BACKGROUND Reports of motor polyneuropathies in young cats are scarce. Further, in-depth electrophysiologic evaluation to confirm a motor polyneuropathy in young cats of various breeds other than 2 Bengal cats is lacking. HYPOTHESIS/OBJECTIVES To confirm a motor polyneuropathy in young cats of various breeds. ANIMALS Five young cats with heterogenous chronic or relapsing episodes of weaknes...

Many of the disabling fea tures of leprosy ~re caused by peripheral nerve impairment involving both sensory and motor modalities. Pathologic changes in an affected nerve are usually seen at a site where the nerve passes over a bone or joint, or where the nerve is superficial. In the arm the most commonly involved nerves, in order of frequency, are the ulnar at the elbow and the median at the wr...

OBJECTIVE To investigate whether "diseased nerves" are more prone to entrapment neuropathy than normal nerves. Nerve conduction studies of human neuropathies have shown that electrophysiological abnormalities are often most prominent at potential sites of nerve entrapment, and entrapments are more common in patients with radiculopathies--a concept designated as "double crush". As entrapment neu...

Diabetes mellitus produces marked abnormalities in motor nerve conduction, but the mechanism is not clear. In the present study we hypothesized that in the streptozotocin (STZ)-induced diabetic rat impaired vasodilator function in arterioles that provide circulation to the region of the sciatic nerve is associated with reduced endoneural blood flow (EBF) and that these defects precede slowing o...

OBJECTIVE To examine the effect of tai chi chuan exercise on peripheral nerve modulation in patients with type 2 diabetes mellitus. DESIGN Parallel group comparative study with a pre- and post- design. SUBJECTS Twenty-eight participants with diabetes mellitus and 32 healthy adult controls from communities in Kaohsiung, Taiwan. METHODS Cheng's tai chi chuan, 3 times a week for 12 weeks. Fa...

AIM To prove the possibility of axillary nerve conduction changes following shoulder subluxation due to hemiplegia, in order to investigate the usefulness of screening nerve conduction studies in patients with hemiplegia for finding peripheral neuropathy. METHODS Forty-four shoulders of twenty-two patients with a first-time stroke having flaccid hemiplegia were tested, 43 +/- 12 days after st...

OBJECTIVES The diagnostic utility and reliability of an easy-to-operate novel handheld nerve conduction tester in carpal tunnel syndrome (CTS) were evaluated. MATERIALS AND METHODS Using the test device, the sensory nerve conductions (SNC) in the median and ulnar nerves were compared with each other in 194 patients with suspected CTS and 95 healthy controls. The test device results were compa...

We examined two sibs with the classic form of Pelizaeus-Merzbacher disease (PMD) and their relatives. Electromyographic-electroneurographic studies and magnetic stimulation of motor pathways were performed. In both patients we found an absence of compound motor action potential (cMAP) after stimulation of the motor cortex and a normal conduction time by stimulating the cervical roots. Despite r...

Background: Our aim was to investigate the motor outcome, effects on the diaphragm muscle, and delimit the regained nerve conduction capacity of the transected phrenic nerve, following its reconstruction to prepare the subjects to electrophrenic respiration. Methods: All one-year-old 12 healthy pigs (German Landrace) weighing 45 to 50 kg were used in the study. Three groups, each of which consi...

Using surface electrodes, sensory nerve action potentials (SAP) have been recorded in the proximal segment (mid-calf to lateral malleolus) and the distal segment (lateral malleolus to toe 5) of the sural nerve and in the median nerve in 79 control subjects. The values obtained for the distal segment of the sural nerve varied widely and in seven apparently normal subjects no SAP could be disting...
