Howe et al 2011 completed a literature review on exercise training in the elderly. Given that falls are one of the most traumatic injuries to happen to the older-adult population, exercise that minimizes falls and maintains independence should be researched and pursued. 34 studies met selection criteria. Interventions were primarily walking, strength training, balance exercise and coordination exercise. While interventions appear to improve balance compared to controls, most sample sizes were small, done over a short period of time with no follow up for long-term analysis. At this time, no one can conclusively say which exercises are superior to others or have more long-term effects in terms of maintenance of balance.
