Previous studies evaluated various risk factors for knee OA; however, no study has examined the association between spinal factors, such as total spinal alignment and spinal range of motion (ROM), with knee OA. The purpose of this study was to examine the influence of spinal factors including total spinal alignment and spinal ROM on knee OA in community-living elderly subjects. A total of 170 s...

A two fluid model (TFM) was used to study gas-solid heat transfer in a riser with different inclination angles. A two dimensional pipe with 5.8 cm internal diameter and 5 meter length was chosen.  Effect of bed angle and solid particles feed rate were studied on the heat transfer behavior of gas and solid particles. Obtained results from simulation are compared with the experimental data in the...

In an inertial sensor-based pedestrian navigation system, the position is estimated by double integrating external acceleration. A new algorithm is proposed to reduce z axis position (height) error. When a foot is on the ground, a foot angle is estimated using accelerometer output. Using a foot angle, the inclination angle of a road is estimated. Using this road inclination angle, height differ...

The angle of inclination of the acetabular component in total hip replacement is a recognised contributing factor in dislocation and early wear. During non-navigated surgery, insertion of the acetabular component has traditionally been performed at an angle of 45 degrees relative to the sagittal plane as judged by the surgeon's eye, the operative inclination. Typically, the method used to asses...

Using radiographs and diagrams, this article reviews the most commonly used axes and angles of the foot, including: longitudinal axis of the rearfoot, collum tali axis, talocalcaneal angle, cuboid abduction angle, longitudinal axis of the lesser tarsus, lesser tarsus angle, talonavicular angle, longitudinal axis of the metatarsus, forefoot adductus angle, metatarsus adductus angle, first interm...

BACKGROUND One of the reasons women with macromastia chose to undergo a breast reduction is to relieve their complaints of back, neck, and shoulder pain. We hypothesized that changes in posture after surgery may be the reason for the pain relief and that patient posture may correlate with symptomatic macromastia and may serve as an objective measure for complaints. The purpose of our study was ...

This study determined effect of automobile seat backrest inclination on lattisimus dorsi muscle electromyographic (EMG) activity. Myoelectric activity was determined at two seat backrest angles (90 degrees and 100 degrees inclinations).  Twenty-one (21) participants were engaged in the study. Electromygraphic activity at 90 degrees inclination had slope value of -0.065 mV/minute while ...

The aim of this study was to identify anatomic risk factors for scapholunate dissociation. On a PA view of the wrist, in zero position, the scaphoid and lunate diameter and height, lunate tilting angle, lunate uncovering index, lunate fossa inclination, radial inclination and ulnar variance were measured; on a lateral view the scapholunate angle and palmar tilting angle were measured. In a cont...
