Efeito do kinesio taping® no desempenho neuromuscular do quadríceps e no equilíbrio em sujeitos submetidos à reconstrução do ligamento cruzado anterior: ensaio clínico e randomizado

Objetivo: Investigar os efeitos imediatos do Kinesio Taping® no desempenho neuromuscular do Quadríceps Femoral (QF) de indivíduos submetidos à reconstrução do Ligamento Cruzado Anterior (LCA). Metodologia: trata-se de um ensaio clínico e randomizado composto por 45 indivíduos do sexo masculino que se encontravam entre 12ª e 17ª semanas após reconstrução do LCA. Todos foram submetidos a uma avaliação inicial composta pela análise do equilíbrio postural, através da baropodometria; determinação do Senso de Posição Articular (SPA), seguidas das avaliações isocinéticas excêntricas e concêntricas a 600/s, concomitante com a captação do sinal eletromiográfico do músculo Vasto Lateral (VL). Posteriormente foram alocados de forma aleatória em Grupo Controle (GC), Grupo Placebo (GP) e Grupo Experimental (GE). Os indivíduos do GE foram submetidos ao protocolo sugerido (aplicação do Kinesio Taping® no QF do membro acometido), enquanto os do GP utilizaram a aplicação do Kinesio Taping® sem as recomendações propostas pelo método. Já os indivíduos do GC permaneceram em repouso por dez minutos, sendo todos os indivíduos submetidos a uma reavaliação de forma idêntica à primeira. Foram analisadas as seguintes variáveis: pico de torque médio, pico de torque/peso corporal, potência muscular e erro absoluto do SPA para a dinamometria; amplitude ântero-posterior e médio-lateral para a baropodometria; e a amplitude de ativação muscular (Root Means Square - RMS) por meio da eletromiografia de superfície. Resultados: Nenhuma das variáveis analisadas apresentou diferenças intergrupo ou intragrupo. Conclusão: O Kinesio Taping® não altera o desempenho neuromuscular do quadríceps femoral de indivíduos submetidos à reconstrução do LCA para nenhuma das variáveis analisadas.

Análise da distribuição do volume pulmonar total e compartimental de crianças com peso normal e obesidade em diferentes posturas

Introdução: A obesidade infantil apresenta incidência crescente e as possíveis comorbidades, como alteração da função respiratória, estão cada vez mais presente nessa faixa etária. O tecido adiposo impõe carga ao sistema respiratório o que leva a um padrão restritivo. Essa condição sofre alterações com as mudanças posturais, onde a gravidade influencia o padrão respiratório de acordo com o posicionamento adotado. Objetivo: Avaliar a distribuição dos volumes total e regional e o movimento tóracoabdominal de crianças e adolescentes que estão acima do peso nas posturas supino e sentado. Métodos: Cinqüenta e duas crianças/adolescentes (8-12 anos) divididas em três grupos: Grupo Obeso (GO=22); Grupo Sobrepeso (GSP=9); Grupo Controle (GC=21) foram avaliadas quanto às medidas antropométricas, teste de função pulmonar, exame das pressões respiratórias máxima e a pletismografia optoeletrônica em duas posturas, supino e sentado, durante a respiração tranquila. Resultados: As crianças que estão obesas apresentaram maiores valores em relação ao GSP e GC das seguintes variáveis espirométricas: volume expiratório forçado no primeiro segundo (VEF1) (p<0.05) e capacidade vital forçada (CVF) (p<0.01). No exame de manovacuometria o GO apresentou um aumento na pressão inspiratória máxima (PImáx) (p<0.01) em comparação com os outros grupos. Quanto à distribuição do volume corrente, o GO possui uma maior contribuição do compartimento abdominal (AB) na postura supina (p<0.05) em relação ao GC e GSP, enquanto que na postura sentada os grupos não diferiram em relação à distribuição dos volumes. O GO apresentou maior assincronia na postura supina (p<0.05) e maior velocidade de encurtamento (p<0.05) em relação os outros grupos. Conclusão: A obesidade em crianças/adolescentes não provoca prejuízos na função pulmonar, incrementa a força muscular inspiratória, aumenta a participação do compartimento AB e a assincronia no MTA na postura em supino, conclui-se que a postura supina associada à obesidade provoca aumento da sobrecarga do diafragma, desfavorecendo o desempenho do sistema respiratório.

