Relationship between knee extension strength and gait styles in patients with dementia.

This study aimed to investigate the relationship between knee extension strength and gait performance with walking aids and the threshold level of strength to predict gait performance with walking aids in patients with dementia using ordinal logistic modeling.This cross-sectional, observational correlation study was conducted in 56 hospital inpatients with dementia. Knee extensor strength was measured using a hand-held dynamometer.

Impact of dementia on behavioral independence and disturbance.

Aim: Decreasing behavioral independence levels and increasing frequencies of behavioral disturbances are the most problematic aspects for people with dementia. However, the relative effects of dementia on these factors are unknown. We investigated variability in behavioral independence and disturbance profiles of patients with dementia.
