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).

Objective The purpose of this study is to determine the effectiveness of the diffusion-weighted magnetic resonance imaging (DWI) of the differentiation of benign and malignant testicular masses. Methods Fifteen male patients who admitted to our clinic with the diagnosis of testicular mass detected by ultrasound were enrolled to this study. The patients were between 20 and 61 years old (mean 25.7). Apparent diffusion coefficient (ADC) values were measured from ADC maps of lesion and normal testicular tissue. In addition, mean signal intensity (SI) measurements were obtained by using b: 1,000 of normal testicular tissue and lesion with three regions of interest (ROI). SI ratio values are obtained by dividing the value lesion SI to the normal testicular parenchyma SI. Histopathology of orchiectomy materials and ADC values and lesion SI rates were compared statistically. Results There were no significant correlation (p = 0.97) between ADC values of benign and malign lesions and histopathological diagnosis in Student's t test. There were statistically significant relationship with the histopathology of the lesion and the SI ratio in Student's t test (p = 0.027). Conclusions DWI is an effective method in differentiation of benign and malignant testicular masses. Important information can be obtained about nature of testis masses with quantitative measurements of the ADC and ratio of SI. © Springer-Verlag Wien 2012.
