Electrical stimulation of the preoptic area (POA) interrupts the lordosis reflex, a combined contraction of back muscles, in response to male mounts and the major receptive component of sexual behavior in female rat in estrus, without interfering with the proceptive component of this behavior or solicitation. Axon-sparing POA lesions with an excitotoxin, on the other hand, enhance lordosis and ...

OBJECTIVE Restoration of lumbar lordosis is a critical factor in long-term success after lumbar fusions. Transforaminal lumbar interbody fusion (TLIF) is a popular surgical technique in the lumbar spine, but few data exist on change in spinal alignment after the procedure. METHODS Eighty patients who underwent TLIF surgery were retrospectively reviewed (minimum follow-up period, 2 years). Sta...

Background Anterior cervical discectomy and fusion (ACDF) with a polyetheretherketone (PEEK) cage is considered as the gold standard for patients with cervical disc disease. However, there are limited in vivo data on the impact of ACDF on the cervical kinematics and its association with patient-reported clinical outcomes. The purpose of this study was to investigate the impact of altered cervic...

[Purpose] This study aimed to examine the effect of upper extremity training in the standing position on trunk alignment of patients with stroke. [Subjects and Methods] Twelve stroke patients were enrolled in the study and divided into two groups: a group of six patients in a sitting position and a group of six patients in a standing position. Upper extremity training for 30 min per day, five t...

[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...

OBJECTIVE To investigate the relationship between excursion of the diaphragm muscle and spinal curvatures in mouth breathing children. METHODS A total of 52 children of both sexes, aged from 5 to 12 years, were studied. After otorhinolaryngological assessment, the children were divided into two groups: mouth breathers and nose breathers. All of the children underwent videofluoroscopic examina...

STUDY DESIGN A cross-sectional case-control study was designed to compare the sagittal alignment of lumbosacral regions in two groups of patients suffering from low back pain, one with intervertebral disc pathologies and one without. PURPOSE To evaluate the correlation between lumbosacral sagittal alignment and disc degeneration. OVERVIEW OF LITERATURE Changes in lumbar lordosis and pelvic ...

The membrane actions of estrogens can facilitate their genomic actions. To determine whether this facilitation bears on CNS mechanisms for estrogen-dependent behaviors, ovariectomized rats were subjected to a two-pulse treatment of estrogen directly in the hypothalamic ventromedial nucleus. Two days later, each rat was given progesterone and then tested for lordosis behavior, the induction of w...

[Purpose] The aim of this study was to determine the effect of cervical posture manipulation, based on passive motion analysis (MBPMA) and general mobilization, on cervical lordosis, forward head posture (FHP), and cervical ROM in university students with problems in cervical posture and range of motion (ROM). [Subjects] The Subjects were 40 university students in their 20s who displayed proble...

OBJECTIVE To determine the association between advanced pelvic organ prolapse and changes in lumbar lordosis and/or pelvic inlet orientation. METHODS Lateral lumbosacral spine/pelvic x-rays were taken of women with grade 2 or greater uterovaginal prolapse and women with grade 1 or less prolapse standing in their usual upright posture. The angles of lumbar lordosis and the pelvic inlet were me...
