Vertigo 4th level (1)
1. Overview of Vertigo
Definition: Vertigo is characterized by the sensation of movement, whether it's oneself or surrounding objects, leading to feelings of spinning or swaying and an overall sense of imbalance.
Etiology/Causes: Vertigo often stems from inner ear issues; common causes include:
Benign Paroxysmal Positional Vertigo (BPPV): Calcium particle clumping in inner ear canals leading to sudden vertigo during head movement; often age-related.
Meniere's Disease: Inner ear disorder from fluid buildup and changing pressure, causing episodes of vertigo, tinnitus, and hearing loss.
Vestibular Neuritis or Labyrinthitis: Viral infection causing inflammation in the inner ear, affecting balance.
Other Causes:
Head or neck injuries
Brain problems (e.g., stroke, tumor)
Certain ototoxic medications
Migraine headaches
2. Clinical Features of Vertigo
Symptoms:
Spinning, tilting, swaying sensations
Imbalance, pulled toward one direction
Nausea and vomiting
Abnormal eye movements (nystagmus)
Headaches, sweating
Ringing in the ears and potential hearing loss
3. Types of Vertigo
3.1 Peripheral Vertigo
Symptoms include:
Mild to moderate imbalance, nausea, vomiting, hearing loss, tinnitus, and ear fullness/pain.
Associated with internal auditory canal lesions possible facial weakness.
Typically improves within days to weeks.
3.2 Central Vertigo
Arises from injuries to the CNS balance centers (brainstem or cerebellum).
Often presents with less intense movement sensations and nausea, but may have neurologic deficits (e.g., slurred speech, double vision, and pathological nystagmus).
Can result in disequilibrium, a sensation of being off balance.
4. Role of Physical Therapy in Recovery
4.1 Treatment Goals
Decrease patient’s symptoms and subjective complaints.
Enhance gaze stabilization.
Improve functional balance skills and overall mobility.
Ensure patient safety during ambulation and activity.
Gain patient compliance and motivation.
Clarify treatment goals and implications of exercise.
Minimize symptoms through tailored exercise programs.
Empower patients with control over their rehabilitation process.
4.2 Treatment Approaches
Acute Phase
Encourage brief periods of activity followed by rest.
Gradually allow head movements while increasing visual stimulation.
Incorporate gentle head movements and VOR (Vestibular-Ocular Reflex) adaptation.
Progress activities from sitting to standing as tolerated.
Avoid bending over activities during this phase.
Post-Acute Program
Encourage head movements and visual focus during exercise.
Maximize adaptation of gaze stability and VOR.
Implement balance and gait activities, integrating various tasks.
Include community re-integration and walking programs.
Address any musculoskeletal issues during therapy.
4.3 Vestibular Rehabilitation Techniques
Habituation Exercises: To decrease dizziness with repeated exposure.
Gaze Stabilization: To improve visual focus stability during head movements.
Balancing Exercises: To enhance overall stability.
5. Specific Exercises for Recovery
5.1 Brandt-Daroff Exercises
Sequence of head turns and lying positions to relieve BPPV symptoms.
5.2 Semont Exercises
Rapid head turning and positional changes designed to dislodge calcium crystals impacting balance.
5.3 Epley Exercises
A series of specific head movements intended to alleviate BPPV symptoms by reorienting calcium crystals.
5.4 Foster Exercises
Exercises performed on hands and knees, involving head positions to reduce dizziness.
5.5 Cawthorne Exercises
Head and eye movements to promote engagement and balance coordination.
