Active clinical trials for "Patellofemoral Pain Syndrome"

The purpose of this study is to determine whether changing foot strike pattern from a rearfoot strike to a forefoot strike reduces chronic running-related knee pain. It is believed that switching foot strike pattern from a rearfoot strike to a forefoot strike pattern will reduce associated running-related patellofemoral knee pain.

This is a Randomized Controlled Trial (RCT) regarding the conservative treatment of patellofemoral pain (PFP) with an impairment based rehabilitation program. Those with PFP can have a variety of impairments, such as knee and hip muscle weakness, poor movement patterns, weak core activation and muscle tightness. Several recent RCT trials have looked at treating single impairments, but to date no RCT have address individualized patient impairments during a rehabilitation program. Abnormal muscle firing patterns have also been identified during functional tasks; such as jogging, stair climbing, and performing a single leg squat. Conflicting studies have produced changes to the quadriceps and hip muscle firing patterns with those with PFP. The abnormal activation patterns has been suggested to be why strengthening programs alone do not improve movement patterns during functional tasks for those with PFP. Patterned electrical neuromuscular stimulation (PENS) is a novel form of electrical stimulation that replicates proper firing patterns based off healthy electromyography patterns. The purpose of the study is to investigate the benefits of PENS with a impairment based rehabilitation program for the treatment of PFP. The rationale for this investigation is to assess the benefits of PENS with therapeutic exercise at improving altered firing patterns of the lower extremity muscles during functional tasks.

This study investigates if live feedback during home-based exercises will improve the ability to perform the exercises with the prescribed time under tension (TUT) per repetition compared with no feedback among adolescents with patellofemoral pain. The hypothesis is that adolescents who receive live feedback from BandCizer™ will have a mean TUT that is significantly closer to the prescribed TUT compared to the group not receiving feedback during the course of the intervention.

Assess pain, function, trunk and lower limbs kinematic during functional tasks after hip muscle strengthening versus hip muscle strengthening and sensory motor training in lower limbs.

The first purpose was to compare the difference between leg press exercise(LPE) and additional hip abductor and external rotator muscle strength training to leg press exercise(LPE+HAE) in muscle strength, hip kinematics during step down, pain severity and function for patients diagnosed with patellofemoral pain syndrome. The second one was to discover the relationship between the change in muscle strength performance and the difference of hip joint kinematics post treatment.

The investigators hypothesize that new runners participating in an 8 week strength and coordination training program prior to beginning to run will 1) display different coordination patterns , and 2) experience fewer injuries, compared to new runners who do not perform strength or coordination training prior to running.

Subjects between 14 and 40 years of age referred to physical therapy with a diagnosis of PFPS will be randomly assigned to one of two groups. The first group (PFPS) will be treated pragmatically. The second group (PFPS+DN) will receive the same pragmatic approach with the addition of dry needling intervention. The dry needling intervention will be delivered based on the treating physical therapist's examination of the patient's soft tissue mobility deficits, muscle activation deficits, or referred pain patterns.

The participants will be prepared for image-capture data collection by putting four squared markers, each 4 cm in diameter, will be attached to their leg at three locations while the subject in this position: (1) proximal to a quarter of the distance along a line joining the greater trochanter to the lateral knee joint line, (2) over the neck of the fibula, (3) over the proximal part of the lateral malleolus. A fourth marker will be attached over the iliotibial tract adjacent to the superior border of the patella when the subject in a sitting position. Each participant will seat on the end of an orthopedic assessment plinth and blindfolded . Each subject will be asked to extend his/her leg and make two angles arbitrarily from the resting position (90º) to the full extension. Photos will be taken, while they keep their leg at each position for five seconds.The bubble inclinometer will be attached to the patient leg at the resting position 90 º knee flexion. The tested leg will be passively moved by the researcher through 20° to 60° of knee extension from a starting knee angle of 90° to a target angle which will be measured by the bubble inclinometer , the participant then actively held the leg in this position for 5 second. A photograph of the leg in the target position will be taken using the camera which will be positioned 185 cm from the subject and 65 cm from the ground The leg will then be passively returned to the starting angle, and the participant will be instructed to actively move that leg to the target angle and hold it in this position another photograph will be taken, and the participant will be instructed to move the leg back to the starting position , the process will be repeated 3 times for each target angle with rest time 5 seconds between shots. After completing the procedure for all subjects, the test and replicated angles will be measured using the AutoCAD software and determine the center of the markers. Also , same angles will be measured via clinometer smart phone application in those patients to assess its validityand reliability where the participant will hold the leg for five seconds for each angle where this process will be reapeated for three times for each angle.

The aim of the study is to compare the efficacy of kinesio taping treatment and knee orthosis treatment in Patellofemoral Pain Syndrome (PFAS). 54 patients were included in the study and the patients were divided into 3 groups as kinesio taping group (KTG) (n=18), orthotics group (OG) (n=18) and control group (CG) (n=18). A progressive exercise program was applied to all groups and patients were treated 2 days a week for 6 weeks.While kinesio taping was applied to KTG in each session, knee orthosis was given to OG and they were asked to use it for 6 weeks. Visual Analogue Scale (VAS), Kujala Score, Knee injury and Osteoarthritis Outcome Score (KOOS), isokinetic strength test (IST) and joint position sense (JPS) test were used in the evaluation.

The purpose of the study is to compare the effects of routine physical therapy with and without core stability exercises on pain and range of motion, in patients with patellofemoral pain syndrome. The spine, abdominal region, pelvis, hips, and proximal lower extremities, are defined as the core of the body. The effects of core muscle strengthening have been proven as an effective method of management in various cases. The knee is the frequently injured joint in core instability with the decreased hip strength. Deficiency in the control of the neuromuscular system of the body's trunk or "core" may affect the stability of the lower extremity, which can lead to injury in the tibiofemoral or patellofemoral joints.
