Description
Summary:•Lower limb and trunk muscle strength are associated with comfortable/maximum gait speed in patients with sub-acute stroke.•Non-paretic dorsiflexors and left trunk lateral flexors predict comfortable/maximum gait speed in sub-acute stroke.•The effects of strengthening in these muscles on post-stroke gait speed need more investigation. To investigate the association between measures of strength of the lower limb and trunk muscles and gait speed and to identify the muscle group that would best predict gait speed in individuals with sub-acute stroke. Using a cross-sectional observational study design, forty-four individuals with sub-acute stroke (62 years, SD=14; 4 months, SD=1 post-stroke) were assessed. The evaluations were performed at a university laboratory, participants’ homes, or community-based settings. Bilateral maximum isometric strength (hip, knee, and ankle flexors/extensors, hip abductors, trunk flexors/extensors, and trunk lateral flexors and rotators) was measured using a portable dynamometer. Comfortable and maximum gait speeds were measured using the 10-m walk test. Weak to moderate associations were found between measures of strength of the lower limb muscles and comfortable (0.36≤r≤0.53; p
