The purpose of this study is to compare the effectiveness of these two exercise interventions and an education control group. Effectiveness will be assessed by studying the impact of interventions on (1) composite measures of stability (gait and balance), (2) fall self-efficacy, and (3) patient acceptance. Given the well-documented links between falls and fall-related injuries (ultimate outcomes) our study will focus on stability (intermediate outcome). Because falls and fall-related injuries are relatively rare events, examining stability as an outcome will allow us to have sufficient power to test our hypotheses with a relatively small sample size thereby decreasing the cost and duration of the study without sacrificing the rigor of the research design.
