RESUMO

OBJECTIVE: Accurate assessment of burn depth and burn wound healing potential is essential to determine early treatments. Infrared thermography (IRT) is a non-invasive and objective tool to do this. This systematic review evaluated the accuracy of IRT to determine burn wound healing potential. METHOD: This systematic review and meta-analysis used MEDLINE, EMBASE, CINAHL, PEDro, DiTA and CENTRAL databases. IRT data were extracted from primary studies and categorised into four cells (i.e., true positives, false positives, true negatives and false negatives). Subgroup analysis was performed according to methods used to capture thermal images. RESULTS: The search strategy identified 2727 publications; however, 15 articles were selected for review and 11 for meta-analysis. In our meta-analysis, the accuracy of IRT was 84.8% (63% sensitivity and 81.9% specificity). CONCLUSION: IRT is a moderately accurate tool to identify burn depth and healing potential. Thus, IRT should be used carefully for evaluating burn wounds.

RESUMO

OBJECTIVES: To compare acute effects of isometric abdominal exercises performed with or without vibration on the electromyographic activity and cutaneous temperature in the abdominal region of physically active individuals. METHODS: A randomized controlled crossover clinical trial was undertaken in thirty volunteers who completed one unique session of two different protocols of interventions apart from a week from each other, in a two-week study protocol. The subjects were randomly divided in to two groups of 15 volunteers; both were assigned to perform board exercise (30 s on the front, right and left lateral boards, with a rest interval of 2 min). The first group performed it on a vibrating platform at a frequency of 30 Hz for the first week, while the remaining participants executed the same exercise without stimulates vibration. In the second week the protocol was inverted. The outcome were surface electromyography (EMG) data for the rectus abdominis muscle (RAM) and cutaneous temperature (CT) of the abdominal region. Normality was accepted, and Student's t-tests were used to compare the measurements for dependents variables (P < 0.05). RESULTS: There were no differences in RAM activation and CT between protocols with or without vibration (P > 0.05). CT increased (P = 0.001) after both the exercises with and without vibration. CONCLUSION: The results suggest that there were no effects in cutaneous temperature or muscle activation through the use of vibration associated with isometric abdominal exercises.

RESUMO

BACKGROUND: Stroke is associated with high rates of falling and severe impairment of lower limb in patients who survive. OBJECTIVE: The aim of this study was to analyze the effectiveness of different montages of transcranial direct current stimulation (tDCS) on reducing falls and on lower limb function after acute stroke. METHODS: Sixty participants with acute stroke were randomly allocated into four groups with different electrode's setups: anodal, cathodal, bilateral and sham tDCS. Each patient received 10 stimulation sessions (five consecutive days for two weeks). Four Square Step Test, Occurrence of Falling Index, Overall Stability Index, Falls Efficacy Scale - International, Berg Balance Scale, Six-minute walk test and Sit to Stand Test were measured at baseline, post-treatment, and at one- and three-month follow-up. RESULTS: At baseline, no differences between the groups in terms of clinical and demographic characteristics were found. However, after treatment and during follow up, all the groups that received active stimulation showed greater reduction in the risk of falls and improved performance of the lower limb's motor skills when compared to the sham group. No significant differences were found between the three types of active montages in relation to the risk of falling. In relation to lower limb function, bilateral stimulation provided a higher improvement when compared to anodal and cathodal tDCS. CONCLUSIONS: This is the first trial with different setups of tDCS on acute stroke patients. tDCS presents as an effective treatment strategy in reducing the risk of falls and improving lower limb function after a stroke.

RESUMO

Introdução: Na natação, de modo geral, as estruturas que compõem o ombro são afetadas pelo gestual esportivo, porém, não se pode afirmar que isso promove o impingement. Objetivo: Avaliar o efeito da natação sobre o espaço subacromial, a amplitude de movimento e a força de rotação medial e lateral dos ombros de nadadores. Métodos: Foram analisados 52 sujeitos de ambos os gêneros, entre 12 e 17 anos e divididos em 2 grupos pareados: 1) grupo experimental: 26 nadadores (14 homens e 12 mulheres) e grupo controle: 26 sujeitos ativos não nadadores (13 homens e 13 mulheres). Resultados: Os dados foram analisados no SPSS (20.0) pelos testes t Student (independente) e Mann-Whitney, considerando-se α ≤ 0,05. A força de rotação medial foi 57 e 54% maior que a força de rotação lateral no grupo experimental (P<0,01), e 32 e 25% no grupo controle (P<0,01) para o membro dominante e membro não dominante, respectivamente. A razão força de rotação medial/força de rotação lateral e a amplitude de movimento foram maiores no grupo experimental (P<0,02 e P<0,01, respectivamente) quando comparada ao grupo controle. Conclusão: Os nadadores apresentaram maior amplitude de movimento, força de rotação medial e razão força de rotação medial/força de rotação lateral comparados ao grupo controle, sem alterar o espaço subacromial, comparado a valores normativos.(AU)

