Question: Does patellar taping change the amplitude of electromyographic activity of the vasti in a stair stepping task?
Answer: The results of this study indicate that the positive clinical effects of medially directed therapeutic tape are not due to changes in EMG amplitude of the vasti muscle. Thus other effects such as changes in timing of contraction of the vasti are more likely candidates for the mechanism of efficacy.
