Meta‐analyses showed no significant changes in strength for any of the interventions . •
BACKGROUND : The addition of hip strengthening to knee strengthening for persons with patellofemoral pain has the potential to optimize treatment effects .
OBJECTIVE : To examine the efficacy of hip strengthening , associated or not with knee strengthening , to increase strength , reduce pain , and improve activity in individuals with patellofemoral pain .
Posterolateral hip muscle strengthening versus quadriceps strengthening for patellofemoral pain: a comparative control trial.
OBJECTIVE To compare the efficacy of posterolateral hip muscle strengthening versus quadriceps strengthening in reducing pain and improving health status in persons with patellofemoral pain ( PFP ) . DESIGN Comparative control trial . SETTING Rehabilitation facility . PARTICIPANTS Persons with a diagnosis of PFP ( N=36 ; 18 men , 18 women ) . INTERVENTIONS Patients were alternately assigned to a posterolateral hip muscle strengthening group ( 9 men and 9 women ) or a quadriceps strengthening group ( 9 men and 9 women ) . The posterolateral hip muscle strengthening group performed hip abductor and external rotator strengthening exercises , whereas the quadriceps strengthening group performed quadriceps strengthening exercises ( 3 times a week for 8wk ) . MAIN OUTCOME MEASURES Pain ( visual analog scale [ VAS ] ) and health status ( Western Ontario McMaster Universities Osteoarthritis Index [ WOMAC ] ) were assessed at baseline , postintervention , and 6-month follow-up . RESULTS Significant improvements in VAS and WOMAC scores were observed in both groups from baseline to postintervention and baseline to 6-month follow-up ( P<.001 ) . Improvements in VAS and WOMAC scores in the posterolateral hip exercise group were superior to those in the quadriceps exercise group postintervention and at 6-month follow-up ( P<.05 ) . CONCLUSIONS Although both intervention programs result ed in decreased pain and improved function in persons with PFP , outcomes in the posterolateral hip exercise group were superior to the quadriceps exercise group . The superior outcomes obtained in the posterolateral hip exercise group were maintained 6 months postintervention
