Description

<p>There is a psychological dilemma associated with a loss of physical independence. Many people do not want to be stigmatized by having to use canes, wheelchairs, or other equipment that makes them appear disabled. Among the most challenging problems is that of decreased lower limb mobility, which restricts the distance a person can walk without assistance. Here we describe a hybrid mobility assistance device to address this issue. The device is four-wheeled, permitting the user to walk naturally while a servo motor amplifies normal walking speed. Its main components are a treadmill and two front driving wheels. Sensors in the treadmill detect anterior-posterior forces that are applied to the surface during walking. Rotational speed of the driving wheel motors is controlled by signals from these sensors. Computer software monitors the walking pattern as measured by the treadmill motor. Preliminary evaluations suggest that this device is both safe and effective for use by middle aged and older adults.</p>
