Gait kinematics have been shown to vary with speed and visual-target fixation distance, but their combined effects on toe trajectory during treadmill walking are not known. The purpose of this investigation was to determine the role of walking speed and target distance on vertical toe trajectory during treadmill walking. Subjects walked on a treadmill at five speeds while performing a dynamic v...

background: medical shoes are a solution for the construction and performance related to foot problems. people with healthy feet do not require medical shoes. shoes have different designs and heights and are probably produced with different materials depending on the nature of the required correction. ordering medical shoes, like medicine, is personal for each individual. however, today many co...

The black soil of Northeast China has a strong adhesion ability because its unique physical properties, and the often adheres to surface grouser shoes tracked vehicles during operation. performance depends largely on structure parameters shoes. height, thickness, splayed angle were selected as parameters. force adhesive mass indicators performance. Therefore, mathematical model between response...

Coming on the heels of the publication of Tobacco Control’s Twentieth Anniversary issue (vol. 21, issue 2) comes another landmark: David Simpson is stepping down from his longtime position as editor for the journal’s News Analysis section, which he has held since shortly after the journal’s founding in 1992. Mr Simpson’s contributions to tobacco control are legion. Many across the globe, includ...

Wearing high heels (HH) places the calf muscle-tendon unit (MTU) in a shortened position. As muscles and tendons are highly malleable tissues, chronic use of HH might induce structural and functional changes in the calf MTU. To test this hypothesis, 11 women regularly wearing HH and a control group of 9 women were recruited. Gastrocnemius medialis (GM) fascicle length, pennation angle and physi...

The objective of this study was to evaluate how weight classification relates to meeting task constraints. Using a cross-sectional design, three-dimensional motion data were collected while children crossed obstacles of various heights. Twelve normal-weight (≥5th and <85th percentile on growth charts) and 12 overweight or obese (≥85th percentile on growth charts) 4- to 13-yr-olds participated. ...

• Micro-Doppler radar is a novel way to evaluate human motion. The signature projection algorithm able predictably detect subtle changes in accurate detection of motions. Development accessible cost-effective technology objectively, reliably, and accurately predict musculoskeletal injury risk could aid the effort prevent chronic pain disability. Recent work on micro-Doppler suggests it merits i...
