Résumé : |
Objective To examine cognitive motor interference (CMI) during walking using a simple, standardized, and well-refined alphabet dual-task (DT) paradigm in individuals with multiple sclerosis (MS) in whom cognitive and walking impairment often co-occur. Design A single time point, cross-sectional study. Setting A university clinical laboratory. Participants Individuals with MS (N=61; mean age + SD, 50.8+9.3y) performed 4 walking trials over a 4.6-m walkway to determine gait parameters. Interventions Not applicable. Main Outcome Measures Gait parameters were assessed over 4 walking trials. The first 2 walks involved the single task (ST) of walking only; the second 2 walks involved participants performing the DT of reciting alternate letters of the alphabet while walking. The gait parameters recorded during the ST and DT walks were used to compute a dual-task cost (DTC) of walking (% change in gait parameter between ST and DT walks) as a metric of CMI. Results Our multivariate analysis with univariate follow-ups indicated CMI during walking based on slower velocity (ηp2=.59; F=84.6; P<.001 and cadence f="51.6;" p shorter step length increased time double-support in dt versus st conditions. the dtc of walking for gait parameters was not correlated with clinical disease duration demographic education age factors> Conclusions The alphabet DT paradigm is easily administered and well refined. We highlight its ability and acceptability to determine CMI during walking in people with MS, independent of disease status. |
