Primary Outcome Measures:

Ability to recover balance by stepping and grasping [ Time Frame: Before and after 6-week intervention ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

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 ] [ Designated as safety issue: No ]

Enrollment:	37
Study Start Date:	November 2005
Study Completion Date:	March 2008
Primary Completion Date:	March 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
PERT: Experimental Perturbation-based balance training.	Behavioral: Balance training (exercise) Perturbation-based balance training. 30-minute sessions three times per week for six weeks.
CON: Placebo Comparator Flexibility and relaxation training.	Other: Flexibility and relaxation exercise 30-minute sessions, three times per week for six weeks.

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.
