Pedometer use increases daily steps and functional status in older adults

Area of Science:

• Gerontology
• Physical Activity and Exercise Science
• Public Health

Background:

• Increased physical activity offers numerous health benefits for adults of all ages.
• Older adults may benefit significantly from interventions promoting sustained ambulatory activity and improved functional status.

Purpose of the Study:

• To investigate if pedometers can motivate older adults to increase and maintain higher levels of physical activity.
• To assess the impact of pedometer use on functional status measures in older adults.

Main Methods:

• A prospective observational study involving 36 ambulatory adults aged 65+ across six senior-living facilities.
• Participants used pedometers for 4 weeks with a 5% weekly increase goal, followed by a 2-week removal period to assess maintenance.
• Outcomes included average daily steps, Timed Up and Go, gait and balance, functional reach, walking distance, leg lifts, grip strength, depression, and quality of life.

Main Results:

• Average daily steps increased by 22.7% (from 2992 to 3670) over the 4-week intervention (P = .035).
• Significant improvements were observed in Timed Up and Go (P = .014), 30-second leg lifts (P < .001), and 2-minute walking distance (P = .014).
• Activity levels and most functional measures did not sustain after pedometer removal.

Conclusions:

• Pedometers serve as a successful motivational tool for increasing ambulatory activity in older adults.
• The intervention showed secondary benefits in specific functional status measures, though not all were sustained.
• Further research may explore strategies for long-term maintenance of physical activity in this population.
