Abstract: 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. 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). 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). 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 in iduals would benefit from physical interventions aiming at improving the strength of the LE muscles, when the goal is to enhance participation.

Abstract: To assess the perception of patients with chronic hemiplegia regarding the use of assistive walking devices (AWD). Twenty-three in iduals who met the inclusion criteria and used AWD were recruited from a database of 360 stroke survivors. Their mean age was 58.4 years, mean time since stroke was 80.8 months, and mean time using AWD was 67.6 months. To assess the participants' perception, was used a standardized questionnaire covering the impact of AWDs on five aspects: weight-bearing on the paretic limb ability to move the paretic limb confidence safety and walking style. Possible answers were "improved," "unchanged," or "decreased." Fourteen in iduals used canes and nine used elbow crutches 21 (91.3%) used AWDs on public roads and only two (8.7%) used AWDs at home. The perception regarding the use of AWDs were positive in the first four questions (6.87 < χ2 < 29.83 0.0001 < P < 0.03), with reports of improvement in weight-bearing (82.6%), ability to move the paretic limb (39.1%), confidence (82.6%), and safety (86.9%). No significant differences were found in terms of walking style (χ2 = 1.09 P = 0.30). The perception of chronic hemiplegic subjects regarding the use of AWD were positive, suggesting that these devices can improve mobility and independence in activities of daily living.

Abstract: Abstract Introduction: According to studies from developed countries, post-stroke in iduals commonly have a low level of physical activity. Considering the benefits of maintaining a good level of physical activity in these subjects, it is important to provide specific and complete information, based on the assessment of all dimensions of physical activity, which supports interventions. Objective: To compare the physical activity levels between in iduals with stroke and matched healthy in iduals that use the public health system in Brazil considering the different dimensions of physical activity. Methods: In iduals with stroke (n = 11) and matched healthy in iduals (n = 11) were assessed. Physical activity levels, considering all dimensions -duration ( 3 MET), frequency (number of steps) and intensity (mean total energy expenditure per day) - were assessed using SenseWear® monitor for seven days. Descriptive statistics and between-groups comparisons were performed (α = 0.05). Results: The physical activity levels were significantly lower in in iduals with stroke when compared to matched healthy in iduals, considering all dimensions. The between-group differences in activity duration, frequency, and intensity were 74 minutes/day, 5,274 steps/day, and 2,134kJ/day, respectively. Conclusion: In iduals with stroke users of the Brazilian public health system have lower physical activity levels in different dimensions of physical activity than matched healthy in iduals. The assessment of the physical activity level of post-stroke in iduals is important for decision making in public health programs.

Abstract: O objetivo foi descrever e comparar diferenças na restrição na participação social de in íduos após acidente vascular encefálico (AVE) na fase crônica, considerando as deficiências, limitações em mobilidade e fatores pessoais. A restrição na participação social foi mensurada pelo LIFE-H 3.1-Brasil as deficiências pela Escala de Depressão Geriátrica e Escala de Fugl-Meyer (EFM) as limitações em mobilidade pela velocidade de marcha e Timed Up & Go (TUG) e os fatores pessoais incluíram sexo, idade, situação familiar e tempo de evolução pós-AVE. Observou-se restrição significativa na área de recreação. Em geral, restrições na participação social foram observadas em participantes com escores ≤28 na EFM-membro inferior, sintomas de depressão, marcha comunitária limitada, risco de quedas e tempo de evolução ≤5 anos. Aqueles com escores ≤45 na EFM-membro superior apresentaram maior restrição em algumas áreas das atividades diárias. As mulheres apresentaram maior restrição em papéis sociais. Os resultados sugerem que deficiências e limitações relacionadas aos membros inferiores, sintomas depressivos e tempo de evolução devem ser considerados na avaliação, quando o objetivo da reabilitação for aumentar a participação social de in íduos pós-AVE.

Abstract: There are robust clinical paradigms against the prescription of walking sticks for people with stroke. However, there is little information on the biomechanics of gait with and without these devices to guide clinical practice. Therefore, this study investigated how the use of walking sticks (canes or crutches) affected both the kinematics and kinetics of gait in people with chronic stroke after their walking had stabilized. Nineteen people with chronic stroke walked at both comfortable and fast speeds. A 3-D motion analysis system and one force platform were used to obtain kinematic and kinetic data of the paretic lower limb during four conditions: With and without walking sticks, and at comfortable and fast speeds. Outcomes included linear kinematics (walking speeds) and angular kinematics (maximum joint angles), power, and work of the paretic hip, knee and ankle joints in the saggital plane. The use of walking sticks resulted in increases in speed during both fast (P<0.001) and comfortable (P=0.001) walking, but did not result in changes in maximum joint angles. This also led to increases in ankle plantar flexion (P<0.01), knee extension (P<0.01), and hip flexion (P<0.001) power generation, but did not result in changes in work. There were no greater changes as a result of using walking sticks during fast versus comfortable walking for any outcome. INTERPRETATIN: The outcomes with the use of walking sticks were beneficial, which suggests that the prescription of these devices is not detrimental to walking that was stabilized in people with stroke.

