Procedure
Pre- and Post-Training Clinical Assessments. Clinical assessments included two measures of endurance (SixMinute
Endurance Walk and Energy Expenditure Index), two functional gait measures(Ten-Meter Walking Velocity and Gross Motor Function Measure Dimension E), and one static balance measure (Single Leg Balance Test). All clinical
assessments were conducted under the direction of an experienced pediatric physical therapist and occurred either
at the child’s school or a rehabilitation center. To providem as stable a measure of function as possible, a repeatedmeasures procedure was used when possible on the gait measures. Children performed the Ten-Meter Walking Velocity and Six-Minute Endurance Walk two to three times on separate days in the two-week period before BWSTT training, and two to three times in the two-week period after the training, with the exception of two children, who only received one post testing. Their repeated pre scores and post scores were averaged for analysis. Children were assessed on the Single Leg Balance Test and the GMFM one time in the two-week period before BWSTT training, and one time in the two-week period following the training.
