Kinesio Taping effects on knee extension force among soccer players

Background : Kinesio Taping (KT) is widely used, however the effects of KT on muscle activation and force are contradictory. Objective : To evaluate the effects of KT on knee extension force in soccer players. Method: This is a clinical trial study design. Thirty-four subjects performed two maximal isometric voluntary contractions of the lower limbs pre, immediately post, and 24 hours after tape application on the lower limbs. Both lower limbs were taped, using K-Tape and 3M Micropore tape randomly on the right and left thighs of the participants. Isometric knee extension force was measured for dominant side using a strain gauge. The following variables were assessed: peak force, time to peak force, rate of force development until peak force, time to peak rate of force development, and 200 ms pulse. Results : There were no statistically significant differences in the variables assessed between KT and Micropore conditions (F=0.645, p=0.666) or among testing sessions (pre, post, and 24h after) (F=0.528, p=0.868), and there was no statistical significance (F=0.271, p=0.986) for interaction between tape conditions and testing session. Conclusion: KT did not affect the force-related measures assessed immediately and 24 hours after the KT application compared with Micropore application, during maximal isometric voluntary knee extension. .

Evaluation of clinical and functional abnormalities in Pompe disease: Case Report / Avaliação das anomalias clínico-funcionais na doença de Pompe: Relato de Caso

The patient was a 15 year-old girl who turned out at the Physical Therapy Clinic presenting progressiv escoliosis and angle of 50º Coob by X-Ray. She complained of back pain, headache and weakness of shoulder and pelvic girdle. Physical therapy evaluation came across features of delayed motor development and undernourishment, together with generalized muscle weakness (grade = 4) which was observed by the Kendall test. Lung vital capacity was 40.5%. Clinical Changes: studies of the enzymes with acid alpha-glucosidase assay kits used on filter paper and leukocytes showed low enzyme activity, suggesting a late form of the Pompe disease. The molecular studies proved that the patient had amutation associated with late-onset Pompe disease. Acid alpha-glucosidase enzyme assay studies performed in skin fibroblasts showed a reduction of the enzymatic activity of the acid alpha-glucosidase, confirming the previous results. On account of the results, Pompe disease induced important changes inclinical and functional, as well as metabolic changes, decreased strength and muscle action potentially, biomechanical changes in the spine and changes in respiratory capacity. Furthermore, this case of Pompe disease illustrates the importance of adequate physical therapy evaluation as it can be the starting point of investigation of serious conditions such as late onset Pompe disease

Paciente do sexo feminino com 15 anos, apresentou-se na Clínica de Fisioterapia, devido à presença de escoliose progressiva com ângulo de Coob de 50º pelo Raio-X. Apresentou queixa de dor na coluna e na cabeça, fraqueza de cintura escapular e pélvica. Na avaliação fisioterapêutica observou-se um quadro semelhante ao atraso do desenvolvimento motor e desnutrição, com fraqueza muscular generalizada(grau = 4) observada pelo teste de Kendall. Na função pulmonar a capacidade vital apresentou com 40,5%. Estudos enzimáticos com dosagem da alfa-glicosidade ácida em papel-filtro e leucócitos evidenciaram baixa atividade enzimática, sugestivo de forma tardia da doença de Pompe. No estudo molecular, comprovou-se que a paciente possuía mutação associada à forma tardia da doença; estudos enzimáticos da alfa-glicosidase ácida em fibroblastos cultivados a partir de biópsia de pele evidenciaram redução da atividade enzimática da alfa-glicosidase ácida, confirmando estudos enzimáticos prévios. Perante os resultados, a doença de Pompe apresentou alterações clínicas e funcionais importantes como alteração do metabolismo, diminuição de força e do potencial de ação da musculatura, alterações biomecânicas na coluna e na capacidade respiratória. Adicionalmente, o caso ilustra a importância da avaliação fisioterapêutica adequada, pois ele pode ser o ponto de partida da investigação de doenças graves como o presente caso

Avaliação do efeito da hipotermia por crioimersão corporal, nos neutrófilos e linfócitos sanguíneos de ratos submetidos ao exercício físico agudo / Evaluation of the effect of hypothermia by cold water immersion on blood neutrophils and lymphocytes of rats submitted to acute exercise

O estresse sistêmico induzido pelo exercício libera substâncias bioativas determinantes da mobilização neutrofílica. A crioterapia diminui a reação inflamatória e atenua a elevação da perfusão sanguínea induzida pelo exercício. O objetivo deste trabalho foi analisar a influência da hipotermia decorrente da crioimersão corporal (CIC) imediata ao esforço físico agudo nas concentrações neutrofílicas e linfocíticas no sangue. Os ratos do grupo controle (AI) foram mantidos em repouso enquanto os do grupo AII foram submetidos ao protocolo de CIC a 10ºC por 10 minutos. Enquanto os animais dos grupos BI, BII, BIII e BIV realizaram o esforço físico agudo (EFA) em água a 31ºC durante 100 minutos com sobrecarga corpórea de 5% do peso corporal, os dos grupos CI, CII, CIII e CIV foram submetidos ao EFA seguido imediatamente de CIC. Nos grupos B e C, os animais foram sacrificados nos períodos de 06 (I), 12 (II), 24 (III) e 48 (IV) horas posteriores ao EFA. Através da microscopia óptica realizou-se a contagem dos neutrófilos e linfócitos. Utilizou-se do Teste T Student para análise estatística considerando-se nível de significância p < 0,05. Observou-se uma significativa neutrofilia nos grupos AII, BI, BII, BIII, BIV, CI, CII e CIII em relação a AI, diferentemente do grupo CIV, que apresentou quantidade de neutrófilos igual ao grupo controle. Os valores de linfócitos nos grupos BII, BIII, BIV, CI e CII foram significativamente menores do que AI, e nos grupos AII, BI, CIII e CIV foram iguais a AI. A neutrofilia e a linfopenia posteriores ao intenso exercício agudo são mantidas por 48 horas ou mais, porém, mediante a aplicação da crioimersão corporal imediata ao exercício, são normalizadas em 24 horas.

Systemic stress induced by exercise increases bioactive substances in plasma which leads to neutrophilic mobilization. Cryotherapy causes a decrease in the inflammatory reaction and attenuates high blood perfusion after exercise. The objective of this work was to analyze the influence of cold water immersion (CWI) after acute exercise on neutrophil and lymphocyte mobilization. A control group of rats (AI) was kept at rest and a second group (AII) was submitted to CWI at 10º C for 10 minutes. The animals of Groups BI, BII, BIII and BIV were submitted to acute exercise which consisted in swimming in water at 31º C for 100 minutes with a load equivalent to 5% of the body weight. Groups CI, CII, CIII and CIV were submitted to CWI immediately after acute exercise. The animals were sacrificed at 6 (I), 12 (II), 24 (III) and 48 (IV) hours after the exercise and neutrophil and lymphocyte cells were counted for all groups by optic microscopy. The Student t-test was used for statistical analysis with a significance level of p< 0.05. A significant increase in the number of neutrophils was observed in Groups AII, BI, BII, BIII, BIV, CI, CII and CIII compared to AI. The neutrophil count of the CIV Group was similar to the Control Group. There was a significant drop in the number of lymphocytes in Groups BII, BIII, BIV, CI and CII when compared to Group AI. The lymphocyte count of Groups AII, BI, CIII and CIV were similar to the Control Group. The changes in neutrophil and lymphocyte counts caused by acute exercise were reverted to normal at 24 hours by cold water immersion.
