Providing a less restrictive environment for profoundly retarded persons by teaching independent walking skills.
Backward chaining travel training lets profoundly disabled adults walk independently to school, cutting staff escort time.
01Research in Context
What this study did
Four adults with profound intellectual disability lived in a state facility. Staff drove them to a nearby school each day. The researchers wanted the adults to walk the route alone. They broke the trip into small steps. They taught the last step first. This is called backward chaining. Each week they added the next step. Sessions happened on real sidewalks with normal traffic.
What they found
All four adults learned the full walk. They kept the skill for one to eight weeks without extra practice. Staff no longer had to escort them. Transport time dropped because the adults walked on their own.
How this fits with other research
Krentz et al. (2016) got the same result with a different tool. They paid tokens for every 50-meter lap. Adults with ID tripled their walking. The skill stuck even after tokens stopped. Both studies show large gains in outdoor walking for the same population. Smith et al. (2010) and Robertson et al. (2013) used walkers plus microswitches instead of chaining. Kids and adults took more steps when a favorite song played each time they pushed the walker. The tactic differs, but the outcome matches: more independent walking. ABelteki et al. (2025) applied the same backward chaining to older adults in long-term care. Surprisingly, leg strength did not improve, but fear of falling dropped and life-space mobility rose. The method still helps, yet the yardstick changes with age.
Why it matters
You can free up staff and give clients real independence. Pick a safe route near your facility. Break it into three to five chunks. Start at the end and chain backward. Use natural cues like crosswalk lights. Track walking time before and after. One month of daily 15-minute sessions can replace escort rides for adults with profound ID.

03Original abstract
A basic right of all handicapped persons is to live in the least restrictive environment possible. In this investigation, procedures were evaluated for teaching four institutionalized males with profound retardation necessary skills to increase their individual freedom of movement. Following baseline, a travel training program with a backward chaining format was implemented to teach each person to walk independently from his living area to school. Travel training included instructions, practice, praise, feedback, verbal reprimands, prompts, and edible reinforcers. Each resident began walking the entire distance to school independently during training and also began walking back to the living area, although the latter set of skills was not specifically trained. Following termination of the formal investigation, follow-up measures of 1 to 8 weeks showed the residents continued going to school independently. A survey of residential facilities in 43 states provided social validation for the seriousness of the problems associated with transporting seriously retarded persons to school. Also, time efficiency measures indicated that training independent travel resulted in reductions of staff time required in school transportation. Results were discussed in light of the potential contributions of behavior analysis in providing less restrictive environments for seriously handicapped persons.
