The Effect of Hip Strengthening Exercises and Taping in Patients With PFP With Dynamic Valgus

Not Applicable

Completed

• Conditions: Patellofemoral Pain; Valgus Deformity

• Registration Number: NCT06735586
• Lead Sponsor: Bahçeşehir University

Brief 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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Anterior knee pain scale	6 week	measures the index function. the lowest 0 takes the highest 100 value.

Secondary Outcome Measures

Name	Time	Method
Visual analog scale	6 week	İnvestigators will evaluate pain with the VAS scale.The lowest value will be scored as 0 and the highest value as 10.Those with a value of 3 or more will be included in the study. The first and last day will be evaluated.
Y Balance Test	6 week	Dynamic balance measurements of patients will be evaluated with Y balance test. In the test set up, 3 measuring tapes will be glued to the ground with an angle of 120 between them. The patient will be asked to stand on one foot at the intersection of these 3 tapes, reach with the tip of the toe in these 3 directions with the other foot, anterior, posteromedial and posterolateral, and return to the starting position.
Frontal plane projection angle	6 week	In our study, our participants will be evaluated with single leg squat test and 2D video analysis method on the first and last day.Individuals will be asked to stand on one leg and bend their knees. The dynamic knee valgus of the participants who are positioned in 45º-60º flexion and observed from the frontal plane for 5 seconds will be evaluated.
Patellar tilt test	6 week	It is used to assess the tension of the lateral retinacular structures. With the patient lying in the supine position with the knee fully extended, investigators will evaluate with 2 fingers or 4 fingers whether there is a difference between the medial and lateral vertical heights of the patella. A lateral tilt is considered positive if the lateral side height is less than the medial side height.
Muscle strength measurement	6 week	Muscle strength measurements will be made with MicroFET2 hand dynamometer, whose reliability has been proven as isometric muscle strength measurement. Knee extension, hip external rotation, hip extension, hip abduction muscle strength will be measured.
Hip external rotation and internal rotation E.H.A measurements	6 week	The patient is sitting with his legs hanging off the table from the knee, and the measurement will be made with a goniometer.
Q angle measurement	6 week	The q angle is the angle between the line extending from the anterior superior of the spina iliaca to the midpoint of the patella and the line extending from the midpoint of the patella to the tuberositas tibia while the patient is standing.
