Healthy young adults typically exhibit a progressive ‘top-down’ reorientation of body segments (i.e., head, trunk, then pelvis) during turning. This behaviour is less evident in older at risk falling, who often reduce angular displacement between turns. The potential functional and psychological contributors to this so-called ‘en-bloc’ turning strategy are not yet understood. Are there associat...

Many fatal accidents due to falling from height have happen at construction sites in Japan. The purpose of this study is about to seek new prevention methods of fatal accidents due to falling. For the first step, this study was carried out to find out "cause of death" in labor accidents by using past statistics data and was analyzed it. For the second, Butt dropping tests were carried out to me...

This investigation used a standing dummy on slippery and non-slippery surfaces with accelerated movements of a floor to simulate falling backward events. The results revealed the duration of falling, head impact velocity, etc., which are valuable for guiding the development of personal protective equipment, such as wearable airbags. The mechanism, by which a dummy falls backwards due to abrupt ...

High-energy trauma to the shoulder is associated with multiple injuries and is often difficult to evaluate. One of these complex traumas is the displacement of the humeral head into the thoracic cavity. This study aimed to report a patient who presented after falling three floors. Initially, the patient underwent chest drainage and thoracoscopy to remove the displaced humeral head and, subseque...
