[Purpose] The purpose of this study was to compare the gait parameters of age-matched people with a normal gait (≥ 65 years), age-matched people with knee pain, and age-matched people with walker dependent gait at a self-selected gait speed. [Methods] Subjects walked on even ground in bare feet and were allowed a natural arm swing on a 6-m walkway. Walker-dependent participants walked on a walk...

Walking speed is widely used to study human health status. Wearable inertial measurement units (IMU) are promising tools for the ambulatory measurement of walking speed. Among wearable inertial sensors, the ones worn on the wrist, such as a watch or band, have relatively higher potential to be easily incorporated into daily lifestyle. Using the arm swing motion in walking, this paper proposes a...

QUESTION Which measures of activity limitation on admission to rehabilitation after stroke best predict walking speed at discharge? DESIGN Prospective observational study. PARTICIPANTS 120 people with stroke undergoing inpatient rehabilitation. OUTCOME MEASURES Predictors were admission walking speed, Timed Up and Go, Motor Assessment Scale, Modified Elderly Mobility Scale, and Functional...

BACKGROUND Functional decline is a primary risk factor for institutionalization and mortality among older adults. Although community-based fall risk reduction programs have been widely disseminated, little is known about their impact on gait speed, a key indicator of functional performance. Changes in functional performance between baseline and post-intervention were examined by means of timed ...

were derived by Edward Lorenz in 1963 as an over-simplified model of convection rolls within the atmosphere [1]. These coupled differential equations appear quite harmless; only two terms appear that cause non-linearity. Lorenz found, however, that the behavior of the system changed drastically over a wide range of parameters. For certain parameter values, Lorenz discovered that the system exhi...
