BACKGROUND Dynamic knee valgus contributes to injuries of the anterior cruciate ligament (ACL). However, it is unclear how the knee rotates during dynamic knee valgus. Knee rotation significantly affects ACL strain. To understand knee rotation during dynamic knee valgus should help the clinician evaluate dynamic alignment. The purpose of this study was to determine how the knee rotates during d...

iran is ranked fourth for saline-sodic soils in asia following china, india and pakistan. therefore, if coupled with waterlogging, drainage would be an inevitable and indispensable activity agriculture in most irrigated parts of iran. drain installation depth is one of the main economic as well as environmental challenges in design and construction of drainage systems. deep pipe drain installat...

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...

This study was performed to test the hypothesis that reducing the horizontal distance between the trailing foot (foot crossing the obstacle last) and obstacle, during stance just prior to stepping over the obstacle, would reduce flexion of the hip, knee, and ankle joints of the trailing limb when the toe is over the obstacle to reduce the vertical toe-obstacle clearance and increase the risk of...

Wide variety of timings and techniques has been used based on the housing, production, availability of requirements etc. This current study was done for a morphologic evaluation of the cow's digit in different trimming times. A dairy herd with 2200 milking cow, free stalls barns, average daily production of 36 liters per cow was selected. Forty cows were assigned to four groups based on hoof tr...

BACKGROUND The Ankle Brachial Index is a useful clinical test for establishing blood supply to the foot. However, there are limitations to this method when conducted on people with diabetes. As an alternative to the Ankle Brachial Index, measuring Toe Systolic Pressures and the Toe Brachial Index have been recommended to assess the arterial blood supply to the foot. This study aimed to determin...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...

In this paper, the role of the human being toe is investigated. The change of the sole pressure distribution using a sole pressure distribution measurement system and that of the toe pressure using a toe pressure measurement system at walk by the existence of a toe are investigated. In order to investigate the change of the whole walking, the affection of a walk posture using a 3D motion captur...

[Purposes] To investigate angular changes in the ankle joint and leg muscle activities during toe-gripping, and to examine the relationship between these changes and toe-gripping strength. [Subjects] Eleven healthy young women were selected. [Methods] We measured the toe-gripping strength, angular changes in the ankle joint, and leg muscle activities of all patients during toe-gripping. [Result...
