A novel measurement system for quantitative assessment of age-related sensori-motor degradation

摘要

Early identification of individuals with impaired balancing ability could lead to timely interventions and reduce the hazard of age-related falls. Numerous methods for researching the prevention of falls and age-related sensori-motor degradation have been proposed and tested. Most are either too expensive for practitioners or too physically demanding to use with seniors. A simple, reliable technique is desired. The aim of this research is to develop a practical and quantitative solution for assessment of age-related degradation of human sensori-motor function, which could in turn serve as a means of fall prevention among seniors. A novel testing apparatus, the dynamic balance testing platform, was developed. The design includes artificial neural network (ANN) technology to address the nonlinearity and redundancy in the neural network that controls sensori-motor functions. A total of 62 male subjects aged from 18 to 84 years were tested using the proposed method. Results showed that (1) the new device did reflect the sensori-motor degradation related to age, (2) reliable evaluation of sensori-motor function need not be complicated, time consuming, or costly, and (3) the developed equipment powered with ANN technology holds great potentials for predicting fall possibility. Overall, this study validated a strategy of fall prevention with a potential for prevalent use in the healthcare industry.
