MedlinePlus consumer health information
Study Type: Interventional
Study Design: Treatment, Randomized, Open Label, Placebo Control, Parallel Assignment, Efficacy Study
Secondary Outcomes: Fall frequency; volitional stepping and grasping reaction time; clinical measures related to balance and fall risk (e.g. FallScreen, Community Balance and Mobility Scale, balance confidence)
Expected Total Enrollment: 63
Study start: September 2005; Expected completion: December 2008
Last follow-up: March 2008; Data entry closure: March 2008
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. Specifically, two different training methods will be investigated: one involving perturbation-evoked reactions, and one involving volitionally executed reactions.
Comparison(s): Balance recovery ability before and after a 6-week training program will be assessed. Performance of the two training groups will be compared to a control group not receiving stepping and grasping training.
