Strains to the hamstring muscle group are prevalent and, unfortunately
, often recurrent, with prolonged rehabilitation and persistent disabi
lity. Most hamstring injuries are of a single muscle near the muscle-t
endon junction. Rarely, the hamstring muscle group may avulse from the
ischial tuberosity. The diagnosis can usually be made by history and
physical exam, but MRI can be used to help pinpoint the extent and loc
ation of the injury. Initial treatment typically consists of rest, ice
, compression, elevation, and pain relief. There is no consensus on op
timal rehabilitation, but functional exercises with stretching and str
engthening have been emphasized.
