Tape Tread - The Effect of McConnell Taping on the Quadriceps Angle
Floor Location : M 087 H
Patellofemoral pain syndrome (PFPS) is a chronic overuse conditions affecting the anterior part of the knee. A high quadriceps angle (q angle) contributes to PFPS by increasing the lateral pull of the quadriceps femoris muscle on the patella. This results in mal tracking of the patella as it does not travel over the front of the knee as it should. McConnell taping is a possible treatment method for PFPS with little research on the kinematic changes occurring when used. In this investigation, changes in the knee when walking and standing were examined by using the McConnell taping method and results were recorded with and without tape and then analyzed. Our results showed an average increase in q angle of 4.8 degrees in the right leg and 4.7 degrees in the left leg at standing. At midstance a mean increase of 2.6 degrees in the right leg and an average increase of 3.0 degrees was observed. A statistically significant difference in q angle while standing was observed between the no tape and the tape group in both legs, left leg: (t=3.1667, p=0.009) and right leg: (t=3.5052, p=0.0049). Since a raised q angle puts higher stress on the knees our results suggests that McConnell taping is not an effective treatment of PFPS and may even exacerbate the pain with long-term use. In this experiment a low cost method of analyzing walking was developed that can be used in physiotherapy clinics and doctor’s offices where gait analysis is not readily available.
