How do sleep disorders impact gait quality and fall risk in older adults?
Sleep problems are very common in people over 65 and are tied to a greater risk of falling. Research shows that these sleep issues affect how well a person controls their balance and moves safely, which increases the likelihood of a fall. This connection happens even when the person's overall walking speed stays the same.
What the research says
A study of 758 older adults found that those with sleep problems had lower gait quality, meaning their balance and movement control were worse. This group also experienced more total falls and more serious falls compared to those without sleep issues 4. The study noted that while walking speed did not change, the quality of the steps and stability did decline 4.
Sleep disorders also cause changes in the brain that may explain these physical risks. A meta-analysis of 19 studies found that people with sleep disorders have global glymphatic impairment, which is a dysfunction in how the brain clears waste 3. This brain issue is seen across many types of sleep problems, suggesting a shared neural feature that could affect neurological function 3. Additionally, genetic research shows that sleep disorders share risk factors with other conditions affecting the central nervous system 2.
What to ask your doctor
- How can we improve my sleep quality to reduce my fall risk?
- What other factors besides sleep might be affecting my balance and gait?
- Are there specific exercises or therapies that can help improve my gait quality?
- Should I be screened for sleep disorders if I have fallen recently?
