Single-well reactive tracer tests, such as the push-pull test are useful tools for characterising in-situ bioattenuation processes in contaminated aquifers. However, the analytical models that are used to interpret push-pull data may be over-simplified, and potentially overlook important processes responsible for the frequent discrepancy between predicted and observed results obtained from push...

BACKGROUND The aim of this study was to examine the impact of intravenous methylprednisolone therapy (IVMP) on the recovery of walking ability in patients experiencing multiple sclerosis (MS) relapses, to compare the responsiveness of walking-based measures, and to estimate the impact of different walking-based measures responsiveness on clinical trials. MATERIAL/METHODS The study included 49...

Background: During locomotion, a gait is pattern of limb movement. The numerous ways in which human can move, either naturally or as result specific training, are referred to gaits. A person's their walking pattern. Walking requires muscle coordination and balance push the body forward rhythm known stride. An irregular could be caused by number factors.Degenerative disease (such arthritis), str...

In this paper we propose system architecture and implementation methodology of walking assistant robot for the elderly. We use shared control system based on sensor feedback. For operation user push or pull handle, than robot sense applied force. It decides velocity and direction of the robot. If obstacles are detected, robot avoids obstacles and plans new path for collision free. It can provid...

Walking speed, stance duration and ground reaction forces were studied with the use of a stable force platform (Kistler) in 24 male transtibial amputees and 12 healthy subjects matched for sex and age. The aim of the study was to compare the gait performance of two groups with unilateral trans-tibial amputations for either vascular disease or trauma and also to compare the results of the two gr...

This study aims at giving an insight into the causative forces of walking in toddlers. Therefore, joint angle, moment and power profiles of 10 toddlers with less than 6 months of walking experience are compared to the stereotype adult patterns. In general, joint moments are small, which can be explained both by the small size of toddlers and differences in walking strategy. Also mass specific p...

Physical rehabilitation after spinal cord injury has been based on the premise that the nervous system is hard-wired and irreparable. Upon this assumption, clinicians have compensated for irremediable sensorimotor deficits using braces, assistive devices, and wheelchairs to achieve upright and seated mobility. Evidence from basic science, however, demonstrates that the central nervous system af...

For humanoid robots to replace humans in dangerous environments, they require a robust fall prevention system that can detect falls, prevent major damage and recover back up to continue on with the task. This paper introduces a system that is capable of fall detection, mitigation and recovery in a robot equipped with walking sticks. Walking sticks allow the humanoid robot to extend its support ...

INTRODUCTION Critical illness myopathy (CIM) and polyneuropathy (CIP) are common complications of critical illness that frequently occur together. Both cause so called intensive care unit (ICU)-acquired muscle weakness. This weakness of limb muscles increases morbidity and delay rehabilitation and recovery of walking ability. Although full recovery has been reported people with severe weakness ...

This study investigated the required coefficient of friction (RCOF) and the tangent of center of mass (COM)-center of pressure (COP) angle in the mediolateral (ML) and anteroposterior (AP) directions during turning at different walking speeds. Sixteen healthy young adults (8 males and 8 females) participated in this study. The participants were instructed to conduct trials of straight walking a...
