Carpal tunnel syndrome in Rochester, Minnesota, 1961 to 1980

Abstract

The incidence of carpal tunnel syndrome in the population of Rochester, Minnesota, from 1961 through 1980 was determined by use of the medical records-linkage system of the Rochester Epidemiology Program Project at the Mayo Clinic; 1,016 patients (1,600 affected hands) were identified. Incidence (cases per 100,000 person-years) was 99 (crude) overall, whereas the age-adjusted rates were 52 for the men, 149 for the women, and 105 for both sexes combined. Age-adjusted incidence rates increased from 88 during the 1961 to 1965 quinquennium to 125 during the 1976 to 1980 quinquennium; these rates probably reflect better recognition rather than a true increase in incidence rates. Age-specific rates generally increased with age in men, whereas in women a peak was reached in the 45 to 54 age group.

The Development of a New Orthosis (Neuro-Orthosis) for Patients with Carpal Tunnel Syndrome

“…5,6 In a study conducted in England 7 , the incidence of CTS in women and men was found to be 0.19% and 0.088% respectively. In another study, 8 the incidence rate was reported as 0.099, with a female to male ratio of 3:1.…”

Impact of occupations and job tasks on the prevalence of carpal tunnel syndrome.

“…A male-to-female ratio of 1:3 was described in a population study (39). There is yet no evidence for an increased female susceptibility for work-related CTS when exposure is controlled for.…”

Síndrome do túnel do carpo: controvérsias a respeito de diagnóstico clínico e eletrofisiológico e a relação com o trabalho

“…A STC é mais comum entre mulheres, atingindo pico de prevalência entre 45-54 anos 10 . As taxas de prevalência variam de acordo com a metodologia utilizada.…”

“…Certas manobras, como os testes de Tinel e Phalen, podem provocar os sintomas. Estes testes produzem alto número de resultados falso-positivos e falso-negativos, faltando pois especificidade e sensibilidade, o que os torna limitados como sinais clínicos 4,[10][11][12][13] .…”
