We evaluated the repair of sectioned rat sciatic nerve by the comparison of electrophysiologic parameters. The repair was effected with suture (group A), fibrin glue (group B) or a combination of both techniques (group C). The amplitude, latency and conduction velocity of the motor and nerve action potentials were assessed before the nerve section and at reoperation after 24 weeks. There was no...

In acute idiopathic polyneuritis weakness of relatively sudden onset sometimes progresses swiftly to severe paralysis. And yet even severely affected patients with this disease may survive with the aid of artificial respiration and apparently recover complete motor and sensory function within several weeks. The nature of the disturbance of nerve conduction underlying this reversible loss of fun...

The aim of this study was to analyze the effect of ischemia on low-threshold motor unit conduction velocity. Nine subjects were trained to isolate the activity of a single motor unit (target motor unit) in the abductor pollicis brevis muscle with feedback on surface EMG signals recorded with a 16-electrode linear array. After training, the subjects activated the target motor unit at approximate...

1. Maximum motor nerve conduction velocities were determined under standard conditions for the median and ulnar nerves in the right forearm in males: (a) from the general population, (b) from a subnormality hospital, and (c) in males with the XYY sex chromosome abnormality. Distal latencies for these nerves were also measured. 2. No significant differences in maximum peripheral motor nerve cond...

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...

AIM To investigate the effectiveness of local steroid injection and surgical decompression in the treatment of patients with severe carpal tunnel syndrome (CTS) and also to compare short-term outcomes using clinical and electrophysiological criteria. MATERIAL AND METHODS The patients diagnosed as severe CTS were divided into two groups. Group 1 received local steroid injection and Group 2 und...
