Background: According to clinical observations, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity, leading to structural and functional deficits in standing and walking. This study aimed at investigating the effect of foot hyperpronation on spine alignment in the standing position.   Methods: Thirty-five healthy males with an age range of 18-30 year...

OBJECTIVES Normal sagittal spine-pelvis-lower extremity alignment is crucial in humans for maintaining an ergonomic upright standing posture, and pathogenesis in any segment leads to poor balance. The present study aimed to investigate how this sagittal alignment can be affected by severe knee osteoarthritis (KOA), and whether associated changes corresponded with symptoms of lower back pain (LB...

STUDY DESIGN Cross-sectional observational study on the relationship between the degrees of disc degeneration and sagittal alignment in asymptomatic healthy individuals. OBJECTIVE This study sought to determine whether the sagittal spine alignment subtype is related to the prevalence of lumbar disc degeneration. SUMMARY AND BACKGROUND DATA Sagittal balance and spinopelvic parameters might b...

Objective. The objective of this study was to investigate the effect of a holistic intraoral appliance (OA) on cervical spine alignment and subjective symptom severity. Design. An observational study on case series with holistic OA therapy. Setting. An outpatient clinic for holistic temporomandibular joint (TMJ) therapy under the supervision of the Pain Center, CHA Biomedical center, CHA Univer...

This study implements an algorithm for the autonomous control of spinal alignment during sleep by the active adjustment of mechanical bed characteristics according to the adopted sleep posture. Bed systems were used that allow active control of the mechanical stiffness in eight comfort zones by means of separately adjustable actuators. Mattress indentation measurements provide the input to dete...

BACKGROUND While appropriate pillow height is crucial to maintaining the quality of sleep and overall health, there are no universal, evidence-based guidelines for pillow design or selection. We aimed to evaluate the effect of pillow height on cranio-cervical pressure and cervical spine alignment. METHODS Ten healthy subjects (five males) aged 26 ± 3.6 years were recruited. The average height...

STUDY DESIGN In vivo biomechanical study using a three-dimensional (3D) musculoskeletal model for elderly individuals with or without pelvic retroversion. PURPOSE To evaluate the effect of pelvic retroversion on the sagittal alignment of the spine, pelvis, and lower limb in elderly females while standing and walking. OVERVIEW OF LITERATURE Patients with hip-spine syndrome have concurrent hi...

Object. The effects of sagittal kyphotic deformities or mechanical stress on the development of cervical spondylotic myelopathy, or the reduction and fusion of kyphotic sagittal alignment have not been consistently documented. The aim in this study was to determine the effects of kyphotic sagittal alignment of the cervical spine in terms of neurological morbidity and outcome after 2 types of su...
