Abstract

Background: McConnell recommended that patellar tape be kept on all day, until patients learn how to activate their vastus medialis obliquus (VMO) during an exercise program. This application may pose problems because prolonged taping may be inadvisable for some patients or even contraindicated owing to skin discomfort, irritation, or allergic reaction. Hypothesis: Wearing patellofemoral tape for a shorter duration during an exercise program would be just as beneficial as a prolonged taping application. Study Design: Prospective cohort. Methods: Twelve patients and 16 healthy people participated. Patients underwent short-period patellar taping plus an exercise program for 3 months. Numeric pain rating, muscle strength of the knee extensors, and electromyogram activity of the vastus lateralis and VMO were evaluated. Results: There were significant differences in electromyogram activity (P=.04) and knee extensor muscle strength (P=.03) between involved and uninvolved sides before treatment. After treatment, pain scores decreased, and there were no significant differences between involved and uninvolved sides in electromyogram activity (P=.68) and knee extensor strength (P=.62). Before treatment, mean VMO activation started significantly later than that of vastus lateralis, as compared with the matched healthy control group (P=.01). After treatment, these differences were nonsignificant (P=.08). Conclusion: Short-period patellar taping plus an exercise program improves VMO and vastus lateralis activation. Clinical Relevance: A shorter period of taping for the exercise program may be as beneficial as a prolonged taping application. © 2009 The Author(s).