Avaliação da pressão inspiratória nasal sniff na população obesa

Introdução: a avaliação da pressão inspiratória nasal (SNIP) é considerada uma manobra complementar da Pressão Inspiratória Máxima estática (PImax) em várias condições clínicas, porém não há relatos na obesidade. Por outro lado, a obesidade tem um importante impacto nos músculos respiratórios especialmente com maiores gordura abdominal o que provavelmente pode ser detectado na avaliação da SNIP que mensura mais precisamente a pressão diafragmática. Objetivo: analisar em obesos a relação entre SNIP e variáveis respiratórias e marcadores de adiposidade. Material e Método: num estudo transversal um total de 92 obesos (38.3±10.2 anos) sem história de doença respiratória ou cardíaca diagnosticada. Foram avaliados na espirometria (capacidade vital forçada-CVF; volume expiratório forçado no primeiro segundo-VEF1; volume de reserva expiratório-VRE) e pressões respiratórias estática (PImax, PEmax e SNIP) e dinâmica (ventilação voluntária máxima-VVM). Sendo considerados os marcadores de adiposidade: índice de adiposidade corporal-IAC; índice de massa corporal-IMC e circunferências do quadril (CQ), cintura (CC) e pescoço (CP). Resultados: 65 obesos mórbidos (IMC=50.8±8.1Kg/m2) e 27 obesos não mórbidos (IMC=35.6±2.7Kg/m2) foram homogêneos (p>0.05) na SNIP (99.1±24.5cmH2O, 87% do predito) e PImax (107.3±26.4cmH2O, 109% do predito). Existe correlação (r=0.5) entre SNIP e PImax somente no grupo de obesos mórbidos. De acordo com as correlações houve associação entre variáveis respiratórias (CVF r=0.48; VEF1 r=0.54; e VVM r=0.54), valores antropométricos (idade r=-0.44) e SNIP somente para os obesos mórbidos. Esses achados foram certificados quando também comparados a quantidade de gordura ao redor do pescoço (CP≥43cm). O modelo de regressão linear stepwise mostrou que a VVM parece ser o melhor preditor para explicar a SNIP nos obesos mórbidos. Nestes obesos a SNIP foi levemente mais baixa (87%predito) que os valores esperados para indivíduos brasileiros saudáveis. Conclusão: em obesos mórbidos a SNIP é moderadamente relacionada a PImax. A SNIP parece ser mais relacionada a VVM que à marcadores de adiposidade.

Relação entre desempenho funcional e indicadores de doença arterial obstrutiva periférica em idosas

The presence of peripheral arterial disease (PAD) increases the risk and vulnerability to adverse clinical outcomes in the elderly. Like this, we investigated the relationship between functional performance and indicators of PAD in elderly women. METHODS: Cross-sectional study in which 54 elderly were assessed by questionnaire mini mental state examination, Short Phisical Performance Battery (SPPB), ankle-brachial index (ABI), human activity profile (HAP) and Edinburgh questionnaire. Statistical analysis was performed using ANOVA, t test and Pearson correlation. We considered p <0.05 as significance level. RESULTS: The mean age SPPB and ABI were 69.2 (± 6.9) years, SPPB 9.42 (± 2.55) and ABI 1.04 (± 0.14). The prevalence of PAD was 16.3%. There was a significant correlation between ABI and gait speed (r = 0.75, p = 0.001) and between PAH with SPPB (p = 0.001). CONCLUSIONS: It is suggested that the decline in functional performance in older, expressed in gait velocity component of the SPPB, is related to the presence of PAD

Relação entre função sexual, sintomatologia depressiva e qualidade de vida em mulheres grávidas

