To investigate the test–retest reliability and measurement error of the Brazilian version of the modified Gait Efficacy scale (mGES-Brazil) in individuals who have had stroke. The mGES-Brazil was applied on two occasions, five to seven days apart, in a research laboratory setting. Test–retest reliability and measurement error, which included the standard error of measurement (SEM), smallest detectable change (SDC), and analysis of the limits of agreement by the Bland–Altman plots, were examined. Fifty individuals who have had stroke (18 men), with a mean age of 64 ± 11 years, were evaluated. All individual items showed good reliability (Intra-class Correlation Coefficient – ICC2,1 > 0.90). The ICC was 0.98 (95% CI 0.97 to 0.99) and the Bland and Altman plots revealed no systematic changes in the mean test–retest scores. The SEM (SEM%) was 3 (5%), within the recommended values, while the SDC was 8 points. The mGES-Brazil demonstrated to be reliable to be applied within clinical and research contexts for the assessment of changes in walking confidence of individuals who have had stroke. Changes in mGES scores ≥8 points reflect real changes. [ABSTRACT FROM AUTHOR]

Objective: To explore the relationships between selected measures of motor impairments and activities involving the lower-limbs in ambulatory people with chronic stroke. Design: Motor impairment measures included maximal isometric strength and motor coordination. Activity measures included walking speed, stair ascent/descent cadences, and the time to perform the Timed Up and Go (TUG) test. Results: Ninety individuals were included. The correlations between all motor impairment and activity measures were significant (0.18 < r < 0.52, p < 0.05). Motor coordination and strength of the knee flexor muscles explained 30% (F = 20.3; p < 0.001) of the variance in walking speed, 32% (F = 19.1; p < 0.001) of stair ascent, and 31% (F = 16.8; p < 0.001) of stair descent cadence. Regarding the TUG, only motor coordination reached significance and explained 13% (F = 13.4; p < 0.001) of the variance. Conclusion: Measures of strength and motor coordination of the paretic lower limb were significantly correlated with all activity measures. However, despite the fact that knee flexor strength explained some variance in walking speed and stair ascent/descent cadences, motor coordination was the only measure that explained the variances in all three selected activity measures. These findings are innovative for neurological rehabilitation, since this is the first study to demonstrate that deficits in motor coordination of the paretic lower limb best explained limitations in performing different lower-limb activities.

• Impairment and activity measures were significantly correlated with ability of locomotion. • Walking speed explained 35% of the variance in the ABILOCO scores. • Locomotion ability may increase if attention is focused on increasing walking speed. The identification of the predictors of locomotion ability could help professionals select variables to be considered during clinical evaluations and interventions. To investigate which impairment measures would best predict locomotion ability in people with chronic stroke. Individuals (n = 115) with a chronic stroke were assessed. Predictors were characteristics of the participants (i.e. age, sex, and time since stroke), motor impairments (i.e. muscle tonus, strength, and motor coordination), and activity limitation (i.e. walking speed). The outcome of interest was the ABILOCO scores, a self-reported questionnaire for the assessment of locomotion ability, designed specifically for individuals who have suffered a stroke. Age, sex, and time since stroke did not significantly correlate with the ABILOCO scores (−0.07 < ρ < 0.05; 0.48 < p < 0.99). Measures of motor impairments and walking speed were significantly correlated with the ABILOCO scores (−0.25 < r < 0.57; p < 0.001), but only walking speed and strength were kept in the regression model. Walking speed alone explained 35% (F = 55.5; p < 0.001) of the variance in self-reported locomotion ability. When strength was included in the model, the explained variance increased to 37% (F = 31.4; p < 0.001). Walking speed and lower limb strength best predicted locomotion ability as perceived by individuals who have suffered a stroke. [ABSTRACT FROM AUTHOR]

• The prevalence of dyspnea after a stroke was 44%. • Dyspnea is associated with activity limitations and restrictions in community participation after a stroke. • Stroke survivors, who had dyspnea, were six times more likely to report activity limitations and two times more likely to report restrictions in social participation. Dyspnea is a relevant outcome to be taken into consideration during stroke rehabilitation. Prevalence, severity, and effects of this condition on individuals with stroke remain uncertain. This study investigated the prevalence and severity of dyspnea after a stroke, as well the associations between dyspnea, activity limitations, and participation restrictions. A telephone-based survey was conducted with 285 individuals with stroke. The survey included information regarding the onset and severity of the dyspnea, activity limitations, and participation restrictions. Prevalence of dyspnea was reported as percentage of individuals who had the symptom. Chi-square tests were used to investigate the associations between dyspnea, activity limitations, and participation restrictions. Relative risks and respective 95% confidence intervals were calculated. Out of the 285 participants, 124 (44%) reported having dyspnea after stroke. Severe symptoms were reported by 51% of the participants with dyspnea. In addition, dyspnea limited activity and restricted social participation in 85% and 49% of the participants, respectively. Dyspnea was significantly correlated with activity limitations (r = 0.87; 95% CI 0.82–0.92; p < 0.01) and participation restrictions (r = 0.53; 95% CI 0.46–0.62; p < 0.01). The analyses indicated that individuals with dyspnea were more likely to report that it limited their activities (RR: 6.5; 95% CI 4.3–9.9) and restricted social participation (RR: 1.7; 95% CI 1.5–2.0). Dyspnea is an important symptom after stroke and showed to be associated with activity limitations and restrictions in community participation. Earlier detection of dyspnea in people with stroke, followed by appropriate management, is strongly recommended and has the potential to improve activity and social participation.
