Purpose:This study examined the effect of the strengthening exercise and stretching exercise to decrease symptom patellofemoral pain syndrome (PFPS).
Methods:The Anterior Knee Pain Scale (AKPS) and Clark’s test performed for diagnosis of intrinsic PFPS among young adults. Selected thirty young adults subjects who aged 20~26 years participated in the study. Participants were randomly assigned to strengthening, stretching, or control groups. Strengthening group consisted of quadriceps, hamstring and iliotibia band training used elastic band. Stretching group consisted of quadriceps, hamstring and iliotibia band trainings used stretching exercises program. Participants received 50-minute individualized exercise sessions, 3 times a week for 6 weeks.
Results:The results were as follow: there were significantly difference stretching exercise group by all muscles on muscular strength test (p<.05). there were significantly difference both strengthening and stretching exercise group by all muscles on flexibility test (p<.05). There were significantly difference stretching exercise group by all muscles on step-down test (p<.05). There were significantly difference both strengthening and stretching exercise group by all muscles on visual analog scale (p<.05).
Conclusion:Results suggest important implications for exercise programs of PFPS that stretching exercise is more improved knee pain, functional performance, patella mobility than strengthening exercise.
