title: The effect of textured insoles on postural control in double and single limb stance.
abstract: BACKGROUND
  Increased plantar cutaneous afferent information may improve postural control.
  
  
  OBJECTIVE
  To compare postural control measures between balance conditions with and without textured insoles.
  
  
  METHODS
  crossover trial.
  
  
  METHODS
  Research Laboratory.
  
  
  METHODS
  33 healthy subjects (27.4 +/- 9.1 yrs, 172.6 +/- 10.3 cm, 75.4 +/- 16.4 kg).
  
  
  METHODS
  Subjects performed 24, 10-second bipedal and unilateral stance balance trials with eyes opened and eyes closed, with and without a textured insole in subjects' shoes.
  
  
  METHODS
  Average velocity and area of center of pressure (COP) excursions.
  
  
  RESULTS
  We observed an interaction among balance conditions during bilateral stance, but not during unilateral stance. On average, subjects exhibited greater area and velocity of COP excursions with eyes closed compared to eyes opened. Significant differences in area and velocity of COP excursions were observed during bilateral stance only when subjects were not wearing textured insoles. There were no significant differences while subjects balanced in bilateral stance with textured insoles.
  
  
  CONCLUSIONS
  Increased afferent information from textured insoles improves postural control in bilateral stance.
