Brief Summary:
This study aims to investigate the potential to train compensatory stepping and grasping reactions for the prevention of falls.

Condition or disease Intervention/treatment Phase
Accidental Falls Behavioral: Balance training (exercise) Other: Flexibility and relaxation exercise Phase 1

Detailed Description:

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.

Arm Intervention/treatment
Experimental: PERT
Perturbation-based balance training.
Behavioral: Balance training (exercise)
Perturbation-based balance training. 30-minute sessions three times per week for six weeks.

Primary Outcome Measures :
  1. Ability to recover balance by stepping and grasping [ Time Frame: Before and after 6-week intervention ]

Secondary Outcome Measures :
  1. 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 ]
