In general, depending on clinical symptomatology, emphasis is focused on EMG to diagnose radiculopathy, plexopathy and myopathy, or on a peripheral nerve conduction study to diagnose peripheral neuropathy. Musculoskeletal pain (MSP), defined as local pain and tenderness in the soft tissues, spine, and joints, is a common symptom that brings patients to EMG laboratory for evaluation.
It is usually performed in conjunction with peripheral nerve conduction studies to diagnose entrapment neuropathies or polyneuropathies.
Needle electromyography (EMG) is a well-established procedure used frequently to diagnose conditions presenting with pain and various sensory symptoms in the spine and extremities and to explain the etiology of focal or diffuse muscle weakness.
