Dataset: Stroke Initiative for Gait Data Evaluation (STRIDE)
|Dataset Full Name||Stroke Initiative for Gait Data Evaluation|
The Stroke Initiative for Gait Data Evaluation (STRIDE) is an initiative based at the University of Southern California to create an inter-institutional, public database containing de-identified demographic and kinematic, kinetic, and spatiotemporal measures assessed via gait analysis in individuals post-stroke, to provide a larger and more heterogeneous research dataset than that typically amassed at a single institution. The purpose of the study was to understand how persons post-stroke generate symmetric steps and how the resulting gait pattern relates to the metabolic cost of transport. Data was collected at the following institutions: Johns Hopkins University, University of Southern California, University of Pittsburgh and Emory University.
55 persons post-stroke walked on an instrumented treadmill under two conditions: preferred walking and symmetric stepping (using visual feedback). Kinematic and kinetic data was collected during both conditions via three-dimensional motion capture, as well as metabolic data.

|Measures/Outcomes of Interest|
Walking stride, Gait, Treadmill, Motion capture, Kinematic (100 Hz) and kinetic (1000 Hz) data, three-dimensional motion capture, Visual3D, Metabolic cost of transport
Survivors of a first, unilateral stroke between 18 and 90 years of age across the United States who are able to walk on a treadmill for more than 2 minutes
|Unit of Observation||
Data collected at the following locations:
Data files broken down by location (see above)
|Data Collection Mode||
|Data Collection Frequency||
|Strengths and Limitations|
Extensive motion capture time series data available for each subject's step. Consistent "Core" of data collected across all 4 sites.
Limited documentation. Variation in content by location - some include additional data files that others don't have. Single participant data are presented in individual folders. Each participant's data broken into separate limb measures - up to 15 datafiles per individual.
|Data Access Requirements||
Data Use agreement, No cost

Stroke focused studies:
Johns Hopkins University data:
Persons post-stroke restore step length symmetry by walking asymmetrically
University of Pittsburgh data:
Self-selected step length asymmetry is not explained by energy cost minimization in individuals with chronic stroke.
Cerebral Contribution to the Execution, But Not Recalibration, of Motor Commands in a Novel Walking Environment
Augmenting propulsion demands during split-belt walking increases locomotor adaptation of asymmetric step lengths
University of Southern California data:
Using biofeedback to reduce spatiotemporal asymmetry impairs dynamic balance in people post-stroke
Individual Differences in Locomotor Function Predict the Capacity to Reduce Asymmetry
