If you play rugby league, AFL, soccer, or surf lifesaving in Australia, concussion is a real occupational hazard. You may have already been through one. And if you’re reading this, there’s a good chance you’ve been told to rest and wait, only to find that weeks later you’re still battling dizziness, headaches, nausea, or that unsettling feeling of the ground shifting beneath you.
For many athletes, these symptoms don’t simply disappear with rest. They persist because a concussion can disrupt the way your brain processes information from your inner ear and eyes, making everyday movements and returning to sport far more difficult than expected.
Vestibular physiotherapy for concussion recovery is an evidence-based treatment that targets these disruptions to help restore balance, reduce dizziness, improve visual stability, and support a safe return to sport. If your recovery has stalled despite following medical advice, vestibular rehabilitation may be the missing piece.
What Is the Vestibular System and Why Does It Matter After a Concussion?
Your vestibular system is the sensory network responsible for detecting head movement, spatial orientation, and balance. The key structures sit inside your inner ear: fluid-filled semicircular canals that detect rotational movement, and the otolith organs (the utricle and saccule), which contain tiny calcium carbonate crystals called otoconia. These crystals shift in response to gravity and linear acceleration, sending precise signals to your brain about where your body is in space.
Under normal circumstances, your brain integrates these inner ear signals seamlessly with input from your eyes and the proprioceptors in your joints and muscles. The result is smooth, accurate spatial awareness.
A concussion disrupts this process. The mechanical force of the impact can alter how the brain interprets vestibular signals, interfere with the neural pathways connecting the inner ear to visual processing centres, and in some cases physically dislodge the otoconia crystals, causing a condition called Benign Paroxysmal Positional Vertigo (BPPV).
BPPV is one of the most common and treatable post-concussion complications. When displaced crystals move into one of the semicircular canals, they create false signals about head movement. This produces intense, brief episodes of spinning triggered by specific head positions, such as rolling over in bed or tilting your head back. It is highly responsive to hands-on treatment and should not be left unaddressed. You can learn more about how this and related conditions are assessed and managed by reading our overview of vestibular disorders and how vestibular physiotherapy can help.
The Vestibulo-Ocular Reflex: Why You Feel Worse When Things Move
One of the most important mechanisms explaining post-concussion symptoms is the vestibulo-ocular reflex (VOR). This is the automatic system that stabilises your gaze when your head moves. When the VOR is functioning correctly, your eyes compensate for head movement in real time, keeping the visual world stable.
After a concussion, a disrupted VOR means your gaze cannot stabilise quickly enough. This is why athletes report blurred vision when tracking a ball, nausea in visually busy environments, difficulty reading, and a worsening of symptoms in crowds, shopping centres, or anywhere with a lot of visual movement. These are not separate problems. They are expressions of the same underlying vestibular disruption.
Why Passive Rest Stalls Recovery
The brain adapts and recovers through a process called neuroplasticity, which requires repeated, structured sensory input. Without specific vestibular challenges, the neural pathways responsible for balance and spatial processing do not strengthen or recalibrate. Rest removes the acute discomfort of symptoms temporarily, but it does not rebuild the system’s capacity to function under the physical demands of sport.
Put simply, the brain needs to be progressively challenged to compensate for the disruption. That is exactly what vestibular physiotherapy is designed to do, and it is a process that passive rest cannot replicate.
When should you seek assessment?
While rest is important during the first 24–48 hours, it is not a treatment strategy. If dizziness, balance problems, nausea, blurred vision, sensitivity to screens or busy environments, or movement-related symptoms persist beyond 48 hours, professional assessment is recommended. Early assessment allows your physiotherapist to determine whether symptoms are vestibular, visual, cervicogenic, or a combination, so treatment can be tailored appropriately.
Will symptoms resolve without treatment?
Some people recover naturally, but targeted vestibular rehabilitation consistently produces faster and more complete recovery for those with vestibular dysfunction. Without treatment, the brain can develop inefficient movement strategies, increasing the risk of prolonged dizziness, reduced confidence, and persistent post-concussion symptoms.
Does This Sound Like You?
These are the symptom patterns most commonly linked to vestibular involvement after a concussion:
-
- Dizziness or a spinning sensation, either constant or triggered by head movement
- Headaches that worsen with movement, screen use, or busy visual environments
- Nausea without a clear cause
- Blurred vision or difficulty tracking moving objects
- Balance problems, especially on uneven surfaces or with eyes closed
- A sense of floating, rocking, or unsteadiness when walking
- Symptoms that worsen in shopping centres, busy streets, or visually stimulating environments (this is called visual dependency and is a key clinical indicator)
- Brief, intense spinning triggered by specific head positions, such as lying down or looking up (consistent with BPPV)
If several of these apply to you, it is likely that vestibular dysfunction is contributing to your prolonged recovery. This pattern is not unusual. It simply means that the part of your recovery requiring active rehabilitation has not yet begun.
What Vestibular Physiotherapy May Involve
Before beginning any active rehabilitation program, having a formal medical assessment following your concussion is the appropriate first step. Once medical clearance is confirmed, vestibular physiotherapy can begin.
A vestibular physiotherapist with post-graduate training in neurological rehabilitation will conduct a comprehensive assessment covering several key areas:
-
- Gaze stability and VOR function. The therapist will assess how well your eyes stabilise during head movement, identify tracking deficits, and determine whether VOR dysfunction is contributing to your visual symptoms.
- Balance and postural control. This includes static and dynamic balance testing under various conditions, including standing with eyes closed and on unstable surfaces, to identify how much you are relying on vision to compensate for vestibular deficits.