INTRODUCTION: Human sexuality is recognized as one of the pillars of quality of life. In women, sexual function is influenced throughout life by many factors that can lead to the appearance of changes in the cycle of sexual response, and hence the quality of life (QOL). Pregnancy is a period of change, leaving them physically and mentally vulnerable, which may affect sexual function and quality of life during pregnancy. OBJECTIVE: To investigate the relationship between sexual function, presence of depressive symptoms and quality of life in pregnant women. METHODS: The study included 207 pregnant women attending prenatal examination of the Maternity Divine Love, Parnamirim / RN and the participants of the Course for Pregnant Women of the Department of Physical Therapy at UFRN (central campus). Initially it was applied, a questionnaire containing questions about sociodemographic, gynecological and obstetric data, as well as body and sexual self-knowledge. Sexual function was assessed using the Sexual Function Index Female (Female Sexual Function Index - FSFI). To assess the quality of life, we used the Quality Index Ferrans Life & Powers mom. The presence of depressive symptoms was verified by applying the Beck Depression Inventory. The Shapiro-Wilk test for normality was carried variables, Mann-Whitney test for carrying out the comparisons and the Wilcoxon test for comparing the monthly sexual frequency before and during pregnancy. Multiple linear regression was used to verify the relationship between sexual function, depressive symptoms and quality of life. We used the Spearman correlation to check correlation between the variables. Ap value <0.05 was adopted. RESULTS: Sexual function and depressive symptoms were related quality of life (R2 = 0.30, p <0.001). Depression had a moderate negative correlation with quality of life (0.53; p <0.001), whereas sexual function showed a positive correlation with low quality of life (0.22; p = 0.001). The planning of pregnancy, education and income shown to influence depression scores. With respect to sexual function, it was seen that during pregnancy, a reduction in the monthly frequency of sexual partner (Z = -10.56; p <0.001). Among the sexual domain, just the pain, showed a statistically significant difference compared between the second and third quarter (Z = -1.91, p <0.05). The score of the quality of life of women with sexual dysfunction was xvii significantly lower than that pregnant women without dysfunction (Z = -2.87, p = 0.004). Conclusion: Sexual function and the presence of depressive symptoms are related to the quality of life of pregnant women.

Alterações de equilíbrio postural e qualidade de vida em mulheres no ciclo gravídico puerperal

INTRODUCTION: The pregnancy and childbirth cause many changes in a woman's life, whether physical, hormonal, emotional or social. Such changes may affect the postural balance and the quality of life of women in pregnancy and may persist after delivery. To analyze changes in postural balance and quality of life in women in pregnancy and postpartum. METHODS: This study consisted of 47 women participants of the Course for Pregnant Women of the Department of Physical Therapy at UFRN, evaluated during pregnancy (2° or 3° trimester) and in the period 1-8 months postpartum. In all participants was evaluated the postural balance, the Balance Master® in five specific tests: (1) Modified Clinical Test of Sensory Interaction on Balance-MCTSIB; (2) Rhythmic Weight Shift Test - RWS (3) unilateral stance - US, (4) Sit to Stand - STS, and (5) Walk Across - WA. The quality of life (QoL) was assessed by applying the Quality Score of life Ferrans & Powers (IQVFP), both during pregnancy and in the postpartum period. For statistical analysis we used the Statistical Package for Social Sciences software for Personal Computer- SPSS (version 20.0), applying the tests: Shapiro-Wilk to assess the normality of the data; Chi-square to analyze the frequency of postural balance changes in the two groups of pregnancy and postpartum in both groups; McNemar test to analyze balance disorders frequency of related samples in the two time points; to compare the behavior of postural balance during pregnancy and postpartum, and to compare the QoL between the periods, we used the Wilcoxon test; and yet, the MannWhitney test to compare the QoL scores in the two groups of pregnancy and postpartum in both groups. We adopted p-value <0.05. RESULTS: Comparing the postural balance during pregnancy and postpartum in MSTSIB test has statistical difference in unstable surface with closed eyes (p=0.001) and in the US test, the speed of oscillation with right leg with eyes closed (p=0,03). Quality of life, there was statistical difference between the scores only among postpartum groups, the family domain (p=0.03); and to comparing pregnancy and postpartum in domain health and operation (p=0.02) and the Socioeconomic domain (p=0.01). CONCLUSIONS: It was observed that the balance changes present during pregnancy persist postpartum, and the quality of life is considered good by women, both during pregnancy and postpartum.

