Sural-to-radial amplitude ratio in the diagnosis of diabetic sensorimotor polyneuropathy.
Abstract
In this investigation we measured sural and radial sensory potentials and the sural/radial amplitude ratio (SRAR) in 49 patients with diabetes and diabetic sensorimotor polyneuropathy (DSP) according to consensus criteria. Forty-five (92%) of the patients had a Toronto Clinical Neuropathy Score (TCNS) ≤5, which is consistent with a diagnosis of DSP. Using a threshold for SRAR of <0.21, we found no advantage of using the SRAR over the sural nerve potential amplitude alone in sensitivity for identification of DSP.
