Kinesio Taping(®) does not alter neuromuscular performance of femoral quadriceps or lower limb function in healthy subjects: randomized, blind, controlled, clinical trial.

The aim of this study was to analyze the immediate effects of applying Kinesio Taping(®) (KT) on the neuromuscular performance of femoral quadriceps, postural balance and lower limb function in healthy subjects. This is a randomized, blind, controlled, clinical trial, where sixty female volunteers (age: 23.3 ± 2.5 years; BMI: 22.2 ± 2.1 kg/m(2)) were randomly assigned to three groups of 20 subjects each: control (10 min at rest); nonelastic adhesive tape (application over the rectus femoris, vastus lateralis and vastus medialis muscles); and KT (KT application over the same muscles). All individuals were assessed for single and triple hops, postural balance (by baropodometry), peak concentric and eccentric torque and electromyographic activity of vastus lateralis, before and after interventions. No significant differences in electromyographic activity of the VL or concentric and eccentric knee peak torque were recorded, between groups and initial and final assessment in any of the three groups. We also observed no significant alteration in single and triple-hop distance and one-footed static balance between the three groups. Application of KT to RF, VL and VM muscles did not significantly change lower limb function, postural balance, knee extensor peak torque or electromyographic activity of VL muscle in healthy women.

Immediate effects of Kinesio Taping® on neuromuscular performance of quadriceps and balance in individuals submitted to anterior cruciate ligament reconstruction: A randomized clinical trial

OBJECTIVES Investigate the immediate effects of Kinesio Taping(®) on neuromuscular performance of femoral quadriceps and balance in individuals submitted to anterior cruciate ligament reconstruction. DESIGN This is a randomized clinical trial. METHODS Forty-seven male participants, between 12 and 17 weeks after anterior cruciate ligament reconstruction, underwent initial assessment consisting of postural balance analysis using baropodometry, followed by eccentric and concentric isokinetic assessment at 60°/s of knee extensors, concomitant to electromyographic signals captured from the vastus lateralis muscle. They were then randomly allocated to one of the following groups: control, placebo and Kinesio Taping(®). Kinesio Taping(®) group participants were submitted to Kinesio Taping(®) on the femoral quadriceps of the affected limb, while placebo group subjects used the same procedure without the tension proposed by the method. The control group remained at rest for 10min. All participants were reassessed following the same procedure as the initial evaluation. The following variables were analyzed: peak torque/body weight and muscle potential using dynamometry; amplitude of antero-posterior and latero-lateral displacement from the center of pressure using baropodometry; and amplitude of muscle activation (root mean square) applying surface electromyography. RESULTS None of the variables analyzed showed significant intergroup or intragroup differences. CONCLUSIONS Kinesio Taping(®) does not alter the neuromuscular performance of femoral quadriceps or balance of subjects submitted to anterior cruciate ligament reconstruction, for any of the variables analyzed.

Delayed effect of Kinesio Taping on neuromuscular performance, balance, and lower limb function in healthy individuals: a randomized controlled trial

ABSTRACT Background Kinesio Taping (KT) is an elastic bandage that aims to improve neuromuscular performance, although there is no consensus as to its benefits. Objective To analyze the immediate and delayed effects of KT on the neuromuscular performance of the femoral quadriceps, on balance, and lower limb function in healthy subjects. Method This is a randomized controlled trial. Thirty-six women with a mean age of 22.2±3.6 years and BMI of 22.5±2.3 Kg/m2 were divided into three groups: control, with ten minutes of rest (control, n=12), application of Kinesio Taping without tension (placebo, n=12) and with tension (KT, n=12) on the quadriceps. The primary outcome was isokinetic performance, while secondary outcomes were the single-hop test, one-footed static balance, and electromyographic activity. The evaluations were carried out in five stages: 1) before application of KT, 2) immediately after the application of KT, 3) after 24h, 4) after 48h, and 5) after 72h. Mixed ANOVA was used to determine differences between groups. Results There was no change in one-footed static balance, electromyographic activity of the VL in the lower limb function, nor in isokinetic performance between groups. Conclusion KT promotes neither immediate nor delayed changes in neuromuscular performance of the femoral quadriceps in healthy women.

