The neurologist who does the test listens to these sounds and watches the monitor in order to detect abnormalities. The action potential (size and shape of the wave) that this creates on the oscilloscope provides information about the ability of the muscle to respond when the nerves are stimulated. Each arm has an ulnar nerve. Muscle Nerve. That was my experience. If a patient has large-fiber neuropathy clinically, the EMG may be pursued to determine if there is axonal damage versus demyelinating or progressive disease but may not be needed or useful if the suspicion is for a small fiber neuropathy. So veterans. NCS can determine nerve damage and destruction, and is often performed at the same time as EMG. Ughhcontemplation.

In my case, the more pain showed my body was working good. London ZN, Burke JF, Hazan R, Hastings MM, Callaghan BC. The electrical activity picked up by the electrodes is then displayed on an oscilloscope (a monitor that displays electrical activity in the form of waves). In PFPS, sEMG assesses vastus muscle inhibition or activation and is 70% specific and 84% sensitive, although an activity instability test has higher positive predictive value (100%) suggesting clinical diagnoses are equally or more useful.12 Surface EMG has been examined in patients with myofascial pain compared to normal control subjects, and a new technique showed accuracy to differentiate 60-85% of patients with myofascial pain from control subjects, suggesting there is inherent physiologic change to muscle in a state of pain.13 In contrast, a review article on sEMG activity in musicians, who have a high prevalence of musculoskeletal pain, found that sEMG utility varied, depending on which muscles were studied.14 Therefore, pain is not always associated with increased sEMG activity. The EMG part was the worse for me because I feared pain and the needles that cause the pain. Susan Sindall.

When patients with neck pain have had deep cervical flexor muscle activation through sEMG it was found that analysis could determine less activation in these muscles when flexed and more activation in the superficial muscles, suggesting patients with pain alter their muscle activation, which may be another way to consider the physiology of pain.15 Variation of activation and inactivation may be explained by pain adaptation theories that suggest agonist muscles have reduced activity during pain whereas opposing muscle group activities increase.16,17.
