Patent ID: 7878990

Claim:
A gait training device for detecting and correcting improper weight distribution during movement of an individual's body, in which said device comprises: two weight sensors with one of said weight sensors positioned under each of an individual's two feet and each of said weight sensors producing an output signal indicative of the weight on the sensor and wherein each of said weight sensors comprises an array of displacement transistors for converting mechanical pressure into an electrical signal; a microcomputer and means for inputting pre-selected target weights into said microcomputer; a control panel including a pair of window displays for displaying the forces applied by each leg of the individual and each of said window displays divided into two areas for displaying the time that each leg spends in a stance phase and a swing phase averaged over a number of gait cycles and said control panel including a pair of target weight selectors wherein each of said selectors include an up and down indicator for increasing or decreasing a target weight; a timer including an indicator, a start button and a reset button to measure the time of a session including multiple gate cycles on said control panel and a second set of buttons on said control panel for storing data and clearing said microcomputer in preparation for a different patient; a pair of cables connecting said weight sensors and said control panel to said microcomputer; said microcomputer including means for comparing the pre-selected weight and the sensed weight and computer memory that allows a clinician to monitor weight bearing data during a selected period of time, and also a speaker or sound buzzer that alerts a clinician and/or patient each time that a target weight is exceeded; means for indicating differences between pre-selected weights and sensed weights; and means for transferring the data from the gait training device to a personnel computer; which includes memory means for storing the weight distribution during multiple gait cycles and means for reviewing the memory for analyses by a clinician; and in which said weight sensors are Galium Arsenide displacement transistors.
