Verlo orthosis: experience with different developmental levels in normal children.

Fifty-three normal children ranging in age from 11 to 36 months were trained to ambulate 3 meters in the Verlo brace using a walkerette. The children were divided into five age groups: 11 to 15 months, 17 to 21 months, 22 to 27 months, 29 to 34 months, and 35 to 36 months. The age groups were compared with respect to the percentage in each group that completed the training protocol and the average number of minutes required by those subjects to do so. Results ranged from a low 36 percent completion with an average training time of 366 minutes in the youngest age group to a high of 100 percent completion with an average training time of 70 minutes in the oldest age group. There was an increasing tendency in the three older groups to resist getting into the brace.
