Tóm tắt

Both rheumatoid arthritis and diabetes have been associated with the development of abnormally high pressures under the feet, and ulceration has been considered to be a problem in both conditions. In order to examine further the relationship between high foot pressure, neurological abnormalities, and ulceration, we have studied two groups of patients: (a) 38 diabetic patients and (b) 37 patients with rheumatoid arthritis who had similar clinical abnormalities of the feet. Thirty‐two percent of diabetic patients had a history of plantar ulceration compared with none of the rheumatoid group (p < 0.01). However, the diabetic group had considerably more severe neuropathy (peroneal nerve motor conduction velocity 35.4 ± 4.8 m s−1 vs 44.4 ± 5.2 m s−1 (mean ± SD), p < 0.001; vibration perception threshold 33.5 ± 13.4 vs 16.9 ± 10.9, p < 0.001), with a similar frequency of elevated plantar pressures (51 % vs 61 %, NS). These data emphasize the importance of the loss of sensory awareness in the pathogenesis of diabetic foot ulceration, and suggest that high pressure alone is not a direct cause of ulceration.
