Conclusion There is insufficient epidemiological evidence that computer work causes CTS
Background This review examines evidence for an association between  computer work and carpal tunnel syndrome ( CTS ) .
Prolonged median sensory latency as a predictor of future carpal tunnel syndrome.
The purpose of the study was to determine whether abnormal median sensory nerve conduction among asymptomatic workers was predictive of future symptoms suggestive of carpal tunnel syndrome ( CTS ) . This was a prospect i ve study involving 77 workers who were identified as asymptomatic cases with electrodiagnostic findings of median mononeuropathy compared to an age- and sex-matched control group . Follow-up was completed an average of 70 months later , and subjects who reported pain , numbness , tingling , or burning in the distribution of the median nerve , based upon a h and diagram , were classified as having CTS symptoms . The follow-up participation rate was 70 % . Among subjects with abnormal median sensory latencies , 23 % went on to develop symptoms consistent with CTS within the follow-up period , compared with 6 % in the control group ( P= .010 ) . Age and h and repetition were also risk factors for CTS , but the majority of asymptomatic workers with a median mononeuropathy do not become symptomatic over an extended time
