Filter by:Patellofemoral pain syndrome (PFPS) is the most common running injury and is believed to be associated with higher than normal knee joint loading. Footwear has been developed that may decrease these knee loads in healthy subjects, but their effects on patients with PFPS are unknown. In this study, we aim to test the effects of such footwear on patients with PFPS. We hypothesize that patients who receive the footwear intervention will show a decrease in knee joint loading, and consequently will show improvements in subjective levels of perceived knee pain over a period of six weeks compared to a control condition.
With this study two different therapeutic exercise regimens will be compared in patients with anterior knee pain (patellofemoral pain syndrome, PFPS).
To determine the utility of the Wii Fit TM interactive video game program in patellofemoral symptom resolution, development of increased muscle strength and flexibility as a result of increased compliance with home exercises in adolescent females with patellofemoral syndrome.
Background: - Patellofemoral pain syndrome is one of the most common knee problems. It is characterized by pain in the front of the knee that is aggravated by deep knee flexion, prolonged sitting, and repetitive movement. The most widely accepted theory regarding the source of this pain is that a force imbalance around the knee puts extra stress on the area, leading to pain. - Researchers are interested in learning more about the muscle groups around the knee to better understand the causes of knee pain. Objectives: - To obtain more information on how muscles, tendons, and bones work together to cause motion in the knee, both in the normal state and after immobilizing certain muscles around the knee. Eligibility: - Healthy individuals between the ages of 18 and 55, who have no current or chronic muscle, bone, or joint problems and who have no implants or other problems that would prevent them from receiving a magnetic resonance imaging (MRI) scan. Design: - This protocol will be carried out over two visits, both of which will involve using standard MRI sequences to look at the knee at rest and in motion. - The first part will examine the knee under its natural state, with a standard MRI scan of the knee both at rest and in motion. - The second part will involve temporarily reducing the force producing capabilities of one of the extensor muscles in the knee. To do so, study doctors will inject lidocaine into the muscle, which will temporarily (for approximately 2 hours) block the force producing capacity of this muscle, and then perform the MRI scan....
Background Previous studies have a great discrepancy concerning the effects of quadriceps contraction on patellar lateral displacement and tilt in patients with patellofemoral pain syndrome. This discrepancy may be caused by lack of information regarding to classifications of patellofemoral alignment under quadriceps relaxed. We hypothesized quadriceps contraction has different effects on each type of patellofemoral malalignment. Methods The investigators expect to recruit 150 subjects with patellofemoral pain syndrome to participate in this study. All patients underwent computed tomography imaging of symptomatic knees, with and without quadriceps muscle contraction in 0°, 15° and 30° of knee flexion. Patellar lateral condyle index and patellar tilt angles of Sasaki and modified Fulkerson were measured to investigate the effect of quadriceps contraction on patellar repositioning.
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.
Anterior knee pain has been an enigmatic problem for orthopedic surgeons. Recent studies, as well as the clinical observation of the principle investigator have suggested that arthroscopic resection of the infrapatellar plica (IPP), a vestigial remnant from embryonic development of no known clinical or biological significance, may eliminate this pain. The mechanism whereby this pain is related to the IPP is unclear. This study will document the mechanical behavior of the IPP, its kinematics, as recorded on video among a group of subjects who are undergoing arthroscopy. Radiographic visualization of the observed behavior will be obtained by injection of contrast material, and then fluoroscopic recording of a standard series of motions. The plica will then be resected to avoid any possibility of residual symptoms related to its presence. Further fluoroscopy of the knee without plical attachment, will allow the kinematic behavior to be assessed. The procedure will then be terminated.
The purpose of this study is to determine whether the use of botulinum toxin A injected into the lateral thigh muscle improves knee function and reduces knee pain secondary to patellofemoral syndrome. The study hypothesis is that botulinum toxin + specific exercises will be superior to specific exercises alone in improving knee function and reducing knee pain in individuals with patellofemoral syndrome.
The purpose of this study is to investigate the muscle activity of gluteus medius and tensor fascia lata in health control group and patients with PFPS during submaximal isometric muscle contraction.The research question :Is there any difference of muscle activity of gluteus medius and tensor fascia lata between health control group and patients with PFPS during submaximal isometric muscle contraction ？Null hypothesis:There is no difference of muscle activity of gluteus medius and tensor fascia lata between health control group and patients with PFPS during submaximal isometric muscle contraction.
Objectives:The purpose of this study was to investigate the different effects among the quadriceps strength training, taping, and stretching exercise of iliotibial band in patients with patellofemoral pain syndrome by randomized control trial study. Method:An observer blind, prospective, factorial design randomized controlled trail. 90 young adults with patellofemoral pain syndrome were randomly allocated into one of three treatment groups: (1) Quadriceps strength training, (2) taping, and (3) stretch. Each group received treatment for 8 weeks. Hypothesis:Patients in quadriceps strength training group may get most outcomes in three groups
