The percentiles for the highest transfer height obtained are higher for phase 2 of the study. This is due to the limitations of the transfer station used in phase 1. The station used in phase 1 has a maximum height of 29 inches whereas the station used in phase 2 has a maximum of 43 inches. In phase 1 there were many people that reached the maximum, where as in phase 2 only a couple people reached the maximum.
