Previous studies did not take into account the cumulative exposure to keyboard strokes among computer workers. The aim of the present study was to investigate the association between cumulative keyboard use (keyboard strokes) and CTS.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Employees (461) from a Governmental data entry &amp; processing unit agreed to participate (response rate: 84.1\u2009%) in a cross-sectional study. \u0391 questionnaire was distributed to the participants to obtain information on socio-demographics and risk factors for CTS. The participants were examined for signs and symptoms related to CTS and were asked if they had previous history or surgery for CTS. The cumulative amount of the keyboard strokes per worker per year was calculated by the use of payroll\u2019s registry. Two case definitions for CTS were used. The first included subjects with personal history\/surgery for CTS while the second included subjects that belonged to the first case definition plus those participants were identified through clinical examination.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Multivariate analysis used for both case definitions, indicated that those employees with high cumulative exposure to keyboard strokes were at increased risk of CTS (case definition A: OR\u2009=\u20092.23;95\u2009% CI\u2009=\u20091.09-4.52 and case definition B: OR\u2009=\u20092.41; 95%CI\u2009=\u20091.36-4.25).

Cumulative exposure to key-board strokes would be taken into account as an exposure indicator regarding exposure assessment of computer workers. Further research is needed in order to test the results of the current study and assess causality between cumulative keyboard strokes and development of CT.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1745-6673-7-16","type":"journal-article","created":{"date-parts":[[2012,8,2]],"date-time":"2012-08-02T10:14:26Z","timestamp":1343902466000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Cumulative keyboard strokes: a possible risk factor for carpal tunnel syndrome"],"prefix":"10.1186","volume":"7","author":[{"given":"Andreas","family":"Eleftheriou","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Rachiotis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Socratis E","family":"Varitimidis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charilaos","family":"Koutis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos N","family":"Malizos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christos","family":"Hadjichristodouloul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2012,8,2]]},"reference":[{"key":"203_CR1","volume-title":"Entrapment neuropathies","author":"DM Dawson","year":"1990","unstructured":"Dawson DM, Hallett M, Millender LH: Entrapment neuropathies.