Influência de mudanças de fase no ciclo claro-escuro sobre o controle autonômico cardíaco de ratos

Introduction: The circadian system has neural projections for the Autonomic Nervous System (ANS), directly interfering with sympathetic-vagal modulation of the cardiovascular system. Disturbances in the circadian system, such as phase changes in light-dark cycle (LD), has been related to the risk of development of cardiovascular diseases due to increased sympathetic tone and reduction o Heart Rate Variability (HRV - RR intervals). Purpose: Investigate the interaction between Circadian Timing System and cardiac autonomic control in rats. Materials and methods: We used 18 Wistar rats (♀, age = 139.9 ± 32.1 days, weight = 219.5 ± 16.2 g), divided into three distinct groups: Control (CG), phase delay of 6h (GDe) and phase advance of 6h (GAd). Three animals were excluded during data collection (CG/GDe/GAd - n=5). Telemeters were surgically implanted in each animal for continuous acquisition of electrocardiographic (ECG) signals (duration of 21 days in the CG and 28 days in GDe/ GAd). A LD cycle was established 12h: 12h, beginning of light at18:00h and dark at 06:00h. The animals remained in the same CG LD cycle throughout the experimental period, while, on the 14th day of registration, the GDe and GAd underwent a delay and an advance in 6h, respectively. Throughout the experimental period, the locomotor activity (LA), the mean heart rate (mHR) and variables related to iRR [mean RR (mRR), SDNN, RMSSD, LF, HF and LF/ HF ratio ] were recorded. All data were analyzed in blocks of 3 and 7 days, for the presence of circadian rhythm, values of Cosinor - mesor, amplitude and acrophase (paired t test), phase relationship, differences between light and dark (t test independent), averages every 30 minutes along each time series (two-way ANOVA with post hoc Bonferroni). The data block B1,M1 and M2 in CG served as benchmarks for comparisons between series of analysis of the GAT/GAV. Results: We observed circadian rhythmicity in the variables LA, mRR and mFC(p<0.01). mRR and mFC showed phase relationship with the LA in all three groups, being less stable in GAd. In the CG, no significant differences between blocks were found in any of the analyzes(p>0.05). Among the 7 day blocks, there was a significant reduction in mRR(p=0.04) and mFC(p=0.03) in GDe and significant reduction in HF mean(p=0.02) in GAd; and between 3 day blocks, a significant increase of LF/HF(p= 0.04) in the GDe; besides mRR(p=0.03), SDNN(p=0.04), RMSSD (p=0.04), LF (p=0.01) and HF(p=0.02) significant increase in the GAd. It was found that the differences between the means of the mRR, LA and mFC in light and dark phases were not significant after phase changes in some of the blocks/moments (GDe and GAd). No significant results were found when comparing rhythmic variables means every 30 minutes over the blocks, except for a significant decrease in mRR at the middle of the dark phase (B2) and the start of light phase (B3) - (p<0.01). Conclusion: phase advances and delays (6h) altered cardiac autonomic control in the experimental groups by temporarily HRV decrease. Phase advances apparently had greater negative interference in this process, in relation to the phase delays.

Prevalência e fatores associados à diminuição da função pulmonar em obesos em pré-operatório de cirurgia bariátrica

Introduction: Obesity shows changes in pulmonary function and respiratory mechanics, however, little is known regarding the prevalence of worsening respiratory function when considering the increase in central or peripheral adiposity or general obesity. Objectives: To analyze the association between anthropometric adiposity and decreased lung function in obese. Materials and Methods: Patients eligible for this study obese individuals (IMC≥30kg/m2) in pre-bariatric surgery and referred for Treatment Clinic of Obesity and Related Diseases, located at the University Hospital Onofre Lopes (HUOL), from October 2005 and July 2014. The evaluation included clinical information and measurement of anthropometric measures (body mass index (BMI), body fat index (BFI) and waist circumference (WC) and neck (NC)) and spirometric. The prevalence and analysis by Poisson regression was performed considering the following outcome variables: forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and Maximum Voluntary Ventilation (MVV) and as predictor variables were considered: BMI, IAC, WC and NC and as control variables: age, gender, smoking history and comorbidities (diabetes mellitus, dyslipidemia and hypertension). Statistical analysis was performed using Statistical Package for Social Sciences software (SPSS - version 20.0). Results: We analyzed 384 individuals, 75% women, mean BMI: 46.6 (± 8.7) kg/m2, IAC: 49.26 (± 9.48)%, WC: 130.84 (± 16.23) cm and NC: 42.3 (± 4.6) cm. The higher prevalence of FVC and FEV1 <80% was observed in individuals with NC above 42 cm, followed those with a BMI above 45 kg/m2. Multivariate analysis using Poisson regression showed as risk factors associated with FVC <80%, the variables: NC above 42 cm (odds ratio (OR) 2.41) and BMI over 45Kg/m2 (OR 1.71 ). As for FEV1 <80% predicted, all predictor variables were associated, with the largest odds presented by the NC (3.40). MVVV was not associated with any studied varaible. Conclusion: Individuals with NC above 42 cm had higher prevalence of reduced lung function and the NC was the measure with the highest association with reduced lung function in obese.

