Two measurement methods of motor ulnar nerve conduction velocity at the elbow: a comparative study.
BACKGROUND Electrodiagnostically, localization of ulnar nerve lesions, which commonly occurs at the elbow, is sometimes problematic. Measurement of motor ulnar nerve conduction velocity (NCV) at the elbow is amongst the most popular techniques to diagnose ulnar neuropathy. In this method, recording from the first dorsal interosseous muscle (FDI) is suggested to be more sensitive than the abduct...
متن کاملMotor nerve conduction velocity in spinal muscular atrophy of childhood.
The ulnar and posterior tibial conduction velocities were measured in 29 children with spinal muscular atrophy, 14 of whom had the servere form of the disease. The ulnar nerve velocity was slow in 12 of the 14 severely affected infants, but normal or fast in 11 of 14 children less severely affected. The corresponding results for the posterior tibial nerve were slow velocities in 11 of 12 infant...
متن کاملRatio of motor nerve conduction velocity to F-wave conduction velocity in diabetic neuropathy.
OBJECTIVE To investigate the usefulness of a new parameter, the ratio of motor nerve conduction velocity to F-wave conduction velocity (M/F ratio), for the differential diagnosis of diabetic neuropathy. RESEARCH DESIGN AND METHODS Nerve conduction studies were conducted in 95 patients with diabetic neuropathy, 44 nondiabetic patients with peripheral neuropathy, and 24 normal control subjects....
متن کاملMotor nerve conduction velocity in very preterm infants.
Sufficient reference values for motor nerve conduction velocity (MNCV) in very preterm infants are not yet available. In the placebo infants within an L-thyroxine supplementation trial, born at less than 30 weeks' gestation, ulnar and posterior tibial MNCV measurements were performed shortly after birth. Repeated measurements were done at 2 weeks, at term, and at 6 months corrected age. Cross-s...
متن کاملMaximum motor nerve conduction velocity in XYY males.
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...
