Self-selected walking speed effectively stratifies stroke survivors into functional groups, correlating with daily step counts. Percentage of paretic preswing (PPS) significantly differs across all speed categories.

Area of Science:

  • Rehabilitation Medicine
  • Biomechanics
  • Clinical Gait Analysis

Background:

  • Self-selected walking speed is a common metric in stroke rehabilitation for stratifying patients.
  • Current stratification relies heavily on self-report, lacking objective validation.
  • Objective measures are needed to confirm the utility of speed-based classification.

Purpose of the Study:

  • To validate the existing speed-based classification system using objective walking performance measures.
  • To correlate self-selected gait speed with quantitative spatiotemporal, kinetic, and functional mobility data.
  • To determine if quantitative measures can reliably differentiate functional walking groups post-stroke.

Main Methods:

  • 59 individuals with post-stroke hemiparesis were assessed.

Asymmetric Walkway: A Novel Behavioral Assay for Studying Asymmetric Locomotion

  • Quantitative measures included paretic leg propulsion (Pp), paretic step length ratio (PSR), and paretic preswing percentage (PPS).
  • Daily steps/day and Fugl-Meyer Assessment synergy scores were also recorded; participants stratified into household, limited community, and community ambulators based on gait speed.

    • Main Results:

    • Significant main effects were observed across most gait measures.
    • Daily steps/day and PPS showed significant differences among all three speed-stratified groups.
    • Paretic propulsion (Pp) differentiated moderate from fast ambulators.

    Conclusions:

    • Stratifying individuals post-stroke by self-selected walking speed aligns with objective measures of daily walking behavior (steps/day).
    • Paretic preswing percentage (PPS) effectively distinguishes all three functional walking speed groups.
    • Speed-based classification is a practical tool for stratifying stroke survivors, with potential mechanical links to PPS and propulsion.
