title: The effect of two mobilization techniques on dorsiflexion in people with chronic ankle instability.
abstract: OBJECTIVE
  To compare the effect of two manual therapy techniques, mobilization with movement (WB-MWM) and talocrural manipulation (HVLA), for the improvement of ankle dorsiflexion in people with chronic ankle instability (CAI) over 48 h.
  
  
  METHODS
  Randomized controlled clinical trial.
  
  
  METHODS
  University research laboratory.
  
  
  METHODS
  Fifty-two participants (mean ± SD age, 20.7 ± 3.4 years) with CAI were randomized to WB-MWM (n = 18), HVLA (n = 19) or placebo group (n = 15).
  
  
  METHODS
  Weight-bearing ankle dorsiflexion measured with the weight-bearing lunge. Measurements were obtained prior to intervention, immediately after intervention, and 10 min, 24 h and 48 h post-intervention.
  
  
  RESULTS
  There was a significant effect × time (F4,192 = 20.65; P < 0.001) and a significant time × group interactions (F8,192 = 6.34; P < 0.001). Post hoc analysis showed a significant increase of ankle dorsiflexion in both WB-MWM and HVLA groups with respect to the placebo group with no differences between both active treatment groups.
  
  
  CONCLUSIONS
  A single application of WB-MWM or HVLA manual technique improves ankle dorsiflexion in people with CAI, and the effects persist for at least two days. Both techniques have similar effectiveness for improving ankle dorsiflexion although WB-MWM demonstrated greater effect sizes.
