ABSTRACT

Abstract BACKGROUND: Among the chronic leg ulcers, venous ulcers are the most common and constitute a major burden to public health. Despite all technology available, some patients do not respond to established treatments. In our study, carboxymethylcellulose was tested in the treatment of refractory chronic venous ulcers. OBJECTIVE: To evaluate the efficacy of carboxymethylcellulose 20% on the healing of chronic venous ulcers refractory to conventional treatments. METHODS: This is an analytical, pre-experimental study. Thirty patients were included with refractory venous ulcers, and applied dressings with carboxymethylcellulose 20% for 20 weeks. The analysis was based on measurement of the area of ulcers, performed at the first visit and after the end of the treatment. RESULTS: There was a reduction of 3.9 cm2 of lesion area (p=0.0001), corresponding to 38.8% (p=0.0001). There was no interruption of treatment and no increase in lesion area in any patient. CONCLUSIONS: Carboxymethylcellulose 20% represents a low cost and effective therapeutic alternative for the treatment of refractory chronic venous ulcers. However, controlled studies are necessary to prove its efficacy.

ABSTRACT

Défices sensoriais persistentes após a reconstrução do ligamento cruzado anterior (LCA) podem causar alterações como fraqueza muscular e comprometimento do equilíbrio e do desempenho funcional. Diversos estudos discutem se essas alterações também estão presentes no membro inferior não acometido e se esse membro pode ser utilizado como referência nas avaliações desses pacientes. O objetivo do presente estudo foi comparar o torque extensor e flexor do joelho, o equilíbrio unipodal e o desempenho funcional sobre o membro não-acometido de pacientes submetidos à reconstrução do LCA, com membros inferiores de sujeitos saudáveis. Participaram do estudo 23 indivíduos submetidos à reconstrução do LCA e 22 sujeitos saudáveis, que foram avaliados quanto ao torque extensor e flexor do joelho durante contração isocinética concêntrica a 60 graus/s no dinamômetro isocinético, à velocidade média de oscilação do centro de pressão em apoio unipodal no baropodômetro, e submetidos a dois testes de salto para avaliar o desempenho funcional. Os resultados não revelaram diferenças entre o membro não-acometido e os membros inferiores do grupo controle em todas as variáveis estudadas (p>0,05). Esses resultados sugerem que o membro não-acometido de pacientes submetidos à reconstrução do LCA pode ser utilizado como referência nos estudos de avaliação desses pacientes.


Persistent sensorial deficits after anterior cruciate ligament (ACL) reconstruction might lead to muscle weakness, balance and functional performance disorders. Several studies inquire whether these alterations also appear in the uninjured limb and whether the latter could be used as reference for patient assessment. The aim of the present study was to compare knee extensor and flexor torque, balance and functional performance of non-injured lower limb, after contralateral ACL reconstruction, with lower limbs of healthy subjects. Twenty three male patients who had had ACL reconstruction, and 22 control subjects were assessed as to knee flexor and extensor torque during concentric isokinetic contraction at 60o/s with an isokinetic dynamometer, mean speed of centre of pressure swing during single-limb stance, and submitted to two hop tests to assess functional performance. Results showed no significant differences between uninjured side and healthy subjects lower limbs at all assessed variables (p>0.05). These findings suggest that the uninjured limb may be safely used as reference in studies to assess post-ACL patients.

ABSTRACT

Introdução: Exercícios de alongamento são comumente usados precedendo a realização de atividades físicas, no entanto, pesquisas recentes têm sugerido uma redução da força muscular após o alongamento. Objetivo: O objetivo deste estudo foi observar o efeito agudo de três técnicas de alongamento muscular sobre o torque flexor do joelho, produzido pelos músculos ísquiotibiais. Método: Sessenta mulheres jovens, saudáveis, (idade média de 22,S ± 3 anos), com encurtamento clínico dos ísquiostibiais, foram alocadas aleatoriamente em 4 grupos: controle, alongamento estático, manter-relaxar, e agonista-manter-relaxar. Todas foram submetidas a um protocolo de avaliação no qual realizaram 5 contrações concêntricas máximas de flexão/extensão do joelho a 600/s antes e após a aplicação do respectivo alongamento, o qual teve duração média de um minuto. O grupo controle permaneceu 5 minutos em repouso. Os dados foram analisados estatisticamente e o nível de significância foi atribuído em 5%. Resultados: Não foi identificada diferença entre os grupos antes nem depois da intervenção. Também não houve diferença intragrupo após a intervenção. Conclusão: Os resultados sugerem que o alongamento da musculatura posterior da coxa, com duração média de um minuto, não provoca modificações imediatas no torque flexor do joelho.


Introduction: Stretching exercises are commonly used prior to physical activities, however, recent researchs identified reduction of muscle strength post-stretching. Objective: The aim of this study was to observe the acute effect of three techniques of muscle stretching on torque produced by hamstrings on the knee. Method: Sixty women, healthy, mean age 22.55 ± 3.04 years, with shortening hamstrings, were randomly distributed into 4 groups (control, static stretching, hold-relax, and agonist-hold-relax). They were submitted to evaluation protocol in which performed 5 maximal concentric contractions of knee flexion/extension at 60°/s before and after the application of stretching technique, which had total duration about 48-60s, depending on the group. The control group remained at rest 5 minutes. The data were statistically analyzed and the levei of significance set at 5%. Results: No difference was detected between groups before or after the intervention. There was no intragroup difference after the intervention in any of the groups. Conclusion: The results suggest that the muscle stretching, lasting up to 60 seconds does not cause acute changes in the knee flexion torque.
