Fig 1 The degree of (A) pes equinus and (B) pes varus as the difference in average COP position between both feet in relation to the length and width of the BOS, respectively. Pes equinus=a−b/BOS length; pes varus=|a−b|/BOS width. Archives of Physical Medicine and Rehabilitation 2004 85, 886-895DOI: (10.1016/j.apmr.2003.05.012)

Fig 2 Postural stability, expressed as the RMS of the VCOP in (A) the frontal plane and (B) the sagittal plane for all stroke patients (N=37) during all follow-up assessments. NOTE. The 95% CIs are plotted 1-sided for visual clarity. Abbreviations: HE, healthy elderly (n=23); LAT, lateral; S, start of balance training.

Fig 3 Asymmetry in kinetic regulation activity, expressed as the RMS of the VCOP of the nonparetic leg divided by that of the paretic leg in both the frontal and sagittal planes for all stroke patients (N=37) during all follow-up assessments of the EO condition. NOTE. The 95% CIs are plotted 1-sided for visual clarity. Archives of Physical Medicine and Rehabilitation 2004 85, 886-895DOI: (10.1016/j.apmr.2003.05.012)

Fig 4 Asymmetry in weight bearing, expressed as the average lateral deviation in COP toward the nonparetic leg with respect to the BOS width, for all stroke patients (N=37) during all follow-up assessments. NOTE. The 95% CIs are plotted 1-sided. Archives of Physical Medicine and Rehabilitation 2004 85, 886-895DOI: (10.1016/j.apmr.2003.05.012)

Fig 5 The degree of (A) equinus loading and (B) varus loading on the paretic foot, expressed as the difference in average COP position between the feet with respect to the BOS length and width, respectively, for all stroke patients (N=37) during all follow-up assessments. NOTE. The 95% CIs are plotted 1-sided. Archives of Physical Medicine and Rehabilitation 2004 85, 886-895DOI: (10.1016/j.apmr.2003.05.012)

Fig 6 Equinus loading on the paretic foot, expressed as the difference in AP COP position between the feet with respect to the BOS length, for the stroke patients with initial Brunnstrom stage scores of I through IV (n=21) and for those with an initial Brunnstrom stage score of V or VI (n=16) during all follow-up assessments of the EO condition. NOTE. The 95% CIs are plotted 1-sided. Archives of Physical Medicine and Rehabilitation 2004 85, 886-895DOI: (10.1016/j.apmr.2003.05.012)