Normalização de eletromiografia de superfície dos músculos respiratórios em sujeitos saudáveis: contração voluntária máxima máxima isométrica versus pressões respiratórias máximas

Aim : To evaluate and to standardize surface electromyography (sEMG) normalization procedures for respiratory muscles by comparing muscle activation during Maximal Voluntary Isometric Contraction (MVIC) and Maximal Respiratory Pressures (MIP, MEP and sniff test). Methods: Healthy subjects were evalua ted regarding demographics, spirometry and sEMG during the five maneuvers: sniff test, MIP , MEP and Maximal Voluntary Isometric C ontraction (MVIC) of RA, SCM and SC A . For electrode placement, skin was prepared with abrasion, followed by shaving in the foll owing regions for acquisition of el ectromyographic signals: (1) SC M: lower third of the distance between the mastoid process and t he sternoclavicular joint; (2) SC A : 5 cm to the right from the sternoclavicular joint and at this point, up to 2 cm; and (3 ) RA: the level of umbilicus, 4 cm to the right. In electromyographic variables analysis , the data normality was assessed by Shapiro - Wilk test. Comparisons among studied maneuvers were performed by Friedman Test and Dunn’s post - hoc for multiple comparisons a mong inspiratory maneuvers, and Mann Whitney test for expiratory maneuvers. Subgroups differences between genders were performed by Student's t test or Mann - Whitney test according to data normality. Results: 35 subjects participated in the study, b ut 5 we re excluded (BMI> 25 kg/ m²). Sample consisted of 30 subjects (1 5 women), mean age 27.3±7.43 years, BMI 22.2 ± 1.69 kg/m² and spirometric indices within normal limits. Specific MVIC for SCM, SCA and RA showed the highest RMS. When we grouped sample into gender we found no difference among RMS values for the studied SCM maneuvers, while for SCA, MVIC SCM / SCA was the one with the highest RMS and for RA, MVIC RA in men. Once considering women, MVIC SCM/SCA showed the highest RMS for SCM, SCA and MVIC RA showed t he highest value for RA. Conclusion: MVIC for SCM, SCA and RA muscles showed the highest RMS values. When comparing RMS between the studied groups, there was no significant difference between men and women.

Efeito tardio do kinesio taping na função do membro inferior e no desempenho neuromuscular do quadríceps femoral de mulheres saudáveis: ensaio clínico e randomizado

Introduction: Kinesio Taping (KT) has been used in healthy people to improve neuromuscular performance, however, few studies have evaluated its chronic effects, despite being suggested. Objective: To analyze the chronic effects of KT on neuromuscular performance of the quadriceps, the oscillation of the center of pressure and lower limb function in healthy women. Methods: blinded, randomized, controlled trial, composed of 60 women (mean age 21.9 ± 3.3 years and BMI 22.3 ± 2.2 kg / m2) submitted to the evaluation of oscillation of the center of pressure through the baropodometry, the lower limb function by the hop test, isokinetic knee performance, the electromyographic activity of the vastus lateralis (VL) and joint position sense of the knee (JPS). Then, participants were randomly divided into three groups of twenty: control - did not apply the KT; placebo - application of KT without tension on the quadriceps; Kinesio Taping - application of KT with tension in the same muscle group. The evaluations were conducted in five moments: prior to application of KT, immediately after the application, 24h, 48h after application and 24 hours after its removal (72h). SPSS 20.0 was used for statistical analysis. The KS test was used to verify the data normality, the Levene test for homogeneity of variances and a mixed-model ANOVA 3x5 to check intra and inter-group differences. Results: there was no difference in peak torque, the power, nor the electromyographic activity or SPA (p> 0.05) between groups. The displacement speed of center of pressure reduced immediately after the application on kinesio taping group (p <0.001), but with no differences between the groups (p = 0.28). There was a reduction in the time of peak torque among the three groups in the evaluations after KT application (p <0.001) and an increase in single hop in all groups (p <0.001), but with no differences between them. Conclusion: KT can not change, in a chronic way, the lower limb function, the oscillation of the center of pressure, the isokinetic performance, the JPS of the knee and the electromyographic activity of VL muscle in healthy women.

