Background and Objective: Patellofemoral pain syndrome is one of the most common lower limb disorders causing pain and dysfunction. The aim of this study was to investigate the effect of balance and perturbation training on pain and function and electromyographic factors of the knee muscles in women with patellofemoral pain syndrome.
methods: In this quasi-experimental study, 25 female with patellofemoral pain syndrome with a mean age of 32.96 ± 8.27 years were randomly divided into an experimental (n=11) and control(n=14) group. The experimental group performed a six- week balance and perturbation training (18 sessione). Electromyograhic (EMG) assessment of vastus medialis, lateralis and biceps femoris activation and visual pain scale (VAS) in stepping up and down task were completed at baseline and after six weeks. To analyze the data, an analysis of variance with 2-fold repeated measures was performed at the significance level of α = 0.5 using SPSS version 25 software.
results: The results showed that after six weeks of neuromuscular balance training and perturbation training, pain intensity (p < 0.001) and electrical activity of the vastus lateralis muscle in stepping down (p = 0.001) decreased significantly and electrical activity of the vastus medialis muscle increased in stepping up (p = 0.003) In people with patellofemoral pain syndrome.
Conclusion: Neuromuscular training improves pain and increases vastus medialis muscle activity and decreases vastus lateralis muscle activity in women with patellofemoral pain syndrome and likely improves patellar alignment and improves pain and may help rehabilitate people with femoral patellofemoral pain syndrome.
