Ambulation with a mobility aid is a unique real-life situation of multi-tasking.
These simultaneous motor tasks place increased demands on executive function in
healthy young and older adults, but the demands have not been evaluated in people
with Alzheimer's disease (AD). Mobility problems are common among adults with AD,
leading to provision of a mobility aid to optimize independent activity. The
study objectives were: (i) to determine the dual-task cost (DTC) associated with
the use of a mobility aid in straight and complex path walking, and (ii) to
evaluate the association between executive function and ambulation with a
mobility aid in older adults with AD and age-sex matched cognitively normal
controls. Fourteen people (mean age+/-SD, 72.6+/-9.9years) with a diagnosis of
probable AD (MMSE range 12-25) and controls (mean age+/-SD, 72.9+/-9.5) walked at
a self-selected pace and using a 4-wheeled walker in a 6m straight path and a
Figure of 8 Test. Ambulation with the walker in a straight path produced a low
DTC that was not different between the groups.
Ambulation with the 4-wheeled
walker in the complex path produced a significantly different DTC in the group
with AD at -38.1+/-23.5% compared to -19.7+/-21.4%
(p=0.041). Lower scores on
executive function were associated with longer times across test conditions.
Ambulation with a 4-wheeled walker, in particular maneuvering around obstacles,
requires greater attentional costs in dementia. Future research should explore
the timing for safely introducing mobility aids in AD and the role of improving executive function.
