Although gait-related dual-task interference in aging is well established, the effect of gait and cognitive task difficulty on dual-task interference is poorly understood. The purpose of this study was to examine the effect of gait and cognitive task difficulty on cognitive-motor interference in aging. Fifteen older adults (72.1 years, SD 5.2) and 20 young adults (21.7 years, SD 1.6) performed ...

OBJECTIVES To examine the association between statin use and objectively assessed decline in gait speed in community-dwelling older adults. DESIGN Longitudinal cohort study. SETTING Health, Aging and Body Composition (Health ABC) Study. PARTICIPANTS Two thousand five participants aged 70-79 at baseline with medication and gait speed data at 1998-99, 1999-2000, 2001-02, and 2002-03. MEAS...

In this study, we analyse the electroencephalography (EEG) signal associated with gait speed changes (i.e. acceleration or deceleration). For data acquisition, healthy subjects were asked to perform volitional speed changes between 0, 1, and 2 Km/h, during treadmill walk. Simultaneously, the treadmill controller modified the speed of the belt according to the subject's linear speed. A classifie...

In this issue, a study by Kano et al report on the use of gait speed as a marker of frailty in an older population undergoing transcatheter aortic valve replacement (TAVR) and demonstrated its use to predict outcomes. Specifically, they used a multicenter Japanese registry to analyze the association between gait speed and mortality in 1256 older adults who underwent TAVR. The end points evaluat...

OBJECTIVE to investigate the association between gait speed and the cognitive score of elderly patients enrolled in a Basic Health Unit. METHOD a quantitative cross-sectional study with 203 elderly, a sample calculated based on the estimated population proportion. Data were collected using a sociodemographic and clinical questionnaire, gait speed test (GS) and the Mini Mental State Examinatio...

OBJECTIVES The objective of this study was to explore the associations between openness to experience and conscientiousness, two dimensions of the five-factor model of personality, and usual gait speed and gait speed decline. METHOD Baseline analyses were conducted on 907 men and women aged 71-82 years participating in the Cognitive Vitality substudy of the Health, Aging, and Body Composition...

Objectives: To analyze which gait parameters are primarily influenced by cognitive flexibility, and whether such an effect depends on the walking condition used. Design: Cross-sectional analysis. Setting: Tübingen evaluation of Risk factors for Early detection of Neurodegenerative Disorders. Participants: A total of 661 non-demented individuals (49-80 years). Measurements: A gait assessment wit...

BACKGROUND gait speed is associated with mortality among the elderly, but evidence for this in Japan is lacking. We investigated the impact of gait speed on mortality among younger-elderly people and determined whether daily walking modifies that association. SUBJECTS data were obtained from 2,105 community-dwelling individuals (990 men, 1,025 women) approaching age 65 who were free of heart ...

The purpose of this study was to investigate the effect of different mandibular positions on the body equilibrium by measuring the gait rhythm. Twelve young healthy subjects volunteered to participate in this study. Subjects were instructed to walk for a 18m distance with the mandible guided at six different positions by occlusal splints. The gait was recorded at fast, ordinary and slow walking...

BACKGROUND/AIMS Gait speed is cross-sectionally associated with attention and psychomotor speed in older community dwellers. It is unclear if gait speed predicts decline in these cognitive domains over time. METHODS Usual gait speed (m/s) over 6 m was measured at baseline in 2,776 Health, Aging and Body Composition Study participants (mean age +/- SD 73.5 +/- 2.8 years, 53% women, 37% blacks)...
