Fall Prevention Exercises With or Without Behavior Change Support for Community-Dwelling Older Adults: A Two-Year Follow-Up of a Randomized Controlled Trial. 
This study investigates the effectiveness of two fall prevention exercise interventions targeting physical performance, activity level, fall-related self-efficacy, health-related quality of life, and falls: the Otago Exercise Programme (OEP) with and the OEP without behavior change support.  In this randomized controlled trial (RCT), 175 participants were randomised into two intervention groups and one control group.  A total of 124 community-dwelling older adults over the age of 75 who needed walking aids or home support participated in the two-year follow-up.  The OEP with and the OEP without support for behavior change displayed no long-term benefits on physical performance, fall-related self-efficacy, health-related quality of life, and falls compared to a control group.  Although no significant differences were detected between the groups, the results implied the control group's physical activity level decreased compared to the intervention groups at two-year follow up.
