Purpose To compare the hip strength (hip abductor, external rotator, and extensor) and lower extremity kinematics (frontal and transverse plane of hip
PurposeTocomparethehipstrength(hipabductor,externalrotator,andextensor)andlowerextremitykinematics(frontalandtransverseplaneofhipjoint)betweenfemalewithandwithoutpatellofemoralpain,andtoinvestigatetherelationshipbetweenhipstrengthandlowerextremitykinematicstoseeiftheseparameterscouldpredictthefunctionalactivity.
MethodsTwentyfemalesubjectswithpatellofemoralpain,and20matchedhealthycontrolsparticipated.Allsubjectsunderwentmusclestrengthtestingofhipmusclesbyhand-helddynamometer,andlowerextremitykinematicstestingduringfunctionalascendanddescendstairsbyFastrak.Thefunctionalactivitywasmeasuredbyanteriorkneepainscaleandascend/descendstairs.
ResultsFemalesubjectswithpatellofemoralpainshowedsignificantlydecreasedhipexternalrotatorandextensorstrength(P<.05),andlowerhipabductorstrength(P=.06)comparedtothematchedcontrolgroup.Theyalsodemonstratedmorehipadductionandinternalrotationduringfunctionalascendanddescendstairs(P<.01)comparedtothematchedcontrol.Thefunctionalactivityperformancewassignificantlydifferentbetweenpatientsandcontrols(P<.01).Therewasnorelationshipbetweenhipstrengthandlowerextremitykinematics(P>.05),andbetweenhipstrength,lowerextremitykinematics,andanteriorkneepainscale(P>.05).However,hipextensorstrengthwassignificantlyassociatedwithfunctionalactivity(r=-.34~-.39,P<.03).Thehipadductionangleduringupstairswascorrelatedwithascendstairsperformance(r=.53,P<.001),whilethehipinternalrotationangleduringdescendstairswascorrelatedwithdescendstairsperformance(r=.43,P=.005).Multipleregressionsshowedascendstairstime=5.99–0.04*hipextensorstrength+0.25*hipadductionangle;descendstairstime=3.25–0.04*hipextensorstrength+0.18*hipinternalrotationangle.
ConclusionYoungfemalesubjectswithpatellofemoralpaindemonstrateddecreasedhipexternalrotatorandextensorstrength,andshowedgreaterhipadductionandinternalrotationduringfunctionalascendanddescendstairscomparedtothehealthycontrols.Hipextensorstrength,hipadductionandinternalrotationanglewereassociatedwithascend/descendstairsoffunctionalactivity.文目次口委T-I致x-II中文摘要-III英文摘要-V目-i表目.-iiiD目-vi附件目-v
