RESUMO

BACKGROUND: Aquatic exercises are among the treatments available to improve the quality of life after stroke. OBJECTIVES: To investigate changes in the quality of life after 8-week of aquatic exercises in post-stroke individuals. METHODS: A case series study was designed, including four male participants. Exclusive aquatic exercise was performed for 8-week, 50 minutes per session, 2×/week. Their quality of life was evaluated before and after the intervention using the Stroke Impact Scale (SIS). RESULTS: Participant 1 improved in the mobility domain, achieving a Clinically Important Difference (CID). Participant 2 improved in the strength and mobility domain, achieving CID; his stroke recovery was 6%, and it reached 50% post-intervention. Participant 3 improved in the mobility domain, achieving a CID and a Minimal Detectable Change (MDC); his stroke recovery increased from 45 to 60% post-intervention. Participant 4 improved the strength, mobility, and activities of daily living domains, achieving a CID and a MDC, but his stroke recovery remained unchanged at 80%. CONCLUSIONS: All participants achieved a CID in the mobility domain; thus, the aquatic exercise intervention was considered meaningful. Moreover, the SIS is able to evaluate aspects of the recovery process regarding health-related quality of life after stroke, as demonstrated by the results of the overall recovery after aquatic exercises.

RESUMO

BACKGROUND: Surface electromyography (sEMG) can provide information on muscle activation patterns during gait. OBJECTIVES: To characterize electromyographic activity during gait in shallow water and during deep-water running compare to on land and to review and analyse underwater surface-electromyographic (sEMG) procedures. SEARCH METHODS: Eight databases (MEDLINE, EMBASE, WEB OF SCIENCE, SPORT Discus, CINAHL, SCOPUS, SCIELO, and LILACS) were searched from their inception to the December of 2019. SELECTION CRITERIA: The selected studies had to be related to electromyographic analysis of gait in an aquatic environment. DATA COLLECTION AND ANALYSIS: The studies that met the inclusion criteria were reviewed by two independent reviewers and divided into four groups. RESULTS: Ten studies met the inclusion criteria. Lower muscle activation was found with treadmill water walking compared to treadmill land walking. With deep-water running, the leg muscles (tibialis anterior and gastrocnemius lateralis) have lower muscle activation when compared to on land running, but the trunk and thigh muscles have higher activation. CONCLUSION: If gait is performed on an aquatic treadmill, the muscles assessed had lower muscle activation when compared to land. During deep-water running activities, lower activation of the distal leg muscles and a higher activation thigh muscles were found when compared to on land. Studies did not follow standard processes in sEMG procedures.

RESUMO

The Low Back Activity Confidence Scale (LoBACS) assesses the self-efficacy to perform activities in individuals with chronic low back pain (CLBP). As self-efficacy appears to directly influence the patient's functional capacity and prognosis, it is important to develop a scale that evaluates this attribute to guide treatment strategy and monitor the clinical course of patients. This study aimed to evaluate the reliability, construct validity, and responsiveness of the Brazilian version of the LoBACS. The scale was applied to 112 male and female patients (age, 18-65 years) with specific and nonspecific CLBP. For evaluating the interobserver reliability, the scale was applied twice on the first evaluation day by two trained evaluators (A and B). Within 48-72 h of the first evaluation, assessor A reapplied the scale to evaluate intraobserver reliability (test-retest), which was analyzed by intraclass correlation coefficient (ICC). The first LoBACS applied in the baseline evaluation was also used to assess the construct validity of the scale by factor analysis. For responsiveness, the scale was applied 5 times at 2-week intervals and the change in scores was analyzed by the repeated measures ANOVA. Although factor analysis indicated three subscales, they did not present acceptable values of convergent and divergent validity. Reliability ranged from good to excellent, with ICC values of .90 (95% CI, .84; .93) and .85 (95% CI, .77; .91) for inter- and intraobserver variability for total score. Moreover, the total score was responsive in all comparisons, with no floor or ceiling effects. Thus, only the total score of the Brazilian version of LoBACS proved to be reliable, valid, and responsive.

RESUMO

OBJECTIVE: The aims of this study were to evaluate the center of pressure (CoP) in individuals with chronic low back pain (LBP) compared with matched controls and perform discriminant analysis to detect which CoP variables differentiate the groups. METHODS: Thirty-two participants with LBP and 33 matched controls were evaluated on a force plate in a bipedal static position for 30 seconds in 2 conditions: eyes open (EO) and eyes closed (EC). Two discriminant analyzes were performed to detect which CoP variables could discriminate between groups. RESULTS: Those with LBP had higher values (ie, poorer balance) for most variables compared with the control group. With EO, total displacement of sway (TDS) was as follows: LBP group (median [25%-75%]) 31.77 (26.39-41.79) cm, control group 27.21 (22.29-31.78) cm, P = .008 and area: LBP group 3.31 (2.33-4.68) cm2, control group 1.77 (1.3-2.71) cm2. With EC, TDS was as follows: LBP group 49.6 (39.65-68.15) cm, control group 38.77 (30.36; 45.65) cm, P = .003 and area: LBP group 4.68 (2.6-7.28) cm2, control group 2.4 (2.1-3.34) cm2. The discriminating variables in the EO condition were the TDS for the LBP group and the anteroposterior mean velocity for the control group, while in the EC condition they were mediolateral dispersion and area for the LBP group. CONCLUSION: Individuals with chronic LBP had worse postural control performance than matched controls, and it is possible to characterize those with and without LBP with CoP variables.

