Load in the human body can be quantified as force, stress, or strain, depending on the anatomical structure and the measuring technique. Direct measurements of these variables are invasive and only possible in animals or in small-scale in vivo studies in humans. Miniaturization of transducers and electronics may open new possibilities for direct measurements of load in the human body. Studies w...

BACKGROUND A preliminary study using the "gravitational wellness" weightlifting technique demonstrated this to be a unique technique for loading the musculoskeletal system with extremely high loads over short arcs. This leads to rapid weekly strength gains using 30-minute weekly training sessions. This study was designed to further assess the benefit-risk ratio of the gravitational wellness wei...

Playing a musical instrument at an elite level is a highly complex motor skill. The regular daily training loads resulting from practice, rehearsals and performances place great demands on the neuromusculoskeletal systems of the body. As a consequence, performance-related musculoskeletal disorders (PRMDs) are globally recognized as common phenomena amongst professional orchestral musicians. The...

Introduction: Low back pain is the most prevalent orthopedic disorder and the first main cause of poor working functionality in developed as wells as many developing countries. In Absence of noninvasive in vivo measurement approaches, biomechanical models are used to estimate mechanical loads on human joints during physical activities. To estimate joint loads via musculoskelet...

Introduction: Musculoskeletal disorders (MSDs) are most important work-related injuries and debilities in developed and developing industrial countries. In the recent years, the rate of injuries and MSDs in car montage industries compared with other industries was so more. Therefore, the purpose of present study was focused on ergonomic assessment of sina car montage industry employees’ workin...

Background: Obesity is the most modifiable risk factor, and dietary induced weight loss potentially the best nonpharmacologic intervention to prevent or to slow osteoarthritis (OA) disease progression. We are currently conducting a study to test the hypothesis that intensive weight loss will reduce inflammation and joint loads sufficiently to alter disease progression, either with or without ex...

Loads on the plantar fascia could be influenced by running speed and relate to its pathology. This study calculated compared strains under different conditions using a dynamic finite element foot model computational simulations. The was previously validated featuring twenty bones, bulk soft tissue, muscles/ligaments, solid part of fascia. A runner performed trials one preferred (PS), two lower ...
