- Abstract
- Background
: The H-reflex has been used to assess the proximal nerve conduction in radiculopathy or peripheral
neuropathy. The purpose of this study was to evaluate the clinical usefulness of the H-reflex in the diagnosis of subclin-ical
diabetic polyneuropathy. Methods : Thirty-four diabetic patients (17 women and 17 men) who had neither motor
nor sensory symptoms were selected (mean age 57.6 ± 12.9 years). The duration of diabetes varied from 0.5 to 24 years
(mean 6.2 ± 5.1 years). None of the patients had any known cause of peripheral neuropathy other than diabetes.
Twenty-seven healthy subjects (16 women and 11 men) were evaluated as an age-matched control group. H-reflex
studies were performed using Braddom and Johnson’s methods. The presence and latencies of the H-reflexes were
examined in both legs. Results : Twenty-four of the 34 patients (70.6%) had abnormal H-reflex responses (absent H-reflex
in 17, prolonged latency in 7). However, only three out of the 27 control subjects (11.1%) had abnormal H-reflex
responses (absent H-reflex in 1, prolonged latency in 2). Conclusions : Abnormalities in H-reflex studies have often
been seen in diabetic subjects without overt neurological symptoms. This study suggests that the H-reflex study may be
a useful screening tool in the diagnosis of subclinical diabetic polyneuropathy.
