Description:Objective
Evaluate associations between personal and workplace factors and median nerve conduction latency at the wrist.
Methods
Baseline data on workplace psychosocial and physical exposures were pooled from five prospective studies of production and service workers (N=2396). During the follow-up period, electrophysiologic measures of median nerve function were collected at regular intervals.
Results
Significant adjusted associations were observed between age, BMI, gender, peak hand force, duration of forceful hand exertions, TLV for HAL, forceful repetition rate, wrist extension, and decision latitude on median nerve latencies.
Conclusions
Occupational and non-occupational factors have adverse effects on median nerve function. Measuring median nerve function eliminates possible reporting bias that may affect symptom-based carpal tunnel syndrome (CTS) case definitions. These results suggest that previously observed associations between CTS and occupational factors are not the result of such reporting bias.
