in this paper, an approximate method is proposed for determining sway of multistory rc buildings subjected to various types of lateral loads. the calculation of both fundamental period and stability index in rc building requires the sway term at each story level. using approximate method design engineers can estimate sway terms at each story level. the developed analytical expressions are inser...

Abstract Virtual Reality (VR) experienced through head-mounted displays often leads to vection, discomfort and sway in the user. This study investigated effect of motion direction eccentricity on these three phenomena using optic flow patterns displayed Valve Index. Visual stimuli were presented centre, periphery or far moved either depth (back forth) laterally (left right). Overall vection was...

BACKGROUND/AIM To investigate the effects of an 8-week thoracic stabilization exercise program on back pain, spinal alignment, postural sway, and core endurance in university students. MATERIALS AND METHODS University students were randomly allocated into exercise (n: 28) and control (n: 25) groups. The exercise program was carried out 3 days a week for 8 weeks. Postural pain, spinal alignmen...

BACKGROUND Ear Acupuncture (EA) is a form of acupuncture in which needles are applied to the external ear and has been used in multiple painful conditions. Low back pain (LBP) is highly prevalent in active individuals and causes high economic burden to health systems worldwide. LBP affects the person's ability to keep balance, especially in challenging conditions. OBJECTIVE The aim of the stu...

Musculoskeletal injuries are a common occurrence in military service members. It is believed that the load carried by the service member impedes stability and alters back and pelvis kinematics, increasing their susceptibility to musculoskeletal injuries, specifically in the lower extremities. The purpose of this study was to examine the effects of two different loads on postural sway, forward t...

The purpose of this study was to compare the postural sway profiles of 20 boys with and without Developmental Coordination Disorder (DCD) on two conditions of a quiet standing task: eyes open and eyes closed. Anteriorposterior (AP) sway, medio-lateral sway (LAT), area of sway, total path length, and Romberg’s quotient were analyzed. When visual information was available, there was no difference...

HYPOTHESIS We hypothesized that the prevalence of rotator cuff tears would be higher among individuals with poor posture, regardless of the presence of symptoms. METHODS The study initially comprised 525 residents of a mountain village who participated in an annual health check. Participants completed a background questionnaire, and physical examinations were performed to evaluate shoulder fu...
