title: Recovery process of standing postural control in hemiplegia after stroke.
abstract: [Purpose] The aim of this study was to investigate the recovery process of standing postural control in hemiplegia after stroke. [Subjects and Methods] Thirty-four inpatients with hemiparesis after first-onset stroke were included in this study. We measured the center of pressure fluctuations during quiet standing using a force platform at 2, 4, and 6 weeks after admission. We assessed weight-bearing asymmetry, and velocity and amplitude of body sway. [Results] Weight-bearing asymmetry diminished in the first 2 weeks of observation. Velocity of body sway also decreased significantly in the first 2 weeks, though its amplitude only decreased significantly after 4 weeks of observation. [Conclusion] Amplitude of body sway requires a longer time for significant improvement than weight-bearing asymmetry and velocity of body sway. Although the loading function of the paretic lower limb improved at an early stage, attainment of optimum postural control, including management of the affected paretic lower limb, requires much time.
