Abstract Objective To use the Compensation Eccentric Strength Training System on patients with Patello-femoral pain syndrome，and assess the influence of rehabilitation on strength training.Methods 20 athletes who met the entry criteria PFPS from Beijing sport university were randomly divided into experimental and control groups.The experimental group underwent six weeks of lower limb centrifugal strength training，twice a week，using compensation eccentric strength training system(CC03).Load intensity of the subject were 120% 12RM maximum amount of centripetal force，15/group with 2 for each group.Use the BTE Primus (RS) maximum radial centrifugal peak torque and peak torque maximum system test subjects before and after training.Using the SPECTRON IR infrared thermal imaging for medical diagnostic test systems，affected part of the knee and surrounding normal skin temperature difference.PFPS subjects were evaluated using KOOS，VAS ratings.Results The average centrifugal force and KOOS score after training from subjects in the experimental group were significantly improved compared with before training (P＜0.05).VAS score and suffering knees and surrounding normal skin temperature difference were significantly lower (P＜0.05).At the same time there was no clear data of the change in the control group subjects (P＞0.05).Comparing the experimental group and the control group after the experiment，we found VAS score and knee lesion compared with the surrounding normal skin temperature of the subjects in the experimental group difference with the control group decreased significantly，bilateral lower extremity average centrifugal force and KOOS score was significantly increased(P＜0.05).Conclusion The improvement of the centrifugal force of the lower limbs has a therapeutic effect on PFPS.
