Abstract:
Objective:To investigate the lower limb muscle strength characteristics in amateur runners with patellofemoral pain(PFP). Method:Thirty PFP amateur runners(20 males and 10 females)were recruited as the knee pain group,and 30 matched non-injured amateur runners were recruited as the non-knee pain group.The hip abductor strength,quadriceps strength,hamstring strength,hamstring/quadriceps ratio,and bilateral limb symmetry index were col-lected for all participants.Independent sample t-tests were used to compare the differences between the groups. Result:The hip abductor strength and bilateral limb symmetry index,quadriceps strength and bilateral limb symmetry index of male PFP amateur runners were significantly lower than those of the non-knee pain group,while the hamstring/quadriceps ratio was significantly higher than that of the non-knee pain group.The hip ab-ductor strength and bilateral limb symmetry index of female PFP amateur runners were significantly lower than those of the non-knee pain group. Conclusion:PFP amateur runners exhibit different lower limb muscle strength characteristics compared to non-knee pain runners,and the lower limb strength characteristics of male and female PFP amateur runners are not consistent.Therefore,functional and gender differences should be considered in the clinical treatment and rehabilitation training of PFP.