Influência da paridade, do tipo de parto e do nível de atividade física sobre a musculatura do assoalho pélvico em mulheres na pós-menopausa

The post-menopause stage is characterized by hormonal and organic alterations of ovarian failure. One of the most important of these is muscles alterations of the pelvic floor (MPF). According to current literature, in young women gynecological and obstetric factors, as well as lifestyles and habits influence that loss of function. However, there is still uncertainty about the influence of those variables in the MPF functions in post-menopause women. Thus, this study aimed at seeing if there is an influence from number of births, the type of birth and the level of physical activity on the MPF of post-menopause women. Another objective of this study was to compare MPF force in women who had had vaginal births with those who had been subjected to cesarean sections, those with different levels of physical activity and those with artificial and natural menopause in the initial and latter stages. Furthermore, the test of muscular force was compared to perineometry. Using observational, analytical and transversal observations, 100 women in the post-menopausal stage of life, between the ages of 45 and 65, were examined. They were divided according to the menopausal stage into three groups: women who had undergone hysterectomies, those in the initial stages of postmenopause and those in the late stage of postmenpause. The patients were questioned about social, demographic, gynecological and obstetric factors. All the volunteers were submitted to a physical examination where their height and weight were measured to arrive at the corporal mass index and their waist measurements were taken. The evaluation of the pelvic floor was conducted with muscular force tests and perineometry. These results were analyzed with statistical description and ANOVA statistical tests, multiple regression and Kolmogorov-Smirnov evaluations. The results showed homogeneity with regard to social demographic and anthropometric characteristics among the women in the final test sample (n=85). It was also seen that most of the women in all three groups were married (p=0.51) and catholic (p=0.13). The average per capital income varied between $R585.47 (+/-466.67) and $R1,271.83 (+/-1,748.95), with no significant difference between the groups (p=0.05). The G>6 group presented an average age between 58.95 (+/-3.96) which was significantly greater that the G<6 group´s average age (53.21+/- 3.88) (p=0.000). There was no difference between the groups´ anthropometric characteristics of weight (p=0.32), height (p=0.72) and corporal mass index (p=0.34), nor in the waist measurements (p=0.33). Furthermore, no significant difference was noted in the MPF function of women who had had normal births, cesarean sections or a combination of the two (TFM p=0.897; perineum measurement p=0.502). Likewise, no differences were seen in the MPF function of women who had one, two to three or four or more births (TFM p=0.28, perineum measurement p=0.13). Finally, no difference was perceived among those with different levels of physical activity (TFM p=0.663; perineum measurement p=0.741). Therefore, we found that the type of delivery, number of births and physical activity had no influence on the muscular function of the pelvic floor among the women studied. It is believed that decline in muscular function in post-menopause women is fundamentally related to the process of aging.

Atividade eletroencefalográfica de pacientes com acidente vascular cerebral na aprendizagem motora de um jogo baseado em realidade virtual

