Hip abduction with ankle dorsiflexion (HAAD) score and trunk seating control within 72 h after stroke predicts long-term disability: A cohort study.

Background: The aim of this study was to determine whether muscle strength of the lower limb and trunk during the acute phase after stroke are predictors of motor function and disability 90 days after hospital discharge.

Methods: This prospective study used a nonconcurrent design to evaluate stroke patients at two time points: a) first 72 h: hip abduction and ankle dorsiflexion (HAAD) score, trunk sitting control, clinical evaluation, demographic profile, and stroke severity using the National Institutes of Health Stroke Scale (NIHSS); b) 90 days after hospital discharge: modified Rankin scale (mRS). The participants were divided into two groups: good outcome (mRS 0-2) and worse outcome (mRS>2), and the differences between them were assessed statistically.

Virtual Reality Immersion in Healthy Individuals: Ellipse Sway Area of an Electrical Shuttle Balance.

To assess indirectly the effects of virtual reality (VR) immersion on postural sway in thirteen healthy individuals. The ellipse sway area was recorded with an accelerometer coupled to an electrical shuttle balance under six conditions, varying Romberg and single leg stance (SLS) position with eyes open and eyes closed. The length of the ellipse traveled over 10 s was measured and Romberg and single leg stance (SLS) ratios were calculated.
