Abstract
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 resulted 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.
