title: The effect of a 5-week wobble-board exercise intervention on ability to discriminate different degrees of ankle inversion, barefoot and wearing shoes: a study in healthy elderly.
abstract: OBJECTIVE
  There is some evidence of an improvement in falls risk in the elderly after completing a wobble-board training program. This study examined the effects of wobble-board training on ability to discriminate between different extents of ankle inversion movements in a group of older subjects, tested wearing shoes and barefoot.
  
  
  METHODS
  A randomized, controlled, crossover pilot study.
  
  
  METHODS
  Canberra region, Australia.
  
  
  METHODS
  Twenty community-dwelling subjects aged 65 to 85 participated in this study; all were in good health with no known disorder of the musculoskeletal system.
  
  
  METHODS
  The accuracy with which subjects could identify a set of ankle inversion movements of different extents was measured, with testing conducted in an upright, weightbearing stance.
  
  
  METHODS
  The effects of a 5-week training program using a wobble board modified for data logging or a period of normal activity only were assessed. Subjects underwent an ankle movement discrimination test pre- and posttraining, with shoes on and off.
  
  
  RESULTS
  Greater improvement in ankle movement discrimination capability was made in subjects who underwent wobble-board training than in subjects who did not train (F(1,18)=11.2, P=.003). Active movements at the ankle were also significantly better discriminated throughout when subjects were wearing shoes than when barefoot (F(1,18)=40.6, P=.001).
  
  
  CONCLUSIONS
  Training with a wobble board provides a simple in-home intervention that improves ability to differentiate between extent of movements into ankle inversion in subjects aged 65 and older. Research on trip and fall frequency after wobble-board use is needed before such training could be widely used.