RESUMO

The purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players. Seventeen female volleyball players (18.94±2.49 years; 65.45±9.49 kg; 1.71±0.05 m; BMI=22.0±2.67 kg/m²) took part in this study. The dynamic balance was assessed through the Star Excursion Balance Test (SEBT). Comparisons between stabilization (no stabilizer/NS, orthosis/ORT and functional bandaging/FB) modes and the SEBT grid lines and inter-limb were carried out. The SEBT assessment showed a significant difference between the groups NS x ORT and NS x FB (p < .01), and between the lines (p< .01). Significant line/limb interaction in DL and NDL (p< .01) was detected. The external supports tested herein showed similar effects on balance, restricting lower limb's reach in the SEBT execution in some of tested directions.

RESUMO

This study aimed to evaluate the quadriceps femoris neural adaptations during isometric contractions using force and electromyogram (EMG) signals as visual biofeedback. Forty-two participants were randomly assigned to three groups: EMG group, tested with EMG biofeedback; Force group, tested with force biofeedback; and Control group, tested without biofeedback. Evaluations were performed pre (baseline) and post-tests to determine the maximum force and EMG amplitude during maximal voluntary isometric contraction (MVIC). The tests consisted of series of MVICs in which the participants were encouraged to surpass the force or EMG thresholds determined at baseline. The vastus lateralis EMG amplitude and knee extensor force increased significantly in all groups when compared the baseline and post-test evaluations values ​​(p < .05). EMG percentage gain was significantly different between Force and Control groups (p < .01), while force percentage gain was not different between groups. Force biofeedback was more effective in producing neural adaptations.

Este estudo avaliou as adaptações neurais do quadríceps durante contrações isométricas usando os sinais de força e eletromiografia (EMG) como biofeedback. Quarenta e dois sujeitos foram distribuídos em três grupos: EMG, testado com biofeedback da EMG; Força, testado com biofeedback de força; e Controle, testado sem biofeedback. As avaliações foram realizadas pré/pós-testes para determinar a máxima força e amplitude EMG durante contrações isométricas voluntárias máximas (CIVM). Os testes consistiram em séries de CIVM onde os sujeitos foram encorajados a ultrapassar os limiares de força e EMG inicialmente determinados. A amplitude EMG do vasto lateral e a força extensora do joelho aumentaram significativamente em todos os grupos quando comparadas as avaliações pré e pós-testes (p < 0,05). A porcentagem de ganho EMG foi significativamente diferente entre os grupos Força e Controle (p < 0,01), enquanto que a porcentagem de ganho da força não foi diferente entre os grupos. O biofeedback de força foi mais efetivo em produzir adaptações neurais.

Este estudio evaluó las adaptaciones neurales de cuádriceps durante contracciones isométricas usando los signos de fuerza y ​​electromiografía (EMG) como biofeedback. Cuarenta y dos sujetos fueron divididos en tres grupos: EMG, probado con biofeedback EMG; Fuerza, probado con biofeedback de fuerza; y control, probado sin biofeedback. Las avaluaciones se realizaron pre/post pruebas para determinar la máxima fuerza y amplitud EMG durante contracciones isométricas voluntarias máximas (CIVM). Las pruebas consistieron en series de CIVM en que los sujetos fueron encorajados a cruzar el umbral de fuerza y EMG ​​ inicialmente determinados. La amplitud EMG del vasto lateral y fuerza de los extensores de la rodilla aumentó significativamente en todos los grupos al comparar las avaluaciones pre y post pruebas (p < 0,05). El porcentaje de ganancia EMG fue significativamente diferente entre los grupos Fuerza y ​​control (p < 0,01), mientras que el porcentaje de aumento de la fuerza no fue diferente entre los grupos. Biofeedback de fuerza fue más eficaz en producir adaptaciones neurales.

RESUMO

Objetivo: Analisar as alterações termográficas em pacientes com lombalgia crônica sob diferentes intervenções fisioterapêuticas. Método: Selecionaram-se 33 indivíduos com lombalgia crônica que foram aleatorizados em quatro grupos: terapia manual (gTM; n=10); estabilização segmentar lombar (gESL; n=7); terapia combinada ­ TM + ESL (gTC; n=7); e orientações posturais/controle (gOP; n=9). Todos realizaram dez sessões fisioterapêuticas e avaliados, pré- e pós-tratamento, quanto à temperatura cutânea (termografia infravermelha) e dor (Escala Visual Analógica ­ EVA) na região lombar. Utilizou-se Anova (4x3x2) para comparar quatro grupos, três áreas (ALE, AC e ALD) e duas avaliações (pré- e pós- tratamento), para temperatura cutânea; e Anova (4x2) entre os quatro grupos, pré- e pós-tratamento, para a EVA, considerando α≤5%. Resultados: Não houve diferença significativa na temperatura da região lombar, comparando-se pré- e pós-tratamento; contudo, a EVA mostrou redução significativa para os grupos (P≤0,01). Conclusão: Apesar dos tratamentos não terem minimizado a temperatura na região lombar, diminuíram, drasticamente, o nível de dor nos grupos.

