Effect of Exercise on Negative Affect in Residents in Special Care Units With Moderate to Severe Dementia

Approximately 35% of individuals with dementia exhibit depression and/or anxiety symptoms, often manifested by symptoms of negative affect. Exercise has been associated with improved affect but has not been demonstrated to improve affect in residents of secured dementia units in long-term care facilities. This pilot study determined whether moderate-intensity, chair-based exercise was associated with changes in negative affect in residents in secured units. The sample included 36 patients from 2 nursing homes who participated in a 12-week, 30-minute moderate-intensity group exercise program thrice weekly. Affect, measured by the Philadelphia Geriatric Center Apparent Affect Rating Scale, was assessed at weeks 3 and 12, before and after each exercise session. Paired t tests assessed the immediate effect of exercise (before/after a session) and the long-term effect of exercise (study…