Abstract: To determine the Duke Activity Status Index (DASI) cut-off scores and verify if they would be able to discriminate between chronic stroke in iduals, who had poor, from those who had good functional capacity (FC). Cross-sectional study, where 92 in iduals with chronic stroke had their FC measured by DASI scores and were classified into community and non-community walkers. Both the receiver operating characteristic and the area under the curve were used to determine the best DASI cut-off values that could discriminate between in iduals, who had poor, from those who had good FC. Binary logistic regression analysis is used to investigate the ability of DASI scores in predicting community walkers. DASI cut-off value of 31.95 showed to be sensitive and specific to differentiate between in iduals, who had poor from good FC. The regression analysis revealed that the chance of in iduals, who had better FC (≥ 31.95) be community walkers was 10.69 (95%CI:4-32.75) times higher than that of those who had poor FC (< 31.95). The model demonstrated good predictive ability. The DASI cut-off value of 31.95 showed to be sensitive and specific to distinguish between chronic stroke in iduals, who had poor, from those who had good FC.IMPLICATIONS FOR REHABILITATIONThe identification of in iduals, who have good and poor functional capacity, is important for clinical reasoning and decision-making in stroke rehabilitation.The Duke Activity Status Index (DASI) is a clinically useful tool for the assessment of functional capacity, based upon the performance of common daily living activities.The DASI cut-off of 31.95 points was able to discriminate between in iduals with stroke, who had poor, from those who had good functional capacity.The chance of in iduals, who had good functional capacity (DASI ≥ 31.95) be community walkers was 10.69 times higher than that of those who had poor functional capacity (DASI < 31.95).The findings support the use of the DASI as a simple tool for the assessment of functional capacity, especially in low-resource settings.

Abstract: The purpose of this study was to examine the relationships between isometric hand grip (HG) strength and isokinetic strength data of the glenoumeral and scapulothoracic muscles in 12 in iduals with chronic hemiparesis due to stroke. Measures of maximal grip strength were obtained on the HG dynamometer Jamar(®). Isokinetic measures of peak torque and work during shoulder rotations and scapular protraction-retraction movements were obtained with the isokinetic dynamometer at a speed of 60°/s. Pearson correlation coefficients between isometric HG and isokinetic strength data ranged between 0.60 and 0.82 for the peak torque and between 0.59 and 0.86 for the isokinetic work. The findings suggested that, in absence of isokinetic dynamometers, isometric HG strength measurements could be clinically used to monitor strength levels of the shoulder stabilizers and to guide load progressions during strengthening interventions for people with chronic hemiparesis.

Abstract: To investigate the concurrent validity of the Modified Sphygmomanometer Test (MST) with fixed stabilization, compared to the portable dynamometer, and to verify its test-retest and inter-raterreliability. Methodological study. The muscle strength of the following groups was measured: flexors and extensors of the wrist, of the hip, and of the knee and plantar flexors. The Tycos® aneroid sphygmomanometer and the Microfet 2® dynamometer were used. Stabilization was performed using the Mullingan® belt. Descriptive statistics were performed for characterization of the s le. To determine the validity of the MST with fixed stabilization, comparing it with the portable dynamometer, we investigated the correlation between the measurements obtained with the two instruments using the Pearson correlation coefficient. Intraclass Correlation Coefficient (ICC) was used to investigate inter-examiner and test-retest reliability (α = 0.05). 59 in iduals were included (1176 evaluations). A statistically significant correlation of moderate to high magnitude (0.58 ≤ r ≤ 0.81) was observed for concurrent validity of the MST with fixed stabilization versus the portable dynamometer for all muscle groups. Regarding inter-rater reliability, it was observed statistically significant ICC considered excellent to good (0.72 ≤ r ≤ 0.94) for all muscle groups. Regarding test-retest reliability, first evaluator presented good to excellent ICC (0.64 ≤ r ≤ 0.94), while second evaluator presented good to excellent ICC (0.74 ≤ r ≤ 0.96) for all muscle groups. The MST with fixed stabilization is valid and reliable for clinical measurement of muscle strength and can overcome previous limitations reported in the literature.

Abstract: 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. Cross-sectional study. Chronic stroke patients and healthy subjects. 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. Ninety-seven in iduals 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. 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.
