How Your Balance System Works — And What Happens When It Doesn't
Your sense of balance depends on three systems working in perfect coordination: your vestibular system (inner ear), your visual system (eyes), and your proprioceptive system (joints and muscles). When the vestibular system is disrupted, the brain receives conflicting signals — and the result is dizziness, vertigo, and a profound sense of unsteadiness.
The most common cause is Benign Paroxysmal Positional Vertigo (BPPV) — tiny calcium crystals in the inner ear that have moved out of position, sending false movement signals to the brain every time you change head position.
The good news: BPPV is highly treatable with specific repositioning maneuvers. Most patients experience dramatic relief within one or two sessions.
Common Symptoms of Vestibular Disorders
- Spinning Vertigo (BPPV): A sudden, intense spinning sensation triggered by rolling over in bed, looking up, or bending forward
- Persistent Dizziness: A constant "foggy" or unsteady feeling that never fully goes away
- Visual Disturbance: Difficulty focusing on moving objects, reading, or navigating busy environments like grocery stores
- Imbalance: Drifting to one side when walking, or fear of falling
- Nausea: Triggered by head movement or visual stimulation
Did your dizziness begin following a head injury or accident? This may indicate a concussion with a vestibular component — see our Concussion Recovery page for more information.
Clinical Red Flags: When to Seek Emergency Care
Most dizziness is vestibular in origin and safely treated with physiotherapy. However, seek immediate medical attention if dizziness is accompanied by:
- The 5 D's: Dizziness (constant and severe), Diplopia (double vision), Dysarthria (slurred speech), Dysphagia (difficulty swallowing), Drop Attacks
- Sudden severe headache unlike anything experienced before
- Neurological changes: Numbness, weakness, or difficulty speaking
- Hearing loss that comes on suddenly alongside vertigo
Exercises for Vertigo & Vestibular Rehab
- The Relief Position (Seated Stillness): When a vertigo episode strikes, sit down immediately on the nearest surface, fix your gaze on a single stationary point, and breathe slowly. Do not lie down until the spinning reduces — this can worsen BPPV.
- The Mobility Drill (Gaze Stability): Hold a card with a single letter at arm's length. Slowly move your head side-to-side while keeping the letter in sharp focus. Start with 30 seconds and build tolerance gradually.
- The Stability Focus (Tandem Standing): Stand with one foot directly in front of the other (heel-to-toe) near a counter for safety. Hold for 30 seconds with eyes open, then progress to eyes closed as your balance improves.
Please Note: Vestibular rehabilitation must be matched precisely to your specific diagnosis. The wrong exercises for the wrong vestibular condition can make symptoms worse. Your physiotherapist will create a customized vestibular rehabilitation program based on your full assessment findings.
Frequently Asked Questions: Vertigo & Vestibular Disorders
Most patients experience an 80–90% reduction in spinning sensations after just one or two sessions of canalith repositioning. The key is accurate diagnosis first — the maneuver must be matched to the specific canal affected.
Yes — and this is underappreciated. The unpredictability of vertigo episodes can create significant anxiety and avoidance of activities. As vestibular function improves with rehabilitation, most patients find their anxiety reduces alongside their physical symptoms.
Ready to Find Out What's Causing Your Dizziness?
Understanding your vestibular system is the first step. The next is a proper assessment that identifies exactly which system is involved — because the right treatment depends entirely on the right diagnosis. At Dynamic Physiotherapy, Mikayla will assess your inner ear, eyes, neck, and balance to pinpoint the cause and build a plan around it.
