When a young athlete takes a knock to the head during a weekend match in McCrae, Dromana or Rosebud, parents and coaches are often left asking the same question: has this affected them, and by how much? On its own, a single test after an injury can only tell part of the story. That is where baseline testing comes in — it gives clinicians a personal reference point to compare against, so post-injury results actually mean something.
Understanding how these two types of testing fit together can help parents, coaches and community clubs across the Mornington Peninsula make more informed choices when a head knock happens. Neither test alone is designed to diagnose or “clear” an athlete instantly — instead, they work as a pair, supporting a more complete picture over time.
What Is Baseline Testing?
Baseline testing is completed before any injury occurs, ideally at the start of a sporting season. It involves a series of measures covering balance, memory, reaction time, symptom reporting and cognitive processing, taken while the athlete is healthy. These results are stored and used as that individual’s own personal benchmark.
Because every athlete’s “normal” is different, a baseline test removes the guesswork. A score that might look unremarkable in isolation could actually represent a significant drop for one particular athlete, and baseline data helps highlight that difference.
What Is Post-Injury Testing?
Post-injury testing is carried out after a suspected head knock, using the same or similar measures as the baseline assessment. This allows a clinician to compare current performance against the athlete’s own pre-injury results, rather than against generic population averages.
Post-injury testing forms part of a broader clinical assessment — it does not stand alone. Symptom history, the mechanism of injury, and ongoing monitoring over subsequent days all contribute to the overall picture used to support decisions around rest, gradual return to activity and further review.
Why the Comparison Matters
The real value of concussion testing lies in the comparison between the two data sets, not in either test individually. Without a baseline, a clinician assessing an athlete after injury has to rely on broad population norms, which may not reflect that person’s usual cognitive or balance profile. With a baseline in place, the comparison becomes far more personalised.
This is a key part of the frameworks used by organisations such as Complete Concussions (CCMI), which our osteopaths at The Seaside Osteo are trained through. These frameworks emphasise a structured, individualised approach to concussion testing on the Mornington Peninsula, recognising that recovery and presentation can vary significantly from one young athlete to the next.
How This Supports Junior Athletes Locally
Community sport is a big part of life across the Peninsula, with junior athletes taking part in AFL, netball, football (soccer), basketball and cricket throughout the year. Head knocks can happen in any contact or collision sport, and having a baseline on file before the season starts means that, should an injury occur, clinicians have something meaningful to compare against straight away.
Some of the practical benefits of having both baseline and post-injury data available include:
- A more individualised comparison rather than reliance on general population norms
- Additional information to help support gradual return-to-play and return-to-learn planning alongside a treating clinician
- A structured, consistent process that families and coaches can follow if a head knock occurs
- Support for ongoing monitoring across the days and weeks following an injury, not just a single point-in-time check
What Baseline and Post-Injury Testing Do Not Replace
It is important to be clear about the limits of this process. Testing does not prevent concussion from occurring, and no combination of baseline and post-injury results can guarantee a safe return to sport. These tools are designed to inform and support clinical decision-making — they work alongside, not instead of, a comprehensive individual assessment by a qualified clinician.
Any suspected head injury should always be taken seriously. If in doubt, sit them out, and seek assessment from an appropriately trained health professional. Our team’s approach follows recognised guidelines such as those from the AFL and the CCMI framework, using concussion testing as one part of a broader, individualised assessment process.
Getting Started Before the Season Begins
Because baseline testing needs to happen before an injury occurs, the ideal time to book it in is at the start of the season, well before junior athletes across Dromana, Rosebud, Rye and surrounding suburbs take to the field. This gives clubs and families a personal reference point ready to go if it is ever needed.
Parents and coaches wanting to understand more about how this process works, or how osteopathy can support recovery more broadly, are welcome to explore our osteopathy services or join one of our community information sessions through our free concussion workshop.
Frequently asked questions
Do we need to redo baseline testing every year?
Many clinics recommend updating baseline testing periodically, particularly for younger athletes whose cognitive and physical development changes quickly. A clinician can advise on a suitable interval based on the athlete’s age and sport.
Can post-injury testing be used without a prior baseline?
Yes, post-injury assessment can still be carried out and compared against general population norms, but having an individual baseline generally allows for a more personalised comparison. It is one reason baseline testing before the season starts is encouraged.
How soon after a head knock should post-injury testing happen?
This depends on the individual situation and should be guided by a qualified clinician, as timing forms part of a broader assessment alongside symptoms and injury history. Any suspected concussion should be assessed promptly rather than waiting.
Does a normal test result mean it is safe to return to play immediately?
No single test result determines return-to-play on its own. Decisions are made gradually, following recognised guidelines and ongoing review by a treating clinician, taking the whole clinical picture into account.
Is baseline and post-injury testing only for elite athletes?
No, this approach is relevant for junior and community-level athletes as well as elite sport. Many local clubs across the Mornington Peninsula encourage baseline testing for young athletes participating in contact or collision sports.
