Automated assessment of postural stability system
Summary
A new Automated Assessment of Postural Stability (AAPS) system uses motion tracking to objectively score balance, improving upon the traditional Balance Error Scoring System (BESS) for clinical and field use.
Area of Science:
- Biomechanics
- Neuroscience
- Sports Medicine
Background:
- The Balance Error Scoring System (BESS) is widely used to assess static postural stability after injuries.
- Current BESS administration relies on subjective clinician observation, leading to potential bias and requiring trained personnel.
- Limitations exist in current motion capture systems for field-based balance assessment.
Purpose of the Study:
- To develop and validate a computerized system for objective balance assessment.
- To create an Automated Assessment of Postural Stability (AAPS) using low-cost motion tracking technology.
- To overcome the limitations of traditional BESS and existing motion capture systems for field application.
Main Methods:
- Development of a computerized balance assessment system (AAPS).
- Utilizing low-cost, commodity motion tracking technology for data acquisition.
- Field testing and calibration of the AAPS system for usability and accuracy.
Main Results:
- The AAPS system quantifies balance control objectively in field conditions.
- Designed for operation by minimally trained users with minimal setup.
- Eliminates the need for sensor calibration, unlike other systems.
Conclusions:
- The AAPS system offers a reliable and objective alternative to the traditional BESS test.
- Automated balance assessment is feasible and valuable for field use.
- This technology enhances the accuracy and accessibility of postural stability evaluations.
