OBJECTIVES: To determine the prevalence of myofascial trigger points (MTrPs) in
the gluteus medius (GMe) and quadratus lumborum (QL) for subjects with
patellofemoral pain (PFP), and to examine the relationship between MTrPs and
force production of the GMe after treatment. DESIGN: Randomized controlled trial.
SETTING: A physical therapy clinic. PARTICIPANTS: Subjects (N=52; mean age +/-
SD, 30+/-12y; mean height +/- SD, 172+/-10cm; mean mass +/- SD, 69+/-14kg)
volunteered and were divided into 2 groups: a PFP group (n=26) consisting of
subjects with PFP, and a control group (n=26) with no history of PFP.
INTERVENTIONS: Patients with PFP received trigger point pressure release therapy
(TPPRT). MAIN OUTCOME MEASURES: Hip abduction isometric strength and the presence
of MTrPs. RESULTS: Prevalence of bilateral GMe and QL MTrPs for the PFP group was
significantly higher compared with controls (P=.001). Subjects in the PFP group
displayed significantly less hip abduction strength compared with the control
group (P=.007). However, TPPRT did not result in increased force production.
CONCLUSIONS: Subjects with PFP have a higher prevalence of MTrPs in bilateral GMe
and QL muscles. They demonstrate less hip abduction strength compared with
controls, but the TPPRT did not result in an increase in hip abduction strength.
