Early detection of adult balance disorders is possible using posturography and personal data. Combining these factors improves accuracy, aiding timely intervention and better quality of life.
Area of Science:
- Biomedical Engineering
- Gerontology
- Clinical Biomechanics
Background:
- Early detection of balance disorders in adults is currently limited.
- Accessible data for identifying early-stage balance issues is needed.
Purpose of the Study:
- To identify adults in early stages of balance disorders.
- To utilize easily accessible and measurable data for early detection.
Main Methods:
- Utilized open-source data from 163 subjects (47 males, 116 females).
- Included posturography (center of pressure displacement), anthropometric/personal variables, and Trail Making Test scores.
- Trained and tested classification algorithms on 75% and 25% of the data, respectively, with validation on a healthy dataset.
Main Results:
- Including anthropometric and personal variables alongside center of pressure features improved classification accuracy and sensitivity.
- The standard deviation of center of pressure displacement was more effective than the mean value.
- Validation showed similar performance improvements, except when using neural networks.
Conclusions:
- Posturography, anthropometric measurements, personal data, and self-assessment scales can effectively identify balance issues in adults.
- This approach is suitable for resource-limited community health centers.
- Early detection facilitates timely medical care, improving disorder management and quality of life through rehabilitation.
