[Purpose] Smartphone use reportedly changes posture. However, how neck posture is altered in smartphone users with neck pain is unknown. This study examined changes in the posture of young adults with and without mild neck pain (MNP) when using a smartphone. [Subjects] Thirteen control subjects and 14 subjects with MNP who used smartphones were recruited. [Methods] The upper cervical (UC) and l...

We present a method for real-time bare hand tracking that utilizes natural hand synergies to reduce the complexity and improve the plausibility of the hand posture estimation. The hand pose and posture are estimated by fitting a virtual hand model to the 3D point cloud obtained from a Kinect camera using an inverse kinematics approach. We use real human hand movements captured with a Vicon moti...

Background: Movement dysfunction may be expressed in terms of symptoms experienced in non-physiological postures, and head-down crooked kneeling (HDCK) is a posture frequently assumed by Muslims during prayer activities. The purpose of this study was to investigate the cardiovascular responses in the HDCK posture. Methods: Seventy healthy volunteers, comprising 35 males and 35 females, ...

Authors investigated the effects of different jaws relations on body posture in a sample of 95 subjects. All subjects underwent a posturometric and stabilometric analysis using a computerized footboard. Tests were performed in three mandibular positions: centric occlusion, rest position and myocentric position, respectively determined by teeth engagement, joints position, and muscles contractio...

the facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient's natural head position. the purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion.our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class i (n=32), class ii (n=40) and class iii (n=30). nin...

In this paper, we propose to investigate the role of a new descriptor named Kernel Descriptor (KDES), recently introduced in 1 for hand posture recognition. As the hand posture has it own the color characteristic, we will examine kernel descriptor in diffident color channels such as HSV, RGB, Lab to find out the most suitable color space for kernel representation of hand posture. We perform ext...

The aim of this work was to analyse possible influence of passive sacroiliac joint mobilisation on body posture changes in the sagittal plane. Investigations embraced 900 children and young people aged 5–19 with symptoms of functional asymmetry of the pelvis. One evaluated the quality of body posture twice – alternately in habitual standing and during autoelongation in starting examination – an...

This paper describes an emotion recognition system for dogs automatically identifying the emotions anger, fear, happiness, and relaxation. It is based on a previously trained machine learning model, which uses automatic pose estimation to differentiate emotional states of canines. Towards that goal, we have compiled picture library with full body dog pictures featuring 400 images 100 samples ea...
