Abstract
The authors devised five different kinds of balance board which varied progressively in design, and performed various kinds of balance test with them on 195 normal infants aged from two to six.
The tests showed that “standing on one foot” was most difficult for them to do, and it appeared that the balance reaction would emerge gradually at two years of age, grows rapidly with ages of three and above, and become perfect with children six years of age.
Based on these findings, the balance tests were performed on children with cerebral palsy, and the test results were studied for determination of characteristics according to types.
