Abstract
Context
Biomechanical analyses of human movement require precise methods for quantifying measurements. The Modified Star Excursion Balance Test (mSEBT) is utilized by healthcare professionals and researchers to assess dynamic postural control. Despite its reliability, the manual application of mSEBT can introduce errors.
Objectives
(1) Develop a prototype using Arduino and a laser-sensor; (2) Evaluate and correct measurement errors using linear regression models; (3) Verify the reliability of the prototype under various configurations (height in relation to the ground, target distance, and test direction) of the mSEBT. Design: Observational Cross-sectional Case study.
Methods
Data were collected from a healthy participant using the mSEBT. The prototype was tested in various scenarios, encompassing different range directions, target distances, laser-sensor configurations, and heights from the ground. Linear regressions were applied to correct the values estimated by the prototype, and Intraclass Correlation coefficients (ICC) were calculated to validate the correction.
Results
The prototype presented systematic errors in certain scenarios, especially at distances of 10–40 cm and heights of 3–5 cm in relation to the ground. After applying linear regressions and reliability tests, the prototype demonstrated excellent reliability in all evaluation scenarios (r > 0.90; p < 0.001).
Conclusion
In summary, correction equations in the prototype algorithm derived from linear regressions of various test scenarios, which allows for the automation of measurements in the mSEBT clinical test. This advancement can enhance accuracy, efficiency, and clinical applicability, benefiting physiotherapists, physical educators, doctors, and biomechanics in monitoring dynamic postural control across diverse populations.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
