The effect of lumbopelvic manipulation on electromyography parameters of gluteus medius and vastus medialis in patients with patellofemoral pain syndrome: A double-blind, placebo-controlled trial
Background
Patellofemoral Pain Syndrome is the most common cause of anterior knee pain, especially in active young people. This study aimed to evaluate the effect of lumbopelvic manipulation on electromyography parameters of gluteus medius and vastus medialis in patients with patellofemoral pain syndrome.
Methods
In this double-blind placebo-controlled randomized clinical trial study, 26 patients with a diagnosis of patellofemoral pain syndrome were randomly divided into two groups. The first group received Lumbopelvic manipulation and the second group was a control group that received placebo manipulation. Electromyography activity of vastus medialis and gluteus medius muscles were evaluated as primary outcomes during the single-leg squat; pain intensity during rest and functional tasks (step up, step down, single leg squat) were assessed by numerical pain rating scale. Functional status was evaluated by step-down test and the score of the Kujala patellofemoral questionnaire, as secondary outcomes. All evaluations were performed before and after the intervention, except pain intensity at rest and the Kujala patellofemoral questionnaire that were assessed before the intervention and one week after.
Result
In both groups, no significant difference was observed before and after the intervention in terms of average amplitude and the onset of gluteus medius and vastus medialis. However, in the lumbopelvic manipulation group, pain intensity during rest and functional tests significantly decreased compared to the control group. Functional status significantly improved in the lumbopelvic manipulation group, with no significant difference between group comparisons.
Conclusion
Lumbopelvic manipulation caused a reduction in pain intensity and improvement of functional status in the rehabilitation of patients with patellofemoral Pain Syndrome. However, it seems that this method could not change the EMG activity of muscles in these patients.
Implications for practice
•
The results of present study can help physiotherapists to understand the possible underlying pathomechanics of patellofemoral pain syndrome and more effective treatment of these group of patients.
期刊介绍：
The International Journal of Osteopathic Medicine is a peer-reviewed journal that provides for the publication of high quality research articles and review papers that are as broad as the many disciplines that influence and underpin the principles and practice of osteopathic medicine. Particular emphasis is given to basic science research, clinical epidemiology and health social science in relation to osteopathy and neuromusculoskeletal medicine.
The Editorial Board encourages submission of articles based on both quantitative and qualitative research designs. The Editorial Board also aims to provide a forum for discourse and debate on any aspect of osteopathy and neuromusculoskeletal medicine with the aim of critically evaluating existing practices in regard to the diagnosis, treatment and management of patients with neuromusculoskeletal disorders and somatic dysfunction. All manuscripts submitted to the IJOM are subject to a blinded review process. The categories currently available for publication include reports of original research, review papers, commentaries and articles related to clinical practice, including case reports. Further details can be found in the IJOM Instructions for Authors. Manuscripts are accepted for publication with the understanding that no substantial part has been, or will be published elsewhere.
