Cervical radiculopathy is a common diagnosis with a peak onset in the fifth decade. The most commonly affected nerve root is C7, C6, and C8. The etiology is often compressive, but may arise from noncompressive sources. Patients commonly complain of pain, weakness, numbness, and/or tingling. Examination may reveal sensory or motor disturbance in a dermatomal/myotomal distribution. Neural compres...

The evaluation of patients with suspected polyneuropathy (subsequently referred to as “neuropathy”) is relatively straightforward, and consists of a combination of clinical, electrophysiologic, and laboratory studies. Evaluation of suspected neuropathy is among the most frequent investigations performed in the electromyography (EMG) laboratory. The electrodiagnostic (EDX) examination includes s...

INTRODUCTION We report a rare case of fulminant vasculitic mononeuropathy resulting in brachial diplegia, with suspected brainstem and autonomic nervous system involvement in a patient with diabetes mellitus. CASE PRESENTATION A 58-year-old Hispanic Caucasian man with diabetes mellitus presented with a 1-year history of progressive bilateral upper extremity weakness, orthostatic intolerance a...

UNLABELLED We used a neuroselective transcutaneous electrical stimulus to determine the onset time of cutaneous anesthesia with 4% liposomal lidocaine under occluded and nonoccluded conditions. The pain tolerance threshold (PTT) was used to atraumatically evaluate nociception. Twenty adult volunteers had liposomal lidocaine applied to the volar surface of each forearm for durations ranging from...

STUDY DESIGN Cross-sectional diagnostic accuracy study. OBJECTIVE To investigate the relationship between history and physical examination findings and the outcome of electrodiagnostic testing in patients with sciatica referred to physical therapy. BACKGROUND Electrodiagnostic testing is routinely used to evaluate patients with sciatica. Recent evidence suggests that the presence of radicul...

BACKGROUND Current electrodiagnostic criteria for chronic inflammatory demyelinating polyneuropathy (CIDP) are research oriented favoring specificity over sensitivity. Application of such criteria in clinical practice may miss the diagnosis in potentially treatable patients. OBJECTIVES To analyze the electrophysiologic abnormalities in a cohort of patients with clinically defined CIDP, to com...
