초록/요약
Objective To demonstrate the electrodiagnostic and ultrasonographic features of median nerve in elite wheelchair basketball players who were consistently exposed to repetitive propulsion-related trauma. Methods Fifteen elite wheelchair basketball players of Korean Wheelchair Basketball Federation (KWBF) with a non-progressive disability using a manual wheelchair as a primary transport were enrolled. All participants completed a questionnaire regarding symptoms of carpal tunnel syndrome (CTS) and demographics. After brief physical examination, electrodiagnostic and ultrasonographic evaluation of both median nerves including inching tests were performed. Results The median age of the participants was 40 years (range, 27-54), with an average 15 years of wheelchair use. Fourteen (47%) of 30 hands had electrodiagnostic evidence of CTS. All participants with CTS were mildly involved in both upper extremities. Subjects with CTS had a significantly greater (p=.014) duration of wheelchair use (25.0 years) compared with the normal participants (14.5 years). Athletes with CTS had a greater (p=.040) body mass index (26.0) compared to the normal subjects (23.4). Inching tests showed that most common site (86%) of abnormal conduction delay was 3cm and 4cm distal to the distal wrist crease (DWC). In ultrasonographic evaluation, we found that subjects with CTS had greater (p=.001) cross sectional area (CSA) of median nerve at DWC, 0.5cm and 1cm proximal to the DWC both in dominant and non-dominant hand than normal participants. The median motor distal latency (MMDL) showed correlation with CSA throughout carpal tunnel, including inlet and outlet. The median sensory proximal latency (MSPL) correlated with CSA only at inlet. On the other hand, the median motor distal amplitude (MMDA) and median sensory proximal amplitude (MSPA) negatively correlated with CSA distal to the DWC, limited in range. Conclusions The prevalence of CTS in wheelchair athletes appears to be similar to that of general paraplegic patients. The most common sites of conduction delay and nerve swelling in wrist region are also similar to those of general CTS population. Early recognition and management of CTS in these players will be helpful to promote quality of life and improve performance.
