To evaluate sensory conduction of the median nerve and assess the prevalence and predictors of carpal tunnel syndrome among Japanese industrial workers compared to American cohorts.
Measured sensory conduction of the median nerve in 101 Japanese furniture factory workers and compared findings with 316 American workers across four industries.
Used a maximum latency difference (MLD) cutoff of ≥ 0.40 msec to identify abnormal nerve slowing.
Classified outcomes into probable carpal tunnel syndrome based on symptoms alone and definite carpal tunnel syndrome confirmed by electrophysiological slowing.
Abnormal median nerve slowing occurred in 17.8% of Japanese workers, which was not significantly different from the 22.0% observed in American workers.
Probable carpal tunnel syndrome was present in 2.5% and definite carpal tunnel syndrome in 2.0% of Japanese workers, rates substantially lower than those observed in American cohorts.
Body mass index was the primary predictor of maximum latency difference, while maximum latency difference was the primary predictor of probable carpal tunnel syndrome.

No takes yet. Share an insight, caveat, or question.

Implication

Cross-sectional study finds similar median nerve slowing but fewer carpal tunnel symptoms in Japanese industrial workers, suggesting occupational or cultural differences in symptom expression.
