Background Stroke rehabilitation is a complex intervention.
Many factors influence the interaction between the patient
and the elements of the intervention. Rehabilitation interventions are aimed at altering different domains of patient
outcome including body functions, activity and participation.
As a consequence, randomised clinical trials in this area
are difficult to design. We developed an archive of stroke
rehabilitation trials (VISTA-Rehab) to act as a resource to help
trialists model and design future rehabilitation studies.
Methods We developed specific eligibility criteria for the
entry of stroke rehabilitation trials into the archive. We
established a Steering Committee to oversee projects and
publications and commenced the recruitment of rehabilitation
trials into this resource.
Results As of August 2009, VISTA-Rehab contains data from
23 stroke rehabilitation trials (43400 patients). Demographic
data, including age [median573, interquartile range (63,79)],
gender (male553%)and initial dependency [medianbaseline
Barthel index score56, interquartile range (9,19)], are available
for all patients. Outcome measures include the modified
Rankin Scale, Barthel Index, Rivermead Motor Assessment,
Fugl-Meyer Assessment, General Health Questionnaire and
Nottingham Extended Activities of Daily Living Scale.
Conclusion VISTA-Rehab expands the Virtual International
Stroke Trials Archive to include rehabilitation trials. Anonymised data can be used to examine questions specific to
stroke rehabilitation and to generate novel hypothese
