Evaluation of a Balance-recovery Specific Falls Prevention Exercise Program
|Accidental Falls||Behavioral: Balance training (exercise) Other: Flexibility and relaxation exercise||Phase 1|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||Development and Evaluation of a Perturbation-based Balance-training Program for Older Adults|
- Ability to recover balance by stepping and grasping [ Time Frame: Before and after 6-week intervention ]
- Fall frequency; clinical measures related to balance and fall risk (e.g. FallScreen, Community Balance and Mobility Scale, balance confidence) [ Time Frame: One year post-intervention ]

Perturbation-based balance training.
Behavioral: Balance training (exercise)
Perturbation-based balance training. 30-minute sessions three times per week for six weeks.
Placebo Comparator: CON
Flexibility and relaxation training.
Other: Flexibility and relaxation exercise
30-minute sessions, three times per week for six weeks.
Physical activity and exercise have been shown to prevent falling in older adults, although the exact mechanisms by which exercise prevents falls is unclear. Compensatory stepping and grasping reactions are frequently used to prevent a fall to the ground following a loss of balance. Age-related impairment in these reactions may be related to an increased risk of falling. Therefore, the purpose of this study is to investigate means for reversing age-related impairment in compensatory stepping and grasping reactions. A training program involving perturbation-evoked reactions will be evaluated.
Comparison(s): Balance recovery ability before and after a 6-week training program will be assessed. Performance of the training group will be compared to a control group not receiving stepping and grasping training.
