Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...

OBJECTIVE To assess the level of functional capacity in subjects aged 60 years and older, who have lower back pain, and its association with demographic, socioeconomic, work-related, lifestyle-related and disease mentioned variables. METHODS A cross-sectional study was conducted with 246 elderly registered at the Family Health Strategy of Vila São Paulo, Bauru,SP, Brazil, who reported lower b...

OBJECTIVE To determine the prevalence of low back pain in children and its relationship with gender, age, exercise practice and sedentary activities (time on TV and on computer and/or video game). METHODS We conducted a cross-sectional study with a sample of 1,461 students, being 754 males and 707 females enrolled in the 5(th) to 8(th) grades of all five local elementary schools of urban Ouri...

Back pain is ubiquitous in today's society and is particularly common during pregnancy. There are multiple factors contributing to these symptoms during pregnancy including pelvic changes as well as alterations to loading. Potential imaging modalities are limited during pregnancy due to the desire to limit ionizing radiation exposure to the fetus. Treatments are generally conservative, exercise...

BACKGROUND CONTEXT Recurrent low back pain (LBP) is a common and costly problem that might be related to increased spine loads in those with LBP. However, we know little about how the spine is loaded when those with LBP perform lifting exertions. PURPOSE Document spine loading patterns of patients with LBP performing symmetric and asymmetric lifting exertions compared with asymptomatic indivi...

Stooped work has been shown to be associated with the development of low back disorders, particularly those that affect the spinal intervertebral discs. Although several studies have been conducted to evaluate the effects of physical factors on disc health, little research has focused on the effect of prolonged stooped work on disc hydration- a critical component of disc health. The purpose of ...

Gurfinkel and colleagues (2006) recently found that healthy adults dynamically modulate postural muscle tone in the body axis during anti-gravity postural maintenance and that this modulation is inversely correlated with axial stiffness. Our objective in the present study was to investigate whether dynamic modulation of axial postural tone can change through training. We examined whether teache...

BACKGROUND The control of force and its between-trial variability are often taken as critical determinants of motor performance. Subjects performed isometric trunk flexion and extension forces without and with experiment pain to examine if pain yields changes in the control of trunk forces. The objective of this study is to determine if experimental low back pain modifies trunk isometric force ...

OBJECTIVE Several studies have investigated asymmetry and loading patterns in different spine pathologies, motor disorders, and other conditions; there is a lack of knowledge on these aspects in chronic low back pain (CLBP). The aim of this study was to analyse asymmetry and loading patterns in patients with nonspecific chronic low back pain (NCLBP) compared to normal individuals, during walkin...
