FULLY AMBULATORY, SELF-CONTAINED GAIT MONITOR

摘要

A gait monitoring device (10) for recording and assessing, with the use of a personal computer, the gait characteristics of one wearing the device, includes: (a) a transducer array (14) for sensing the temporal variation in the vertical acceleration and angular velocity of the motion of the shank of a wearer, (b) an analog to digital converter (18) for sampling the data sensed by the transducer array, (c) a microprocessor (12) having embedded programmable memory, (d) a sampled data storage means (20), (e) firmware (26) for controlling the operation of the microprocessor to sample the output of the transducer array at a prescribed time interval and to temporarily store the sampled data, (f) a USB interface (22) that allows for the downloading of the stored data to the personal computer, and (g) software for controlling a personal computer in the analysis of the collected data.
