The effects of walking speed and age on the peak external moments generated about the joints of the trailing limb during stance just prior to stepping over an obstacle and on the kinematics of the trailing limb when crossing the obstacle were investigated in 10 healthy young adults (YA) and 10 healthy older adults (OA). The peak hip and knee adduction moments in OA were 21-43% greater than thos...

The under-actuated foot rotation that the heel of the stance leg lifts off the ground and the body rotates around the stance toe is an important feature in human walking. However, it is absent in the realized walking gait for the majority of biped robots because of the difficulty and complexity in the control it brings about. In this paper, a hybrid control approach aiming to integrate the main...

The nervous system can adapt to external forces that perturb locomotion by correcting errors in limb movements. It is believed that supraspinal structures mediate these adaptations, whereas the spinal cord contributes only reflexive responses to perturbations. We examined whether the lumbar spinal cord in postnatal day 5 neonatal spinally transected (ST) rats corrected errors in hindlimb coordi...

BACKGROUND AND PURPOSE Although stroke survivors often display abnormal joint torque patterns, studies of torque-coupling in the lower limb are lacking, despite their potential impact on gait abnormalities. METHODS Twenty-two chronic ambulating stroke subjects and 11 age-matched control subjects produced isometric hip torques in the frontal and sagittal planes with the hemiparetic leg (or ran...

we report engineering experiences from the critical task of relief well installation under high artesian flow conditions at the downstream toe of the karkheh earth dam, iran. due to the establishment of excessive uplift pressure at the downstream toe of the karkheh dam, installation of a series of new relief wells was considered to permanently relieve part of these pressures. the mentioned upli...

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...

Background: Melorheostosis has been discussed infrequently in the nuclear medicine literature. A 25-year-old female patient presented with a one-year history of b:union: pain, sclerotic change and skin pigmentation on the left big toe interphalangeal joint. Ulceration, poor healing and hyperkeratoses of the wound were noted post debridement. The plain film of the left foot incidentally showed m...

[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...

Purpose The aim of our study is to selectively visualize toe arteries without contrast media and exhibit correlations with age and gender. Non-contrast ECG-gated 3D half-Fourier FSE MR angiography with time-spatial labeling inversion pulses (time-SLIP) was investigated for efficacy in depicting the toe arteries using swap phase encode extended data (SPEED) acquisition. Materials and Methods All...

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...
