“…Mobility disability is a dynamic condition and transitions between different levels of ability to walk 1/4 mile are common among older adults. 17 Interventions can improve objective ability to walk 1/4 mile; further studies are needed to determine if improvements in self-reported walking ability are associated with corresponding decreases in mortality and health care utilization. In addition, future studies should compare the performance of walking difficulty with other methods of screening risk of disability, death, and future utilization.…”

“…Some researchers have focused on endurance, suggesting that individuals who are unable to walk 400 m at once have a greater level of disability than those individuals who can walk for this extended distance [30]. Others have used both, suggesting that speed on a 4 m walk test can predict success on a 400 m walk test for older adults [31].…”

Abstract-Much is known about human walking, but it is not known how walking is used during typical activities. Since improving walking ability is a key goal in many surgical, pharmacological, and physiotherapeutic interventions, understanding typical community mobility demands regarding the length of walking bouts, the number of sequential steps frequently performed, and the duration of common nonwalking (rest) behavior seems prudent. This study documents the gait of daily living in 10 nondisabled employed adults to define walking bout duration, sequential step counts, and length of rest periods over a 2-week period. Subjects wore a StepWatch™ Activity Monitor (OrthoCare Innovations; Mountlake Terrace, Washington) that counted steps in each 10-second time window. Custom code summed sequential steps, periods of walking behavior (bouts), and periods without steps (rest). Sixty percent of all walking bouts lasted just 30 seconds or less; a 2-minute walking bout was just 1 percent of total walking bouts. Forty percent of all walking bouts were less than 12 steps in a row, and 75 percent of all walking bouts were less than 40 steps in a row. Rest periods were predominantly very short, with half of all rests periods lasting 20 seconds or less. The community mobility demand for nondisabled employed adults appears to involve frequent short-duration walking behavior with low numbers of sequential steps strung together and many shortduration nonwalking (rest) behaviors.

“…These periods of transition or functional mobility pose challenges to posture and balance that could result in a fall. Therefore, it stands to reason that reduced participation in activities of daily living (ADL), both in and out of the home, may result from challenges with balance and functional mobility (Gill, Allore, Hardy, & Guo, 2006).…”

Background: Falls are the fifth leading cause of death for adults aged 65 years and older. Several intrinsic and extrinsic fall risk factors have been identified, butthere is less understanding of the impact of a fear of falling on falls. Seventy percent of recent fallers and 40% percent of non-fallers report a fear of falling. Therefore, the purpose of this study was to examine the correlation between a fear of falling and a history of falls, as well as the impact on the functional independence of community-dwelling older adults receiving home health services.
