RESUMO
PURPOSE: To investigate the effects of inspiratory strength training on respiratory muscle strength, pulmonary function, and walking capacity in children with cerebral palsy, with Gross Motor Function Classification System I to III. METHODS: Searches were conducted in CINAHL, LILACS, MEDLINE, and Physiotherapy Evidence Database (PEDro) databases. The outcomes of interest were respiratory muscle strength, pulmonary function, and walking capacity. The quality was assessed by PEDro Scale. The Grading of Recommendations Assessment, Development, and Evaluation system was used to summarize the quality of evidence. RESULTS: Inspiratory strength training increased the strength of inspiratory muscles and may increase the strength of the expiratory muscles. No changes were observed in pulmonary function or walking capacity. CONCLUSIONS: This systematic review provides moderate-quality evidence that inspiratory strength training is effective for increasing inspiratory muscle strength in children with cerebral palsy. Benefits may be carried over to improving expiratory muscle strength but were not observed on pulmonary function or walking capacity.

The objective was to investigate, through a systematic review, which independent variables predict health-related quality of life (HRQoL) one year after stroke. Searches were conducted in LILACS, MEDLINE, Scielo, Web of Science, and PEDro. The inclusion criteria were observational longitudinal studies, which included at least one independent variable measured at baseline, as a potential predictor of HRQoL measured 12 months after stroke. The predictors of interest were variables across all domains of the International Classification of Function, Disability and Health. The quality of evidence was rated according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). A total of 17 papers were included, involving 8338 participants, and 10 possible predictors of the HRQoL one year after stroke. The meta-analysis was performed for six of them (cognition, depression, neurological deficit, stroke severity, motor impairment, and limitation in activities of daily living), and significant results were found only for limitation in activities of daily living (odds ratio, 1.30 [95% confidence interval, 1.09-1.57]; I2 â =â 72%; P â <â 0.01). The descriptive analysis of the remaining four predictors suggested a significant predictive value of balance and functional independence, whereas the results for trunk control were not significant and for social participation were unclear. In conclusion, individuals within the first 11.5 weeks after stroke with lower limitation in activities of daily living, higher functional independence, and better balance, are more likely to have a higher HRQoL one year after stroke. Thus, these predictors, all modifiable factors, need to be targeted during acute rehabilitation.

The objective was to examine the effects of backward walking training for improving walking speed and balance in children with cerebral palsy. A systematic review of randomized trials was conducted. Trials had to include children with cerebral palsy, with a Gross Motor Function Classification System, between I and III, that delivered backward walking training as a solo intervention or in combination with forward walking training. The outcomes of interest were walking speed and balance. The methodological quality of included trials was assessed by the PEDro scale, and the quality of evidence was assessed according to Grading of Recommendations Assessment, Development and Evaluation. Eight papers, involving 156 participants, were included. Using random-effects meta-analysis, we estimated that backward walking training improved walking speed by 0.10â m/s [95% confidence interval (CI) 0.05-0.16] and by 2 points on the Pediatric Balance Scale (0-56) (95% CI 1.5-2.2) more than forward walking training. We also estimated that the addition of backward walking training increased walking speed by 0.20â m/s (95% CI 0.07-0.34) and reduced the angular excursion of the center of gravity by 0.5 degrees (95% CI -0.7 to -0.3). The quality of the evidence was classified as low to moderate. In conclusion, overall, backward walking training appears to be as effective or slightly superior to forward walking training for improving walking speed in children with CP. The addition of backward walking training statistically significantly and clinically important enhanced benefits on walking speed.

OBJECTIVE: To explore the relationship between walking measurements (i.e., walking speed, walking performance and walking confidence), and participation in ambulatory people with chronic stroke. MATERIALS AND METHODS: Participation was measured using the mobility domain of Brazilian version of the Stroke Impact Scale 3.0. Walking measures were walking speed, assessed by 10-m Walk Test, walking performance, assessed by ABILOCO, walking confidence, assessed by mGES. Pearson correlation coefficients were used to explore the relationships between the walking measures and social participation, and step-wise multiple linear regression analysis was used to identify which walking measures would explain participation after stroke. RESULTS: Ninety-five chronic stroke individuals (38 men), with a mean age of 67 (SD 13) years were assessed. Significant positive correlations, of high magnitude, were found between participation and all walking measures (r ≥ .53; p < .001). Regarding the regression analysis, walking confidence alone explained 44% (F = 72.4; p < .001) of the variance in participation. When perceived locomotion ability was included in the model, the explained variance increased to 48% (F = 42.8; p < .001). CONCLUSION: All walking measures were correlated with social participation after stroke, but only perceived locomotion ability and walking confidence explained the variance in participation. Clinicians should be encouraged to evaluate real-life performance and personal factors that may limit community participation after stroke.

