Name of the Procedure:
Computerized Dynamic Posturography Sensory Organization Test (CDP-SOT)
Summary
The Computerized Dynamic Posturography Sensory Organization Test (CDP-SOT) is a non-invasive test used to assess a person's balance and stability. It involves standing on a platform that can tilt and move under various conditions while body responses are measured.
Purpose
CDP-SOT is designed to evaluate balance disorders by determining how well a person can use input from their vision, proprioception (sense of body position), and vestibular system (inner ear balance mechanism). The goal is to pinpoint specific sensory and motor contributions to balance issues.
Indications
CDP-SOT is indicated for patients experiencing dizziness, vertigo, balance instability, previous falls, or other signs of balance disorders. It is suitable for individuals with suspected vestibular dysfunction or neurological conditions affecting balance.
Preparation
Patients are advised to wear comfortable clothing and remove any tight-fitting footwear. They should avoid consuming alcohol and, if instructed, refrain from taking certain medications that could affect balance. No other special preparation is typically required.
Procedure Description
- Condition 1 (Eyes Open, Stable Surface): The patient stands on a stable platform with eyes open.
- Condition 2 (Eyes Closed, Stable Surface): The patient stands on a stable platform with eyes closed.
- Condition 3 (Eyes Open, Visual Sway): The background moves, but the platform remains stable.
- Condition 4 (Eyes Open, Platform Sway): The platform tilts but the background remains stable.
- Condition 5 (Eyes Closed, Platform Sway): The patient stands with eyes closed on a tilting platform.
- Condition 6 (Eyes Open, Platform and Visual Sway): Both the platform and background move and sway.
Sensors and monitors record the patient’s body sway and stability during these conditions.
Duration
The procedure typically takes about 30 to 45 minutes.
Setting
CDP-SOT is usually performed in specialized outpatient clinics or hospital settings equipped with the necessary technology.
Personnel
The procedure is conducted by audiologists, physical therapists, or other trained healthcare professionals specialized in balance assessment.
Risks and Complications
CDP-SOT is a safe procedure with minimal risks. Rarely, patients may feel dizzy or off-balance during the test, but these sensations usually subside shortly after the procedure.
Benefits
The expected benefit of CDP-SOT is a comprehensive evaluation of the patient's balance system, leading to a tailored treatment plan. Findings can help manage and improve balance disorders effectively.
Recovery
No recovery time is needed. Patients can typically resume normal activities immediately after the test.
Alternatives
Alternative assessments might include traditional static posturography, vestibular function tests (like ENG/VNG), or other balance evaluations. Each method varies in complexity, specificity, and the type of information provided.
Patient Experience
Patients may initially feel unsteady during the test, especially during the more challenging conditions but healthcare professionals will be present for support. Discomfort is typically minimal, and any dizziness or unease usually resolves rapidly once the test concludes. Pain management is generally not necessary for this procedure.
