The purpose of this study was to determine the natural history of symptomatic hands without electrodiagnostic evidence of carpal tunnel syndrome (CTS).
This study was comprised of 88 hands of 49 subjects with symptoms consistent with CTS without median mononeuropathy who were recruited during a community health examination and followed after two years. 88 hands of 44 people with age and sex-matched healthy controls were followed for comparison. Symptoms and electrodiagnostic findings were compared between the two groups.
62 hands of the symptomatic group had persistent symptoms after 2 years while 16 hands of the control group had symptoms consistent with CTS. Median motor distal latencies were significantly delayed after two years in the symptomatic group (p<0.05). Median sensory latencies were also delayed in the symptomatic group, but this was not statistically significant (p=0.064). The occurrence rate of median mononeuropathy at wrist was significantly higher in the symptomatic group than in the control group (13.6% vs. 2.3%)(p<0.05).
The results of this study suggested that a significant number of symptomatic hands without electrodiagnostic evidence of CTS may have persistent symptoms and may progress to electrodiagnostically evident CTS. (J Korean Acad Rehab Med 2006; 30: 346-352)
