SIRRACT: An International Randomized Clinical Trial of Activity Feedback During Inpatient Stroke Rehabilitation Enabled by Wireless Sensing

Initiatives -
Our aim for this trial was to motivate patients and their therapists to engage in greater skills practice to obtain improved walking-related outcomes. We endeavored to demonstrate the feasibility of deploying sensors in inpatient rehabilitation centers regardless of culture, language, or familiarity with clinical research. Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.

Health Status
  • stroke of any type with residual hemiparesis,
Other criteria
Exclusion criteria included aphasia limiting the ability to follow 2-step commands and ongoing medical disease limiting participation in physical therapy. Patients who had suffered a prior stroke were eligible for participation if they had experienced full motor recovery.

Data Collection Event
In this phase III randomized, single blind clinical trial, patients participated in conventional therapies while wearing wireless sensors (tri-axial accelerometers) at both ankles. Activity-recognition algorithms calculated the speed, distance, and duration of walking bouts. Three times a week, therapists provided either feedback about performance on a 10-meter walk (speed-only) or walking speed feedback plus a review of walking activity recorded by the sensors (augmented).
