The purpose of this paper was to review existing literature on exercise interventions to improve postural stability in older adults in order to assist with the development of a novel intervention with the same function. A brief review of balance changes with aging is followed by a summary of the methods and findings of various interventions. Many types of interventions are discussed, including resistance training, balance training, t'ai chi, and whole body vibration. The studies show promising results, but none utilize the approach of the proposed intervention. This intervention being developed involves the use of a weighted vest to raise one's center of mass, creating a more unstable posture. Performing exercises or daily activities with the vest may improve balance by training muscles in unsteady conditions. The intervention principles to improve postural stability in older adults are beneficial to the foundation of future studies.
