This paper reports the results of behavioral treatment to increase ambulation in three elderly wheelchair-dependent clients of an adult day care center. A multiple baseline across subjects design was used, in which one intervention was implemented (wheelchair restriction and contingent praise) and then a second intervention was added (prompts to take short walks). Each subject increased ambulation wrth intervention 1 and further improved with intervention 2. Mobility increased from an average 13.3 feet per day in baseline to an average 202.8 feet per day in intervention 1, and subsequently to an average 290.3 feet per day in the second intervention. © 1989 Taylor & Francis Group, LLC.
