BACKGROUND Slowed gait is an important health indicator in older adults but a single identifiable cause is often lacking. We assessed whether a summary index measuring impairments across multiple physiologic systems was associated with slowed gait in older individuals. METHODS Data from the Cardiovascular Health Study (n = 3,010) were used to assess associations between baseline physiologic i...

The characteristics of vertical ground reaction force (VGRF) gait patterns in children with autism spectrum disorders (ASD) are poorly understood. The purpose of this study was to identify VGRF gait features that discriminate between children with ASD and the peer control group. The VGRF data were obtained from 30 children with ASD and 30 normal healthy children aged 4 to 12 years. A three-dime...

This paper explores gait recognition for various walking speeds. Normal-constant speed is one of the assumptions being made in many current gait recognition techniques. However, some techniques do not scale well when certain gait conditions such as walking speed varies. We demonstrate the characteristics of time-distance gait parameters, stride length and cadence, with respect to walking speed ...

OBJECTIVES To evaluate the usual gait speed of asymptomatic adult and elderly Brazilians with a 10-meter walk test and to compare the results with foreign reference values. METHODS Seventy-nine asymptomatic volunteers ≥40 years old of both genders were assessed. After anamnesis, anthropometry and the application of a habitual physical activity questionnaire, the volunteers were submitted to a...

The aim of this research was to establish a kinematic pattern of adult gait for motion analysis system BTS Smart-E used in the research conducted in the Laboratory of Biomechanical Analysis, University School of Physical Education, Wrocław. This research presents the results of gait patterns for a group of 17 adult males for three speed levels: high (1), preferred (2), and low (3). Subject's se...

BACKGROUND Reduced gait speed is associated with falls, late-life disability, hospitalization/institutionalization and cardiovascular morbidity and mortality. Aging is also accompanied by a widening of pulse pressure (PP) that contributes to ventricular-vascular uncoupling. The purpose of this study was to test the hypothesis that PP is associated with long-distance gait speed in community-dwel...

Objectives: To evaluate the usual gait speed of asymptomatic adult and elderly Brazilians with a 10-meter walk test and to compare the results with foreign reference values. Methods: Seventy-nine asymptomatic volunteers ≥40 years old of both genders were assessed. After anamnesis, anthropometry and the application of a habitual physical activity questionnaire, the volunteers were submitted to a...

INTRODUCTION Gait speed provides an integrated index of physical performance; changes in gait speed could reflect deterioration in the underlying medical disorder or a response to medical/surgical interventions. Slower gait speeds reflect the overall level of impairment, especially in patients with chronic lung disease. METHODS We retrospectively reviewed the medical files of 119 patients who...

Purpose: Considering the influence of horizontal velocity on many biomechanical characteristics of walking, the purpose of this study was to investigate how inter-lower-limbs local and global asymmetry is influenced by changes in walking speed from slow to fast. Methods: Ground reaction force data and trajectory of attached markers of bilateral lower limbs of 15 right leg-dominant able-bodied ...

BACKGROUND Reduced gait speed is common following traumatic brain injury (TBI). Several studies have found that people with TBI display increased lateral movement in their center of mass while walking. It has been hypothesized that reduced gait speed following TBI is a consequence of increased caution and postural instability, but reduced ankle power generation at push-off may also play a contr...
