Name of the Procedure:

Computerized Dynamic Posturography Sensory Organization Test (CDP-SOT), including Motor Control Test (MCT)

Summary

The Computerized Dynamic Posturography Sensory Organization Test (CDP-SOT) is a specialized assessment used to evaluate a person's balance and posture control. This test involves six different conditions that measure how well an individual can maintain balance under varying sensory conditions. The Motor Control Test (MCT) assesses reflexive responses to sudden movements of the platform.

Purpose

CDP-SOT is used to diagnose balance disorders and pinpoint the source of balance problems by assessing the interplay between vision, inner ear function, and proprioception (sense of body position). The MCT further evaluates the body's automatic responses to changes in its positioning. This helps in creating targeted rehabilitation plans for balance improvement.

Indications

• Patients experiencing unexplained dizziness or vertigo
• Individuals with a history of falls or imbalance
• Diagnosed vestibular disorders
• Neurological conditions affecting balance
• Pre-surgical and post-surgical evaluation of balance function

Preparation

• Wear comfortable clothing and flat, supportive shoes.
• Avoid consuming alcohol or caffeine 24 hours before the test.
• Inform the clinician about any medications currently being taken, as some might need to be adjusted or stopped.
• No specific fasting is required.

Procedure Description

1. The patient stands on a moveable platform in a safety harness to prevent falls.
2. Six different conditions are tested:
   • Eyes open
   • Eyes closed
   • Eyes open with visual sway (surrounding environment moves)
   • Eyes open with platform sway (platform moves)
   • Eyes closed with platform sway
   • Platform and visual sway simultaneously
3. Each condition measures the patient's ability to maintain balance, while sensors capture data for analysis.
4. The Motor Control Test involves unexpected movements of the platform to observe reflexive adjustments by the patient.
5. The data collected is interpreted to provide a comprehensive report on the patient's balance function.

Duration

The procedure typically takes about 30-45 minutes.

Setting

The test is performed in an outpatient clinic or hospital setting, specifically in a specialized balance or audiology lab.

Personnel

• Audiologist or physical therapist specializing in balance disorders
• Trained technician to operate equipment
• Support staff as necessary

Risks and Complications

• Minimal risk involved; high safety with the use of a harness
• Temporary discomfort or fatigue
• Rarely, patients may experience mild dizziness during the test

Benefits

• Accurate diagnosis of balance disorders
• Tailored treatment and rehabilitation plans based on detailed assessment
• Reduced risk of falls and improved overall balance

Recovery

• No specific post-procedure care; patients can resume normal activities immediately
• Follow-up appointments may be scheduled to discuss results and plan treatment

Alternatives

• Conventional balance tests and physical exams
• Vestibular function tests (e.g., VNG, caloric testing)
• Proprioceptive assessment without computerization Pros and cons of alternatives:
• Conventional tests may not be as comprehensive
• Vestibular tests focus more on inner ear function
• Non-computerized assessments might lack precision

Patient Experience

• The patient may feel slight disorientation or dizziness during the test
• Comfort measures include slow, controlled movements and reassurance by staff
• The harness system ensures safety and prevents falls during the testing procedures
