The objective of this study was to investigate spatiotemporal characteristics with gait variability in patients with freezing of gait (FOG) after hypoxic-ischemic brain injury (HIBI).Eleven patients showing FOG after HIBI and 15 normal controls were consecutively enrolled. We performed gait analysis using a computerized gait system (VICON MX-T10 Motion Analysis System) and compared spatiotempor...

The purpose of this study was to describe and statistically analyze 3- and 5-year-old children's gait at slow, free, and fast speeds in terms of stride length, step length (adjusted for leg length), stride width, included angle of feet, and cadence. The study also correlated gait factors and motor development. Gait patterns were recorded with a clinical, footprint method. In general, stride len...

With aging, individuals' gaits become slower and their steps shorter; both are thought to improve stability against balance threats. Recent studies have shown that shorter step lengths, which bring the center of mass (COM) closer to the leading foot, improve stability against slip-related falls. However, a slower gait, hence lower COM velocity, does the opposite. Due to the inherent coupling of...

BACKGROUND Gait acquisition is supported by changes in the neuromusculoskeletal system of the child. Changes in the dimensions of the body structures resulting from the growth of the child partly explain gait improvement in the first year of life. OBJECTIVES To evaluate whether changes in body mass and leg length modulate the effect of independent gait practice (experience) on gait speed and ...

OBJECTIVE To investigate whether gait dysfunction is a predictor of severe spatial learning and memory impairment in aged mice. METHODS A total of 100 12-month-old male mice that had no obvious abnormal motor ability and whose Morris water maze performances were not significantly different from those of two-month-old male mice were selected for the study. The selected aged mice were then divi...

Objectives: Fear of falling (FOF) is a common complication after stroke affecting gait and balance performance in individuals with a history of stroke. The current study aimed at determining the influence of the level of FOF on gait and balance performance after chronic stroke. Methods: A total of 76 persons with chronic stroke (including 41 women), who had no cognitive impairment and could wa...

This paper employs nonlinear disturbance observer (NDO) for robust trajectory-free Nonlinear Model Predictive Control (NMPC) of biped robots. The NDO is used to reject the additive disturbances caused by parameter uncertainties, unmodeled dynamics, joints friction, and external slow-varying forces acting on the biped robots. In contrary to the slow-varying disturbances, handling sudden pushing ...

OBJECTIVE To determine the factors associated with gait parameters in female patients with rheumatoid arthritis (RA). METHODS The gait analysis was performed in a large cohort of RA patients, and three basic gait parameters (step length, cadence and gait speed) were calculated. Clinical and laboratory data were also collected. Factors associated with gait parameters were analyzed using multiv...
