Patellofemoral pain (PFP) is the most common chronic pathology in sports medicine and physiotherapy clinics. As pain and inflammation are the main symptoms of PFP, non-steroidal anti-inflammatory and analgesic medications are often utilized to decrease pain and inflammation; however alternative treatments are increasingly being sought due to the cardiovascular and gastrointestinal side effects of traditional pain medications. Most researchers advocate conservative treatment, though there is still insufficient clarity regarding the effectiveness of conservative treatment modalities. Dietary interventions for PFP have not received any attention in clinical literature, yet there is a growing body of evidence indicating that cherries have significant anti-inflammatory, antioxidant and pain-mediating effects. Therefore, the primary purpose of the proposed investigation was to test (using a randomized control investigation) the ability of a tart cherry juice blend to provide symptom relief in recreational athletes with PFP and to understand the biological and mechanical mechanisms behind any changes in PFP symptoms.
Early activation of lateral hamstrings (LH) in respect of medial hamstrings (MH) may cause abnormal knee abduction and external rotation moments in individuals. This situation may increase the risk of ligament injury and may be the reason for susceptibility of patellofemoral pain (PFP). The aim of this study is to compare the time delays in electromyographic studies between medial and lateral hamstrings in patients with PFP and asymptomatic subjects.
This study primarily aims to investigate arthrogenic muscle inhibition (AMI), an underlying mechanism in patellofemoral pain (PFP), which remain to date understudied. Although, studies have revealed that AMI needs to be eliminated before improvements in muscle strength can be achieved, to date quadriceps muscle inhibition in patients with PFP remains understudied. To date the influence of AMI on functional performance and the direct link to pain in patients with PFP remain unclear. This study aims to investigate the link between AMI to pain, functional performance and how an acute treatment can affect functional performance and pain.
Patellofemoral pain (PFP) is the most diagnosed condition in individuals with knee complaints. Studies revealed that one third of individuals with PFP suffer from persistent complaints, indicating that current treatments fail to prevent the chronicity of symptoms. Considering that current treatment-strategies of patients with PFP seem to be unable to avoid the development of chronic symptoms, the question arises if the underlying factors of PFP are understood sufficiently. Current research focuses predominantly on muscle strength assessment by means of a maximum voluntary contraction (MVC), even though, weakness might not only be caused by a reduced voluntary contraction but also by an involuntary ability to contract the muscle fully, which is named arthrogenous muscular inhibition (AMI). Although AMI has been proven to be present in a wide range of knee joint pathologies to date it remains unclear whether patients with PFP are weak or inhibited. It remains also unclear if there exists a causal link between AMI and biomechanical alterations. Previous studies investigated the influence of exercise treatment on muscular strength, function and pain. However, to date no study investigated the influence of the currently recommended exercise treatment on AMI. Thus, the analysis of the effect of a 6 week exercise treatment might yield further insights if a specific exercise treatment can reduce AMI, improve functional performance and reduce pain. Methods: The investigators will invite 40 participants with PFP and 40 healthy controls to take part in the study. As a basis investigation kinematic, kinetic measures, and surface electromyographic (sEMG) of 4 lower limb muscles will be taken during functional tasks. Muscle strength and AMI of the quadriceps, muscle flexibility, and a posture assessment of the patella as well as the foot will be carried out. All participants with PFP will then receive a 6 week exercise programme to follow. After six weeks, the participants with PFP will attend the Salford university, where they will be reassessed. Expected outcomes: The study will investigate if AMI is present in participants with PFP and if AMI is directly linked to functional performance. In addition this study will investigate if a specific exercise treatment can reduce AMI and improve functional performance.
The investigators have previously reported on patient utilization of an eRehab patient education web portal that utilizes streaming, clinician prescribed video instruction to motivate and inform patients in self-care of their orthopedic condition, focusing on the importance of a home exercise program. The greatest barrier to patient use of this web-based home exercise treatment plan was the initial access to the program. The purpose of this study is to compare an Internet-based patient education rehab portal (eRehab) to formal physical therapy (PT) in terms of patient costs and outcomes.
Pain at the front of the knee is a common condition treated by physical therapists. Treatment may consist of generalised strengthening exercises directed at the quadriceps muscle or specific retraining aimed at restoring motor control at the knee. This study compared these two exercise programs in a group of people who were painfree at the time to evaluate their effect on motor control. It was hypothesised that only the motor retraining program would influence motor control at the knee.
