Relationship Between the Pain Intensity at the Time of the Hamstring Muscle Injury and the Hyperintense T2 Weighted Volume of the Hamstring Muscle Lesion Measured by MRI.

Objectives: The primary objective of this study was to analyze the correlation between the pain experienced at the time of a hamstring muscle injury and the hyperintense T2 weighted volume of the lesion measured on MRI. The secondary objectives were to analyze the differences in this pain with the lesion grade and the hamstring muscle head involved.

Design: We performed a retrospective analysis of the data collected in a prospective, multicenter, noninterventional cohort study (HAMMER).
