The distribution of diabetic neuropathy in a British clinic population

A survey of over 1,000 diabetic patients attending a routine hospital clinic clinic in a British city revealed 104 with neuropathic symptoms or foot ulceration. Patients could be assigned to one of four clinical neuropathy groups: chronic sensorimotor, predominantly sensory, proximal motor and mononeuropathy. Only duration of diabetes differed significantly between the groups, with the longest duration in the chronic sensorimotor group. Objective measures of neuropathy did not correlate with symptom scores indicating that careful clinical assessment must augment neurophysiological studies. Patients with neuropathic foot ulceration had significantly higher vibration and thermal thresholds compared with neuropathic patients without ulceration, whereas there was no difference in autonomic function between the two groups.
