Abstract
Bilateral postural sway measurements were made for 15 stroke patients (8 men and 7 women) aged 41 to 78 years, from 5 to 42 weeks after they sustained their first stroke. From the measured foot-ground reaction forces, biomechanical parameters were defined, including total sway activity, asymmetry, and relative sequence of the tangential forces. These parameters were correlated to the patients’ clinical data. The results determine the conditions and extent to which these mechanical parameters can be used as indicators for monitoring and prognosis of the locomotor functional outcome of stroke patients.