Efeitos do aquecimento e do alongamento na resposta neuromuscular dos isquiotibiais

INTRODUCAO: A preparacao para a atividade esportiva frequentemente envolve aquecimento e/ou alongamento, no intuito de prevenir lesoes e/ou melhorar o desempenho. No entanto, a maneira como essas praticas podem interferir nos mecanismos neuromusculares de controle articular nao e clara.OBJETIVO: Analisar o efeito imediato do alongamento e do aquecimento, isolados ou associados, no tempo de latencia muscular (TLM) e na amplitude de ativacao dos isquiotibiais, apos perturbacoes repentinas da articulacao do joelho.METODOS: Sessenta voluntarios do sexo feminino (media de idade de 22,3 ± 1,7 anos e IMC 21,4 ± 1,3 kg/cm2) foram divididas aleatoriamente em quatro grupos: (1) controle, (2) aquecimento, (3) alongamento, (4) aquecimento + alongamento. A atividade eletrica dos isquiotibiais foi captada por eletromiografia de superficie durante uma perturbacao subita do joelho. Um eletrogoniometro detectou o inicio da variacao angular, enquanto os eletrodos captaram o inicio e a amplitude da atividade muscular antes e apos as intervencoes. Como procedimento estatistico utilizou-se ANOVA two-way e post-hoc de Tukey, considerando-se como nivel de significância p < 0,05.RESULTADOS: O TLM do biceps femoral e do semitendineo foi reduzido nos grupos 3 (p = 0,048 e 0,027, respectivamente) e 4 (p = 0,026 e 0,039, respectivamente). Nao houve alteracao significativa da amplitude de ativacao muscular nos grupos avaliados.CONCLUSOES: Os dados do presente estudo sugerem que, embora nao tenham sido observadas alteracoes na amplitude eletromiografica, o alongamento passivo e estatico, utilizado de forma isolada ou associado ao aquecimento, promoveu uma reducao do TLM dos isquiotibiais. Essa reducao pode vir a ser um fator de protecao de lesoes musculares e articulares, apos uma perturbacao subita, como as que ocorrem na pratica desportiva.INTRODUCTION: The preparation for sports activities often involves warm-up and/or stretching in order to prevent injuries and/or improve performance. However, how these practices may interfere with neuromuscular mechanisms of joint control is unclear. OBJECTIVE: To analyze the immediate effect of stretching and warm-up exercises, alone or combined, on muscle latency time (MLT) and hamstrings activation amplitude after sudden knee joint disturbances. METHODS: Sixty female volunteers (mean age 22.3±1.7 years, BMI 21.4±1.3kg/cm2) were randomly divided into four groups: (1) control, (2) warm-up, (3) stretching, (4) warm-up + stretching. Hamstrings electrical activity was recorded by surface electromyography during a sudden knee disturbance. An electrogoniometer detected the onset of angular variation, while electrodes recorded the onset and amplitude of muscle activity before and after interventions. Two-way ANOVA and post hoc Tukey were used in statistical analysis, considering a significance level of p<0.05. RESULTS: The MLT of the biceps femoris and semitendinosus muscles was reduced in groups 3 (p=0.048 and 0.027, respectively), and 4 (p=0.026 and 0.039, respectively). There was no significant change in the amplitude of muscle activation amplitude in the evaluated groups. CONCLUSIONS: The results of this study suggest that although no changes in electromyographic amplitude were observed, static and passive stretching used alone or in combination with warm-up, caused a reduction in the hamstrings MLT. This reduction may prove to be a protective factor for muscle and joint injuries, after a sudden disturbance, such as those that occur in sports.
