Comparison of Gait Speed Estimation of Multiple Sensor-Based Technologies

Abstract

In light of our aging population, there is an immediate need for non-obtrusive, continuous, and ubiquitous health monitoring technologies that will enable our population to age with a higher quality of life and independence. Research has demonstrated that gait indicators, such as walking speed, can reflect cognitive and physical functioning. However, gradual changes in such indicators usually go undetected until critical problems arise; being able to detect changes in indicators, such as gait deterioration, of older adults while in their home environments would enable clinicians to tailor more effective and personalized interventions by better understanding user behaviour in real-world settings. Real-world data is essential to enabling our healthcare system to act where patients most need help and to optimize the effect of designed eHealth solutions.

Use of Millimeter Wave FMCW Radar to Capture Gait Parameters

“…Lastly, while wearable sensors are less expensive and much more accurate [6], individuals are required to wear or carry a device on their body, which is not ideal for long term monitoring. Radar sensors could be one promising technique which could be used to monitor gait parameters frequently [7], [8].…”
