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...

The objective of this study was to measure gait abnormalities in elderly fallers with the LocometrixTM gait-analysis system. This accelerometric device provided the following gait variables: walking speed and stride frequency, length, symmetry, and regularity. The variables were analyzed over a 20-s period of stable walking on a flat track of 40 m. Participants were 20 elderly patients hospital...

Gait has been shown to be an efficient biometric feature for human identification at a distance from a camera. However, performance of gait recognition can be affected by various problems. One of the serious problems is view change which can be caused by change of walking direction and/or change of camera viewpoint. This leads to a consequent difficulty of across-view gait recognition where pro...

This thesis develops methods of control that allow a multi-legged robot to vary its stepping pattern, the gait of a robot, during locomotion. By constructing feedback control around the gaits a robot may use, we produce behaviors allowing a robot to switch amongst or return to certain gaits while performing feedback control during locomotion. Gait regulation is one specific aspect of gait-based...

objectives: foot and ankle problems are common complications in rheumatoid arthritis disease. gait pattern such as normal foot and ankle rocker is impaired in patients with rheumatoid arthritis. rocker sole as an external shoe modification is commonly prescribed in this pathology. the aim of this study was to investigate the effect of rocker shoe on vertical ground reaction force parameters dur...

conclusions zebris movement analysis system is a highly reliable instrument for the measurement of gait parameters at different speeds in healthy athletes and those after acl reconstruction surgery. this implies its use in the assessment and treatment process of gait deficits in such a clinically important population. background reconstruction surgery is one of the treatment methods after an an...

BACKGROUND AND PURPOSE Associations between the site of brain injury and poststroke gait impairment are poorly understood. Temporal gait asymmetry after stroke is a salient index of gait dysfunction that has important functional consequences. The current study investigated whether subtraction lesion analysis could distinguish brain regions associated with persisting temporal gait asymmetry in c...

OBJECTIVES To distinguish the gait patterns of young subjects from those of elderly men using three-dimensional (3D) gait data, to determine if elderly subjects displayed other than a typical gait pattern, and to identify which parameters best describe them. DESIGN Nonrandomized study in which video and force plate data were collected at the subject's own free walking speed and used in a 3D i...

Biomechanical gait parameters--ground reaction forces (GRFs) and plantar pressures--during load carriage of young adults were compared at a low gait cadence and a high gait cadence. Differences between load carriage and normal walking during both gait cadences were also assessed. A force plate and an in-shoe plantar pressure system were used to assess 60 adults while they were walking either no...

INTRODUCTION Accelerometers are becoming an increasingly important tool in the study of human movement. Their ease and affordability, combined with the potential to collect large amounts of continuous data outside the laboratory setting makes them excellent tools for gait analysis. Research has demonstrated the effectiveness of a single tri-axial accelerometer in measuring mean spatiotemporal p...
