Activity Arrangements with or Without Mobility and Performance of Persons with Profound Multiple Disabilities over Long Sessions

Abstract

Activity sessions with and without mobility were implemented with two persons with profound multiple disabilities to assess the effects of mobility on performance as well as the persons’ preferences between those two activity arrangements. Data showed differences concerning (1) the levels of on-task behaviour which were higher in the sessions with mobility for both persons, (2) the frequencies of activities carried out which were higher in the sessions without mobility for one person and the sessions with mobility for the other, and (3) the rates of activities per minute spent at the destinations which were higher in the sessions with mobility for both persons. Both persons preferred the arrangement with mobility. Implications of the findings are discussed.
