This study investigated the effects of a functional mobility program on the functional standing and walking skills of five adults with developmental disabilities. The Mobility Opportunities Via Education (MOVE) Curriculum was implemented using a multiple-baseline across subjects design. Repeated measures were taken during baseline, intervention and maintenance phases for each participant. All participants demonstrated progress in time standing and number of reciprocal steps during intervention. Skill gains were maintained or improved two years following intervention. Results for each participant are discussed as well as implications and future directions for research. (Contains 4 figures.)
