What is Vestibular Rehabilitation?
Vestibular rehabilitation therapy (VRT) is a specialized type of treatment that tries to alleviate symptoms caused by vestibular illnesses, including vertigo, dizziness, gaze instability, imbalance, and falls. A personalized fitness and movement routine is developed based on the results of a clinical evaluation, laboratory and imaging tests, and patient input. Factors such as activity level, pain, other ailments, medications, and emotional stress can all influence healing.
At Hayer Physiotherapy, we conduct a complete subjective and objective evaluation to accurately diagnose your condition and develop an effective treatment plan. VRT uses highly specialized exercises to reduce the discomfort and symptoms associated with various inner ear and balance disorders.
The Vestibular System: What Is It?
The vestibular system provides fast compensatory movements in response to stimuli exerted both internally and externally. The peripheral vestibular system of the inner ear acts as a small accelerometer and inertial navigation system, constantly transmitting data regarding head and body movements and positions to integrative centers in the brainstem, cerebellum, and somatic sensory cortices.
Common Causes of Vestibular Conditions:
- Head trauma (e.g., motor vehicle accidents, sports injuries)
- Aging
- Inner ear infections
- Certain medications
- Stroke and brain injury
- Other systemic illnesses or diseases
Common Symptoms of Vertigo:
- A spinning sensation
- Feeling off-balance
- Nausea or vomiting
- Blurred vision
- Headaches
- Difficulty focusing
- Sensitivity to bright lights and noises
- Falling or stumbling
How Does Vestibular Therapy Work?
Dizziness and balance are inherently linked. Vestibular rehabilitation helps to control balance and mitigate vertigo symptoms. Knowing more about the reasons for your dizziness and how your body maintains equilibrium can help you understand how therapy works.
Understanding Dizziness
When something interferes with your sense of spatial orientation, you become dizzy. Your brain determines your body's position concerning your surroundings. When this is disrupted, you may experience lightheadedness, wobbliness, or the feeling that your sense of balance has been compromised.
The Mechanics of Balancing
The interaction of your sensory system and central nervous system (brain) dictates how well you maintain balance. Your sensory system relies on three main components:
1. Your Inner Ear's Vestibular Labyrinth
This comprises the otolith organs, which respond to movement and gravity, as well as the semicircular canals (loops), which respond when you tilt or turn your head.
2. Your Vision
The visual impulses your eyes send to your brain indicate your body's position relative to objects around you.
3. Your Muscles, Joints, and Skin
Your tissues are under pressure while your body moves. Your tissues send proprioceptive information to your brain, informing it of your spatial location. Leaning back while standing, for example, causes strain on the tissues in your lower thigh and rear foot, alerting your brain that you are bending.
Your central nervous system compiles this information and instructs your body on how to maintain balance. When this link is disrupted, the brain cannot process the information effectively. Vestibular therapy helps rebuild and recalibrate these connections, eventually reducing imbalance and vertigo symptoms.
Benefits of Vestibular Rehabilitation
Seeking professional, tailored treatment can drastically improve your stability, reduce dizziness, and enhance your quality of life. Research shows that vestibular rehabilitation therapy is highly effective for helping patients:
- Lower the chances of falling or stumbling
- Become more balanced and coordinated
- Significantly reduce symptoms of vertigo
- Improve eyesight stabilization abilities during head movement
- Strengthen the body and regain physical confidence
Risks Associated with Treatment
There are virtually no health risks linked with vestibular therapy. It is always conceivable that therapy will not fully resolve your balance or vertigo issues, especially if the underlying medical cause is progressive or if you cannot complete the prescribed home exercises consistently.
Your Initial Vestibular Assessment
Your treatment journey begins with a comprehensive verbal and physical assessment conducted by a registered physiotherapist.
What to Expect:
- Evaluation: The physical therapist will assess your cranial nerves, eye and head movements, and your baseline balance. We will also review your medical history and symptom triggers.
- Discussion: We will discuss the length, severity, and frequency of your symptoms, as well as the specific circumstances that amplify them.
- Workout Program: Based on the evaluation, your therapist will create a personalized treatment plan featuring specific exercises to reduce dizziness and train your balance systems.
