A pilot study was used to determine the time constraints for the patients to tolerate the entire testing procedure (training, treatment, and gait evaluation) in a single block of time. From this pilot study, the following were determined: 1) one 10-minute period was the maximum amount of time that would be allowed for teaching the pelvic patterns to the subjects, 2) treatment would consist of four sets of five repetitions each with a 1-minute rest interval between sets, and 3) the subjects would walk with the same equipment they customarily had been using.
