We investigated the changes in muscle fiber conduction velocity, recruitment and derecruitment thresholds, and discharge rate of low-threshold motor units during a series of ramp contractions. The aim was to compare the adjustments in motor unit activity relative to the duration that each motor unit was active during the task. Multichannel surface electromyographic (EMG) signals were recorded f...

introduction: arteriovenous fistulas (avf) make chronic hemodialysis easy, but the complications are unpredictable. ischemic neuropathy due to arterial insufficiency is one of the most important complications of avf. this study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. methods: in this cross-sectional study, 37 hemodialysis p...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...

BACKGROUND The severity of neuromuscular symptoms and signs in hypothyroidism is known to be related to the duration and degree of hormone deficiency. PURPOSE The present study was aimed to assess whether recently diagnosed and untreated hypothyroidism affects peripheral nervous system. METHODS The study included a total of 120 female subjects with age ranging from 20 to 45 years. The motor...

Although measurements of nerve conduction velocity in man were first made nearly a hundred years ago, the procedure was not used clinically until 1948 when Hodes, Larrabee, and German reported reduced conduction velocity in regenerating motor nerves. Later, Hodes (1949) described slow conduction in surviving nerve fibres after poliomyelitis, and more recently it has been shown that conduction m...
