Causes of inner thigh walking seen in data (pechanko sitting)

Data of children with inner thigh gait who came to the hospital.

This time, I narrowed it down to sitting on a pet-chanko seat.


Number of visitors = 146 people
Gender ratio = 77% for men and 23% for women

As for pechanko sitting, as shown in the graph above, it was found that 70% of the children were sitting sitting in pechanko. However, even among these children, there were several children who answered that they did not sit on the floor, and when they actually sat on the floor, there were several children who were sitting on one leg, so I think this number is actually about 75~80%.
In addition, there were several people who sat in the hidden pechanko as follows.
(I thought I was sitting upright, but I sat with my lower legs going outward)



Consideration:
From this data, I think it is safe to judge that children who are prone to hip internal rotation (pechanko sitting habit) are correlated with inner thigh gait. Also, I think that children with inner thigh walking should continue to be careful not to do this pechanko sitting (including one leg and hiding) in childhood.
