In this paper, we propose a method to estimate the 3D human posture from monocular image without using the markers. A 3D human body is expressed by a multi-joint model, and a set of the joint angles describes a posture. The proposed method estimates the posture using Histograms of Oriented Gradients (HOG) feature vectors that can express the shape of the object in the input image obtained from ...

The objective of this study was to explore whether differences in standing and sitting postures of youth with idiopathic scoliosis could be detected from quantitative analysis of digital photographs. Standing and sitting postures of 50 participants aged 10-20-years-old with idiopathic scoliosis (Cobb angle: 15° to 60°) were assessed from digital photographs using a posture evaluation software p...

background: musculoskeletal symptoms are the main cause of loss of working time, and increase in labor costs. poor posture is the most important risk factor for work-related musculoskeletal symptoms. this study aimed at evaluating the role of ergonomic risk factors in different surgical (open surgery, laparoscopy, and microsurgery) in the frequency or resonance frequency of musculoskeletal symp...

introduction: spinal malalignment is a common problem in the present societies and forward head posture is one of the most common dysfunction in cervical region. the purpose of the present study is to evaluate effect of stabilization exercises in improving of forward head posture. materials and methods: twenty six female students with forward head posture in age range of 20-27 years old partici...

background: standing workstation can be a strategic approach for many electronics manufacturers to achieve work optimization. however, the well-being of the workers has become a great issue for both workers and employers. the main objective of this research was to study the effects of standing working posture on the workers and their impact to workers’ health and productivity and then to re-des...

Posture can be defined as the form of the body when sitting, walking, or standing. There would be no problem if muscles interact in harmony with musculoskeletal system or nervous system. Posture analysis is crucial for clinical assessments in physical medicine and rehabilitation. However, studies into this issue are limited. In this study, the relationship between static standing balance and an...

[Purpose] Measurement of posture is important for those with a clinical diagnosis as well as researchers aiming to understand the impact of faulty postures on the development of musculoskeletal disorders. A reliable, cost-effective and low tech posture measure may be beneficial for research and clinical applications. The purpose of this study was to determine rater reliability and construct val...

The inherent difficulty of measuring forces on the hand in ergonomic workplace assessments has led to the need for equations to predict grip force. A family of equations was developed, and validated, for the prediction of grip force using forearm electromyography (six finger and wrist muscles) as well as posture of the wrist (flexed, neutral and extended) and forearm (pronated, neutral, supinat...
