Carpal tunnel syndrome (CTS) is a common compressive neuropathy linked to disability in severe cases. Tools capable of distinguishing the severity spectrum median nerve entrapment in clinical practice are desirable.
This cross-sectional study included 58 CTS patients assisted in a Brazilian neurologic clinic. Participants were naive of surgical interventions and answered to Boston Carpal Tunnel Questionnaire (BCTQ). CTS was classified as mild, moderate, and severe according to electrodiagnostic testing.
There was no significant difference in BCTQ scores across the severity spectrum of median nerve entrapment, not even comparing mild cases with the group moderate/severe. Mild cases were younger (mean ± SD: 46.5 ± 9.2 years) than severe ones (60.0 ± 13.5, P = 0.04) and the group moderate/severe (55.5 ± 14.5, P = 0.01).
Results suggest that BCTQ is not adequate to assess the interpatient severity of median nerve entrapment on clinical practice.
