GOAL OF THE STUDY This study intends to develop a method of quantitative sagittal balance parameters assessment, based on a geometrical model of lumbar spine and sacrum. METHODS One hundred eight patients were divided into 2 groups. In the experimental group have been included 59 patients with lumbar spinal stenosis on L1-5 level. Forty-nine healthy volunteers without history of any lumbar sp...

Posture assessment during childhood and adolescence allows early detection of postural disorders and adoption of preventive measures. This study evaluated the occurrence of lumbar hyperlordosis and associated factors in 467 children and adolescents aged 10 to 16 years at a school in Porto Alegre, Rio Grande do Sul State, Brazil. Lumbar hyperlordosis was defined as increased lumbar curvature eva...

Upright walking absent a bent-hip-bent-knee gait requires lumbar lordosis, a ubiquitous feature in all hominids for which it can be observed. Its first appearance is therefore a central problem in human evolution. Atelids, which use the tail during suspension, exhibit demonstrable lordosis and can achieve full extension of their hind limbs during terrestrial upright stance. Although obviously h...

UNLABELLED A physiologic sagittal alignment of the spine with lumbar lordosis and thoracic kyphosis is the most stable position of the spine, while in patients with Idiopathic Scoliosis (IS) the sagittal profile of the spine is flattened or inversed. It has been shown that a correction of the sagittal profile also corrects coronal plane deformity in patients with IS. Therefore sagittal correcti...

Introduction: Elongation exercises are designed to reduce existing pathological or increased physiological curvatures of the spine. The aim of the study was to evaluate the changes occurring in the parameters describing the anterior-posterior spinal curvatures during the performance of symmetric elongation exercises. Material and methods: The study included 150 children aged 7–10 years: 82 girl...

[Purpose] This study developed a modified active leg-raising exercise to decrease lumbar lordosis and assessed its effectiveness in a patient with low back pain and excessive lumbar lordosis. [Subject and Methods] The subject was a 56-year-old woman with excessive lordosis, who complained of continuous severe LBP pain at the L5 level for 1 year. The subject performed the modified active leg-rai...

The purpose of this cross-sectional study was to examine mean values of isometric torso muscle profiles of four spinal postures (good posture, thoracic kyphosis, lumbar lordosis and scoliosis) among 743 children from the ages of 7 to 14 years old. It was hypothesized that having good posture, thoracic hyper-kyphosis, lumbar hyper-lordosis and scoliosis is linked to different isometric torso mus...

The lordosis reflex is a hormone-dependent behavior displayed by female rats during mating. This study used the transneuronal tracer pseudorabies virus (PRV) to investigate the CNS network that controls the lumbar epaxial muscles that produce this posture. After PRV was injected into lumbar epaxial muscles, the time course analysis of CNS viral infection showed progressively more PRV-labeled ne...