Identifying the determinants of walking confidence can be crucial in therapeutic terms. On these bases, interventions to improve these factors could improve, in turn, walking confidence. Objective is to explore the relationship between motor impairments and activity limitation measures and walking confidence in people with chronic stroke. Walking confidence was assessed using the modified Gait Efficacy Scale. The independent variables were: strength of the hip flexors and knee flexors/extensors (measured with a dynamometer), lower limb coordination (assessed by the Lower Extremity Motor Coordination Test), dynamic balance (assessed by the Four-Square Step Test), walking speed (from the 10-m Walk Test), aerobic capacity (from the 6-Minute Walk Test), and self-perceived locomotion ability (assessed by the ABILOCO). Pearson correlation was used to explore the relationships between the variables, and multiple linear regression to identify the independent explainers of walking confidence after stroke. Ninety chronic stroke individuals (35 men), with a mean age of 68 (SD 13) years were assessed. All independent variables were significantly correlated with walking confidence. Regarding the regression analysis, these measures explained 44% ( F = 9.21; P < 0.001) of the variance in walking confidence; however, only walking speed, strength of the hip flexor muscles, aerobic capacity, and perceived locomotion ability showed significance. All motor impairment and activity limitation measures correlated with walking confidence. However, the regression analysis highlighted that only walking speed, aerobic capacity, the strength of the hip flexor muscles, and perceived locomotion were independent explainers of walking confidence after stroke.

PURPOSE: To examine whether using a cane would improve spatiotemporal parameters of walking, i.e., speed, stride length, cadence, and symmetry after stroke. MATERIAL AND METHODS: Searches were conducted in eight databases. The experimental condition was walking with a cane. Four outcomes were of interest: walking speed, stride length, cadence, and symmetry. RESULTS: Twelve studies were included. Results from nine studies suggested that individuals with stroke walked 0.01 m/s (SD 0.06) slower with a single-point cane, compared with no cane. Two studies suggested a reduction in cadence (MD-5 steps/min, SD2) and an increase in stride length (MD 0.08 m, SD 0.01). Three studies suggested that individuals walked 0.06 m/s (SD 0.07) slower with a four-point cane, compared with no cane. Four studies suggested that individuals walked 0.06 m/s (SD 0.04) faster with a single- point cane compared with a four-point cane. Results regarding other outcomes were inconclusive. CONCLUSIONS: Results showed no worthwhile improvements in spatiotemporal parameters of walking with a single-point cane and a slight reduction with a four-point cane, compared with no cane. Individuals walked slightly faster with a single-point cane compared with a four-point cane, but the evidence is insufficient to support this superiority.IMPLICATIONS FOR REHABILITATIONA single-point cane may not improve spatiotemporal parameters of walking after stroke.Walking with a four-point cane may slightly decrease spatiotemporal parameters of walking.Canes may be prescribed without the fear of negatively impairing walking kinematics.

To validate the telephone-based application of the modified Gait Efficacy Scale (mGES) for the assessment of walking confidence in older people. Participants answered the mGES-Brazil on two randomized occasions, face-to-face and by telephone. The mean difference (MD) between the interviews was reported. Intraclass correlation coefficient (ICC3,1) was used to investigate the levels of agreement between the two occasions for total mGES-Brazil scores and for the individual items. A total of 78 individuals were included. There was no significant difference in the MD obtained between applications of the mGES (1 point, 95% confidence interval -6 to 7). A very high level of agreement was found between the mGES total scores during face-to-face and telephone applications (ICC = 0.98; 95% CI 0.97-0.99). All items, except one (item 3), had a very high agreement between the two applications. The mGES showed to be reliable to be applied for telephone assessments of walking confidence in older people.

