Taping on Knee Kinetics of Patients With Patellofemoral Pain Syndrome patellofemoral pain syndrome Sports medicine An often bilateral condition of insidious onset seen in young ♀ athletes Clinical Diffuse knee pain exacerbated by stair descent, squatting and prolonged sitting, patellar crepitus, knee joint stiffness, ↓ ROM. Ernst GP, Kawaguchi J, Saliba E (US Army--Baylor University, Program in Physical Therapy, Ft Sam Houston, Tex; University of Virginia, Charlottesville, Va), J Orthop Sports Phys Ther. 1999;29:661-667. The purpose of this study was to determine the effect of McConnell patellar taping on knee extensor extensor /ex·ten·sor/ (-ser) [L.] 1. causing extension. 2. a muscle that extends a joint. ex·ten·sor n. A muscle that extends or straightens a limb or body part. moment and power during a lateral step-up and vertical jump and the taping's effect on the height of a vertical jump. Fourteen women (mean age = 24.4 years) with a history of unilateral patellofemoral pain participated in the study. They were tested under 4 conditions: patellar taping, placebo patellar taping, no tape for the involved knee, and no tape for the uninvolved un·in·volved adj. Feeling or showing no interest or involvement; unconcerned: an uninvolved bystander. Adj. 1. knee. Kinematic kin·e·mat·ics n. (used with a sing. verb) The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it. and force platform data were collected for each subject while performing 3 lateral step-ups and 3 vertical jumps for each taping condition. Knee extensor moments were calculated using the inverse-dynamics approach. Patellar taping was found to have a significant effect on knee extensor moment and power. The taping resulted in a greater knee extensor moment and greater power (1.57 [+ or -] 0.32 N [multiplied by] m/kg and 3.47 [+ or -] 0.67 W/kg, respectively) than that found with no tape or placebo taping (no tape: 1.31 [+ or -] 0.39 N [multiplied by] m/kg and 2.79 [+ or -] 1.21 W/kg; placebo tape: 1.33 [+ or -] 0.30 N [multiplied by] m/kg and 2.70 [+ or -] 0.99 W/kg). There were no other differences between the other conditions. The uninvolved lower extremity had a significantly greater vertical jump height (25.69 [+ or -] 2.66 cm) than did the other 3 conditions, which did not differ significantly from each other (patellar tape: 23.33 [+ or -] 4.22 cm; placebo tape: 23.08 [+ or -] 4.20 cm; no tape: 23.45 [+ or -] 4.54 cm). The authors offered several possible explanations for the increase in knee extensor moment and power with patellar taping, including a change in quadriceps muscle lever arm, a change in trunk position, a change in vastus medialis oblique muscle activity, and a decrease in pain. The authors suggested that patellar taping may be useful for helping to activate the quadriceps femoris muscle
