Despite there being several large-scale nerve conduction studies on large myelinated nerve parameters (15), the effects of glycemic control on small-fiber parameters, including skin innervation and neuropathic pain, remain elusive.
He subsequently underwent nerve conduction studies of the phrenic nerves which revealed a decreased conduction amplitude on the right side suggestive of a demyelinating neuropathy, but was not suggestive of Guillain-Barre syndrome.
A nerve conduction study was performed on cases and a clinical history, serum sample, and stool specimen obtained for all subjects.
Peripheral neuropathy status in the DCCT was defined by the presence of definite clinically evident distal symmetrical polyneuropathy and an abnormal nerve conduction study or based on responses to the Michigan Neuropathy Screening Instrument during EDIC (11).
Electromyography/nerve conduction studies performed on 14 patients with poliomyelitislike syndrome suggested a motor axonopathy and/or an anterior horn cell process.
In addition, the lack of abnormalities of the spinal cord on MRI, the absence of an F-wave on nerve conduction study (a possible sign of radiculopathy), and the absence of deep tendon reflexes without weakness support the possibility of radiculitis as a complication.
Motor conduction velocities on nerve conduction study are particularly helpful to classify sensorimotor polyneuropathies into demyelinating versus axonal pathophysiological subtypes.
37 Features of demyelination on nerve conduction study in patients with CMT are usually uniform and symmetric without conduction blocks or temporal dispersion.
The presence of f waves on nerve conduction study made Guillain-Barre syndrome an unlikely cause although there was evidence of demyelination.
