Locomotor coordination during the sit-to-walk transfer is different in subjects with stroke and controls
(English)Manuscript (preprint) (Other academic)
Objectives: To describe and to compare coordination of centre of mass (COM) horizontal and vertical momenta, and fluidity during the sit-to-walk (STW) transfer in subjects with stroke and in matched controls.
Setting: Research laboratory.
Participants: Ten subjects with stroke in the post-acute phase (> 6 months) and ten control subjects, matched for sex, age, height and weight, were recruited through a convenience sample.
Interventions: Not applicable.
Main Outcome Measures: Magnitudes and timing of COM peak horizontal and peak vertical momenta, scores on the Fluidity Scale (FS) and values of the Fluidity Index (FI).
Results: The stroke subjects generated significantly less COM peak horizontal and peak vertical momenta. Latencies from STW-onset and seat-off to the peaks differed significantly between the two groups. The subjects with stroke displayed significantly lower scores on the FS as well as lower percentages of the FI.
Conclusions: While rising to walk, scaling and timing parameters of COM horizontal and vertical momenta differed significantly between subjects with stroke and matched controls. This atypical motor strategy needs to be further investigated before it is possible to make clinical recommendations.
