Different Squatting Modes in the Rehabilitation of Patellofemoral Pain Syndrome:A Prospective Randomized Controlled Trial
This study take 84 patients with Patellofemoral Pain Syndrome in Peking University Third Hospital during January to September in 2023 as subjects, aiming to explore the efficacy and intervention effects of three different static squat modes including straight leg raise, wall squat, direct squat and wall squat assisted by elastic bands for patients with PFPS, in order to providing theoretical basis and effective guidance for future home rehabilitation of patients with PFPS combined with mobile health.
Background：Static squat has been widely used in the treatments of patellofemoral pain syndrome (PFPS), but no study has assessed which static squat modes is more effective .This study aimed to compare the effects of three different static squat modes on patients with patellofemoral pain syndrome .
Methods：Investigators included 84 patients with patellofemoral pain syndrome, a 6-week training period using a mobile phone app with angle recognition function, patients were devided into 4 groups based on different static squat modes. Kujala score, Lysholm score, VAS-W score, VAS-U score,thigh circumference, peak torque of knee extension, and peak torque of knee flexion on the affected side were used to assess efficacy.Two-way ANOVA was conducted to determine the differences within and between groups.Paired-samples t-test was used for intergroup comparisons, and one-way ANOVA was applied for intergroup comparisons. Chi-square tests were performed on categorical data.
Inclusion Criteria:
Meet the diagnostic criteria of PFPS.
Age between 20 and 45 years (to reduce the risk of suffer from patellofemoral joint bone joint)
Have no other treatments before the experiment.
Exclusion Criteria:
Patients with a history of knee surgery.
With other lower limb injuries such as meniscus tear, bursitis, ligament injury, patellar tendon injury, joint degeneration, etc.
With a history of dislocation and subluxation of patellofemoral joint.
With cardiovascular vessels, lung, kidney and other important organs.
