چکیده | ||
Patellofemoral pain syndrome (PFPS) is one of the anatomical abnormalities and one of the most common knee problems, which causes anterior knee pain. Vastus medialis oblique (VMO) weakness and contracture of plantar flexors are among the most important factors to cause this syndrome. The purpose of the present study was to investigate the effect of concurrent planter flexor stretching and VMO strengthening in females with PFPS. 30 females (age 38.4±3.48 years, weight 70.5±2.89 kg) with PFPS participated in this study. Participants were randomly assigned to control and experimental groups. Experimental group received common medical treatment in addition to eight weeks of concurrent plantar flexor stretching and VMO strengthening exercises, while control group received only common medical treatment. The WOMAC questionnaire was administered to assess pain, physical dysfunction and stiffness. Also, range of motion of dorsiflexion, knee extension and Q angle were measured before and after the treatment. ANOVA with repeated measures was administered to analyze the data (P<0.05). The results after eight weeks of treatment showed a significant decrease in WOMAC score in both groups (compared to pretest) while the experimental group showed greater improvement. In the experimental group, range of motion of dorsiflexion increased significantly after eight weeks (P<0.05) (compared to pretest and control group). Also, Q angle decreased significantly in both groups (compared to pretest). Range of motion of knee extension increased significantly in both groups (compared to pretest) while experimental group gained more range of motion than control group. It can be concluded that concurrent planter flexor stretching and VMO strengthening may increase the efficiency of treatment of patients with PFPS. | ||
