Effects of functional tasks exercise on older adults with cognitive impairment at risk of Alzheimer's disease: a randomised controlled trial.
OBJECTIVEthe aim of this study was to compare the effects of a functional tasks exercise programme to a cognitive training programme in older adults with mild cognitive impairment.
DESIGNa single-blind randomised control trial with the intervention group compared with an active control group.
PARTICIPANTSolder adults with mild cognitive impairment (n = 83) aged 60 and older living in the community.
METHODSparticipants were randomised to either a functional task exercise group (n = 43) or an active cognitive training group (n = 40) for 10 weeks. All outcome measures were undertaken at baseline, post-intervention and 6-month follow-up using Neurobehavioral Cognitive Status Examination, Trail Making Test, Chinese Version Verbal Learning Test, Category Verbal Learning Test, Lawton Instrumental Activities of Daily Living Scale and Problems in Everyday Living Test.
RESULTSthe functional task exercise group showed significant between-group differences in general cognitive functions, memory, executive function, functional status and everyday problem solving ability. The improvements were sustained over time at 6-month follow-up.
CONCLUSIONa functional tasks exercise programme is feasible for improving cognitive functions and functional status of older adults with mild cognitive impairment. This may serve as a cost-effective adjunct to the existing interventions for populations with mild cognitive impairment.