Stroke is the leading cause of long-term disability among adults and motor relearning is essential in motor sequelae recovery. Therefore, various techniques have been proposed to achieve this end, among them Virtual Reality. The aim of the study was to evaluate electroencephalographic activity of stroke patients in motor learning of a virtual reality-based game. The study included 10 patients with chronic stroke, right-hande; 5 with left brain injury (LP), mean age 48.8 years (± 4.76) and 5 with injury to the right (RP), mean age 52 years (± 10.93). Participants were evaluated for electroencephalographic (EEG) activity and performance while performing 15 repetitions of darts game in XBOX Kinect and also through the NIHSS, MMSE, Fugl-Meyer and the modified Ashworth scale. Patients underwent a trainning with 45 repetitions of virtual darts game, 12 sessions in four weeks. After training, patients underwent reassessment of EEG activity and performance in virtual game of darts (retention). Data were analyzed using ANOVA for repeated measures. According to the results, there were differences between the groups (PD and PE) in frequencies Low Alpha (p = 0.0001), High Alpha (p = 0.0001) and Beta (p = 0.0001). There was an increase in alpha activation powers and a decrease in beta in the phase retention of RP group. In LP group was observed increased alpha activation potency, but without decrease in beta activation. Considering the asymmetry score, RP group increased brain activation in the left hemisphere with the practice in the frontal areas, however, LP group had increased activation of the right hemisphere in fronto-central areas, temporal and parietal. As for performance, it was observed a decrease in absolute error in the game for RP group between assessment and retention (p = 0.015), but this difference was not observed for LP group (p = 0.135). It follows then that the right brain injury patients benefited more from darts game training in the virtual environment with respect to the motor learning process, reducing neural effort in ipsilesionais areas and errors with the practice of the task. In contrast, patients with lesions in left hemisphere decrease neural effort in contralesionais areas important for motor learning and showed no performance improvements with practice of 12 sessions of virtual dart game. Thus, the RV can be used in rehabilitation of stroke patients upper limb, but the laterality of the injury should be considered in programming the motor learning protocol.

Efeitos do Kinesio Taping® sobre os marcadores clínicos indiretos de dano muscular induzido pelo exercício excêntrico: ensaio clínico randomizado

Objective: analyze the effect of Kinesio Taping (KT) on the indirect clinical markers of muscle damage induced by eccentric exercises in the elbow flexors in healthy individuals. Materials and methods: It is a randomized controlled trial involving sixty volunteers at age group between 18 and 28 years randomly selected. The sample into three groups with twenty participants: control group (CG) – eccentric protocol without KT, KT group – eccentric with tensioned KT, placebo group – eccentric protocol KT with no tension. The evaluations took place at four moments; the first one was the basis line (AV1), after the second protocol (AV2) and the following two groups 24 (AV3) and 48 hours (AV4) after the intervention protocol. The muscle damage was induced by sixteen maximum eccentric contractions of the elbow flexors from the non-dominant limb, divided in two sets of eight repetitions, at 60º/s, with two minutes interval. The variables analyzed were: the joint amplitude in rest, the level of pain, the joint position sense (JPS) followed of isokinetic checking with electromyographic sign capitation. These data were analyzed in software SPSS 20.0. The normality was identified by Kolmogorov-Smimov examination and then, being used the ANOVA mixed model with significance of 5%. Outcomes: a decrease was observed at joint amplitude moreover, an immediate increase of pain wich increased after 24 and remained until 48 hours at all groups searched. There was not difference at the JPS. The variables peak torque, average peak torque, total work and mean power mean reduced until 48 hours after muscle lesion in all groups. Among the groups, there was no difference in EMG values and for any of the variables. Conclusion: The KT did not influence at the indirect clinical markers of muscle lesion induced by eccentric exercises in the elbow flexors in healthy people.

The evaluations took place at four moments; the first one was the basis line (AV1), after the second protocol (AV2) and the following two groups 24 (AV3) and 48 hours (AV4) after the intervention protocol. The muscle damage was induced by sixteen maximum eccentric contractions of the elbow flexors from the non-dominant limb, divided in two sets of eight repetitions, at 60º/s, with two minutes interval. The variables analyzed were: the joint amplitude in rest, the level of pain, the joint position sense (JPS) followed of isokinetic checking with electromyographic sign capitation. These data were analyzed in software SPSS 20.0. The normality was identified by Kolmogorov-Smimov examination and then, being used the ANOVA mixed model with significance of 5%. Outcomes: a decrease was observed at joint amplitude moreover, an immediate increase of pain wich increased after 24 and remained until 48 hours at all groups searched. There was not difference at the JPS. The variables peak torque, average peak torque, total work and mean power mean reduced until 48 hours after muscle lesion in all groups. Among the groups, there was no difference in EMG values and for any of the variables. Conclusion: The KT did not influence at the indirect clinical markers of muscle lesion induced by eccentric exercises in the elbow flexors in healthy people.
