This study looked at the effect of a single session of mild exercise in a group of cognitively unimpaired institutionalized elderly patients, aged 70+, on tests of cognitive performance. Results indicate that mild exercise, such as range-of-motion, does improve the ability to recall and that the effect lasts for at least half an hour. Mild exercise programmes appear to be a practical, low-cost nursing intervention that can enhance memory and independence. Programmes that are designed to meet individual needs and that are incorporated into daily routine and activities without imposing extra effort or inconvenience are more appealing to elderly patients. Exercise can be easily learned and implemented by nurses, personal care attendants or nurse aides. This is an extremely important consideration in a health care system that demands low-cost quality care.
