Bakgrund: Hamstringsskada är den vanligaste skadan inom elitfotboll och har hög återfallsrisk. I samband med hamstringsskador är arbetet intensivt då spelaren helst ska vara tillbaka snabbt för att bidra till lagets prestation. Rehabiliteringen behöver trots sin intensitet vara av långsiktig karaktär och förhindra att skadan återkommer i framtiden. Syfte: Att undersöka fysioterapeuters upplevelser av faktorer som påverkar rehabilitering av hamstringsskador hos herrfotbollsspelare i svenska elitfotbollsklubbar. Metod: Kvalitativ semistrukturerad intervjustudie med deskriptiv design. Ett ändamålsenligt urval gjordes och fem fysioterapeuter inom svensk elitfotboll intervjuades. Data analyserades med kvalitativ innehållsanalys med en induktiv ansats. Resultat: Analysen resulterade i fem kategorier och 19 underkategorier. Kategorierna var fysioterapeutens förutsättningar, spelarens förutsättningar, yttre press, bemötande av spelare och återgångens omständigheter. Med utgångspunkt i fysioterapeuters upplevelser framhålls spelaren, tränaren och den egna kunskapen som de mest betydande faktorerna av rehabiliteringen av hamstringsskador. Slutsats: Upplevelserna kunde kopplas till fysioterapeuten som individ, dess omgivning och beteende. Fysioterapeuterna upplevde att det krävdes anpassning av sitt beteende efter omständigheter i omgivningen för att åstadkomma en lyckosam rehabilitering. Studiens resultat är svårt att generalisera då antalet fysioterapeuter som medverkade i studien var få. / Bakground: Hamstring injury is the most common injury in elite football and has a high re- injury rate. The rehabilitation of hamstring injuries are intense since the player should preferably be back quickly to contribute to the team performance. Despite the intensity of the rehabilitation, it needs to be of a long-term perspective and prevent future re-injury. Aim: To explore physiotherapists’ experiences of factors that affect rehabilitation of hamstring injuries in male football players in Swedish elite football clubs. Method: Qualitative semistructured interview study with descriptive design. A purposive sample of five physiotherapists, working with Swedish elite football were interviewed. The data collection was analyzed with qualitative content analysis with an inductive approach. Result: The analysis resulted in five categories and 19 subcategories. The categories were the physiotherapist’s conditions, the player’s condition, external pressure, approach with the player and the circumstances of the return to play. The physiotherapists’ experienced that the player, the coach and the knowledge of the physiotherapist are the most important factors in rehabilitation of hamstring injuries. Conclusion: Physiotherapists experienced that adaptation of their behavior was required according to the circumstances of the surrounding environment to achieve successfull rehabilitation. The study’s result is difficult to generalize as the number of physiotherapists involved in the study was few.

Objectives To examine the relationship between Concussion Symptom Clusters (CSCs) and return-to-play time using a representative sample of U.S. college athletes with sports-related concussions. Background Recent evidence regarding concussion symptoms have been observed to be an important element of concussion severity, and potentially a predictor of return-to-play time. However, there is a paucity of data examining the associations between Concussion Symptom Clusters (CSCs) and return-to-play time in the U.S. college athlete population. Methods Data from the 2009-2010 to 2013-2014 academic years (n=1670) were obtained from the Datalys Center for Sports Injury and Prevention Inc. database. Exploratory factor analytic methods were applied, and the resulting factors were used in multinomial regression modeling to identify associations between CSCs and return-to-play time. ResultsA 4-factor solution accounted for 48.8% of the variance and included: audio-vestibular, somatic, amnesic, and affective factor structure. Audio-vestibular symptoms were associated with increased odds of prevented participation at 7-13 days, 14-29 days, greater than 30 days, and out for remainder of season, respectively (p Conclusion Specific CSCs were significantly associated with return-to-play time in college athletes, (p<0.05).
