title: A home-based resistance-training program using elastic bands for elderly patients with orthostatic hypotension.
abstract: Falls are a common hazard in the elderly. Orthostatic hypotension (OH) is prevalent in older patients and contributes to the high incidence of falls. Our aim was to test whether a home-based resistance-training program (HBRT) using elastic resistance bands could safely and effectively increase muscle strength and functional ability, and attenuate the orthostatic fall in blood pressure. Eight subjects (> 60 yrs) underwent orthostatic provocations; muscle strength testing (isometric and dynamic), and a functional test of gait and mobility (Timed Up & Go), at baseline and following 8 weeks of training. Ten exercises were assigned and customized to each participant. At 8 weeks, significant increases occurred in dynamic strength in the chest press ( p = 0.017), quadriceps extension ( p = 0.017), and leg press (p = 0.025); no significant differences occurred in isometric strength or in blood pressures. Functional mobility increased in 7 of 8 subjects. There were no falls during the investigation period.
  
  
  CONCLUSIONS
  A HBRT program using elastic resistance bands effectively increases dynamic muscle strength in elderly individuals with OH. Although no changes occurred in orthostatic blood pressures, which could be attributed to the limited length of the program, this therapy may be recognized as a safe method to improve strength, functional ability, and promote physical activity - variables that can reduce the incidence of falls and enhance the quality of life in this population.
