Electronic mobility aid, transforms visual information to another sensory modality, has proved be useful for visually impaired people commute confidently and independently. With recent developments in technology, more can provided that assist the user better way avoid obstacles. The paper is focused on portable aid prototype based stereo imaging help collision with algorithm segmentation of dis...

OBJECTIVE To validate an incremental field walking test, the shuttle walking test, as a means of assessing pacing modes and to aid programming of rate responsive pacemakers. DESIGN Three separate groups of patients were recruited. Reproducibility (n = 10) of the shuttle walking test was assessed by performing three consecutive tests. Comparison of the shuttle walking test with a 10 min walk w...

Gait phase-based control is a trending research topic for walking-aid robots, especially robotic lower-limb prostheses. phase estimation challenge gait control. Previous researches used the integration or differential of human's thigh angle to estimate phase, but accumulative measurement errors and noises can affect results. In this letter, more robust method proposed using unified form piecewi...

OBJECTIVES To evaluate fall risk in stroke patients based on single- and dual-task gait analyses, and to investigate the difference between 2 cognitive tasks in the dual-task paradigm. DESIGN Prospective cohort study. SETTING Rehabilitation hospitals. PARTICIPANTS Subacute stroke patients (N=32), able to walk without physical/manual help with or without walking aids, while performing a ve...

OBJECTIVE To compare daily stride rate activity, daily exercise intensity, and heart rate intensity of stride rate in children with cerebral palsy with that of typically developing children. METHODS Forty-three children with cerebral palsy, walking without (Gross Motor Function Classification System (GMFCS) I and II) or with (GMFCS III) an aid and 27 typically developing children (age range 7...

People with both visual and mobility impairments have great difficulty using conventional mobility aids for the blind. As a consequence they have little opportunity to take exercise without assistance from a carer. The combination of visual and mobility impairments occurs most often among the elderly. In this paper we examine the issues related to mobility for the blind and pay particular atten...

After a long time as a junior partner in robotics, walking has seen an explosion in interest and achievements in the last 15 years as computational power unimaginable until recently has been brought to bear on its problems. At the same time we have seen advances in other related fields: non-linear dynamics has helped us understand and model the robotic systems that we are studying; zoology has ...
