Abstract

Objective
To investigate the frequency of carpal tunnel syndrome (CTS) according to the severity of diabetic polyneuropathy.
Method
Electrophysiologic study was performed in 456 patients (male 222, female 233, average age 58) with diabetes mellitus. Electrophysiologically diagnosed diabetic neuropathy was classified as suspected, probable or definite. CTS was also diagnosed both in cases with and without underlying diabetic peripheral neuropathy. The ANOVA test was used for statistical analysis.
Results
Out of 456 diabetic patients, 228 patients were diagnosed as diabetic peripheral neuropathy. The patients with diabetic neuropathy consisted of 107 cases (23.5%) of sus-pected group, 95 cases (20.8%) of probable group and 26 cases (5.7%) of definite group. The frequencies of concomitant CTS were 49 cases (21.5%) in 228 diabetic patients without diabetic polyneuropathy, 31 cases (29%) in suspected group and 30 cases (31.6%) in probable group. These were statistically significant. However, only one case showed concomitant CTS in 26 cases of definite group.
Conclusion
The frequency of CTS was higher in probable group compared to suspected group. However the frequency decreased in definite group because there is a difficulty in the differential diagnosis of two disease in the cases of advanced peripheral neuropathy. (J Korean Acad Rehab Med 2005; 29: 272-275)
