Gait Maturation Database

The data contained here are from 50 healthy children ranging in age from 40 months to 163 months. Each data file is named with a subject identifier (1-50) and the subject's age (e.g., the file name 2-45.txt indicates that subject #2 is 45 months old). Each data file contains two columns of data in text format. The first column is the time (in seconds), and the second column is the stride interval (in seconds) or the gait cycle duration, the time from heel strike to heel strike of the same foot.

A summary of pertinent data about the subjects is presented in the table below, which is also available as a text (.csv) file.
