Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators hypothesized that following the proposed training, older adults would improve their speed of taking a step in both single and dual task conditions, refine their ability to control balance when standing still and improve their self-reported physical function.

Study Groups

Balance Training Intervention
The Balance Training Intervention group received 24 training sessions over three months that included perturbation as well as dual-task exercises.
Balance Training Intervention
The intervention group participated in a total of 24 one-hour training sessions over a period of 12 weeks. The training program utilized different size balls as a general tool in a series of progressively more difficult exercises targeting sitting, standing, and gait-related balance control. The program included exercises at five different levels of progressively more challenging balance exercises. Levels 1-4 focused on voluntarily controlled balance exercises, whereas level 5 also included perturbation exercises to trigger automatic compensatory stepping responses. All levels included attention-demanding dual task exercises that required subjects to simultaneously perform motor and cognitive activities.
