TY - JOUR PY - 2003// TI - The effect of gait speed on lateral balance control during walking in healthy elderly JO - Gait and posture A1 - Helbostad, Jorunn L. A1 - Moe-Nilssen, R. SP - 27 EP - 36 VL - 18 IS - 2 N2 - The aim of this paper was to investigate the effect of speed dependency on lateral gait parameters. In 36 healthy elderly (mean age=72.5 years, S.D.=3.2 years), walking at four different self-administered speeds, mediolateral trunk acceleration and step width (SW), but not step-width variability (SWV), were found to have quadratic relations to gait speed. Normalizing for speed by curvilinear interpolation, and controlling for subject characteristics, disclosed smaller SW (adjusted R2=0.41, P<0.001), but larger SWV (adjusted R2=0.26, P=0.01) with increasing age in multiple regression models. These relations were camouflaged at preferred speed.
