Determinants of Dual-task Gait Speed in Older Adults with and without Parkinson ’s Disease
Int J Sports Med DOI: 10.1055/a-2085-1429Mobility difficulties for people with Parkinson’s disease (PwPD) are more
pronounced when they perform a simultaneous cognitive task while walking.
Although it is known that neurodegeneration results in widespread motor and
brain impairments, few studies have comprehensively examined possible physical
and mental determinants of dual task walking in PwPD. In this cross-sectional
study, we aimed to investigate if and how muscle strength (sit-to-stand 30-sec
test), cognition (mini-mental state examination) and functionality (timed up and
go test) affect walking performance (10-meter walking test) with and without
arithmetic dual task from older adults with and without Parkinson’s
disease. Walking speed was reduced by 16% and 11% with
arithmetic dual task for PwPD (from 1.07±0.28 to
0.91±0.29 m.s−1, p<0.001) and
older adults (from 1.32±0.28 to
1.16±0.26 m.s−1, p=0.002)
compared to essential walking. The cognitive state was similar among the groups,
but it was only associated with the dual-task walking speed in PwPD. In PwPD,
lower limb strength was the better predictor of speed, whereas mobility was more
related to it in older adults. Therefore, future exercise interventions aiming
to improve walking in PwPD should consider these findings t...
