Training Dual-Task Walking After Stroke: Effects on Attentional and Locomotor Control

Community ambulation is a highly complex skill requiring the ability to adapt to increased
environmental complexity and perform multiple tasks simultaneously. Deficits in dual-tasking
may severely compromise the ability to participate fully in community living. Unfortunately,
current rehabilitation practice for stroke fails to adequately address dual-task limitations;
individuals with stroke continue to exhibit clinically significant dual-task costs on gait at
discharge. As a result, many stroke survivors are living in the community with residual
deficits that may increase disability in the real world and lead to falls with devastating
consequences. To address this issue, the proposed study investigates the efficacy of
dual-task gait training on attention allocation and locomotor performance in
community-dwelling stroke survivors. Because walking in the real world often requires
time-critical tasks and obstacle avoidance, the investigators will test the impact of
dual-task gait training on cognitive-motor interference during walking at preferred speed and
at maximal speed (Aim 1), and on locomotor control during obstacle negotiation (Aim 2). The
investigators will also evaluate the effects of the intervention on community reintegration
and participation (Aim 3).


Inclusion Criteria:

- Within 3 years of stroke onset

- Living in the community, operationally defined as living in one's own home, or the
home of a friend, relative, or caregiver

- Walking speed 0.6-1.1 m/s determined during 10-meter walk test

- Walk without the assistance of another person

- Medically stable and approved for participation by study physician

- Intact global cognition indicated by score > 23 on Montreal Cognitive Assessment

- Living in the community prior to stroke

Exclusion Criteria:

- Pre-existing neurological disorders (e.g., Parkinson's disease, Multiple Sclerosis,
dementia, traumatic brain injury)

- Previous stroke with residual motor deficit

- Uncontrolled hypertension

- Inability to follow 3-step command

- Primary uncontrolled hearing impairment

- Severe uncontrolled visual impairment

- Any speech-language impairment affecting ability to respond verbally to auditory
stimuli

- Timed Up and Go test > 15 seconds
