One physical therapist and one medical student were given
specifi c training on the protocols for injury classifi cation and
injury defi nitions (see Soligard et al)33 before the start of the
injury recording period. These injury recorders called every
injured player to assess detailed aspects of the injury based on
a standardised injury questionnaire,34 and the players were in
most cases reached within 4 weeks (range 1 day to 5 months)
after the injury had occurred.
