Background:
Physical activity is beneficial in people with dementia. As physical activity increases risk exposure for falls, safety concerns arise. Prior exercise trials in people with dementia have not measured physical activity. Falls in relation to exposure time rather than person-years as outcome measure has been promoted but not investigated in people with dementia.
Methods:
Patients with mild to moderate dementia (n=110) were randomized to an intensive, progressive strength and functional training intervention or to a low-intensity group training for 12 weeks each. Physical activity was measured with a standardized questionnaire. Falls were documented prospectively by calendars for 12 months.
Results:
During the intervention, physical activity was significantly higher in the intervention group (P<0.001) without an increased fall rate (intervention group vs….
