Relationship between falls and stride length variability in senile dementia of the Alzheimer type
Nakamura T, Meguro K, Sasaki H.. Gerontology, 1996-01-01
Topic: Risk, prevention and care in population studies
In this study, 97 patients with senile dementia of the Alzheimer type (SDAT) in a nursing home were followed over a period of 2 years, and the relationship between falls and gait function was examined. The findings indicated that the number of fallers was significantly higher in moderate-stage SDAT patients than in the mild-stage patients. In the moderate-stage SDAT patients, walking speed and stride length, measured as indices to evaluate gait function, were significantly lower, and the stride length variability was significantly higher than in mild-stage patients. When comparing the gait indices of fallers and non-fallers by the severity of dementia, a significant difference was observed only in stride length variability. The gait abnormality associated with advanced severity in dementia is believed to be a factor affecting falling. In particular, stride length variability appeared to be an effective predictor of falling.
Key findings
- The findings indicated that the number of fallers was significantly higher in moderate-stage SDAT patients than in the mild-stage patients.
- In the moderate-stage SDAT patients, walking speed and stride length, measured as indices to evaluate gait function, were significantly lower, and the stride length variability was significantly higher than in mild-stage patients.
- When comparing the gait indices of fallers and non-fallers by the severity of dementia, a significant difference was observed only in stride length variability.
- The gait abnormality associated with advanced severity in dementia is believed to be a factor affecting falling.

How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 25 of the 58 points we could judge it on, which is 43 out of 100.
