Group physical activity for demented older adults feasibility and effectiveness

Abstract

Objectives: (1) To examine the feasibility of group physical activity in a day-care routine. (2) To assess the impact of this programme on functional fitness.

Design: Ten-week observational period, followed by 12 weeks of intervention in randomized controlled design, followed by 12 weeks of intervention only.

Setting: A day-care centre for demented older individuals.

Participants: Twenty-nine demented (Mini-Mental State Exam score 13.3 +/- 5.83) day-care attendees, mean +/- SD age 76.9 +/- 6.72.

Intervention: Group physical activity vs. social activity, followed by increased-intensity physical activity for both groups.

Measurements: Performance rate (PR) in physical activity sessions, Timed Get Up and Go (TGUG), Sit-to-Stand (STS) and Functional Reach (FR).

Results: Approximately 60% of the participants performed almost all movements or repetitions in both intervention phases. No improvements were observed following the first phase of physical activity. A reduction of 3.2 seconds (+/-1.2 SE) was noted in the time needed to perform the TGUG following the increased-intensity physical activity.

Conclusion: A carefully tailored group physical activity, conducted twice weekly with a group of 12-15 participants in a medium size room, and led by a physical activity teacher assisted by a staff aide, is feasible. Although physical activity performed mainly while sitting is ineffective, it can be effective to a meaningful degree when performed while standing or walking.