The aim of the study was to validate the telephone-based application of the ABILOCO questionnaire for the assessment of locomotion ability after stroke. Individuals after stroke answered the ABILOCO-Brazil questionnaire on two randomized occasions, face-to-face and by telephone, 5-7 days apart. The mean difference between the interviews was reported. Intraclass correlation coefficient (ICC) was calculated to investigate the agreement between the total scores, and weighted-Kappa statistics to investigate the agreement between the individual items. A total of 92 individuals were included. There was no significant difference in the mean scores between face-to-face and telephone-based applications of the ABILOCO [mean difference 0.17 logits; 95% confidence interval (CI), -0.88 to 0.54]. A high level of agreement was found between the ABILOCO total scores obtained between both applications (ICC = 0.90; 95% CI, 0.84-0.93), and most of the individual items had, on average, moderate agreement. The ABILOCO showed to be a reliable questionnaire for telephone assessment of locomotion ability after stroke.

BACKGROUND AND PURPOSE: Telephone-based assessment may be a valuable and cost-effective approach to improve monitoring and follow-up assessments in patients and research participants. Telephone-based assessment may be of particular value during times when it is important to reduce in-person contract, such as during the Covid-19 pandemic. The purpose of this study was to investigate concurrent validity of the telephone-based administration of the ABILHAND for the assessment of manual ability in individuals with stroke. METHODS: Using a cross-sectional study design, participants with stroke were invited to answer the ABILHAND questionnaire on 2 randomized occasions, face to face and by telephone, 5 to 7 days apart. The mean difference (MD) between the interviews was calculated (95% confidence interval [95% CI]) to investigate the concurrent validity. Intraclass correlation (ICC) and weighted κ coefficients were used to investigate the agreement between face-to-face and telephone-based administration. RESULTS: One hundred two participants (50 men; mean age = 65 years, SD = 13 years) were included. No significant differences were observed between the mean scores obtained with face-to-face and telephone-based administration of the ABILHAND (MD = -0.06; 95% CI, -0.72 to 0.60). Very high agreement was found between face-to-face and telephone-based administration (ICC = 0.90; 95% CI, 0.85 to 0.93) on the ABILHAND total scores. Most of the individual items had moderate or substantial κ agreement. DISCUSSION AND CONCLUSIONS: Telephone-based administration of the ABILHAND is valid for the assessment of manual ability after stroke. Clinicians and researchers may use the ABILHAND for monitoring manual ability in persons with stroke and/or screening potential research participants.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A318).

The purpose of the present study was to examine the main characteristics of clinical trials in physiotherapy aimed at improving walking speed after stroke, as well as the correlation between trials' methodological quality and journals' Impact Factor. Searches were conducted on Physiotherapy Evidence Database for all randomized controlled trials aiming at improving walking speed after stroke. Data extracted from the studies were: continent, language, methodological quality, year of publication, number of normalized citations, open access, sample size, measurements of walking speed, interventions, comparators, and prior registration. Data extracted from the journals were: 2018 Impact Factor, open access, endorsement of CONSORT recommendations, predatory classification, PubMed indexing, and Journal Citation Reports category. The main outcomes were journals' Impact Factor, open access, CONSORT recommendations endorsement by the journal, and methodological quality. Spearman correlation coefficients were calculated to explore the relationships between trials' methodological quality and journals' Impact Factor. Two hundred twenty-seven trials were published in 62 journals. The number of trials has increased over the last years. Most of these trials had citations, moderate methodological quality, were published in English, in open access journals, which endorse the CONSORT recommendations, and had Impact Factor ≥2.0. The results indicated a positive, but weak correlation between methodological quality and journals' Impact Factor. Thus, trials in physiotherapy aimed at improving walking speed after stroke have increased over the last years. Overall, trials had moderate methodological quality and were published in journal with moderate-to-high Impact Factor. Best trials were not necessarily published in journals with high Impact Factor.

