• The bilateral median motor action potential has normal distal late cues, amplitudes, conduction, and F wave latencies. (fibromyalgiaforums.org)
  • The bilateral mid palmar median sensory and bilateral mid palmar ulnar sensory action potential all have normal peak onset distal latencies, amplitudes, and conduction velocities. (fibromyalgiaforums.org)
  • Distal, motor, sensory velocities and sensory amplitudes were all clearly normal. (fibromyalgiaforums.org)
  • We have studied patients with symptoms of sensory neuropathy and controls using CHEPS, and validated the findings using other objective measures of small nerve fibres i.e. the histamine-induced skin flare response and intra-epidermal fibres (IEF), and also quantitative sensory testing (QST), a subjective measure. (biomedcentral.com)
  • In patients with symptoms of sensory neuropathy (n = 41) and healthy controls (n = 9) we performed clinical examination, QST (monofilament, vibration and thermal perception thresholds), nerve conduction studies, histamine-induced skin flares and CHEPS. (biomedcentral.com)
  • Diagnosis of sensory peripheral neuropathy is usually by nerve conduction studies, which assess mainly large sensory fibre dysfunction. (biomedcentral.com)
  • To assess small sensory fibre function, methods such as thermal quantitative sensory testing (QST) are commonly applied. (biomedcentral.com)
  • The Historical-Objective Scale, standard neurography, conduction velocity distribution tests (CVD), and quantitative sensory testing (QST) were performed before and after CTS surgery. (bvsalud.org)
  • Standard sensory conduction tests in the median and ulnar nerves were performed together with the estimation of vibratory, temperature, and warm- and cold-induced pain thresholds in the C7 and C8 dermatomes on the palm, using quantitative sensory testing. (bvsalud.org)
  • RESULTS: There were no statistically significant differences in the standard sensory conduction test in the median and ulnar nerves across the whole group: between right and left hands, and between women and men. (bvsalud.org)
  • The Contact Heat Evoked Potential Stimulator (CHEPS) rapidly stimulates cutaneous small nerve fibres, and resulting evoked potentials can be recorded from the scalp. (biomedcentral.com)
  • Nerve conduction studies and biopsy findings are compatible with demyelination. (medscape.com)
  • Electromyography (EMG) and nerve conduction studies show axonal degeneration and asymmetric involvement. (medscape.com)
  • Nerve conduction studies are mildly slow. (medscape.com)
  • DISCUSSION: The results of standard conduction tests of all nerves significantly differed between groups. (bvsalud.org)
  • Besides the findings of the NCV showing both of your ulnar nerves being pinched at the elbow (extremely common), that EMG is completely normal. (fibromyalgiaforums.org)
  • Results: Clinical improvement was observed on average in 54.3% of the patients, higher in less advanced CTS. (bvsalud.org)
  • QST seemed to be useful in the diagnosis of residual signs, and in deciding upon possible reoperation. (bvsalud.org)
  • The latency of sympathetic skin responses achieved from the foot was also statistically significantly prolonged in the study group. (bvsalud.org)
  • CHEPS appears a sensitive measure, with abnormalities observed in some symptomatic patients who did not have significant IEF loss and/or QST abnormalities. (biomedcentral.com)
  • Myoinositol and taurine depletion have been associated with reduced Na+/K+ -ATPase activity and decreased nerve conduction velocities (NCVs), all of which are corrected by aldose reductase inhibitors in rat studies. (medscape.com)
  • NCS abnormalities in demyelinating polyneuropathies can include prolonged distal and F-wave latencies, decreased conduction velocities, and conduction block. (medscape.com)
  • Results from the Diabetes Control and Complications Trial (DCCT) demonstrated that hyperglycemia and insulin deficiency contribute to the development of diabetic neuropathy and that glycemia reduction lowers the risk of developing diabetic neuropathy by 60% over 5 years. (medscape.com)
