How reliable are Functional Movement Screening scores? A systematic review of rater reliability.

Background: Several physical assessment protocols to identify intrinsic risk factors for injury aetiology related to movement quality have been described. The Functional Movement Screen (FMS) is a standardised, field-expedient test battery intended to assess movement quality and has been used clinically in preparticipation screening and in sports injury research.

Aim: To critically appraise and summarise research investigating the reliability of scores obtained using the FMS battery.
