Traumatic injuries can be used as general indicators of activity patterns in past populations. This study tests the hypothesis that contemporaneous (10th-12th century) rural and urban populations in medieval Poland will have a significantly different prevalence of non-violent fractures. Traumatic injuries to the post-cranial skeleton were recorded for 180 adults from rural Giecz and for 96 adul...

OBJECTIVES Non-medical hospital staff members are in frequent contact with patients and therefore are required to perform a wide variety of repetitive and high-frequency activities. The objective of this study was to assess the relationships between upper extremity activity and carpal tunnel syndrome (CTS) among non-medical hospital staff members. MATERIAL AND METHODS Carpal tunnel syndrome i...

Human Activity Recognition (HAR) has been widely addressed by deep learning techniques. However, most prior research applied a general unique approach (signal processing and learning) to deal with different human activities including postures gestures. These types of activity typically have highly diverse motion characteristics, which could be captured wearable sensors placed on the user’s body...

OBJECTIVE To chronicle the conservative treatment and management of two work-related cases of lateral elbow pain diagnosed as lateral epicondylopathy. CLINICAL FEATURES PATIENT 1: A 48-year old female presented with gradual onset of right lateral elbow pain over the course of six weeks related to work activities of repetitive flexion/extension movements of the wrist and finger keying. PATIEN...

The human work possess a history and, in this dimension, the man is submitted to the conditions that confer it physical and psychological consequences. The activity of work in the present time imposes adverse labor conditions. The ergonomics is a science that it aims at to study the real activity of the work with sights its transformation. This study it was carried through in a sector of proces...

Highway construction projects are one of the most important construction projects in the world. Therefore predicting the time of these kinds of projects is important. Basically highway projects are including few activities which are repeating along the horizontal direction. One of the best methods for scheduling these types of projects is linear scheduling method. The repetitive nature of the h...

Obstructive sleep apnea (OSA) is more common in men than in women for reasons that are unclear. The stability of the respiratory controller has been proposed to be important in OSA pathogenesis and may be involved in the gender difference in prevalence. Repetitive hypoxia elicits a progressive rise in ventilation in animals [long-term facilitation (LTF)]. There is uncertainty whether LTF occurs...

Many object motions in nature are cyclic and this provides a strong cue for object and activity recognition. Recently, there has been a lot of research effort into detecting and recognising cyclic or near-periodic activities such as a person walking or waving a hand. The main characteristic these approaches share is that they don’t require an object or motion specific model. Periodic and cyclic...

Work-related musculoskeletal disorders (WMSD) are caused by the overuse of muscles in the workplace. Performing repetitive tasks is a primary risk factor for the development of WMSD. Many workers in highly repetitive jobs exhibit muscle pain and decline in handgrip strength, yet the mechanisms underlying these dysfunctions are poorly understood. In our study, rats performed voluntary repetitive...
