“…Although a preliminary study with a small sample, the results show that the clinical outcomes of pain and disability have excellent correlation (r=0.82; p<0.01) and is in accordance with expectations from the clinical point of view and with the literature 25 . Similarly, the STarT Back questionnaire of our sample for low and medium risk for poor prognosis correlated moderately with pain and disability (r=0.68 and r=00:57, respectively).…”

RESUMO Este estudo investigou a associação entre testes clínicos, desfechos clínicos e risco prognóstico de pacientes com dor lombar crônica não específica. Para esta pesquisa, 20 pacientes, maiores de 18 anos, foram selecionados por conveniência e submetidos à avaliação dos desfechos clínicos por meio de Escala numérica de dor e Questionário de incapacidade. Para classificação de risco prognóstico utilizou-se o questionário STarT Back, e para avaliar o recrutamento do músculo transverso do abdome foram utilizados os seguintes testes clínicos: Escala de classificação clínica (ECC); e medida da espessura dos músculos do abdome por meio de imagens ultrassonográficas (MEM-US). Os testes foram realizados em um único dia por avaliador treinado, e a ordem dos testes foi aleatória. Os coeficientes de correlação de Pearson (r) e Spearman (rS) foram utilizados para investigar a associação. Os resultados mostraram que as associações entre o risco prognóstico de dor lombar com os desfechos clínicos, dor e incapacidade foram moderadas (r=0,68 e r=0,57, respectivamente). Para ECC, as associações com incapacidade e risco prognóstico foram consideradas razoáveis (r=-0,34 e r=-0,36, respectivamente). Não houve associações com a MEM-US. Na amostra de baixo risco prognóstico, a relação do ECC com a incapacidade foi considerada moderada para boa, enquanto para dor a correlação foi razoável (rS=-0,62 e rS=-0,24, respectivamente). Concluímos que existe associação entre ECC com desfechos clínicos e risco prognóstico, e a estratificação, segundo o risco prognóstico, aumenta a relação observada. Futuros estudos devem ser conduzidos com novas medidas para avaliação do recrutamento muscular abdominal com amostras maiores.

“…Utilities were estimated from mean pain VAS scores for the two treatment arms, using a relationship between pain VAS and EQ-5D utility sourced from a study of back pain. 137 The latter gave a much steeper gradient in utility loss with increasing pain than that derived from a study of varicose veins (a utility decrement of 0.035 per 1% increase in pain VAS compared with 0.0026; 86 see Utility values), suggesting that the QALY benefit of RFA compared with surgery reported by Adi et al 135 may be overestimated by over 10 times. Costs were taken from the Finnish trial.…”

“…The suggestion that the number of fractures is also an important determinant of the worsening of quality of life has been supported by the observation that the impact of any recent vertebral fracture is more marked in the patients who had already sustained a previous vertebral deformity [5]. Moreover, it is important to note that in elderly women, back pain is multifactorial and is often the result of osteoarthritis, a protruded disk, and muscle diseases [18,33]. In our study population, we found that reduced values of stiffness are associated to a lowering of health-related quality of life; however, the association was no longer significant after adjusting for potential confounders such as age, comorbidities, and fractures.…”

Background Osteoporosis, a multifactorial systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue leading to increased bone fragility, is a worldwide public health problem. Vertebral fractures affect approximately 20% of postmenopausal women and are a hallmark of osteoporosis, but they may pass unnoticed, although they may lead to long-term immobility and disability. Questions/purposes The aims of the present study were (1) to determine the prevalence and the severity of vertebral fractures in a large cohort of Italian women aged 60 years or older with reduced values of quantitative ultrasound parameters; and (2) to assess whether vertebral fractures and other variables may be associated with health-related quality of life. Methods A total of 2450 women without back pain aged 60 years or older, after the completion of the Quality of Life Questionnaire of the European Foundation for Osteoporosis QUALEFFO, underwent quantitative ultrasound evaluation of the calcaneus; in those with a stiffness t-score of B À2 (n = 1194), radiographic evaluation of the thoracic and lumbar spine was carried out and then quantitative morphometry was performed by dedicated software (MorphoXpress). The radiographic analysis was carried out on 885 women who presented films of adequate quality. Multivariate regression was used to adjust for confounding variables. Results Of those who underwent radiographic analysis, 681 had no vertebral fractures, and 204 women (23.1%) had one or more previously undiagnosed vertebral fractures. The prevalence of previously undiagnosed vertebral fractures increased with advancing age with more than 30% of women older than 75 years having at least one fracture. Older age, body mass index, and severe vertebral fractures were independently associated with a worse total QUALEFFO score. Conclusions We found that approximately one in four women showed evidence of undiagnosed vertebral fractures, and there was a strong age effect trend. Moreover, the severity grade of vertebral fractures, more than the number of fractures, was associated with a worsening of healthrelated quality of life as assessed by QUALEFFO. These findings confirm the clinical relevance of an early diagnosis of vertebral fractures and seem to support the usefulness of quantitative ultrasound measurements in the stratification of postmenopausal women at increased fracture risk.
