the effect of hip strengthening exercises and taping in patients with pfp with dynamic valgus

Conditions: Patellofemoral Pain; Valgus Deformity

Summary: the aim of the study is to investigate the effects of isolated quadriceps and hip strengthening exercises and both strengthening exercises and mulligan knee taping technique on pain, functional level and balance in patients with dynamic knee valgus and patellofemoral pain. in addition, in the groups investigators will create as randomized controlled, investigators give only strengthening exercise to one group and apply both exercise and taping to the other group and to investigate whether mulligan taping, which is applied in addition to exercise in the treatment, has an effect on valgus correction, pain, functional level and balance, and contributes to the literature. it will also become clear how effective the strengthening exercises will be in correcting the dynamic valgus, how much participants will reduce patellofemoral pain, and whether they have an effect on the functional level and balance. there are not enough studies in the literature on strengthening exercises in patients with patellofemoral pain with dynamic valgus. i̇nvestigators will contribute to the literature by evaluating the effect of hip and quadriceps strengthening exercises on dynamic knee valgus and patellofemoral pain with 2d video analysis method and evaluating the results concretely. in addition to the strengthening exercises that investigators will apply to the other group, our other research target is to evaluate the mulligan knee taping technique with 2d video analysis method and to investigate whether mulligan knee taping treatment has an effect on the correction of dynamic valgus.

a total of 34 patients with anterior knee pain and dynamic valgus will be included in the study and randomly divided into 2 groups as exercise and taping (n=17) and exercise (n=17). hip and quadriceps strengthening exercises will be applied to the patients in the exercise group 3 times a week for a total of 6 weeks, and both strengthening exercises and mulligan rigid knee taping will be applied to the patients in the exercise and taping group, again for 6 weeks and 3 times a week. if the participants in the study have bilateral anterior knee pain, the more symptomatic side will be included in the study. outcome measurements will be performed on the baseline (first day-before first treatment) and at the end of the 6 weeks treatment program. ncss (number cruncher statistical system) 2007 (kaysville, utah,usa) program will be used for statistical analysis. while evaluating the study data, descriptive statistical methods (mean, standard deviation, median, frequency, ratio, minimum, maximum) as well as the distribution of the data will be evaluated with the shapiro-wilk test. mann-whitney u test will be used in comparisons of two groups that cannot show normal distribution of quantitative data, and student's t test will be used in case of normal distribution. significance will be evaluated at the p\<0.05 level.

Eligibility criteria:
inclusion criteria: * anterior knee pain lasting more than 2 months * \> 10 degrees frontal plane valgus angle * at least 3 pains on the 10 cm vas scale in the last week * have symptoms for at least 2 months * patients aged 18 to 50 years * to have at least 2 of the pains that occur during squatting, climbing stairs, descending and sitting exclusion criteria: * neurological disease or sequelae * having an orthopedic injury that may affect lower extremity kinematics * pregnancy
