EMG (Electromyogram) used as a diagnostics tool for identifying neuromuscular diseases, assessing low-back pain, kinesiology, and disorders of motor control. EMG signals are also used as a control signal for prosthetic devices such as prosthetic hands, arms, and lower limbs.
What is Electromyography (EMG)?
Nerves carry signals from the brain to the muscles and Nerves controls the action of the muscles by electrical signals, called impulses, that measures your nerve signalling and muscle response. Specifically, the needle EMG measures the electrical activity of your muscles. The aim of the EMG is to identify and determine the location, source of the problem.
Why is electromyography?
EMG can help your doctor determine the underlying cause of these symptoms. Tingling Numbness Muscle weakness Muscle pain or cramping Paralysis Involuntary muscle twitching (or tics) Muscle disorders, such as muscular dystrophy Radiculopathies Peripheral nerve disorders that affect the nerves outside the spinal cord, such as carpal tunnel syndrome Nerve disorders, such as amyotrophic lateral sclerosis
