View clinical trials related to Patellofemoral Pain Syndrome.
Filter by:We assume the etiology of patellofemoral pain syndrome is related to mechanical properties of tendon structures of the vastus medialis obliquus and vastus lateralis. Consequently, we will measure the electromechanical delay and some viscoelastic parameters of the two muscles. Besides, we will also investigate the effects of exercise training to the mechanical properties of the muscles.
Patellofemoral pain syndrome (PFPS) is a common knee disorder affecting physically active people. Despite the growing base of support for the early introduction of hip strengthening exercises into the rehabilitation of PFPS, there have been few randomized clinical trials comparing isolated hip to isolated quadriceps strengthening. The purpose of this study is to determine how different exercises affect pain, strength, muscle activity, and function in female subjects with patellofemoral pain. The researchers hypothesize that females diagnosed with PFPS who initially participate in a hip strengthening program will report a greater perceived level of function, greater strength, less pain, and improved neuromuscular activity than those who participate in a progressive quadriceps strengthening intervention.
The purpose of this study is to compare outcomes of combined chiropractic care in anterior knee pain patients with patellofemoral pain syndrome.
Overuse injuries are a major concern for physical active individuals. Study hypothesis is that an exercise programme based on known intrinsic risk factors can prevent overuse injuries in soldiers undergoing basic military training.
The purpose of the study is to investigate the prevalence of pain in the anterior part of the knee, amongst youngsters between 16 and 18 years of age. Furthermore, this trial intends to study the connection between the pain, hyperpronation of the foot and tight Achilles tendon. We want to find out if there is a need of an early effort in terms of information, training and/or support for the shoes.
Background：Patellofemoral pain syndrome（PFPS） is a common knee disorder characterized by anterior or retropatellar pain associated with activities that load the patellofemoral joint. Previous studies reveal that the vastus medialis obliquus（VMO） is an important dynamic medial stabilizer of the patellar. Insufficiency of the VMO leads to lateral shift of the patella and the increases the patellofemoral contact force. An in vitro study conducted by Hubbard JK. et al. claimed that there were no significant relationship between several morphologic characteristics of the VMO and the extent of patellofemoral joint deterioration. We consider that the condition might be different in vivo, so we chose ultrasonogrphy as the measurement tool to examine the morphology of the VMO in PFPS patients and healthy controls. Purpose：To determine if there are significant differences in several morphologic parameters of the VMO between patients with PFPS and healthy controls under 50. Method：31 PFPS patients and 31 matched healthy adults under 50 were recruited for the study. The HDI 5000 ultrasonography machine was used to evaluate morphologic parameters of the VMO, including the percent of patella attachment, fiber angle, the volume attached to the patella, and the change of shape of the VMO.
Quadriceps retraining, especially the vastus medialis oblique muscle strengthening, plays an important role in clinical management of patellofemoral pain syndrome. Vastus medialis oblique muscle roles as a dynamic stabilizer during the functional knee movement. It can generate a medial pulling force to patella against the lateral pulled by vastus lateralis. Thus it improves the patellofemoral joint compression force, reduces the knee pain, increases functional abilities, and patients’ quality of life. Could vastus medialis oblique be isolation by way of specific exercise without or minimize the recruitment of vastus lateralis？ According to human anatomy, vastus medialis oblique muscle origin from hip adductor magnus tendon, thus if incorporate hip adduction with knee extension as a selective means of training needs more researches. However, literature search shows that there are only a lot of EMG studies, so we need further clinical research to prove the treatment effect of this kind of strategy. The purpose of the study is to investigate the treatment effects of hip adduction combine knee extension exercise in patients with patellofemoral pain syndrome. We use muscle morphology of quadriceps muscle, pain, and functional abilities as the main outcome measures. Besides, we will make further compare with traditional knee extension exercise. The first hypothesis of the study is that patients with patellofemoral pain syndrome will get improvement in muscle morphology of quadriceps muscle, pain, and functional abilities after hip adduction combine knee extension exercise training . The second hypothesis is that patients with patellofemoral pain syndrome who receive hip adduction combine knee extension exercise training will get more improvement in muscle morphology of quadriceps muscle, pain, and functional abilities than patients who receive traditional knee extension exercise training. 90 patients with patellofemoral pain syndrome who less than 50 years old will be included in this study, and randomly distributed to hip adduction combine knee extension exercise group, knee extension exercise group, and control group. Following 8 weeks exercise training by an experimental physical therapist, ultrasound measurement of muscle thickness and cross-sectional area of vastus medialis oblique muscle, vastus lateralis muscle, and rectus femoris muscle component of quadriceps, 10cm-VAS patellofemoral joint pain evaluation, including VAS-U, VAS-W, and VAS-activity, and Lysholm scale scores will be measured. A two-way mixed ANOVA will be used to compare the mean differences between theses three groups. The study is aimed to provide an clinical evidence for evidence-based practice of rehabilitation in patients with patellofemoral pain syndrome.
Musculoskeletal conditions account for the third leading cause of health systems expenditure in Australia. Patellofemoral pain syndrome or pain about the knee cap is such a condition often treated in primary care. Both the individual and community are affected by this condition with an estimated 1 in 4 sufferers having problems and pain up to 20 years after first being afflicted. Importantly, it interferes with activities such as walking, jogging, gym classes and aerobics, which are often prescribed to prevent serious conditions of the heart, diabetes and obesity. Hence, it negatively impacts the health and well being of our nation. Two popular treatment options that are commonly prescribed for the management of patellofemoral pain syndrome are physiotherapy and foot orthotics. To date, there is some evidence supporting physiotherapy, especially current best practice methods, such as a combined program of therapeutic exercise, manual therapy and kneecap taping. There is a lack of evidence for the use of orthotics in treating patellofemoral pain syndrome. This project will conduct a randomised clinical trial to evaluate the relative benefits of orthotics as the sole treatment of patellofemoral pain syndrome and also when combined with physiotherapy. Factors associated with predicting the results of orthotic therapy will be studied to see if there are any tests that a health care practitioner can perform to provide information early on in a consultation regarding possible treatment outcomes. A cost-benefit analysis will also be conducted to calculate the relative economic merits of the treatments. A tangible outcome of this project will be the development of clinical guidelines for the most effective method of treating patellofemoral pain syndrome in primary health care.
This study will use magnetic resonance imaging (MRI) and ultrasound images to study how muscles, tendons, and bones work together to cause motion. The procedure is one of several tools being developed to characterize normal and impaired musculoskeletal function, with the goal of developing improved methods of diagnosis and treatment of movement disorders. Healthy normal volunteers must be age 5 to unlimited, with or without joint impairment, may be eligible for this study. Volunteers with joint impairment may not have serious injury to the joint being studied, previous surgery on the joint being studied, or extreme pain at the joint being studied. MRI uses a strong magnet and radio waves to create images of the inside of the body. The subject lies on a long narrow couch inside a metal cylinder (the scanner) for up to 3 hours while the scanner gathers data. Earplugs are worn to muffle loud noises caused by electrical switching of radiofrequency circuits used in the scanning process. A special pad or tube may be placed over or around the region being scanned to improve the quality of the data. The subject will be asked to repeatedly move a specific joint, such as the knee, for brief periods, usually less than 5 minutes. The subject can communicate via intercom with the person performing the study at all times during the procedure, and may request to stop the study at any time.
