Abstract: Objective To study the influence of center of gravity excursion in standing on function outcome of stroke patients.Methods46 stroke patients were assessed with static posturography in standing,Fugl-Meyer Balance Scale,Barthel Index and the time in hospital.The patients were divided into 2 groups according to posturography results:center of gravity was inclined to the normal side (normal group),center of gravity was inclined to the hemiplegia side (hemiplegia group).ResultsThe ability of balance,walking and activity of daily living(ADL)of the normal group patients were better than that of the hemiplegia group patients,and the in-hospital time was shorter (P<0.001).ConclusionThe center of gravity excursion in standing is highly correlated with functional outcome of stroke patients.

Key words: hemiplegia, stroke, gravity excursion, function, prognosis
