Intensity level for exercise training in fibromyalgia by using mathematical models

Background: It has not been assessed before whether mathematical models described in the literature for prescriptions of exercise can be used for fibromyalgia syndrome patients. the objective of this paper was to determine how age-predicted heart rate formulas can be used with fibromyalgia syndrome populations as well as to find out which mathematical models are more accurate to control exercise intensity.Methods: A total of 60 women aged 18-65 years with fibromyalgia syndrome were included; 32 were randomized to walking training at anaerobic threshold. Age-predicted formulas to maximum heart rate (220 minus age and 208 minus 0.7 x age) were correlated with achieved maximum heart rate (HRMax) obtained by spiroergometry. Subsequently, six mathematical models using heart rate reserve (HRR) and age-predicted HRMax formulas were studied to estimate the intensity level of exercise training corresponding to heart rate at anaerobic threshold (HRAT) obtained by spiroergometry. Linear and nonlinear regression models were used for correlations and residues analysis for the adequacy of the models.Results: Age-predicted HRMax and HRAT formulas had a good correlation with achieved heart rate obtained in spiroergometry (r = 0.642; p < 0.05). for exercise prescription in the anaerobic threshold intensity, the percentages were 52.2-60.6% HRR and 75.5-80.9% HRMax. Formulas using HRR and the achieved HRMax showed better correlation. Furthermore, the percentages of HRMax and HRR were significantly higher for the trained individuals (p < 0.05).Conclusion: Age-predicted formulas can be used for estimating HRMax and for exercise prescriptions in women with fibromyalgia syndrome. Karnoven's formula using heart rate achieved in ergometric test showed a better correlation. for the prescription of exercises in the threshold intensity, 52% to 60% HRR or 75% to 80% HRMax must be used in sedentary women with fibromyalgia syndrome and these values are higher and must be corrected for trained patients.Universidade Federal de São Paulo, São Paulo, BrazilUniv Fed Espirito Santo, Vitoria, BrazilUniversidade Federal de São Paulo, São Paulo, BrazilWeb of Scienc

Impacto inicial da órtese para polegar em botoeira

OBJECTIVE: To evaluate the use of a static positioning orthesis for boutonnière deformity on the thumb. METHODS: Twenty women aged between 25 and 74 years old were included in the study. They were distributed at random into a control group and a group using orthesis. Pinch and Jamar's dynamometers, Pain Visual Scale and O'Connor's Functional Evaluation were applied to all patients. Wilcoxon's, Mann Whitney's and Scheffe's tests were used for the statistical analysis. RESULTS: After 30 days in the intra-group analysis, there was functional improvement, evaluated by O'Connor's test in 40% of the controls and 70% of these patients using orthesis. There was no statistically significant difference between the groups in any of the evaluated parameters. CONCLUSIONS: These results suggest that orthesis is beneficial to the functional improvement; the tested model was comfortable and well accepted by patients. Nevertheless, subsequent studies of longer duration and including more subjects are needed.OBJETIVO: avaliar o uso de uma órtese estática de posicionamento para a deformidade em botoeira no polegar. MÉTODOS: foram incluídas mulheres com idade entre 25 e 74 anos e distribuídas de modo aleatório em grupo controle ou grupo usando órteses. Os instrumentos de avaliação utilizados foram os dinamômetros Pinch e Jamar, a escala visual de dor e o teste funcional de O'Connor. Na análise estatística foram utilizados os testes de Wilcoxon, de Mann Whitney e de Scheffe. RESULTADOS: após 30 dias, na análise intragrupo houve uma melhora funcional, como medido pelo teste de O'Connor, em 40% do controle e 70% dos pacientes que usaram órteses. Não houve diferença estatisticamente significante entre os grupos em nenhum dos parâmetros avaliados. CONCLUSÕES: esses resultados sugerem que a órtese é benéfica na melhora funcional e o modelo testado foi confortável e bem tolerado pelos pacientes. Porém, é necessário um estudo subseqüente, mais extenso e incluindo maior número de pacientes.UNIFESP-EPMUNIFESP-EPM Rheumatology Rehabilitation SectionUNIFESP, EPM, Rheumatology Rehabilitation SectionSciEL

Qualidade de vida em pacientes com osteoporose: correlação entre OPAQ e SF-36 Quality of life in patients with osteoporosis: correlation between OPAQ and SF-36

OBJETIVO: correlacionar o instrumento de avaliação de qualidade de vida específico para osteoporose, o Osteoporosis Assessment Questionnaire (OPAQ), com o instrumento genérico, o The Medical Outcomes Study 36 - Item Short Form Health Survery (SF-36). PACIENTES E MÉTODOS: estudo observacional de corte transversal que incluiu 40 mulheres acima de 60 anos, diagnosticadas com osteoporose. Houve um momento para avaliação e um único examinador. Para a análise estatística foram utilizados coeficiente correlação de Pearson e análise fatorial do OPAQ. RESUTADOS: houve correlação entre os domínios e componentes finais do SF-36 com os domínios do OPAQ. Evidenciou-se que os coeficientes mais altos foram entre o OPAQ Sintomas e os seguintes domínios do SF-36: dor (r=-0,6), aspectos sociais (r=-0,6%) e saúde mental (r=-0,5). Quase todos os aspectos do SF-36 se correlacionaram com o OPAQ Sintomas. E, ainda, por análise fatorial do OPAQ, observa-se que os seus 18 componentes representaram 63% de carga fatorial, ou seja, eles explicaram o valor total de impacto da osteoporose na qualidade de vida e agruparam-se em cinco fatores: fator 1 (mobilidade, cuidados próprios, independência e trabalho doméstico), fator 2 (flexibilidade, movimentação e sono), fator 3 (dor nas costas, dor relacionada à osteoporose, fadiga e humor), fator 4 (medo de cair, atividades sociais, apoio familiar e tensão) e fator 5 (andar-inclinar, imagem corporal e trabalho). CONCLUSÃO: foi encontrada a correlação esperada entre SF-36 e OPAQ, que é um instrumento de avaliação específico com capacidade para avaliar aspectos específicos e gerais da qualidade de vida nesta população.<br>OBJECTIVE: to correlate the quality of life assessment instrument, specific to osteoporosis, OPAQ (Osteoporosis Assessment Questionnaire), with the generic instrument SF-36 (Item Short Form Health Survey). PATIENTS AND METHODS: the cross sectional observational study included 40 female patients older than 60 years with osteoporosis. A single assessment was always conducted by the same evaluator. For the statistics analisys the Pearson’s coefficient and the factor analysis to OPAQ were used. RESULTS: there was a correlation between the domains and final components of SF-36 with the domains of OPAQ. The higher coefficients were between the OPAQ Symptoms and some domains of SF-36: pain (r=-0,6), social aspects (r=-0,6) and mental health (r=-0,5). Almost every aspect of SF-36 was correlated with the OPAQ Symptoms. By factor analysis of OPAQ it was observed that the 18 components of OPAQ represented 63% of factor load, and they explained the total account of osteoporosis’s impact in the quality of life and were grouped in five factors: factor 1 (mobility, self-care, independence and household tasks), factor 2 (flexibility, transfers and sleep), factor 3 (backache, pain related to osteoporosis, fatigue and mood), factor 4 (fear of fall, social activity, family support and tension) and factor 5 (walking and bending, body image and work). CONCLUSION: the expected correlation was achieved between SF-36 and OPAQ, wich is a specific assessment instrument capable of assessing particular and general aspects of the quality of life in patients with osteoporosis
