Vestibular Hypofunction
Understanding and treating vestibular hypofunction through evidence-based VOR exercises and rehabilitation techniques
Vestibular Hypofunction
Vestibular hypofunction is a common vestibular disorder affecting 35.4% of adults in the United States. Its impact is significant, with annual healthcare costs reaching $3500-$13,000 per person depending on severity.
Understanding Vestibular Hypofunction
The vestibular system, located in your inner ear, plays a crucial role in balance and vision during head movements. When this system malfunctions, it can lead to significant impacts on daily life and function.
Primary Symptoms
- •Dizziness during head movements
- •Blurred vision while moving (oscillopsia)
- •Balance difficulties
- •Increased risk of falling
- •Motion sensitivity
Functional Impacts
- •Difficulty reading while moving
- •Challenges with walking in dark
- •Problems with quick head turns
- •Reduced independence in daily activities
- •Limited participation in dynamic activities
Types of Vestibular Hypofunction
Unilateral Vestibular Hypofunction
Affects one side of the vestibular system, often due to vestibular neuritis, surgical removal of tumors, or trauma.
- •Better prognosis with rehabilitation
- •May develop compensatory strategies
- •Often responds well to treatment
- •Typically affects one ear only
Bilateral Vestibular Hypofunction
Affects both sides of the vestibular system, usually from ototoxic medications, autoimmune conditions, or genetic factors.
- •More challenging recovery
- •Requires comprehensive rehabilitation
- •May need longer treatment duration
- •Often affects both ears simultaneously
Common Triggers
Movement-Related
Certain movements can trigger or worsen symptoms, particularly in uncompensated cases.
- •Quick head turns
- •Looking up or down
- •Bending over
- •Rolling over in bed
Environmental
Some environments can challenge the impaired vestibular system.
- •Dark or dimly lit areas
- •Uneven surfaces
- •Crowded spaces
- •Moving visual environments
Activity-Based
Certain activities may be particularly challenging.
- •Reading while moving
- •Walking on uneven ground
- •Sports activities
- •Driving
Warning Signs
Seek Immediate Medical Care If You Experience:
- ⚠Sudden onset of severe dizziness or vertigo
- ⚠Persistent vomiting or nausea
- ⚠New or severe headache
- ⚠Changes in hearing
- ⚠Facial weakness or numbness
- ⚠Double vision or vision changes
- ⚠Difficulty speaking or swallowing
- ⚠Loss of consciousness
