Developed by the concussion in sport group, SCAT5 is a standardized tool used by Medical professionals and qualified health care professionals to aid in evaluation of athletes suspected of having sustained a concussion[1]. SCAT 5 can also be used to obtain baseline data among health athletes for future reference.

Intended Population

Athletes 13 years and over[1]


SCAT5 has 2 major components; An immediate/on-field assessment tool and an off-field assessment tool.

Immediate/on-field assessment comprises of;[2]

  • ·        Taking note of red flags,
  • ·        Checking for observable signs of concussion
  • ·        Memory assessment using Maddock's questionnaire
  • ·        Examining the level of consciousness using the Glasgow Comma Scale
  • ·        Cervical spine assessment

The off-field assessment is preferably carried out in a clinical setting and it involves:[2]

  • ·        Taking a comprehensive history of the players condition
  • ·        Symptom evaluation
  • ·        A cognitive screen, which is a measure of orientation and immediate memory.
  • ·        A measure of concentration
  • ·        A neurological screen
  • ·        Delayed recall 

The results of the assessment are compared to a previously conducted baseline assessment or to normative score and are used to confirm a concussion. 

Method of use

An athlete displaying obvious signs of concussion on pitch are immediately withdrawn from play and an immediate./on-field assessment is carried out[3]. In this case completing an off-field assessment is not required.

An athlete who gets involved in an event with potential to cause a concussion, but without obvious signs and symptoms of concussion may be allowed to continue playing while being monitored[1]. An off field assessment tool should then be completed after play.

Once SCAT5 is completed, results of each component are compared against the baseline. Any deviation from the baseline should lead to high level of suspicion for concussion.
