The gait pattern was studied in thirty eight normal children, ranging in age from 1 to 14 years.
One cycle of human gait is composed of four phases, i. e. first phase: double posterior support of thrust, second phase: oscillating period, third phase: double anterior support of reception, fourth phase: unilateral support.
In order to analyse the gait, we tried to measure the duration time of each phase. We placed the tin plate, about twenty meters long, on the floor and made the shoes which were installed the electrodes on their toes and heels. We connected the four electric circuites between the tin plate and the electrodes on the shoes.
We ordered every subject to walk on the tin plate wearing the shoes for about five minites rhythmically. The four channeled data recorder had recorded continuously the contacting time of the electrodes with the tin plate as long as the subject walked. By using a Mediac-401 type of computer, we measured the duration time of the four phases and made the computer draw the four histograms. The peak of the histogram showed us the duration time of each phases and the dispersion of its showed us the stability of the walking.
The main findings were as follows.
1) The younger children pace more quickly than the elder ones.
2) The duration times of the first and third phases become shorter than that of adult.
3) The dispersion of each histogram is wider than that of adult.
