background: musculoskeletal disorders (msds) are one of the most common causes of occupational injuries that appear in the lower back, neck and upper and lower extremities mainly. this study was conducted to assess the risk of msds and determine of its associated factors in workers of a dairy products company. methods: in this cross-sectional study, 100 male employees (21-41yrs) using census sa...

Spectral analysis of continuously measured joint angles using an electrogoniometer was considered as a potentially efficient method for quantifying exposure to physical stress in repetitive manual work. The method was previously demonstrated in the laboratory but has not yet been tested extensively in the field. Spectral analysis was compared against observational analysis, consisting of time-a...

background: proper sleep is essential for the development of premature infants. infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. to compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. this study is a randomized clinical trial which was conducted in neonatal ...

In this report I describe the design and implementation of an fpga-based architecture for video processing and specifically posture analysis. The final architecture performs posture analysis at a rate of 167 frames per second (projected) using frame size of 320×240 pixels, or 41 frames per second for dvd quality (720× 576 pixels) frames. This represents a 21-fold speedup over a software version...

The main goal of the study was to determine the types of body posture of boys (n = 273), 10 to 13 years of age, by means of the body posture assessment method based on the software Posture Image Analyzer. The results should enable better understanding of postural issues, as well as timely and more precise selection of kinesitherapeutic procedures. Values of 5 front view and 4 sagittal view indi...

system [6] is defined for each finger. Recently, the model-based hand posture analysis researches have become increasingly popular for many applications, such as hand gesture recognition, intelligent human-machine interface, virtual reality, and computer animation. However, the main problems that make the conventional marker-based hand posture analysis system inapplicable are inefficient calcul...

background: rounded shoulder posture is a common abnormal posture in upper quarter. kinesiotape is a new intervention that recently used in rehabilitation. there are no studies have examined the effect of kinesiotape on rounded shoulder posture. therefore the purpose of this study was to determine the effect of scapular kinesiotaping and pectoralis minor stretching exercise on forward shoulder ...

Importance of human-computer interaction (HCI) systems is increasing since they revolutionized the way people interact with computers. Gesture and posture analysis, especially hand gesture and posture recognition, is one of the more recent areas in the HCI with ever widening field of applications. In this paper we propose an algorithm for hand posture recognition that is based on skin detection...
