Abstract:Objective To investigate the effect of gluteus and core muscles stability training in patients with patellofemoral pain syndrome (PFPS). Methods A total of 118 patients with PFPS who received treatment at Rehabilitation Department of Nanjing BenQ Medical Center and the Rehabilitation Department of General Hospital of Eastern Theater Command from April 2020 to April 2021 were divided into the observation group and the control group randomly (n=59, each). The patients in the control group received quadriceps femoris and peri-articular knee muscles training, and the patients in the observation group received gluteus and core muscles stability training. Both groups of patients were treated continuously for 3 months. Lysholm knee score scale(LKSS), visual analog score (VAS) and other indicators between the two groups before and after treatment were compared. Results Before treatment, there was no significant difference between the two groups in LKSS score, VAS score, maximum peak torque of knee extension and knee flexion and quality of life (P＞0.05). After one month and three months of treatment, the LKSS score, the maximum peak moment of knee extension and flexion and the quality of life of the patients in the two groups were significantly improved compared with those before treatment (P＜0.05), and the VAS score was significantly decreased compared with those before treatment (P＜0.05). All indexes in the observation group were significantly better than those in the control group at the first month of treatment (P＜0.01), and there was no statistical difference between the two groups at the third month of treatment (P＞0.05). Conclusion For patients with PFPS, quadriceps femoris, peri-articular knee muscles strength exercise and gluteus, core muscles stability exercise can achieve significant effect, and the latter has earlier effect, patients can choose appropriate rehabilitation treatment program according to their own conditions.
