title: Effect of kinesiotaping, non-elastic taping and bracing on segmental foot kinematics during drop landing in healthy subjects and subjects with chronic ankle instability.
abstract: OBJECTIVE
  To evaluate the effects of kinesiotape, non-elastic tape, and soft brace on segmental foot kinematics during drop landing in subjects with chronic ankle instability and healthy subjects.
  
  
  METHODS
  Controlled study with repeated measurements.
  
  
  METHODS
  Three-dimensional motion analysis laboratory.
  
  
  METHODS
  Twenty participants with chronic ankle instability and 20 healthy subjects.
  
  
  METHODS
  The subjects performed drop landings with 17 retroreflective markers on the foot and lower leg in four conditions: barefoot, with kinesiotape, with non-elastic tape and with a soft brace.
  
  
  METHODS
  Ranges of motion of foot segments using a foot measurement method.
  
  
  RESULTS
  In participants with chronic ankle instability, midfoot movement in the frontal plane (inclination of the medial arch) was reduced significantly by non-elastic taping, but kinesiotaping and bracing had no effect. In healthy subjects, both non-elastic taping and bracing reduced that movement. In both groups, non-elastic taping and bracing reduced rearfoot excursion in inversion/eversion significantly, which indicates a stabilisation effect. No such effect was found with kinesiotaping. All three methods reduced maximum plantar flexion significantly.
  
  
  CONCLUSIONS
  Non-elastic taping stabilised the midfoot best in patients with chronic ankle instability, while kinesiotaping did not influence foot kinematics other than to stabilise the rearfoot in the sagittal plane.
