title: Therapeutic patellar taping changes the timing of vasti muscle activation in people with patellofemoral pain syndrome.
abstract: OBJECTIVE
  To examine the effect of the application of tape over the patella on the onset of electromyographic (EMG) activity of vastus medialis obliquus (VMO) relative to vastus lateralis (VL) in participants with and without patellofemoral pain syndrome (PFPS).
  
  
  METHODS
  Randomised within subject.
  
  
  METHODS
  University laboratory.
  
  
  METHODS
  Ten participants with PFPS and 12 asymptomatic controls.
  
  
  METHODS
  Three experimental taping conditions: no tape, therapeutic tape, and placebo tape.
  
  
  METHODS
  Electromyographic onset of VMO and VL assessed during the concentric and eccentric phases of a stair stepping task.
  
  
  RESULTS
  When participants with PFPS completed the stair stepping task, the application of therapeutic patellar tape was found to alter the temporal characteristics of VMO and VL activation, whereas placebo tape had no effect. In contrast, there was no change in the EMG onset of VMO and VL with the application of placebo or therapeutic tape to the knee in the asymptomatic participants.
  
  
  CONCLUSIONS
  These data support the use of patellar taping as an adjunct to rehabilitation in people with PFPS.
