Study Arms:
- Gait Modification Group (Type: EXPERIMENTAL): Participants will complete 4 months of a home-based progressive walking program with toe-out gait modification aimed at improving physical activity level. This group will perform continuous treadmill walking during regular sessions with a study therapist and will be instructed to perform a toe-out gait, with the aid of a mirror during walking. Focus will also be on increasing the time and distance of walking. These goals will be emphasized for the home-based portion of the intervention as well.
- Walking Only Group (Type: ACTIVE_COMPARATOR): Participants will complete 4 months of a home-based progressive walking program aimed at improving physical activity level. This group will perform continuous treadmill walking during regular sessions with the study therapist with focus on increasing the time and distance of walking. This goal will be emphasized for the home-based portion of the intervention as well.

Based on this trial design, predict the completion outcome and termination type (if applicable).
