BACKGROUND Functional independence with aging is an important goal for individuals and society. Simple prognostic indicators can inform health promotion and care planning, but evidence is limited by heterogeneity in measures of function. METHODS We performed a pooled analysis of data from seven studies of 27,220 community-dwelling older adults aged 65 or older with baseline gait speed, follow...

Walking speed is a fundamental indicator for human well-being. In a clinical setting, walking speed is typically measured by means of walking tests using different protocols. However, walking speed obtained in this way is unlikely to be representative of the conditions in a free-living environment. Recently, mobile accelerometry has opened up the possibility to extract walking speed from long-t...

OBJECTIVE The brain is one of the main targets of hypertension. However, little is known about the relation between hypertension and motor performances. We studied the association between hypertension and walking speed in a cohort of elderly people. METHODS Analyses are based on participants (65-85 years) from the Dijon (France) center of the Three-City study (n = 3604), followed every 2 year...

The purpose of this study was to evaluate the test-retest reliability of walking speed, stride time and stride length variability using a feedback-controlled treadmill. Ten subjects performed 3 trials of walking experiment for 5 min with a feedback-controlled treadmill. To check the reliability of gait parameters such as walking speed, average and variability (i.e. coefficient of variance, CV) ...

BACKGROUND Walking can improve functional status, and a pedometer and goal setting can increase walking and, potentially, gait speed. The efficacy of pedometer use and goal setting for increasing step counts among overweight and obese adults with multiple comorbid conditions has not been evaluated. METHODS We recruited and randomly assigned obese or overweight adults with multimorbidity to im...

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...

OBJECTIVE To evaluate if Geriatric Interdisciplinary Home Rehabilitation could improve walking ability for older people with hip fracture compared with conventional geriatric care and rehabilitation. A secondary aim was to investigate the postoperative length of hospital stay (LOS). DESIGN Randomized controlled trial. SETTING Geriatric ward, ordinary housing, and residential care facilities...

BACKGROUND Muscle co-activation plays an important role in enhancing joint stability for movement regulation during motor learning activities. In normal aging, greater muscle co-activation is induced during gait in elderly adults. This study investigated age-related changes in muscle co-activation and spatio-temporal parameters during gait and identified the relationship between muscle co-activ...