- BPPV assessment. Specific positional tests, including the Dix-Hallpike manoeuvre, will determine whether displaced otoconia are present and which canal is affected. For athletes who want to understand what effective vertigo treatment looks like in practice, this assessment is typically where it begins.
- Cervicogenic contributions. This is an often-overlooked but clinically significant component. The upper cervical joints contain proprioceptors that feed directly into the same brain regions responsible for balance processing. Neck dysfunction after a concussion can compound vestibular symptoms and may need to be treated alongside inner ear rehabilitation. If you have neck stiffness or cervicogenic headaches following your concussion, this connection is worth discussing with your physiotherapist.
What a Session Looks Like
Many athletes wonder whether the exercises will make their symptoms worse. A well-designed vestibular program is deliberately calibrated to stay within your current tolerance. Mild, temporary symptom provocation during exercises is expected and normal. It signals that the system is being challenged in a productive way. What is avoided is pushing beyond the threshold that causes prolonged symptom flares or setbacks.
A first session typically runs between 45 and 60 minutes and focuses primarily on assessment. The therapist will gather a detailed picture of your symptom profile and test your vestibular, visual, and cervical function. If BPPV is identified, repositioning manoeuvres such as the Epley technique may be performed in the same session, often with rapid symptom relief.
A mid-program session is more active. You might work through gaze stabilisation exercises (moving your head while keeping a target in focus), habituation movements designed to progressively reduce sensitivity to triggering positions, and balance exercises progressing from simple standing tasks to dynamic movements that replicate sport-specific demands. Home exercises are prescribed alongside clinic sessions, typically 10 to 15 minutes daily, and are gradually progressed as your tolerance improves. Sessions are often weekly or fortnightly, depending on your stage of recovery.
The Rehabilitation Phases
Vestibular physiotherapy for post-concussion recovery follows a structured progression. Understanding these phases helps you gauge where you are and what to expect next.
-
- Phase 1: Acute Symptom Management (Weeks 1 to 2). The focus is reducing acute vestibular irritability, managing BPPV if present, and establishing a baseline of tolerable activity. Rest is still appropriate at this stage, but it is targeted rest, not blanket avoidance.
- Phase 2: Habituation (Weeks 2 to 4). Habituation exercises involve repeated, controlled exposure to movements that provoke mild symptoms. The goal is to reduce the brain’s sensitivity to those triggers through systematic desensitisation. Over time, the movements that previously caused significant dizziness begin to produce only a mild, manageable response.
- Phase 3: Adaptation and Substitution (Weeks 4 to 8). Adaptation exercises retrain the VOR and other vestibular-ocular systems to respond accurately despite the disruption caused by the concussion. Substitution strategies help the brain learn to rely more effectively on alternative sensory inputs when vestibular function remains partially compromised.
- Phase 4: Sport-Specific Integration (Weeks 8 onwards, depending on sport demands). Exercises are progressively loaded to replicate the demands of your specific sport. A rugby league forward requires different vestibular tolerance than a surfer or a soccer goalkeeper. Your therapist will program exercises reflecting the head movement patterns, visual tracking demands, and physical contact involved in your return to sport. For rugby league players in particular, our dedicated resource on rugby league physiotherapy outlines how sport-specific rehabilitation is structured at our clinics.
The risks of returning too early
Returning to training before vestibular function has recovered can impair balance, reaction time, and spatial awareness, increasing the risk of further injury. A second concussion before the first has resolved can significantly prolong recovery and, although uncommon, may lead to serious complications. Completing a structured rehabilitation program and receiving clearance from a qualified practitioner is the safest approach.

Frequently Asked Questions
How do I know if my dizziness is vestibular or just part of general concussion recovery?
Vestibular symptoms have a distinctive quality. They tend to be triggered or worsened by head movement, busy visual environments, or specific positions. They include a physical sense of movement, spinning, or unsteadiness rather than just cognitive fatigue or headache in isolation. If your dizziness is positional (triggered by lying down or looking up), worsens in crowded or visually busy spaces, or is accompanied by gaze instability and nausea, vestibular involvement is very likely.
Can I do vestibular exercises at home without seeing a physiotherapist?
Generic balance exercises found online are not the same as a prescribed vestibular program. The exercises need to be matched to your specific deficits, progressed at the right rate, and monitored for appropriate symptom response. An unsupervised programme can result in either insufficient challenge (no progress) or excessive provocation (setbacks). A physiotherapist assessment is the right starting point.
How long does vestibular physiotherapy take?
Recovery timelines vary depending on the severity of vestibular disruption, how long symptoms have been present before treatment began, and individual factors. Many athletes with straightforward vestibular dysfunction see significant improvement within four to eight weeks. More complex or longstanding presentations may require longer programmes. Early intervention generally correlates with shorter recovery times.
Does vestibular physiotherapy work for concussions that happened months or years ago?
Yes. The neuroplastic mechanisms that make vestibular rehabilitation effective are not limited to the acute recovery window. Athletes with persistent post-concussion symptoms from older injuries can still benefit significantly from targeted vestibular assessment and treatment, as the brain retains capacity to adapt and recalibrate with the right stimulus.
What should I tell my coach or team doctor?
If your symptoms have not resolved within the expected timeframe, asking for a referral to a physiotherapist with specific vestibular and concussion rehabilitation experience is reasonable and appropriate. The GRTS protocol requires input from a qualified clinician at each stage. Your coach cannot make that determination. A vestibular physiotherapist can provide objective evidence to support your return-to-sport decisions.
