Assessment of dynamic balancing responses following perturbations during slow walking in relation to clinical outcome measures for high-functioning post-stroke subjects

You have to ask yourself why leave out the vast majority of stroke patients that are not high-functioning. This is cherry picking to the extreme, so the results are basically useless.

Abstract: 

Study assessed dynamic balancing responses following pushes to the pelvis in groups of post-stroke and healthy subjects. Forty-one post-stroke subjects and forty-three healthy subjects participated in the study. Dynamic balancing responses to perturbations triggered at heel strike of the left or right leg, directed in the forward, backward, inward and outward directions during slow treadmill walking were assessed. Responses of the healthy group provided reference values used to classify responses of the post-stroke group into two subgroups; one within the reference responses (inside subgroup) and the other that falls out (outside subgroup). A battery of selected clinical outcome measures (6-Minute Walk Test, 10-Meter Walk Test, Timed-Up-and-Go test, Four Square Step Test, Functional Gait Assessment, Functional Independence Measure, and one-legged stance test) was additionally assessed in the post-stroke group. The inside subgroup of post-stroke subjects was able to appropriately modulate center of pressure (CoP) and ground reaction force (GRF) both under the impaired and non-impaired leg in response to perturbations. The outside subgroup of post-stroke subjects showed limited modulation of CoP and GRF under the impaired leg; instead stepping strategy was used in which the non-impaired leg was placed such as to make a longer step (forward perturbation), to make a shorter step (backward perturbation) or to make a cross-step (outward perturbation). Consequently, peak center-of-mass (CoM) displacements following perturbations were significantly higher in the “outside” subgroup compared to the “inside” subgroup. Responses in both subgroups following inward perturbations did not differ. Majority of clinical outcome measures moderately correlated with the peak CoM displacements for forward perturbations and exhibited weak correlations for other perturbation directions.