BACKGROUND: Water-based exercises have the potential to reduce impairments and walking limitations after stroke. OBJECTIVE: To examine the effects of water-based exercises on walking speed, balance, and strength after stroke. DATA SOURCES: Eletronic searches on MEDLINE, CINAHL, EMBASE, Cochrane, PsycINFO, and PEDro databases. ELIGIBILITY CRITERIA: The review included randomized trials. Participants in the reviewed studies were ambulatory adults, who have had a stroke. The experimental intervention was comprised of water-based exercises. DATA SYNTHESIS: Outcome data related to walking speed, balance, and strength were extracted from the eligible trials and combined in meta-analyses. The quality of the included trials was assessed by the PEDro scores and the quality of evidence was determined according to the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS: Thirteen trials involving 464 participants were included. Random-effects meta-analyses provided moderate-quality evidence that water-based exercises significantly increase walking speed by 0.06m/second (95% CI 0.01 to 0.10) and balance by 4.5 points on the Berg Balance scale (95% CI 2.2 to 6.8), compared with land-based exercises, without concurrent changes in strength (MD 5.2Nm/kg; 95% CI -1.4 to 11.9). CONCLUSIONS: This systematic review provided low-quality evidence regarding the efficacy of water-based exercises, compared with no intervention. However, there is moderate quality evidence, which suggested significant benefits of water-based exercises in walking speed and balance, compared with land-based exercises. Differences appear small to be considered clinically relevant, and, therefore, water-based exercises can be prescribed as alternative interventions, based upon individuals' exercise preferences. Systematic Review Registration Number PROSPERO (CRD42018108419).

The objective of the present study was to investigate if different levels of inspiratory muscle strength would be associated with dyspnea, walking capacity, and quality of life after stroke. For this exploratory study, the dependent outcome was strength of the inspiratory muscles, measured by maximal inspiratory pressure. Individuals with maximal inspiratory pressure ≥80 cmH2O were classified as non-weak, those with maximal inspiratory pressure between 45 and 80 cmH2O were classified as weak, and those with maximal inspiratory pressure ≤45 cmH2O were classified as very weak. Related outcomes included dyspnea, measured by the modified Medical Research Council scale; walking capacity, measured by the 6-minute walk test; and quality of life, measured by the Stroke-Specific Quality of Life scale. Fifty-three participants, who had a mean age of 62 years (SD 12) and a mean time since the onset of the stroke of 20 (SD 17) months were included. Significant differences were found only between the weak/very weak and non-weak groups. The mean differences between the non-weak and weak/very weak participants were -1.8 points (95% confidence interval -2.7 to -0.9) for dyspnea and 55 points (95% confidence interval 22-88) for quality of life. Significant correlations were found between measures of inspiratory strength and dyspnea (r = -0.54; P < 0.01) and quality of life (r = 0.56; P < 0.01). There were not found any significant differences or correlations regarding walking capacity. The findings demonstrated that individuals with stroke, who had weakness of the inspiratory muscles, reported greater dyspnea and worse quality of life, compared with those, who did not have weakness. The results regarding walking capacity remain unclear.

BACKGROUND: The ABILOCO is a self-reported questionnaire, specific for individuals with stroke, for the assessment of ability of locomotion. The ABILOCO has been investigated using the Rasch model and has shown satisfactory measurement properties. However, its test-retest reliability has not been investigated. OBJECTIVE: To investigate the test-retest reliability, that is, agreement, systematic and random variability of the ABILOCO Questionnaire in individuals with chronic stroke. DESIGN: A test-retest reliability study. SETTING: Research laboratory. PARTICIPANTS: Thirty-one individuals (21 men and 10 women; mean age, 60 years), who had poststroke hemiparesis. INTERVENTION: Not applicable. MAIN OUTCOME MEASUREMENT: The ABILOCO was applied twice, on two occasions, 5 to 7 days apart. Test-retest reliability was investigated, as follows: agreement by the calculation of intraclass correlation coefficients (ICCs); systematic variability by the change in the mean; random variability by the standard error of measurement (SEM) and smallest real difference (SRD). RESULTS: Two outliers were identified in the sample. The ICC values for the whole sample were 0.76 (CI 95% 0.56 to 0.88), whereas the SEM (SEM%) and SRD (SRD%) were 0.55 (21%) and 1.52 (58%), respectively. CONCLUSION: The ABILOCO showed to be reliable to be applied within clinical and research contexts for the assessment of changes in locomotion ability of a group of individuals with chronic stroke. However, it appears to be less suitable to detect changes at individual levels. LEVEL OF EVIDENCE: III.