RESUMO

BACKGROUND: Osteoarthritis (OA) is a chronic degenerative disease that commonly affects the knee joints. Individuals older than 65 years of age with knee OA have a greater risk of falls. However, there has been limited examination of the parameters of postural sway (increased time, speed, and postural sway area [center of pressure{CoP}]), and OA of the knee. OBJECTIVES: The primary objective of this study was to determine whether the CoP variables discriminate between patients with knee OA and matched healthy volunteers, and to correlate the CoP variables with the Activities-Specific Balance Confidence Scale (ABC) and Falls Self-Efficacy Scale (FES). The secondary objective was to compare the CoP of older women with OA with a control group in bipedal support condition with eyes opened and closed. DESIGN: Cross-sectional study. SETTING: University Biomechanics Laboratory. PARTICIPANTS: A total of 22 participants were divided into the following 2 groups of 11 participants each: an OA group (mean = 68 years, standard deviation = 7.4 years) and a control group (mean = 66 years, standard deviation = 4.4 years). METHODS: Static postural balance was measured by a portable force platform. Data were collected in both visual conditions (eyes open and closed), in random order. Three attempts of 30 seconds were allowed for each participant on the force platform, with a 1-minute interval between attempts. MAIN OUTCOME MEASURE: Variables were the CoP total displacement of sway (TDS, in centimeters), anteroposterior amplitude displacement (APAD, in centimeters), medial-lateral amplitude displacement (MLAD, in centimeters), total mean velocity (TMV, in centimeters per second), and dispersion of the center of pressure (AREA, in centimeters squared). RESULTS: The postural sway analysis found statistically significant differences in the eyes open condition for the TDS (P = .020), APAD (P = .042), TMV (P = .010), and AREA (P = .045). In the discriminant analysis, none of the CoP variables were able to classify the groups (P = .15). The correlation analysis showed that only the AREA with eyes closed was associated with the ABC Scale (rho = -0.42). CONCLUSIONS: Women with knee OA had greater postural sway when compared with a control group for the eyes open condition. CoP variables could not discriminate between the groups. The AREA was negatively correlated with the ABC Scale, when the eyes were closed. LEVEL OF EVIDENCE: III.

RESUMO

Objetivo: Criar e testar as propriedades psicométricas de um instrumento específico para quantificação da qualidade de vida de indivíduos com lesão da medula espinal. Método: A partir dos métodos de consenso existentes, foi escolhida a técnica Delphi para criação do questionário e o SF-36 como método critério. Resultados: A consistência interna foi α=0,827. A confiabilidade intra e interavaliadores se mostram alta pelo coeficiente de correlação intraclasse e teste de bland e altman pela diferença da média. Pode-se observar correlações fortes entre o QVLM e SF-36 nos domínios capacidade funcional e aspectos físicos e correlação moderada nos domínios estado de saúde e aspectos emocionais. Houve diferença significante entre as quatro aplicações do QVLM demonstrando que o questionário é sensível à mudança. Conclusão: O QVLM foi criado com metodologia adequada e a avaliação das propriedades psicométricas traduzem em um instrumento válido, confiável, consistente e sensível a mudanças

RESUMO

The aim of this study was to verify the reliability of the kinetic parameters of gait using an underwater force platform. A total of 49 healthy participants with a median age of 21years were included. The kinetic gait data were collected using a 0.6×0.6×0.1m aquatic force plate (Bertec®), set in a pool (15×13×1.30m) with a water depth of 1.20m and water temperature of 32.5°C. Participants walked 10m before reaching the platform, which was fixed to the ground. Participants were instructed to step onto the platform with their preferred limb and data from three valid attempts were used to calculate the average values. A 48-h interval between tests was used for the test-retest reliability. Data were analyzed using interclass correlation coefficients (ICC) and results demonstrated that reliability ranged from poor to excellent, with ICC scores of between 0.24 and 0.87 and mean differences between (d¯)=-0.01 and 0.002. The highest reliability values were found for the vertical (Fz) and the lowest for the mediolateral components (Fy). In conclusion, the force platform is reliable for assessing the vertical and anteroposterior components of power production rates in water, however, caution should be applied when using this instrument to evaluate the mediolateral component in this environment.
