title: Exercise leads to faster postural reflexes, improved balance and mobility, and fewer falls in older persons with chronic stroke.
abstract: OBJECTIVE
  To determine the effect of two different community-based group exercise programs on functional balance, mobility, postural reflexes, and falls in older adults with chronic stroke.
  
  
  METHODS
  A randomized, clinical trial.
  
  
  METHODS
  Community center.
  
  
  METHODS
  Sixty-one community-dwelling older adults with chronic stroke.
  
  
  METHODS
  Participants were randomly assigned to an agility (n=30) or stretching/weight-shifting (n=31) exercise group. Both groups exercised three times a week for 10 weeks.
  
  
  METHODS
  Participants were assessed before, immediately after, and 1 month after the intervention for Berg Balance, Timed Up and Go, step reaction time, Activities-specific Balance Confidence, and Nottingham Health Profile. Testing of standing postural reflexes and induced falls evoked by a translating platform was also performed. In addition, falls in the community were tracked for 1 year from the start of the interventions.
  
  
  RESULTS
  Although exercise led to improvements in all clinical outcome measures for both groups, the agility group demonstrated greater improvement in step reaction time and paretic rectus femoris postural reflex onset latency than the stretching/weight-shifting group. In addition, the agility group experienced fewer induced falls on the platform.
  
  
  CONCLUSIONS
  Group exercise programs that include agility or stretching/weight shifting exercises improve postural reflexes, functional balance, and mobility and may lead to a reduction of falls in older adults with stroke.
