A research group at Nagoya University Graduate School, Aichi University Hospital, and Mikawa Aoitori Medical and Rehabilitation Center in Aichi Prefecture created standard values ​​for walking in Japanese elementary school children and investigated differences in lower limb movements during walking depending on age.For the first time, it was revealed that it is different from the movement of the lower limbs during walking of children in other countries.

 Walking is an important movement in daily life and reflects an individual's health.To assess a child's gait, age-appropriate reference values ​​are needed to assess normal development.However, domestic data on lower limb movements during walking by age of children are inadequate.

 The research group aimed to create a standard value for walking in Japanese elementary school children and to create a percentile growth curve for children's walking. Targeting elementary school children aged 2018 to 1 (2020: 3 boys, 6 girls) who participated in a child health checkup for exercise equipment health checkups from January 12 to March 424. I made it.

 Using a 11D motion analysis device, compare the acquired walking data of each age.As a result, it was found that the movements of the hip and knee joints gradually decreased with increasing age, but the movements of the ankle joints did not change much. For 12-1 years old, the maximum angle at which the knee bends when the foot is off the ground is small, and the range of motion of the knee while walking is also small.Also, the upper grades had a cleaner way of walking.Compared with data from other countries, Japanese elementary school children had light hip joint movements during walking, and in the upper grades, their stride lengths became shorter and the number of steps per minute increased.

 The results will be an important tool for assessing normal and pathological gait, and can be used not only to check the gait status of children, but also to determine the effects of orthopedic treatment and rehabilitation for gait disorders. ..
