In recent years, there have been a number of proposals for alternative grading systems. While there is recent evidence regarding the prognostic features of muscle injuries, this evidence has not often been incorporated into the grading proposals. The British Athletics Muscle Injury Classification proposes a new system, based on the available evidence, which should provide a sound diagnostic base for therapeutic decision-making and prognostication. Injuries are graded 0\u20134 based on MRI features, with Grades 1\u20134 including an additional suffix \u2018a\u2019, \u2018b\u2019 or \u2018c\u2019 if the injury is \u2018myofascial\u2019, \u2018musculo-tendinous\u2019 or \u2018intratendinous\u2019. Retrospective and prospective studies in elite track and field athletes are underway to validate the classification for use in hamstring muscle injury management. It is intended that this grading system can provide a suitable diagnostic framework for enhanced clinical decision-making in the management of muscle injuries and assist with future research to inform the development of improved prevention and management strategies.<\/jats:p>","DOI":"10.1136\/bjsports-2013-093302","type":"journal-article","created":{"date-parts":[[2014,7,16]],"date-time":"2014-07-16T23:01:13Z","timestamp":1405551673000},"page":"1347-1351","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":392,"title":["British athletics muscle injury classification: a new grading system"],"prefix":"10.1136","volume":"48","author":[{"given":"Noel","family":"Pollock","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven L J","family":"James","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin C","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Chakraverty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2014,7,16]]},"reference":[{"key":"2024051404533843000_48.18.1347.1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2011-090664"},{"key":"2024051404533843000_48.18.1347.2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2012-091008"},{"key":"2024051404533843000_48.18.1347.3","doi-asserted-by":"publisher","DOI":"10.1177\/0363546510395879"},{"key":"2024051404533843000_48.18.1347.4","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2002.002352"},{"key":"2024051404533843000_48.18.1347.5","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2005.018408"},{"key":"2024051404533843000_48.18.1347.6","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2005.018135"},{"key":"2024051404533843000_48.18.1347.7","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.36.1.39"},{"key":"2024051404533843000_48.18.1347.8","doi-asserted-by":"crossref","first-page":"379","DOI":"10.1177\/03635465030310030901","article-title":"Rates and risks of injury during intercollegiate basketball","volume":"31","author":"Meeuwisse","year":"2003","journal-title":"Am J Sports Med"},{"key":"2024051404533843000_48.18.1347.9","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2013-092380"},{"key":"2024051404533843000_48.18.1347.10","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-012-2055-x"},{"key":"2024051404533843000_48.18.1347.11","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1136\/bjsports-2011-090155","article-title":"Hamstring muscle injuries in professional football: the correlation of MRI findings with return to play","volume":"46","author":"Ekstrand","year":"2011","journal-title":"Br J Sports Med"},{"key":"2024051404533843000_48.18.1347.12","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.197.1.7568833"},{"key":"2024051404533843000_48.18.1347.13","doi-asserted-by":"crossref","first-page":"899","DOI":"10.7863\/jum.1995.14.12.899","article-title":"Sonographic findings in muscle strain injury: clinical and MR imaging correlation","volume":"14","author":"Takebayashi","year":"1995","journal-title":"J Ultrasound Med"},{"key":"2024051404533843000_48.18.1347.14","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-001-1164-6"},{"key":"2024051404533843000_48.18.1347.15","unstructured":"O'Donoghue DH .
