Evidence-based vestibular rehab for dizziness, balance problems, and visual motion sensitivity — and how MotionGuidance® visual feedback improves gaze stability, confidence, and carryover
What Is Vestibular Dysfunction?
Vestibular dysfunction is a broad category of conditions affecting the inner ear (peripheral vestibular system) and/or central pathways that integrate vestibular, visual, and somatosensory input. It commonly presents as:
-
dizziness or vertigo
-
imbalance / unsteadiness
-
blurred or “bouncy” vision with head movement (oscillopsia)
-
motion sensitivity and difficulty in visually busy environments
-
gait instability, especially with head turns
Common vestibular diagnoses include BPPV, unilateral or bilateral vestibular hypofunction, vestibular neuritis/labyrinthitis, PPPD, and vestibular involvement after concussion.
Which Systems Are Affected?
1) Gaze stability and the VOR
The vestibulo-ocular reflex (VOR) stabilizes vision during head motion. When it’s impaired, patients often feel dizzy or get blurred vision during normal movement.
2) Balance and postural control
Balance depends on the brain integrating vestibular input with vision and somatosensation. When vestibular input is disrupted, patients may become overly visually dependent or feel unsafe when the environment moves.
3) Sensory integration and “sensory reweighting”
A key rehab goal is helping the nervous system reweight sensory inputs appropriately (e.g., not over-relying on vision, improving stability when input is reduced or conflicting).
4) Cognitive load and confidence
Many patients struggle most in real life: walking while scanning, shopping aisles, crowds, multitasking, or uneven surfaces. Vestibular symptoms often worsen with dual-task demands and fear/avoidance.
Why Do Vestibular Symptoms Persist?
Vestibular rehab is often needed because compensation requires repeated exposure + accurate movement practice:
-
Patients may move too cautiously (or avoid movement), slowing adaptation
-
Movement errors are hard to detect without feedback (“Was my head speed enough?” “Did my eyes stay on target?”)
-
Exercises can become repetitive, reducing adherence
-
Some conditions require condition-specific interventions (e.g., BPPV requires repositioning maneuvers, not just exercises)
Evidence-Based Physical Therapy Approaches in Vestibular Rehab
A) BPPV: canalith repositioning
For posterior canal BPPV, guidelines strongly recommend treating with a particle repositioning maneuver (e.g., Epley), and avoiding routine vestibular suppressants as primary care.
B) Gaze stabilization (adaptation): VOR x1 / VOR x2
For vestibular hypofunction, there is strong evidence supporting vestibular rehab—especially gaze stability work with head movement. The APTA/ANPT guideline provides dosing guidance and supports supervised vestibular rehabilitation plus a home program.
C) Balance and gait training
Static/dynamic balance progressions, gait with head turns, and functional mobility work are core components.
D) Habituation
Repeated, graded exposure to symptom-provoking motions (in a controlled way) helps reduce motion sensitivity over time for appropriate patients.
E) Oculomotor drills
Oculomotor deficits (pursuits, saccades, convergence) are commonly addressed—especially in concussion-type presentations. However, for peripheral vestibular hypofunction, the updated CPG cautions against using smooth pursuit or saccades in isolation (without head movement) specifically to treat gaze stability. (They can still be relevant when treating the oculomotor system itself or concussion overlays.)
Where Traditional Vestibular Rehab Can Fall Short
Even good programs run into predictable barriers:
-
Patients can’t tell if head motion is fast enough or if gaze is truly stable
-
Therapists rely heavily on verbal cueing (hard to replicate at home)
-
Exercises get monotonous → adherence drops
-
It’s difficult to scale challenge precisely (speed, accuracy, complexity, dual-task)
-
Progression into real-world scenarios (busy environments, multitasking) is inconsistent
That’s exactly where visual feedback + external cues can elevate outcomes.
