Analysis of neuromuscular activation of the vastus medialis obliquus and vastus lateralis with the use of functional taping

Muscular and anatomical changes are mostly responsible for patella femoral syndrome (PFPS). Knowing that the quadriceps muscles are very important to stabilize the patella, studies have questioned the influence of the Vastus Medialis Oblique (VMO) in the patellar stabilization avoiding the PFPS. Many researchers have investigated the use of taping as a means of muscle activation. Objective: The present study aimed to analyze the use of functional taping to activate the VMO during the squat exercise. Method: The activity of the VMO and Vastus Lateralis (VL) was assessed by electromyography during squats and squats with adduction using functional taping. The sample composed for 39 individuals was divided into four groups: sedentary males and athletes, and females also divided into sedentary and athletes. Results: Although it has been found greater activation of VMO in comparison with the VL, with the applied methodology and variables, we could not demonstrate a statistical difference between groups in squats with and without the use of functional taping. However, it is important to emphasize that the lack of difference in the activation of VMO during squats with adduction and tapping suggest a positive effect of the tapping in muscle activation. This result is very important in the treatment of acute injuries where active movement is limited. Conclusion: Future studies should be done with other electromyography parameters and reflex activation in order to investigate the actual role of functional taping on muscle activation.
