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 .
The effect of additional strengthening of hip abductor and lateral rotator muscles in patellofemoral pain syndrome: a randomized controlled pilot study
Objectives : To study the effect of additional strengthening of hip abductor and lateral rotator muscles in a strengthening quadriceps exercise rehabilitation programme for patients with the patellofemoral pain syndrome . Design : R and omized controlled pilot trial . Setting : Clinical setting with home programme . Participants : Fourteen patients with patellofemoral pain syndrome . Intervention : The subjects were r and omly assigned to the intervention group ( strengthening of quadriceps plus strengthening of hip abductor and lateral rotator muscles ) or to the control group ( strengthening of quadriceps ) . Both groups participated in a six-week home exercise protocol . Main outcome measures : The perceived pain symptoms , isokinetic eccentric knee extensor , hip abductor and lateral rotator torques and the gluteus medius electromyographic activity were assessed before and after treatment . Parametric and non-parametric tests were used to compare the groups before and after treatment with α=0.05 . Results : Only the intervention group improved perceived pain symptoms during functional activities ( P=0.02—0.04 ) and also increased their gluteus medius electromyographic activity during isometric voluntary contraction ( P=0.03 ) . Eccentric knee extensors torque increased in both groups ( P=0.04 and P=0.02 ) . There was no statistically significant difference in the hip muscles torque in either group . Conclusion : Supplementation of strengthening of hip abductor and lateral rotator muscles in a strengthening quadriceps exercise programme provided additional benefits with respect to the perceived pain symptoms during functional activities in patients with patellofemoral pain syndrome after six weeks of treatment
