Table 2 Association between maximum Center of Pressure (CoP) movement for both AP and ML direction and continuously measured BP change 15 s before (n = 25), during (n = 38) and after (n = 36) after the maximum CoP movement

From: Blood pressure change does not associate with Center of Pressure movement after postural transition in geriatric outpatients

  1. BP systolic blood pressure, CoP center of pressure, AP anterior-posterior, ML medial-lateral
  2. p-values obtained with Spearman’s rho correlation analysis. Bonferroni adjusted p-value of .005 was statistically significant. Analyses were done in 15 s time periods
  3. aMaximum CoP movement
