PURPOSE Gait speed is an important objective values associated with several health-related outcomes including functional mobility in aging people. However, walking test methodologies and descriptions are not standardized considering specific aims of research. This study examine the reliability and validity of gait speed measured at various distances and paces in elderly Koreans. METHODS Fifty...

PURPOSE The purpose of this study was to examine the effects of a total body strength training program on oxygen uptake (VO2), heart rate (HR), systolic blood pressure (SBP), and rate pressure product (RPP) during a submaximal walk and a weight-loaded walking test in healthy women 60-77 years old. METHODS The submaximal walk (2 mph and 3.5% grade) took place during stage 3 of a graded exercis...

BACKGROUND The optimal way of assessing the impact of pulmonary rehabilitation on functional status in chronic obstructive pulmonary disease (COPD) is currently unknown. The minimal clinically important difference for the constant work rate cycling exercise test also needs to be investigated to facilitate its interpretation. A study was undertaken to evaluate the changes in the 6-min walking te...

We propose an analog CMOS circuit for developing a biologically-inspired locomotion controller for a quadruped walking robot. The proposed circuit is based on the biological neural network, called the central pattern generator (CPG), that can generate rhythmic movements for locomotion of animals, such as walking, running, swimming, and flying. We constructed a CPG model from the WilsonCowan neu...

OBJECTIVES To investigate: (i) the intra-rater, inter-rater and test-retest reliabilities of completion times and step counts on the Standardized Walking Obstacle Course test (SWOC); (ii) correlations between SWOC scores and stroke-specific impairments; (iii) the cut-off SWOC completion times and step counts for distinguishing differences in obstacle negotiation ability in people with chronic s...

BACKGROUND AND PURPOSE Walking ability poststroke is commonly assessed using gait speed categories developed by Perry et al. The purpose of this study was to reexamine factors that predict home and community ambulators determined from real-world walking activity data using activity monitors. METHODS Secondary analyses of real-world walking activity from 2 stroke trials. Home (100-2499 steps/d...

OBJECTIVE To determine whether the cognitive function contribution to straight- and curved-path walking differs for older adults. DESIGN Cross-sectional observational study. SETTING Ambulatory clinical research training center. PARTICIPANTS People (N=106) aged 65 to 92 years, able to walk household distances independently with or without an assistive device, and who scored 24 or greater o...

INTRODUCTION Although the health benefits of walking for physical activity have received increasing research attention, barriers specific to walking are not well understood. In this study, questions to measure barriers to walking for physical activity were developed and tested among college students. The factor structure, test-retest and internal consistency reliability, and discriminant and cr...

There has been research interest in using the micro Doppler effect for contactless measurements of human respiration. Most of the research assumes that the test subject remains stationary. The purpose of this paper is to detect a respiration signal from a walking human. This work is at an early stage, and MATLAB model for a walking human with respiration movement was used, instead of recreating...

[Purpose] The purpose of this study was to compare differences in respiratory pressure and pulmonary function and the effectiveness of respiratory feedback training according to walking ability in children with cerebral palsy (CP). [Subjects and Methods] Twenty-three children with spastic CP were enrolled in the final analysis and were divided into an independent walking group (n=12) and non-in...
