Adjunctive Effects of Heat vs Contrast Therapy With Otago Exercises on Patellofemoral Pain Syndrome

The goal of this clinical trial is to determine the adjunctive effects of heat therapy and contrast therapy when combined with the Otago exercise program in individuals with patellofemoral pain syndrome aged 18 to 40 years. The study aims to assess whether these interventions can help reduce pain and swelling, improve knee range of motion, and decrease functional limitations associated with patellofemoral pain syndrome. Researchers will compare two groups one receiving heat therapy with the Otago exercise program and the other receiving contrast therapy with the Otago exercise program to see which approach provides greater improvement in outcomes. Participants will undergo regular supervised sessions that include the assigned thermal therapy and a structured set of Otago exercises targeting lower limb strength, balance, and mobility.

Comparative Effects of Blood Flow Restriction Resistance Training Versus Blood Flow Restriction Cycling on Pain, Quadriceps Strength, and Functional Outcomes in Athletes With Patellofemoral Pain

This randomized controlled trial compares blood flow restriction (BFR) resistance training (leg press and seated knee extension at 30% 1RM) versus BFR cycling (stationary cycling at low resistance) in 60 athletes (aged 18-40 years) diagnosed with patellofemoral pain syndrome. Both interventions are delivered over 8 weeks (3 sessions/week) with a pneumatic cuff set at 80% limb occlusion pressure. Primary outcomes include pain intensity (NPRS), quadriceps strength (handheld dynamometer), and functional ability (Kujala Anterior Knee Pain Scale), assessed at baseline and post-intervention.

Influence of Training Surface and Mechanical Load on the Prevalence of Patellofemoral Pain in Recreational Runners

Background. Patellofemoral pain (PFP) is one of the most common causes of knee pain in recreational runners and is exacerbated by activities that load the patellofemoral joint. Although biomechanical differences between running surfaces and elevation profiles have been documented, the influence of terrain type and training load on PFP in non-professional runners remains poorly defined. Objective. To examine the association between predominant training terrain and the presence of PFP in non-professional runners, and to describe its functional severity. Secondarily, to analyze the relationship between terrain exposure, elevation, training load and volume with PFP, as well as the potential influence of previous knee history and footwear rotation. Methods. An observational, analytical, cross-sectional study conducted through an online survey targeting recreational runners. The primary outcome will be the presence of patellofemoral pain, defined according to the 2016 International Consensus, and functional severity will be assessed using the Spanish-validated Kujala Anterior Knee Pain Scale. Exposures will include the percentage of kilometers run on each terrain type, positive and negative elevation gain, internal load (session rating of perceived exertion × duration), training volume, and running pace. Potential confounders will include age, sex, body mass index, running experience, training frequency, previous knee history, lower-limb strength, accumulated elevation gain, and footwear rotation. Descriptive analyses and logistic regression models will be performed to identify independent associations. Expected results. To estimate the prevalence of PFP in recreational runners, identify terrain- and load-related factors associated with its occurrence, and define a predictive model to inform prevention strategies and training planning.

Ultrasound Examination of the VMO in Patellofemoral Pain Syndrome

The aim of this study is to examine in detail the ultrasonographic characteristics of the vastus medialis obliquus and vastus medialis longus muscles in individuals with patellofemoral pain syndrome and to compare these findings with those of healthy individuals. It is anticipated that the results obtained will contribute to a better understanding of the muscle-based mechanisms of PFAS and provide a scientific basis for the development of muscle-specific assessment and intervention strategies in physical therapy and rehabilitation practices.

AI Driven EX Versus Conventional in PFPS

This study aims to investigate and compare the effect of AI driven exercises program versus the conventional exercises therapy program on pain, function and dynamic knee valgus angle in treatment of patellofemoral pain syndrome.This study is randomized controlled trial and includes 40 participants .These participants divided into 2 groups (A, B), each group will be assessed with 3 measurments (vas ,dynamic knee valgus, Kujala Anterior Knee Pain Scale) and each group will receive difeerent treatments. The individuals in group A(study group) will preceive AI driven exercises program while the individual in group B will receive conventional exercises therapy program. Participants in the both groups are prescribed a 6-week comprehensive exercises program (3 sessions per week) day after day and assessment procedure will be performed pre and post treatmeant .
