Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 30–80 with chronic hemiparesis from stroke who walk slower than 1.0 m/s, can walk 10 m over ground and at least 5 minutes continuously on a treadmill, and can follow simple instructions.
✕Probably not a fit
People with recent cardiac or pulmonary hospitalization, implanted pacemakers/defibrillators, severe lower-limb hypertonia, unstable joints, or who cannot walk continuously for 5 minutes are unlikely to benefit or be eligible.

What this trial studies
This cross-sectional, single-session study enrolls adults with chronic hemiparetic stroke and walking impairment to test measurement properties of a novel biomechanical cost-of-walking metric. Participants complete three five-minute treadmill walking trials at a comfortable speed, with the third trial performed against added resistance to increase energetic cost. The biomechanical measure will be compared to metabolic cost and common functional tests to examine convergent validity, test-retest reliability, and responsiveness. The aim is to determine whether the biomechanical metric can pinpoint sources of movement inefficiency that underlie elevated energy costs after stroke.
Why it matters
Potential benefit: If successful, the measure could help clinicians identify the biomechanical sources of inefficient walking so therapy can target the right impairments and potentially improve independence.
How similar studies have gone: Metabolic cost-of-walking measures are well established, but this biomechanical decomposition approach is relatively novel and has limited prior validation.
