Sensory and Hypothalamic Control of Lordosis Behavior in Female Rodents
<p>When applied during the sustained lordosis response of female hamsters, gentle probing at points on the perineal surface elicited stereotyped rump and tail movements. The rump movements always served to rapidly center the vaginal opening beneath the continuing stimulation. Tail deflections were …

The Effect of Hamstring Lengthening on Pelvic Tilt and Lumbar Lordosis
… tilt causes the lumbar spine to flatten (hypolordosis) which places pressure on the anterior structures of the spine, including the intervertebral disc. This increased pressure may predispose individuals to disc degeneration and associated pain. For this reason, hamstring stretching is often …

Determination of the Functional Relationship Between Lumbar Lordosis and Pelvic Tilt
… examine the influence of altered sagittal lumbar lordosis on sagittal pelvis kinematics during activities of daily living including gait, sit-to-stand, and standto-sit. We hypothesized that a subject would compensate an altered lumbar lordosis by manipulating their pelvic tilt and torso alignment …

Opiate Regulation of Lordosis: Neurochemical Evaluation of the Role of Opiate-Serotonergic Interactions
… However, the role of opiates in the control of lordosis, hormone-dependent female sexual behavior, is less clear. While opiate agonists inhibit lordosis, antagonists do not consistently facilitate behavior. The purpose of the present experiments was to further investigate opiate regulation of …

Kinematic and Kinetic Effects of Alterations in Lumbar Lordosis in People with Tight Hamstrings
… accuracy of sagittal spinal measures of lumbar lordosis, thoracic kyphosis, and sagittal vertical axis, which are calculated using skin markers. Lateral x-rays taken by the EOS bi-planar scanner were used to measure both clinical and marker measures. Sagittal spinal measures were also output by …

Estrogen and 5-HT(1A) receptor function
… tetralin (8-OH-DPAT), inhibited lordosis behavior. However, when rats were given a second estradiol benzoate injection (seven days later) followed by progesterone, the ability of 8-OH-DPAT to inhibit lordosis behavior was reduced. The reduction in the ability of 8-OH-DPAT to …

Investigating the mechanical relationship between the feet and low-back
… the pelvis and subsequently the degree of lumbar lordosis. Since lumbar lordosis has been suggested as a cause of low-back pain, it is speculated that foot orthoses could be used to treat and prevent pain to the low-back by reducing the forward curvature of the spine. This mechanical link between …

Influence of the Pattern of Hormone Administration on Behavioral and Biochemical Responses to Estrogens
… from 3-48 hours apart, and continued to display lordosis as late as 36 hours after the second estrogen exposure. The increased sensitivity to the pulsatile administration of estradiol may be a general characteristic of estrogen-stimulated responses. Neural progestin receptor levels were increased …

Validation and Use of an Induced-Pain Paradigm to Investigate Risk Factors for Low Back Pain Development during Prolonged Standing
… paradigm. In chapter 3, we examined lumbar lordosis in PDs and NPDs. We found that (1) PDs displayed more lumbar lordosis than NPDs and (2) the amount of lumbar lordosis was related to LBP symptom intensity in PDs. In chapter 4 we examined timing of lumbopelvic motion during the active hip …

Comparison of Thoracic and Lumbar Spine Angles and Transient Between Standing and Supine Neutral Axial Twisted Positions
… development, attention should be paid to lumbar lordosis and axial twist in supine neutral and lumbar lateral bend in supine axial twist.

The Role of Breast Size During Prolonged Standing: An Evaluation of Biomechanical, Pain Development, and Psychosocial Factors
… have been found to have greater kyphosis and lordosis angles than women with smaller breasts. The purpose of this study was to investigate whether breast size is related to muscle activation, posture and pain development over a 2-hour prolonged standing exposure and psychosocial metrics. …

Possible role of the ventromedial hypothalamus in estrus termination following vaginocervical stimulation of the rat
… of TTX to the VMH delayed the decrease of lordosis responsiveness typical of estrus termination but no interaction between drug and stimulation treatments was established.

The Effects of Amphetamine Exposure on Neurodevelopment and Behavior in Early Life Stages of Danio Rerio
… that included tail underdevelopment, lordosis, and significantly shorter body lengths. Underlying interneural deficits are further supported with fluorescent antibody staining in the spinal cord, where inhibitory expression was significantly higher in the high amphetamine dose compared …

Interrelationships between spinal and pelvic angles and hip muscle indices and their implications for workspace design
… stress, potential problems of increased lumbar lordosis and their cost-effective alleviation through workspace design. The provision of a footrest, for example, was found to have significant effects on lumbar and pelvic angles in standing as well as in sitting. Further research into standing …

Η φυσιολογική ανάπτυξη της θωρακικής και οσφυϊκής μοίρας της σπονδυλικής στήλης
… curvatures and angles of the spine. Kyphosis and lordosis were measured using Cobb's method and again using a new index which takes into consideration a more accurate geometry of the curves. Separate tables have been completed for every individual anthropometric parameter evaluated by sex and age. …

Ultrasonic Communication and the Hormonal Modulation of Aggressive Behavior in the Female Hamster
… has been initiated, ultrasounds by males prolong lordosis, thus helping to structure the interaction so as to facilitate successful reproduction. As in the case of the aggressive responses described above, hamster ultrasounds seem well suited to a behavioral system that strives to coordinate …

Sexual Behavior in Normal and Prenatally Androgenized Female Hamsters
