There is an urgent need for better techniques to assess physical activity (PA) in free-living populations. No existing method can accurately reflect duration, frequency, type and intensity of daily PA, which are crucial for the study of PA. Intelligent Device for Energy Expenditure and Activity (IDEEA®- a portable gait analysis system ) (MiniSun, Fresno, CA), a microcomputer-based measurement system, was developed to meet those needs. This small system enables recording of processed free-living data and other vital information with high reliability over 24-hour. More than 40 types of PA, including type, duration, frequency, and intensity have been evaluated. The table shows more than 99.3% of gaits were correctly counted and more than 99.18% of gaits were correctly classified. The error of walking and running speed prediction is 0.0036 °ņ 0.3708 mph and the correlation between predicted speed and actual speed is 0.9869. 


This device makes possible for the first time the quantitative study of daily PA with high accuracy. In addition, it can estimate the amount of mechanical work and related energy expenditure for 24-hour or longer, allowing study of relationships between PA and energy balance. Results from such studies can provide the basis for evaluation of the effectiveness of public health strategies used to promote PA for the prevention and treatment of obesity.
