The benefits of increased physical activity in adults of any age are many. It is hypothesized that wearing a pedometer can motivate older adults to increase and sustain a higher level of ambulatory activity and improve measures of functional status.
A prospective observational walking program using pedometers, goal orientation, and educational materials. Participants were given pedometers with the screen covered to measure baseline steps. The pedometer screen was then uncovered for 4 weeks and participants encouraged to increase daily steps by 5% weekly. The pedometers were removed for 2 weeks and then returned with the screen covered to measure maintenance of activity.
Six senior-living facilities in the Saint Louis area.
A total of 36 ambulatory adults aged 65 or older.
The primary outcome measurement was average daily steps. Secondary outcomes included scores on the "Timed Up and Go," Tinetti Gait and Balance Evaluation, functional reach, 2-minute walking distance, 30-second leg-lift repetitions, grip strength, Geriatric Depression Scale (GDS), and Quality of Life Scale.
The average number of daily steps increased from 2992 to 3670 over a 4-week period, a 22.7% increase (P = .035). The average daily steps were not sustained once the pedometer was removed for 2 weeks. The Timed Up and Go decreased from 12.1 to 11.2 seconds (P = .014), 30-second leg lifts increased from 22.7 to 26.3 repetitions (P < .001), and 2-minute walking distance improved from 313.7 to 330.3 feet (P = .014) at study completion. No improvement was seen in grip strength, functional reach, GDS, or quality of life.
Pedometers are a successful motivational tool to increase ambulatory activity in older adults with a secondary benefit in functional status measures.
增加任何年龄段成年人的身体活动都有很多好处。据推测，佩戴计步器可以激励老年人增加并维持更高水平的活动能力，并改善功能状态的衡量标准。
一项使用计步器、目标设定和教育材料的前瞻性观察性步行计划。参与者在开始时佩戴计步器，屏幕被遮盖以测量基础步数。然后，将计步器屏幕揭开 4 周，鼓励参与者每周增加 5%的日常步数。将计步器取下 2 周，然后再次戴上计步器，屏幕被遮盖以测量活动的维持情况。
圣路易斯地区的 6 个老年生活设施。
共 36 名年龄在 65 岁或以上的能走动的成年人。
主要结果测量是平均每日步数。次要结果包括“计时起立行走”、Tinetti 步态和平衡评估、功能伸展、2 分钟步行距离、30 秒腿举重复次数、握力、老年抑郁量表（GDS）和生活质量量表的评分。
在 4 周内，平均每日步数从 2992 增加到 3670，增加了 22.7%（P =.035）。一旦计步器被取下 2 周，平均每日步数就无法维持。计时起立行走测试从 12.1 秒减少到 11.2 秒（P =.014），30 秒腿举次数从 22.7 次增加到 26.3 次（P <.001），2 分钟步行距离从 313.7 英尺增加到 330.3 英尺（P =.014）。握力、功能伸展、GDS 或生活质量没有改善。
计步器是激励老年人增加活动能力的成功激励工具，对改善功能状态衡量标准有次要益处。
