Tarsal Tunnel Syndrome
24 Tarsal Tunnel Syndrome Patients with pain and numbness in the foot often are referred to the electromyography (EMG) laboratory for evaluation of possible tarsal tunnel syndrome (TTS). TTS results…
Amyotrophic Lateral Sclerosis and its Variants
27 Amyotrophic Lateral Sclerosis and its Variants Electrodiagnostic (EDX) studies play a central role in the evaluation of patients with amyotrophic lateral sclerosis (ALS), the most common of all motor…
Late Responses
4 Late Responses Nerve conduction studies are most often used to assess distal nerve segments, with routine stimulation seldom done above the elbow or knee. Few studies can be easily…
Repetitive Nerve Stimulation
6 Repetitive Nerve Stimulation The use of repetitive nerve stimulation (RNS) dates back to the late 1800s, when Jolly made visual observations of muscle movement that occurred after nerve stimulation….
Anomalous Innervations
7 Anomalous Innervations Although peripheral nerve anatomy is more or less similar among individuals, in a sizable minority, there are some significant anatomic variations. These are known as anomalous innervations….
Approach to Electrodiagnostic Studies in the Intensive Care Unit
37 Approach to Electrodiagnostic Studies in the Intensive Care Unit The majority of electrodiagnostic (EDX) studies are performed on outpatients, even in those electromyography (EMG) laboratories that are physically located…

Basic Overview of Electromyography
12 Basic Overview of Electromyography After the nerve conduction studies are completed, the electrophysiologic evaluation moves on to the needle electromyography (EMG) examination. Like the nerve conduction studies, each needle…
