The purpose of this study was to determine the sensitivity and specificity for the current perception threshold (CPT) test during clinical examination of idiopathic carpal tunnel syndrome (CTS). We studied 71 patients (102 hands) with CTS; 50 healthy individuals (100 hands) served as a control group. Using a neurometer, we investigated standard CPT values(More)
We investigated risk factors for osteonecrosis of the femoral head (ONF) in renal transplant recipients, who are susceptible to the disease. Among 287 renal transplant recipients, 18 ONF patients with enough data were included, and 18 age- and sex-matched recipients without ONF were nominated as reference cases. Risk factors were analyzed using a(More)
The objective of this study was to confirm electrophysiologically both the presence and course of uraemic neuropathy in haemodialysis patients. Nerve conduction studies of the lower extremities were done in 70 haemodialysis patients and 20 normal volunteers. Compared with that in normal volunteers, the distal motor latency in the tibial nerve of patients(More)
OBJECTIVE To relate clinical severity of idiopathic carpal tunnel syndrome (CTS) to current perception threshold (CPT). METHODS Subjects were 51 patients with CTS (involving 51 hands), and 50 healthy control subjects (50 hands). Involved hands were grouped into three clinical grades (mild, moderate, severe). Using a neurometer (Neurotron, Baltimore, MD),(More)
Transcutaneous electrical stimulation applied to the vertebral column produces compound muscle action potentials (CMAPs) from the leg muscles. Using this method, we evaluated the efferent pathways of the lumbosacral nerve roots. The subjects were 26 healthy volunteers and 31 patients with lumbar disc herniation (LDH). CMAP recordings were obtained from the(More)
STUDY DESIGN Patients with lumbar disc herniation were studied with lumbosacral evoked potentials (EPs). OBJECTIVES To evaluate lumbosacral EPs for the functional diagnosis of nerve root lesions in patients with lumbar disc herniation. SUMMARY OF BACKGROUND DATA No clinical studies have been conducted using lumbosacral EPs elicited by body surface(More)
Most vertebral haemangiomas are asymptomatic. A case of spinal reconstruction for symptomatic extraosseous thoracic haemangioma using a titanium cage is reported. Radiographs of the T11 vertebra demonstrated characteristic vertical striations. Magnetic resonance imaging and computed tomography showed spinal cord compression by extraosseous tumour extension.(More)
We evaluated the function of the descending spinal cord motor tracts in patients, with and without spinal cord lesion, using motor evoked potentials. We studied 50 normal volunteers and 15 patients with thoracic lesions. The onset latency of the negative waves of motor evoked potentials for the thoracic spines was obtained, and the descending spinal cord(More)
The objective of the present study was to determine the in situ strain and stress of nerve conduction blocking in the brachial plexus. The measurement of the in situ tension stress inducing functional failure of the brachial plexus consisted of two steps. Step I (in vivo): The brachial plexus of the rabbit was stretched laterally until electrophysiological(More)
