Abstract

A method for measurements of parameters characterizing human motor activity provides registration of signals generated by load sensors mounted in shoe insoles, with each insole having at least two load sensors, one mounted near the heel, and the other near the toe of the foot. The specific type of motor activity is determined based on temporal correlation of load sensor signals from both insoles and values thereof. Person'"'"'s weight, including additionally carried weight, is determined by summing up signal values from said load sensors, with the specific type of motor activity considered; thereafter, person'"'"'s motor stress is determined based on specified type of motor activity and person'"'"'s weight, including additionally carried weight. The method enables a real-time monitoring of motor stress of a person at different types of motor activity, e.g. running, walking at different pace, standing, with person'"'"'s weight, including additionally carried weight, taken into consideration.

Claims

1. A method of determining weight of a person and additional weight carried by the person walking at a pace of up to 60 steps per minute, comprising:

providing the person with shoes each having (i) a first load sensor disposed in a heel region of a shoe insole and (ii) a second load sensor disposed in a toe region of the shoe insole;
