Walking while talking: effect of task prioritization in the elderly
Verghese J, Kuslansky G, Holtzer R, Katz M, Xue X, Buschke H, Pahor M.. Archives of physical medicine and rehabilitation, 2007-01-01
Topic: Brain imaging, connectivity and assessment
Objective To examine the effect of 2 instructions on the same walking while talking (WWT) task on task prioritization by nondisabled subjects. Design Cross-sectional survey with within subject comparisons. Setting Community-based sample. Participants Older adults (N=189; mean age, 80.2+/-4.9y), who did not meet criteria from the Diagnostic and Statistical Manual, Fourth Edition, for dementia and were able to independently perform activities of daily living. Interventions Not applicable. Main outcome measures Verbal and gait measures on the same WWT task with 2 different instructions: paying attention to both talking and walking (WWT-C) and paying attention only to talking (WWT-T). Results Task prioritization effects were seen on walking but not on talking. Compared with their baseline normal walking velocity (without talking), subjects slowed down more on WWT-T (median change, 28.3%) than WWT-C (median change, 26.4%). Comparing the 2 WWT conditions, velocity and cadence was slower during WWT-T compared with WWT-C, with longer stride length. Verbal output was not significantly different on the 2 conditions. Conclusions Changing instructions while maintaining the same cognitive and motor tasks on WWT in older adults result in task prioritization effects.
Key findings
- Results Task prioritization effects were seen on walking but not on talking.
- Compared with their baseline normal walking velocity (without talking), subjects slowed down more on WWT-T (median change, 28.3%) than WWT-C (median change, 26.4%).
- Comparing the 2 WWT conditions, velocity and cadence was slower during WWT-T compared with WWT-C, with longer stride length.
- Verbal output was not significantly different on the 2 conditions.
- Conclusions Changing instructions while maintaining the same cognitive and motor tasks on WWT in older adults result in task prioritization effects.

How this study scored 55/100
Published in a peer-reviewed journal, and it is a snapshot of people at one point in time. Scored zero for randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 32 of the 58 points we could judge it on, which is 55 out of 100.
