Why What You Do Before a Concussion Matters Just as Much as What You Do After

When most people think about concussion management, they think about what happens after the injury. Rest, gradual return to activity, avoiding screens. But there is a growing body of evidence and clinical practice pointing to something that does not get nearly enough attention: what you do before a concussion ever happens.

Pre-injury preparation, particularly baseline concussion testing, is one of the most powerful tools available to athletes, active individuals, and their healthcare providers. Here is why it matters, and what it actually involves.

What Is Baseline Testing?

Baseline testing is a pre-season or pre-participation assessment conducted when a person is healthy and symptom-free. It captures a snapshot of how your brain functions normally, across areas like memory, reaction time, balance, concentration, and processing speed.

Think of it like a pre-purchase inspection on a vehicle. You document the condition of everything before anything goes wrong, so that if something does go wrong later, you have a clear reference point to measure recovery against.

Without a baseline, clinicians and athletes are essentially guessing. They are comparing post-injury results against population averages rather than the individual’s own normal. For someone who already performs at the lower end of a cognitive test due to a learning difference, anxiety, or simply how their brain is wired, this can lead to a premature return to play or, conversely, unnecessary hold-out.

What Does Baseline Assessment Include?

A comprehensive pre-concussion assessment typically covers several domains:

Cognitive testing looks at memory, attention, and processing speed. This can be conducted through validated computerised tools or in-person assessments with a trained clinician.

Symptom inventories capture how a person feels on a normal day. Many people live with low-level headaches, sleep disruption, or neck tension that could easily be misread as post-concussion symptoms if there is no baseline to compare against.

Balance and vestibular assessment evaluates postural stability and the relationship between the inner ear, eyes, and brain. This is an area where physiotherapists with concussion expertise play a particularly important role.

Oculomotor testing assesses how the eyes track, converge, and respond, functions that are frequently disrupted after concussion and often overlooked without pre-injury data.

Cervical screening documents neck strength, range of motion, and any pre-existing symptoms. The cervical spine is almost always involved in concussion mechanics, and pre-existing neck stiffness or weakness can both contribute to injury risk and complicate recovery.

Who Should Get Baseline Testing?

The short answer is anyone at meaningful risk of a head impact. That includes contact sport athletes at any level, from junior community sport through to elite competition. It also includes recreational athletes, cyclists, equestrians, and people in manual or high-risk occupations.

In Australian football specifically, the 2024 AFL return-to-play protocols now set a higher standard than ever for how concussion is managed during and after the season. But those protocols work best when there is solid pre-injury data to anchor the recovery process to. Without it, return-to-play decisions become harder to defend clinically and harder to navigate confidently for the athlete.

The Role of the Cervical Spine

One of the most underappreciated aspects of concussion prevention and preparation is the neck. Research increasingly supports the idea that cervical strength and proprioception play a protective role in reducing concussion risk. A stronger, better-conditioned neck can help absorb and dissipate some of the forces that would otherwise transmit directly to the brain.

Pre-season cervical assessment allows a physiotherapist to identify weakness or asymmetry and implement a targeted strengthening program before the season begins. This is not just about performance. It is genuine injury prevention.

What Happens If You Skip It?

Without baseline data, the clinician managing your concussion is working with one hand tied behind their back. They cannot tell whether your processing speed has dropped since injury, or whether it was always like that. They cannot determine whether your balance deficit is new or pre-existing. They are making educated guesses where they could be making precise comparisons.

This matters enormously when it comes to return-to-play and return-to-learn decisions. Getting back too early after concussion, even by a few days, significantly increases the risk of a second injury, and second impact syndrome, while rare, can have catastrophic consequences.

What to Expect From a Baseline Assessment

A baseline concussion assessment at a physiotherapy practice with concussion expertise is typically a relaxed, low-stakes appointment. There is nothing to study for and nothing to pass or fail. You simply attend when you are feeling well, complete the assessments, and your results are stored for comparison if an injury ever occurs.

The investment in time is small. The potential value, if you do sustain a concussion, is enormous.

Start Before the Season Does

The best time to get baseline testing done is before your sport or activity season begins, before training loads increase and before any risk of injury arises. If you are a coach, club administrator, or parent of a young athlete, this is something worth building into your pre-season calendar as a standard part of preparation, not an optional extra.
