简要总结
Goal of research program: To understand person-specific factors, such as imaging markers and activity patterns early after stroke, that may guide precision rehabilitation to optimize function and improve recovery.
Objectives:
- Test the effect of reducing sedentary behaviour early after stroke on functional mobility and global disability outcomes.
- Determine the impact of neuroimaging biomarkers (e.g. leukoaraiosis) on response to rehabilitation.
- Explore the predictive value of accelerometry as an adjunct to the subjective modified Rankin Scale (mRS) to assess functional disability after stroke.
Experimental approach/Research Plan/Use of Funds: The investigators aim to recruit 50 participants within 3 months of stroke onset, aged ≥ 18 years, medically stable as deemed by their physicians, able to walk at least 5 meters with/without gait aid and with ongoing walking or balance goals. Demographic and stroke characteristics, including stroke risk factors, infarct location and volume, leukoaraiosis on routine MRI, and acute stroke treatments (e.g., thrombectomy) will be determined and documented. A battery of impairment, psychosocial, and functional measures, including the mRS and Timed-Up and Go test (primary outcomes) will be completed. Subsequently, participants will be set up to wear activPAL accelerometer, validated in stroke, for 1 week. Following randomization, a sedentary behaviour change intervention will span 6 weeks, with final follow-up assessments at 90 days.
详细描述
Background Prolonged sedentary behaviour is associated with worse functional outcomes poststroke. The effect of reducing sedentary behaviour early after stroke remains unknown. Leukoaraiosis or cerebral white matter disease, recognizable on magnetic resonance imaging (MRI) as areas of hyperintensities, has gained significance as a potential moderator of stroke recovery. No specific rehabilitation intervention has been developed for survivors of stroke with leukoaraiosis.
The goals of this research project are to:
- Test the effect of reducing sedentary behaviour early after stroke on functional mobility and global disability outcomes.
- Determine the impact of leukoaraiosis on response to poststroke rehabilitation.
- Explore the associations of accelerometry metrics with functional mobility and global disability outcomes poststroke.
Methods The investigators aim to recruit 50 participants, within 3 months of stroke onset, aged ≥ 18 years, medically stable as deemed by physicians, able to walk at least 5 meters with/without gait aid, and ongoing walking goals (walk speed <1.0 meter/second). Demographic and stroke characteristics, including stroke risk factors, infarct location and volume, leukoaraiosis on MRI, and acute stroke treatments (e.g. thrombectomy) will be determined and documented. Subsequently, participants will be set up to wear activPAL accelerometer, validated in stroke,5 for one week. Following randomization, a behaviour change intervention will span 6 weeks with final follow-up assessments at 90 days.
Primary outcomes: modified Rankin Scale and Timed-Up and Go (TUG) score.

研究组 & 干预措施
Behaviour- & Imaging-Guided Stepping Training Early Post-Stroke (BIG STEPS)
Additional to usual care, the experimental arm will undergo a theory-based behaviour change intervention to improve stepping time relative to reducing sedentary behaviour.
