysis of the electrograph can describe the behavior of motor fibers

It can describe how a prosthesis behaves in a patient

research works continue in using EMG for telerobotics