Objective: To analyze the thermographic changes in patients with chronic low back pain under different physical therapy interventions. Method: Thirty three chronic low back pain individuals were randomized into four groups: manual therapy (MTg; n=10), lumbar stabilization (LSg; n=7); combined therapy ­ MT + LS (CTg; n=7) and postural orientation/control (PGg; n=9). All individuals underwent ten physiotherapy sessions and evaluated pre- and post-treatment as skin temperature (infrared thermography), and pain in the lower back (Visual Analogue Scale ­ VAS). Anova (4x3x2) comparing four groups, three areas (LLA, CA and RLA) and two evaluations (pre- and post-treatment) for skin temperature; and Anova (4x2) between the four groups, pre- and post-treatment, were used for VAS, considering α ≤5%. Results: There was no significant difference in lower back temperature, comparing pre- and post-treatment; however, the VAS showed a significant reduction for all groups (P≤0.01). Conclusion: Although the treatments have not minimized the temperature in the lumbar region, they were able to decrease dramatically the level of pain, in all groups.

RESUMO

The objective this study was to evaluate intra and inter-rater and inter-instruments reliability of ankle inversion and eversion active range of motion. The study included 100 healthy individuals (71 women and 29 men; ages: 21.32±2.83 years old; body mass: 60.40±4.95 kg; height: 1.66±0.04 m; and body mass index: 21.89±2.83 kg/m2), who were submitted to measurement of ankle inversion and eversion using the universal goniometer and podalic arthrometer. We used the intra-class correlation coefficient (ICC) and Pearson's test, considering a 5% significance level. The results of this study demonstrated one very strong intra-rater ICC (0.91≥0.99; p<0.01) and a strong inter-rater (0.61≥0.9; p<0.01) in both the first and second measurements, especially when measured with the podalic arthrometer (ICC>0.8; universal goniometer: ICC<0.8). The inter-instruments correlation was proved as being regular and significant (0.31≥r≤0.6; p<0.01) for all evaluators and evaluations. Both tested instruments can be used in physical therapy practice for measurements of ankle inversion and eversion due to the high reliability presented, regardless of the evaluator's previous experience, especially the podalic arthrometer when compared to the universal goniometer, which is probably due to the lower influence that the appraiser has on the instrument during measurements.

El objetivo del estudio fue evaluar la fiabilidad de las medidas intra e inter-evaluadores e inter-instrumentos de la amplitud del movimiento activa de eversión e inversión del tobillo. Participaron de este estudio 100 sujetos sanos (71 mujeres y 29 hombres; edad: 21,32±2,83 años; masa corporal: 60,40±4,95 kg; estatura: 1,66±0,04 m e índice de masa corporal: 21,89±2,83 kg/m2), que fueron sometidos a la medición de inversión y eversión del tobillo con goniómetro universal y artrómetro podálico. Se utilizó el coeficiente de correlación intraclase (CCI) y la prueba de Pearson, teniendo en cuenta un nivel de significancia del 5%. Los resultados del estudio demostraron un CCI intra-evaluador muy fuerte (0,91≥0,99; p<0,01) y del inter-evaluador fuerte (0,61≥0,9; p<0,01), en la primera y en la segunda medición, especialmente cuando medidas con el artrómetro podálico (CCI>0,8; goniómetro universal: CCI<0,8). La correlación inter-instrumentos se mostró regular y significante (0,31≥r≤0,6; p≤0,01) para todos los evaluadores y evaluaciones. Los dos instrumentos probados pueden ser utilizados en las medidas de inversión y eversión del tobillo por su alta fiabilidad presentada, independientemente de la experiencia del evaluador. Sin embargo, las medidas del artrómetro podálico mostraron una mayor fiabilidad en comparación al goniómetro universal probablemente por la menor influencia que el evaluador ejerce sobre el instrumento durante la medición.

A correlação interinstrumentos mostrou-se regular e significante (0,31≥r≤0,6; p<0,01) para todos os avaliadores e avaliações. Ambos os instrumentos testados podem ser utilizados na prática fisioterapêutica para as medidas de inversão e eversão do tornozelo pela alta confiabilidade apresentada, independentemente da experiência do avaliador, especialmente o artrômetro podálico comparado ao goniômetro universal, provavelmente, pela menor influência que o avaliador exerce sobre o instrumento durante a medida.
