Popis: BACKGROUND: While over half of stroke survivors recover the ability to walk without assistance, deficits persist in the performance of walking adaptations necessary for safe mobility in the home and community. One such adaptation is the ability to walk or step backward. Post-stroke rehabilitation rarely includes assessment of backward walking (BW) and BW deficits have not been quantified in post-stroke community ambulators. OBJECTIVE: To quantify spatiotemporal and kinematic BW characteristics in post-stroke community ambulators and compare their performance to healthy older adults. METHODS: Individuals post-stroke (n=15, 60.1±12.9 years, forward speed: 1.13±0.23 m/s) and healthy adults (n=12, 61.2±16.2 years, forward speed: 1.40±0.13 m/s) performed forward walking (FW) and BW during a single session. Step characteristics and peak lower extremity joint angles were extracted using 3D motion analysis and analyzed with mixed-method ANOVAs (group, walking condition). RESULTS: The stroke group demonstrated greater reductions in speed, step length and cadence and a greater increase in double-support time during BW compared to FW (p
