RESUMO

Pontos-gatilho são nódulos musculares que podem desenvolver dor. A dor lombar é um importante problema de saúde pública e estudos apontam que todas as pessoas que sofrem de dor na coluna apresentam ponto-gatilho. Objetivo: Analisar o nível dor de pacientes com dor lombar aguda que quando assintomáticos apresentava pontos-gatilho latente, comparado com os níveis de dor de pacientes com dor lombar aguda que quando assintomáticos não apresentava pontos-gatilho. Método:96 indivíduos de ambos os sexos entre 18 -60 anos participaram de um estudo transversal com avaliador cego. Foram analisados o nível de dor, função, atividade física, cinesiofobia, algometria e mensurada a força do músculo glúteo máximo e médio do membro dominante e não-dominante, no memento que os participantes estavam assintomáticos e após desenvolverem dor lombar aguda. Para análise estatística consideramos valores de significância igual ou menor que 0,05. Resultados: Foi observado diferenças significativas entre os grupos na intensidade da dor (p=0,01), na funcionalidade (p=0,02), na algometria (p=0,00), na dinamometria do músculo glúteo máximo do membro não-dominante (p=0,05) e da dinamometria do glúteo médio do membro dominante (p=0,01) e não-dominante (p=0,00). Conclusão: Indivíduos assintomáticos com pontos-gatilho latente nos músculos paravertebrais lombares apresentam pior intensidade da dor e outros desfechos quando evoluem dor lombar aguda, comparados com indivíduos que não apresentam pontos-gatilho no momento que estão assintomáticos

Trigger points are muscle nodules that can lead to pain. Low back pain is an important problem of public health and studies point out all the people who suffer from spinal pain present trigger points. Objective: To analyze the pain level of the asymptomatic patients, with acute low back pain, who present latent trigger point, when compared to the pain level of the asymptomatic patients with acute low back pain who did not present latent trigger point. Method:96 individuals of both genres, aged 18 to 60 years took part in a transversal, evaluator-blind study. Level pain, function, physical activity, kynesiophobia, algometer were analyzed and the gluteus maximus and gluteus medius muscles' strength of the dominant limb and non-dominant were measured, at the moment the participants were asymptomatic and after developing acute back low pain. For statistical analysis, we considered significant value ≤ 0.05 Results: It was observed significant differences between the groups in relation to pain intensity (p=0.01), functionality (p=0.02), algometer (p=0.05), gluteus maximus muscle dynamometry of the non-dominant limb (p=0.05) and in the gluteus medius muscle of the dominant limb (p=0.01) and non-dominant (p=0.00). Conclusion: Asymptomatic individuals with latent trigger points in the paravertebral lumber muscles present worse pain intensity and other outcomes when it evolves to acute back pain if compared to individuals who don't present trigger points at the moment they, are considered asymptomatic.

RESUMO

BACKGROUND: The STarT Back Screening Tool (SBST) is used to stratify care. It is unclear if the SBST approach works as well for patients in low- and medium-income countries as for patients from high-income countries. OBJECTIVES: (1) To investigate whether patients with chronic low back pain (LBP) stratified by the SBST are different at baseline; (2) to describe the clinical course for each SBST subgroup; (3) to investigate the SBST utility to predict clinical outcomes; and (4) to determine which SBST subgroup show greater clinical improvement. DESIGN: This is a secondary analysis of data derived from a previously published clinical trial. METHODS: 148 patients with chronic nonspecific LBP were included. Pain intensity, disability, global perceived effect, and the SBST were assessed at baseline and at 5, 12, and 24 weeks after baseline. Descriptive data were provided and ANOVA, unadjusted and adjusted regression models, and linear mixed models were used for data analysis. RESULTS: Duration of symptoms, use of medication, pain, disability, and global perceived effect were different between SBST subgroups. Clinical improvements over a 6-month period were consistently greater in patients classified as high risk. The SBST was able to predict disability but this predictability decreased when the analysis was adjusted for possible confounders. CONCLUSION: Clinical outcomes were different between SBST subgroups over 6 months. Adjusting for confounders influenced the predictability of SBST. Patients classified as high risk presented higher improvements in terms of disability.

RESUMO

BACKGROUND: Lymphedema is known as a secondary complication of breast cancer treatment, caused by reduction on lymphatic flow and lymph accumulation on interstitial space. The Kinesio Taping (KT) has become an alternative treatment for lymphedema volume reduction. The objective of the study was to evaluate the literature through a systematic review on KT effects on lymphedema related to breast cancer. METHODS: Search strategies were performed by the following keywords: "Kinesio Taping," "Athletic Tape," "Cancer," "Neoplasm," "Lymphedema," and "Mastectomy" with derivations and different combinations. The following databases were accessed: SCIELO, LILACS, MEDLINE via PubMed, and PEDro, between 2009 and 2016. Studies published in English, Portuguese, and Spanish were considered for inclusion. The studies' methodological quality was assessed by the PEDro scale. RESULTS: Seven studies were identified by the search strategy and eligibility. All of them showed positive effect in reducing lymphedema (perimeter or volume) before versus after treatment. However, with no effects comparing the KT versus control group or others treatments (standardized mean difference = 0.04, confidence interval 95%: -0.24; 0.33), the average score of the PEDro scale was 4.71 points. CONCLUSIONS: KT was effective on postmastectomy lymphedema related to breast cancer; however, it is not more efficient than other treatments.

RESUMO

The objective of this study was to observe the immediate effect of a knee brace with a patellar hole versus without a patellar hole on pain perception in patients with knee osteoarthritis. To accomplish this, a double-blind, randomized controlled trial enrolled 108 patients divided into two groups (knee brace with a patellar hole or without a patellar hole). Patients were evaluated by the Visual Analogue Scale (VAS) in order to measure their pain sensation, the Timed Up and Go (TUG) test was used to evaluate their ability to walk, and the 8-m walking test (8MWT) was used to estimate their walking speed. Both groups presented significant reduction in pain perception, higher function of the lower extremities, and greater mobility while wearing a knee brace. However, the patients who wore a knee brace without a patellar hole presented more favorable results than those who wore a knee brace with a patellar hole: a 1.6-point reduction was found versus 1.1 points in the VAS, the patients presented 0.7 s less time versus 0.4 s in the TUG, and the speed was reduced by 1.4 s versus 0.8 s in the 8MWT. Therefore, the knee brace without a patellar hole presented more favorable results when compared with the knee brace with a patellar hole.
