Hypothesis
There is a significant research gap concerning comprehensive, nationally representative data on the prevalence of motor function impairments in older adults.
Conclusion
The study found that the prevalence of motor function impairments increases with age, highlighting the need for early intervention.
Supporting Evidence
- Weighted prevalence of impairments increased with advancing age.
- Chair stand impairment was most prevalent among those aged 65-69 years.
- Gait speed impairment was most prevalent among those aged 90 years and older.
- 11.8% of those aged 65-69 years were impaired in all four motor function domains.
- 64.0% of those aged 90 years and older were impaired in all four motor function domains.
Takeaway
As people get older, they often have more trouble with things like walking and standing up, which can make life harder for them.
Methodology
Data from Round 12 of the National Health and Aging Trends Study was used to assess motor function through objective physical function testing.
Limitations
The study may not capture all aspects of motor function impairments and relies on specific clinical thresholds.
Participant Demographics
Mean age of participants was 78.7 years, with 54.4% being women.

Confidence Interval
78.3-79.1
