OBJECTIVES: hamstring strain @entity130 are the most common sports-related @entity121 and one of the main causes of missed sporting events. HYPOTHESIS: clinical findings reflecting @entity130 severity at presentation predict time to sports resumption. DESIGN: cohort study (prognosis); Level of evidence, 2. METHODS: five sports medicine specialists at four sports medicine centers prospectively evaluated 120 athletes within 5 days of acute @entity130 . @entity1 were interviewed and asked to evaluate their worst @entity158 on a visual analog scale (VAS). Four physical criteria were assessed at baseline: @entity2981 , @entity925 , @entity158 upon isometric contraction, and @entity158 upon passive straightening. The same standardized rehabilitation protocol was used in all @entity1 . A standardized telephone interview was conducted 45 days after the injury to determine the time to-full recovery ( <=40 days or >40 days). RESULTS: by univariate analysis, clinical criteria associated with a full recovery time >40 days were @entity227 score greater than 6, popping sound injury, @entity158 during everyday activities for more than 3 days, @entity2981 , and greater than 15   motion-range limitation. By multivariate analysis, only @entity227 score and @entity158 during everyday activities were significantly associated with time to recovery >40 days (53% sensitivity, 95% specificity). CONCLUSION: the initial examination provides valuable information that can be used to predict the time to full recovery after acute hamstring @entity130 in athletes.
