In nowdays digitalized and industrialized society, sitting is the most frequent posture at work, at school and also during the leisure time (surfing on the internet, gaming...). Because of gravity, the erect posture is associated with an increase of the lumbar intra-discal pressure, which has first been evidenced in the in vivo measurements of Nachemson [1-3]. In these studies, the authors depi...

OBJECTIVE This work aimed to assess tibial rotations, meniscal movements, and morphological changes during knee flexion and extension using kinematic magnetic resonance imaging (MRI). METHODS Thirty volunteers with healthy knees were examined using kinematic MRI. The knees were imaged in the transverse plane with flexion and extension angles from 0° to 40° and 40° to 0°, respectively. The tib...

Introduction: There are multiple factors which can affect spinal range of motion such as medical conditions, pelvic asymmetry age, sex, race and geographical distribution etc. Aim: The present study aims to assess the differences between genders for trunk mobility in normal adults. Material & methods: In this cross sectional study, 137 subjects (71 females 66 males) were included 6 months f...

The single leg squat (SLS), forward step down (FSD), and lateral (LSD) are clinically reliable movement screens for identifying motion imbalances. current understanding the kinematic profiles of each task is limited to discrete time points such as peak knee flexion. However, analyses entire would better aid clinicians when selecting appropriate rehabilitation or screen purposes. study used Stat...

OBJECTIVE The purpose of this study was to explore the relationship between the kinematic profiles of flexion of the upper lumbar and lower lumbar (LL) spine and hip and 3 sagittally dominant functional tasks (lifting, stand-to-sit, and sit-to-stand). METHODS Fifty-three participants were recruited for this study. Four sensors were attached to the skin over the S1, L3, T12, and lateral thigh....

OBJECTIVE To assess the correlation of abnormal trunk postures and reposition sense of subjects with forward head neck posture (FHP). METHODS In all, postures of 41 subjects were evaluated and the FHP and trunk posture including shoulder, scapular level, pelvic side, and anterior tilting degrees were analyzed. We used the head repositioning accuracy (HRA) test to evaluate neck position senses...

BACKGROUND Activities that require extreme hip movement can dislocate hip implants in the early post operative phase. One such activity is retrieving an object from the floor. The aim of this study was to assess hip movement using four different techniques to accomplish this task. This assessment would identify the techniques least likely to cause a hip dislocation. METHODS An electromagnetic...
