Filter by:Patellofemoral pain syndrome is due to dysfunctional dynamic knee valgus resulting from decrease in strength of hip abductors or abnormal rear-foot eversion with pes pronatus valgus. It is also associated with vastus medialis/vastus lateralis disbalance, hamstring tightness or iliotibial tract tightness.
This study aimed to investigate the effectiveness of Pilates exercises in Patellofemoral pain patients compared to hip and knee combined exercises in improving pain, muscle strength, flexibility, function and quality of life in short term.
Anterior cruciate ligament (ACL) injury is a prevailing problem among sports participants, especially in non-contact sports. Studies have reported that 70-84% of ACL injuries are non-contact in nature, and movements like changing in direction while running, cutting and pivoting on a planted foot have resulted in a majority of ACL injuries. Even after ACL reconstruction (ACLR) surgeries, study has reported a 30-50% prevalence of developing patellofemoral joint (PFJ) pain in 1-2 years post-operation. Whole body vibration (WBV) therapy has been gaining attention as an effective method of training in recent years. It has been proved to have a positive effect on improving muscle strength, muscle activities, muscle power and loading during drop jump. Though duration of WBV may differ according to the effect of interest, several studies have had positive results with a 8 week WBV therapy in increasing muscle strength, proprioception, and post-ACLR knee functions. Further investigation on the underlying mechanism and possible application are to be continued to explore more possibilities with the WBV therapy.
The objective of this study is to compare a novel 6-week strength training rehabilitation incorporating power exercises (STRIPE) program to a standard of care (SOC) program on short-term and long-term pain, subjective function, patellofemoral pain recurrence rates, and secondary outcomes (hip abduction and extension rate of torque development and single-leg squat kinematics). We hypothesize that participants with patellofemoral pain who complete the STRIPE program will have 1) decreased pain, 2) improved subjective function, 3) reduced patellofemoral pain recurrence rates, 4a) improved hip abduction/extension rate of torque development, and 4b) decreased hip adduction and pelvic drop during a single leg squat compared to participants who complete a SOC rehabilitation program.
The purpose of this graduate student research study is to investigate the relationship between limited ankle dorsiflexion and the potential effects on a single limb squat task in the Patellofemoral/Knee Pain population.
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.
