If your child plays club sport on the Mornington Peninsula, you may have heard coaches or clinicians talk about “baseline testing” for concussion. It’s a term that gets used a lot, but many parents and coaches aren’t quite sure what actually happens during one of these sessions, or what it’s measuring.
In simple terms, a baseline test is a snapshot of how a young athlete’s brain and body are functioning when they are well, healthy and free of any recent head knock. That snapshot then becomes a reference point that can be used later if a concussion is suspected. This article breaks down the three main areas a baseline test typically looks at, balance, reaction time and vision, and how they fit into a broader approach to concussion care in junior and community sport.
Why a baseline matters in the first place
Every person’s normal is different. One young athlete’s usual balance or reaction speed might look quite different to another’s, even if both are perfectly healthy. Without knowing what “normal” looks like for a particular individual, it can be genuinely difficult to tell whether a change after a knock to the head reflects a possible concussion, or is simply how that person always performs.
Baseline testing addresses this by recording an individual’s own starting point before the season begins. Osteopaths trained through frameworks such as Complete Concussions (CCMI) use standardised, evidence-informed tools so that if a comparison is ever needed later in the season, it’s being made against that same person’s own data rather than a generic average. This approach is designed to support informed decision-making around a possible head injury, not to diagnose or rule out concussion on its own, and it does not prevent concussion from occurring.
Balance: how the body controls stability
Balance relies on a constant, largely automatic conversation between the inner ear, the eyes, and sensors in the muscles and joints. A knock to the head can disrupt this system, sometimes in ways that aren’t obvious just from watching someone stand still.
During baseline testing, a clinician typically records how a person performs a series of standing balance tasks, such as standing on one leg or on a foam surface, with eyes open and closed. This gives a measurable picture of stability that can be revisited after a suspected injury.
- Single-leg stance and tandem (heel-to-toe) stance tasks
- Testing on both a firm surface and a compliant foam pad
- Recording the number of errors or wobbles within a set time frame
Reaction time: how quickly the brain responds
Reaction time reflects how efficiently the brain can process information and trigger a physical response. It’s relevant to everyday safety as well as sport, from reacting to a ball in netball or football (soccer) to responding quickly on a cricket pitch or basketball court.
Baseline reaction time is usually captured using simple, repeatable tasks, sometimes a drop-catch test, sometimes a screen-based tool, that measure how long it takes a person to respond to a visual or physical cue. Because reaction time can also be affected by fatigue, sleep and general alertness, having a personal baseline helps a clinician interpret any later change in context, rather than assuming a single slower result automatically means concussion.
Vision and eye movement control
Concussion can affect the visual system in ways that aren’t always picked up by a standard eyesight check. Baseline assessments often include tests of how smoothly the eyes track a moving object, how well they can focus when switching between near and far distances, and how the eyes coordinate with head movement.
These visual-vestibular tasks matter because so much of balance and coordination depends on accurate visual input. A young athlete who has difficulty with these tasks after a knock to the head, compared with their own baseline, may need further assessment before returning to full training or competition.
Cognitive screening alongside the physical tests
Most baseline assessments also include a brief cognitive component, looking at things like memory, concentration and processing speed. This isn’t a substitute for neuropsychological testing, but it adds another piece to the overall picture, particularly for symptoms that aren’t purely physical, such as difficulty concentrating in class after a head knock.
Together, the balance, reaction time, vision and cognitive components give a rounded view of how a person’s brain and body are functioning, rather than relying on any single measure in isolation.
How this fits into concussion care on the Peninsula
Baseline testing is one part of a broader, evidence-informed approach to head injury management. It doesn’t replace the need for urgent medical assessment if a serious head injury is suspected, and it doesn’t guarantee a safe return to play, no test can offer that guarantee. What it does is give clinicians, families and coaches better information to support decisions made together, in line with recognised guidelines used across Australian community and junior sport.
For families across McCrae, Dromana, Rosebud and Rye involved in local football, netball, basketball or cricket clubs, having this kind of concussion testing on the Mornington Peninsula available before the season starts means there’s a considered reference point ready if it’s ever needed.

Frequently asked questions
How long does a concussion baseline test take?
A typical baseline session runs for around 20 to 40 minutes, covering balance, reaction time, vision and a brief cognitive screen. Timing can vary depending on the clinic and how many athletes are being tested in a session.
How often should baseline testing be repeated?
Many clinics recommend re-testing baselines periodically, such as at the start of each season, since balance, reaction time and cognitive performance can change as young athletes grow and develop. Your osteopath can advise on a suitable schedule for your child’s age and sport.
Does a normal baseline mean my child won’t get concussed?
No. A baseline test is a reference measurement, not a preventive tool, and it cannot stop a concussion from happening. Its purpose is to give clinicians a personal comparison point if a head injury is later suspected.
Can baseline testing diagnose a concussion by itself?
No single test, including baseline testing, can diagnose concussion on its own. It forms part of a broader assessment process that should always include clinical review, and any suspected head injury should be assessed by an appropriate health professional.
Who typically needs a baseline test?
Baseline testing is most useful for young athletes involved in contact or collision sports such as football, netball, basketball or cricket, though any junior sports player can benefit from having a personal reference point recorded before the season begins.
