In Reply: In response to Dr Nathan and colleagues,
we think that our study recognizes the multifactorial nature of tingling and
numbness in the hands. However, our findings do not call for a long-term longitudinal
study of the etiology of CTS among computer users. The cohort would have to
be so large that the efforts would outweigh the benefits if nerve conduction
studies were used to assess CTS. We feel quite confident that our diagnostic
method is reliable. As we stated, the exact same diagnostic approach but including
nerve conduction tests has been used and validated in another longitudinal
study of CTS.1,2 Therefore,
we know that both the prevalence and incidence would have dropped to approximately
one third of the interview values if nerve conduction tests had been included.
