I can't access any of your links, as they just take me to a UW portal that I can't log into. Any chance you can just post the titel and author of hte study and I can look them up that way?
Sorry for the bad links. Here's some brief summaries...
PT Journal: Nov, 2010
Improved Fall-Related Efficacy in Older Adults Related to Changes in Dynamic Gait Ability
Who: PT professors from universities and medical centers (University of Florida, Borwn University, VA Medical Center, and others)
Limitations: no control group used.
After screening out 11 subjects due to ineligibility, 63 subjects (mean age 76 y.o.) with a h/o at least 2 falls in past 12 mo. enrolled in a 3-mo. exercise program. The exercise was tailored to their deficits (strengthening targeted platnar-flexors, dorsiflexors, quads, etc. as needed; others would receive endurance training, etc.). Each HEP progressed as the patient was able to. Berg, DGI and FES were used to evaluate them monthly. Significant improvements were noted in all measures on average (for example, Berg postintervention score was a little over 5 points higher on average).

LiFE Pilot Study: A randomised trial of balance and strength training embedded in daily life activity to reduce falls in older adults
(Various professors
Subjects: 34 who had 2 or more falls in past year.
Limitations: Larger randomized trial is needed.
Applied a "Lifestyle approach to reducing falls through exercise (LiFE)" which is a progressive program focuses on balance and strength training (5 home visits, 2 "booster visits") that the authors created.
Results: 12 falls in intervention group, 35 in the control group in 6 month follow up.

Journal of Geriatric PT:
Impact of participation in a wellness program on functional status and falls among aging adults in an assisted living setting.
April 2010
Limitations: No control group of nonexercisers, small sample size.
Investigated 36 adults (mean age 85 years old) categorized as either "regular" or "nonregular" exercise participants
19 and 17 respectively) during 12 mo. of participation in a multimodal wellness program. Berg, 6-min walk test, and a couple other tests were used in evaluation. Falls over this 12-mo period were noted. At 12-mo reassessment, regular exercisers scored slightly higher than the nonregulars in all measures. 75% of the falls that occurred were by the nonregular exercisers, 25% by the regulars.
------------------------
The American Geriatrics Society additionally lists a long falls prevention guidelines list, and topping their list is "direct interventions tailored to the identified risk factors, coupled with an appropriate exercise program," and they note that "good evidence was found that the intervention improves health outcomes and the conclusion is that benefits substantially outweigh harm."
For PTs who work sometimes or frequently with geriatrics, it's noteworthy.
