Objective
To describe gait characteristics of patients without clinical evidence of lower limb hypertonia within 2 months of stroke and explore the relationship between gait and residual motor function. Design Cohort study. Setting Motion analysis laboratory in a tertiary-care free-standing rehabilitation hospital. Participants Consecutive sample of 73 eligible inpatients (first-known stroke Interventions Not applicable. Main Outcome Measures Gait speed, stride and step lengths and cadences, stance time, single-support and double-support times, and associated symmetry measures in patients at self-selected normal speed and controls at very slow speed (51.1±32.6 cm/s and 61.9±21.8 cm/s, respectively, P=.115); Fugl-Meyer lower extremity motor score (FM-LE) and isometric knee flexion and extension strength in patients. Results Except the stride/step cadence, all temporospatial parameters significantly differed between the stroke and control participants. Furthermore, significantly greater asymmetries were found in the patients for the overall stance time, initial double-support and single-support times, and step cadence, reflecting smaller values in the paretic than nonparetic limb. Most temporospatial parameters moderately to strongly correlated with the gait speed (|r|: .72-.94, P<.0001 fm-le .42-.62 p and paretic knee flexor strength .47-.57> Conclusions Gait of patients without clinical evidence of lower limb hypertonia within 2 months of stroke is characterized by many temporospatial deviations and asymmetries. The self-selected normal gait speed, FM-LE, and paretic knee flexor strength can discriminate gait impairments in these patients shortly before inpatient discharge. It remains to be determined whether the observed relationships between paretic knee flexor strength and gait measures warrant the development of interventions for strengthening of the paretic knee flexors in order to improve gait early poststroke. |
