Neural management plus advice to stay active on clinical measures and sciatic neurodynamic for patients with chronic sciatica: Study protocol for a controlled randomised clinical trial.

Advice to stay active is the primary management strategy for sciatica. Other conservative treatments such as neural management techniques may also contribute to sciatica recovery, but currently, the effects have not been robustly assessed. Thus, the aim of this study is to compare the effects of adding neural management to advice to stay active versus advice to stay active alone in improving pain intensity and functional limitation. Secondarily, to compare the effects of the experimental intervention in the sciatic neurodynamic, pain modulation, and psychosocial factors. A parallel-group, controlled, examiner-blinded superiority clinical trial randomised at a 1:1 allocation will be conducted in 210 participants with chronic sciatica. Patients will be recruited from outpatient physiotherapy clinics and community advertisements. The experimental group will receive neural mobilisation techniques and soft tissue mobilisation techniques for 30 minutes per session, 10 weekly sessions, plus advice to stay active on their activities of daily living, information on physical activity, imaging tests, and sciatica for 5 biweekly sessions lasting 25-30 minutes. The control group will receive advice to stay active only. The re-evaluation will be performed out after 5 weeks, 10 weeks, and 26 weeks after randomisation and primary endpoints will be pain intensity and functional limitation at 10 weeks. Secondary outcomes will include neuropathic symptoms, sciatic neurodynamic, pain modulation, and psychosocial factors. Adverse events and patient satisfaction will be assessed. Ethical approval has been granted from an Institutional Human Research Ethics Committee. Trial registration: Trial was prospectively registered in the Brazilian Registry of Clinical Trials (number: RBR-3db643c)

High prevalence of inadequate sitting and sleeping postures: a three-year prospective study of adolescents

Abstract There is a paucity of information regarding the development of body posture during adolescence. This three-year prospective study aimed to evaluate sitting and sleeping postures among adolescents, and to determine whether these postures are associated with age and sex. We assessed 525 adolescents aged 11–16 years from the fifth to eighth grades. These adolescents were reassessed three years later. The Back Pain and Body Posture Evaluation Instrument was used to evaluate the sleeping posture and three sitting positions: sitting to write, to use a computer, and during leisure activities. Our findings indicated a low prevalence of adequate sleeping and sitting postures at baseline, with a decrease in prevalence observed after three years for all postures. These changes were similar for both sexes. Moreover, we found a strong reduction of adequate posture prevalence for younger adolescents, but the oldest adolescents demonstrated no significant differences after three years. Early, rather than late, adolescence is a critical period for establishing inadequate sitting and sleeping postures. This has implications for posture throughout adulthood; hence, interventions targeted at this age group are needed

Invalidez por dor nas costas entre segurados da Previdência Social do Brasil

OBJETIVO: Descrever as aposentadorias por invalidez decorrente de dor nas costas. MÉTODOS: Estudo descritivo com dados do Sistema Único de Informações de Benefícios e dos Anuários Estatísticos da Previdência Social em 2007. A taxa de incidência de dor nas costas como causa das aposentadorias por invalidez foi calculada segundo as variáveis idade e sexo, nos estados. Os dias de trabalho perdidos por invalidez decorrente de dor nas costas foram calculados segundo atividade profissional. RESULTADOS: A dor nas costas idiopática foi a primeira causa de invalidez entre as aposentadorias previdenciárias e acidentárias. A maioria dos beneficiários residia em área urbana e era comerciário. A taxa de incidência de dor nas costas como causa das aposentadorias por invalidez no Brasil foi de 29,96 por 100.000 contribuintes. Esse valor foi mais elevado entre os homens e entre as pessoas mais velhas. Rondônia exibiu taxa quatro vezes superior ao esperado (RT = 4,05) e a segunda maior taxa, referente à Bahia, foi de aproximadamente duas vezes o esperado (RT = 2,07). Os comerciários foram responsáveis por 96,9% dos dias perdidos por invalidez. CONCLUSÕES: A dor nas costas foi uma importante causa de invalidez em 2007, sobretudo entre comerciários, com grandes diferenças entre os estados.OBJECTIVE: To describe disability pension from back pain. METHODS: Descriptive study based on data from the Brazilian Social Security Beneficiary Database and the Social Security Statistics Annual Report in 2007. The incidence rate of disability pension from back pain was estimated according to gender and age by Brazilian states. There were also estimated working days lost due to back pain disability by occupation. RESULTS: Idiopathic back pain was the most common cause of disability among social security pension and accidental retirement. Most pensioners were living in urban areas and were commercial workers. The rate of disability pension from back pain in Brazil was 29.96 per 100,000 beneficiaries. A higher rate was seen among males and older individuals. Rondônia showed the highest rate, four times as high as expected (RR= 4.05) followed by Bahia with a rate about twice as high as expected (RR=2.07). Commercial workers accounted for 96.9% of working days lost due to disability. CONCLUSIONS: Back pain was a major cause of disability in 2007 mostly among commercial workers showing great differences between the Brazilian states.OBJETIVO: Describir las jubilaciones por invalidez producto del dolor en la espalda. MÉTODOS: Estudio descriptivo con datos del Sistema Único de Informaciones de Beneficios y de los Anuarios Estadísticos del Seguro Social en 2007. La tasa de incidencia de dolor en la espalda como causa de jubilaciones por invalidez fue calculada según las variables edad y sexo, por Unidades Federativas de Brasil. Los días de trabajo perdidos por invalidez producto del dolor en la espalda fueron calculados según actividad profesional. RESULTADOS: El dolor idiopático en la espalda fue la primera causa de invalidez entre las jubilaciones sociales y accidentales. La mayoría de los beneficiarios residía en área urbana y trabajaba en el comercio. La tasa de incidencia de dolor en la espalda como causa de las jubilaciones por invalidez en Brasil fue de 29,96 por 100.000 contribuyentes. Este valor fue más elevado entre los hombres y entre las personas más viejas. Rondonia (Norte de Brasil) exhibió una tasa mayor de cuatro veces lo esperado (RT=4,05) y la segunda mayor tasa, referente a Bahia (Noreste), fue de aproximadamente dos veces lo esperado (RT=2,07). Los trabajadores del comercio fueron responsables de 96,9% de los días perdidos por invalidez. CONCLUSIONES: El dolor de espalda fue una causa importante de invalidez en 2007, sobretodo entre los trabajadores del comercio, con grandes diferencias entre los estados
