The Umeå Dementia and Exercise (UMDEX) Study

Research project The aim of the study is to evaluate effects of a high-intensity functional exercise program in people with dementia. Among the outcomes of interest are activities of daily living (ADL), falls, cognitive and physical function, and depressive symptoms.

Dementia is very common among older people; one out of three aged 85 or over has a dementia disease. Dementia leads to deteriorations in cognitive and physical functions, which contribute to an increased risk of dependency in activities of daily living (ADL) and falls. It will be of great importance for the care and treatment of people with dementia if an exercise programme decreases dependency in ADL and lower the risk of falls. Independence in ADL is important for life satisfaction among older people. Positive effects on ADL and fewer falls reduce the costs for society by less need of help from staff and fewer or shorter hospital stays.

Project description

Dementia is very common among older people; one out of three aged 85 or over has a dementia disease. The prevalence will increase dramatically in the future. Dementia leads to deteriorations in cognitive and physical functions, which contribute to an increased risk of dependency in activities of daily living (ADL) and falls.

The aim of the UMDEX study is to evaluate effects of a high-intensity functional exercise program in older people with dementia. Among the outcomes of interest are activities of daily living (ADL), falls, cognitive and physical function, and depressive symptoms.

186 older people with a diagnosed dementia and living in residential care facilities are included. Participants are cluster-randomized in small groups to an exercise programme (The High-Intensity Functional Exercise, HIFE, Program) or to a control activity. The exercise and control activity are held five times each 14 days for 4 months, in total 40 sessions. Outcomes are assessed at baseline, 4, and 7 months by persons blinded to group allocation. The study protocol (ISRCTN31767087) is published at the Current Controlled Trials (http://www.controlled-trials.com/ ).

It will be of great importance for the care and treatment of people with dementia if a high-intensity physical exercise programme decreases dependency in ADL and lower the risk of falls. Independence in ADL is important for life satisfaction among older people. Positive effects on ADL and fewer falls reduce the costs for society by less need of help from staff and fewer or shorter hospital stays.
