We used evoked spinal cord potentials (ESCP) for intraoperative diagnosis in 17 cases of traumatic brachial plexus palsy. Forty spinal nerves were directly stimulated during exploration of the brachial plexus and ESCP recorded from the cervical epidural space were compared with simultaneously observed somatosensory evoked potentials (SEP) and myelographic findings. Both SEP and ESCP could be ev...

Electrodiagnostic procedures have contributed to the certainty of diagnosis of a variety of neurological and neuromuscular diseases in animals. Widespread use of electrodiagnosis is limited by equipment costs and training of personnel. However, many of these procedures are used routinely in case work-ups in veterinary colleges or specialty practices. The purpose of this chapter is to present a ...

PURPOSE OF REVIEW This article provides a clinical approach to peripheral neuropathy based on anatomic localization and diagnostic testing. RECENT FINDINGS Advances have been made in the evaluation of small fiber neuropathy and in the known genetic causes of neuropathy. SUMMARY History and physical examination remain the most useful tools for evaluating peripheral neuropathy. Characterizati...

Needle electromyography (EMG) is used for the diagnosis of a neural injury in patients with a cervical/lumbar radiculopathy, plexopathy, peripheral neuropathy, or myopathy. Needle EMG is a particularly invasive test and thus it is important to minimize the pain during inspections. In this paper, we introduce the Electrodiagnosis Support System (ESS), which is a clinical decision support system ...

Electrodiagnosis, which includes nerve conduction and needle electromyographic studies, is an essential element in the evaluation of peripheral neuropathies. A systematic approach to the electrodiagnostic evaluation aids in clarifying the distribution and extent of involvement, type of nerve damage, and time course. When these data are combined with clinical information, a full characterization...

OBJECTIVE To access the percentage of the patients whose repetitive nerve stimulation (RNS) studies were negative for 10% amplitude decrement but positive for 10% area decrement and to compare these disagreed results with specialist physician's diagnosis. STUDY DESIGN Retrospective descriptive study. SETTING Electrodiagnosis laboratory, Department of Rehabilitation Medicine, King Chulalongk...

Background: Two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (OP) and abductor pollicis brevis (APB). However, Riché-Cannieu communicating branch (RCCB) may limit the use of these muscles in electrodiagnosis. This condition is confusing in the case of median nerve injuries. This study was conducted to evaluate the prevalence of RCCB. &...

Amyotrophic Lateral Sclerosis (ALS) is a fast-progressing disease with no cure. Nowadays, needle electromyography (nEMG) the standard practice for electrodiagnosis of ALS. Surface (sEMG) emerging as more practical and less painful alternative to nEMG but still has analytical technical challenges. The objective this work was study feasibility using set morphological features extracted from sEMG ...
