To assess the effects of practice on the gait measures, AFO's will be randomized for practice. Participants will be randomized for which AFO they will wear first. Then the participant will be provided with the selected type of AFO to practice with for the following week using a prescribed wearing schedule. At the end of the one-week practice time, the primary investigator will obtain the same measurements obtained at baseline with the participant wearing the type of AFO that was used to practice the week before. The same testing conditions and order of testing that were used at baseline will be employed. Once measurements are completed, the participant will be provided with the second type of AFO and will be asked to wear for one week using the same prescribed wearing schedule as before. Final measurements will be taken after completion of the one-week practice using the second type of AFO with the same testing conditions and orders. At the conclusion of testing each participant will be asked which AFO they will prefer to use.
