OBJECTIVE To investigate the effect of sitting posture on lung capacity and expiratory flow (LC-EF) and lumbar lordosis. DESIGN Repeated measures on 1 group of subjects in 4 postures. SETTING Laboratory. PARTICIPANTS Seventy able-bodied volunteers. INTERVENTIONS Postures were assumed randomly: normal, with full ischial support and flat lumbar support; slumped, with the pelvis positioned...

Hypokyphosis is currently observed in thoracic idiopathic scoliosis. The use of sublaminar bands allows a good restoration of sagittal balance of the spine. The aim of the study was to provide a middle-term radiographic analysis of patients with adolescent idiopathic scoliosis with preoperative hypokyphosis treated by posterior arthrodesis with sublaminar bands. This retrospective study include...

BACKGROUND The minimally invasive lateral interbody fusion (MIS LIF) in the lumbar spine can correct coronal Cobb angles, but the effect on sagittal plane correction is unclear. METHODS A retrospective review of thirty-five patients with lumbar degenerative disease who underwent MIS LIF without supplemental posterior instrumentation was undertaken to study the radiographic effect on the resto...

[Purpose] This study examined the effects of lumbar stabilization exercises on the functional disability and lumbar lordosis angles in patients with chronic low back pain. [Subjects] The subjects were 30 patients with chronic low back pain divided into a lumbar stabilization exercise group (n = 15) and a conservative treatment group (n = 15). [Methods] The lumbar stabilization exercise and cons...

Introduction. Three-column vertebral resections are frequently applied to correct sagittal malalignment; their effects on distant unfused levels need to be understood. Methods. 134 consecutive adult PSO patients were included (29 thoracic, 105 lumbar). Radiographic analysis included pre- and postoperative regional curvatures and pelvic parameters, with paired independent t-tests to evaluate cha...

INTRODUCTION Gynoid lipodystrophy (cellulite) has been cited as a common dermatological alteration. It occurs mainly in adult women and tends to gather around the thighs and buttocks. Its presence and severity have been related to many factors, including biotype, age, sex, circulatory changes, and, as some authors have suggested, mechanical alterations such as lumbar hyperlordosis. OBJECTIVE ...

BACKGROUND Loss of lumbar lordosis has been reported after lumbar interbody fusion surgery and may portend poor clinical and radiographic outcome. The objective of this research was to measure changes in segmental and global lumbar lordosis in patients treated with presacral axial L4-S1 interbody fusion and posterior instrumentation and to determine if these changes influenced patient outcomes....

STUDY DESIGN Analysis of positional magnetic resonance images of normal volunteers. OBJECTIVE To compare the reliability and precision of an active shape model to that of conventional lordosis measurements. SUMMARY OF BACKGROUND DATA Characterization of lumbar lordosis commonly relies on measurement of angles; these have been found to have errors of around 10 degrees . METHODS T2 weighted...

OBJECTIVE To determine if a new method of lumbar extension traction can increase lordosis in chronic low back pain (LBP) subjects with decreased lordosis. DESIGN Nonrandomized controlled trial with follow-up at 3 months and 1(1/2) years. SETTING Primary care spine clinic in Nevada. PATIENTS Beginning in mid-1998, the first 48 consecutive patients, who met the inclusion criteria of chronic...

STUDY DESIGN A cross-sectional, descriptive study. PURPOSE This study aimed to investigate the relationship between kyphosis and lordosis measured by using a flexible ruler and musculoskeletal pain in students of Hamadan University of Medical Sciences. OVERVIEW OF LITERATURE The spine supports the body during different activities by maintaining appropriate body alignment and posture. Normal...