BACKGROUND: The identification of the predictors of locomotion ability could help professionals select variables to be considered during clinical evaluations and interventions. OBJECTIVE: To investigate which impairment measures would best predict locomotion ability in people with chronic stroke. METHODS: 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. RESULTS: Age, sex, and time since stroke did not significantly correlate with the ABILOCO scores (-0.07<ρ<0.05; 0.48

OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

BACKGROUND: Canes are usually prescribed for individuals with stroke with the purpose of improving walking and increasing safety. However, there is no consensus regarding the clinical effects of these aids on walking and participation. OBJECTIVE: This study will examine the efficacy of the provision of a cane to improve walking and increase participation after stroke. METHODS: This is a two-arm, prospectively registered, randomized trial with concealed allocation, blinded measurers, and intention-to-treat analysis. Fifty individuals with chronic stroke, categorized as slow or intermediate walkers (walking speeds ≤0.8m/s), will participate. The experimental group will receive a single-point cane and instructions to use the cane anytime they need to walk. The control group will receive a placebo intervention, consisting of self-stretching exercises of the lower limb muscles and instructions to not use assistive devices. The primary outcome will be comfortable walking speed. Secondary outcomes will include walking step length, walking cadence, walking capacity, walking confidence, and participation. Outcomes will be collected by a researcher blinded to group allocation at baseline (Week 0), after intervention (Week 4), and one month beyond intervention (Week 8). CONCLUSION: The provision of a single-point cane may help improving walking of slow and intermediate walkers after stroke. If walking is enhanced, the benefits may be carried over to participation, and individuals may experience greater free-living physical activity at home and in the community.

OBJECTIVES: To establish the deficits of motor coordination of the lower limbs after stroke, in comparison with healthy controls, and to investigate whether the magnitude of the deficits would be influenced by the levels of motor recovery. DESIGN: Cross-sectional study. SUBJECTS: Chronic stroke patients and healthy subjects. METHODS: Lower-limb motor coordination of both stroke and healthy volunteers was measured using the Lower Extremity Motor Coordination Test (LEMOCOT). The motor coordination deficits of the participants with stroke were analysed all together and separated, according to their levels of motor recovery, measured using the Fugl-Meyer lower-limb motor section scores. RESULTS: Ninety-seven individuals with chronic stroke, 55 men, mean age 58 years, were evaluated. Motor coordination was significantly impaired on both paretic (mean: -22 touches; 95% confidence interval (95% CI) -24 to -19; deficit: 61%) and non-paretic (mean -6 touches; 95% CI -8 to -4; deficit: 17%) lower limbs. Significant differences in the LEMOCOT scores were found between the levels of motor recovery (p < 0.01), except between the participants with marked and moderate impairments. CONCLUSION: Motor coordination of the lower limbs is significantly impaired after stroke, but the deficits of the non-paretic lower limb (17%) appear not to be clinically relevant. These findings suggest that interventions prescribed to improve motor coordination after stroke should focus on the paretic lower limb and/or include bilateral activities.

PURPOSE: To evaluate which measures of physical impairments of both upper extremity (UE) and lower extremity (LE) would predict restrictions in participation with 105 community-dwelling stroke subjects. METHODS: For this cross-sectional, exploratory study, participation was assessed by the daily activity and social role domains of the Assessment of Life Habits (LIFE-H). The potential predictors included measures of physical impairments (UE and LE motor recovery, sensation, motor coordination, and strength deficits). RESULTS: Step-wise multiple linear regression analyses revealed that, for the daily activity domain, LE strength deficits and UE motor recovery explained 28% of the variance in the LIFE-H scores and LE strength deficits alone explained 22% (F = 29.5; p< .0001). For the social role domain, LE strength deficits and sensation explained 22% of the variance in the LIFE-H scores and LE strength deficits alone explained 16% (F = 20.6; p< .0001). CONCLUSIONS: Strength deficits of the LE muscles were the physical impairment variables that best predicted participation in both daily activity and social role domains of the LIFE-H. Although significant, UE motor recovery and LE sensation added little to the explained variance. Future research is needed to determine whether progressive resistance strength training program enhances participation after stroke. Implications for Rehabilitation Residual strength deficits of the LE muscles were the physical impairments that showed to be the main predictors of restrictions in participation, as determined by the daily activity and social role domains of the LIFE-H 3.1. It is possible that stroke individuals would benefit from physical interventions aiming at improving the strength of the LE muscles, when the goal is to enhance participation.
