Forty-one teams (639 players) from four male senior soccer divisions at different levels of skill (divisions I-VI) were followed prospectively for 1 year. The exposure to soccer and the number of injuries per player were higher in higher divisions, but the injury incidence, percentage of ankle injuries and incidence of ankle injuries were the same at different levels of skill. Of all injuries 17 to 20% were ankle sprains and the incidence varied between 1.7 to 2.0 ankle injuries per 1000 hours of exposure. Since players with previous ankle problems run an increased risk of reinjury we suggest that these players receive preventive advice.<\/jats:p>","DOI":"10.1177\/107110079001100108","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"41-44","source":"Crossref","is-referenced-by-count":225,"title":["The Incidence of Ankle Sprains in Soccer"],"prefix":"10.1177","volume":"11","author":[{"given":"Jan","family":"Ekstrand","sequence":"first","affiliation":[{"name":"From the Sports Clinic, Department of Orthopaedics,\r               University Hospital, Link\u00f6ping, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Tropp","sequence":"additional","affiliation":[{"name":"From the Sports Clinic, Department of Orthopaedics,\r               University Hospital, Link\u00f6ping, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1990,8,1]]},"reference":[{"key":"bibr1-107110079001100108","unstructured":"1.
