<br/><br/> Objective: To examine differences in hip flexibility before and after a 6-week muscle strengthening program between those with<br/>patellofemoral pain (PFP) and healthy controls.<br/>Design: Single-blind, multicentered, randomized controlled trial.<br/>Setting: Four clinical research laboratories.<br/>Subjects: Physically active individuals (199 PFP and 38 controls).<br/>Interventions: Patellofemoral pain and control subjects were randomized into either a hip-focused or a knee-focused muscle<br/>strengthening treatment program.<br/>Main Outcome Measures: Pain—visual analog scale (centimeter), function—Anterior Knee Pain Scale (points), flexibility—passive<br/>goniometry (degrees): hip adduction (HADD), hip external rotation (HER), hip internal rotation (HIR), total hip rotation (HROT), hip<br/>extension (HEXT) were measured before and after the muscle strengthening treatment program.<br/>Results: Subjects with patellofemoral pain who successfully completed the treatment program (n = 153) had 65%, 25%, 18%,<br/>and 12% less HADD, HER, HROT, and HIR ranges of motion (ROMs), respectively, than controls (P , 0.05). Patellofemoral pain<br/>subjects who did not successfully complete the program (n = 41) had 134%, 31%, 22%, and 13% less HADD, HER, HROT, and HIR<br/>ROMs, respectively, than controls (P , 0.05). All subjects increased their HIR, HROT, and HEXT ROMs pretest to posttest (P , 0.05),<br/>but by less than 2 degree.<br/>Conclusions: Individuals with PFP had less hip flexibility than controls regardless of treatment outcome or time. After the 6-week<br/>muscle strengthening program, and regardless of treatment success, PFP and control subjects experienced a small but clinically<br/>insignificant improvement in hip flexibility.<br/>Clinical Relevance: Hip ROM should be considered as a targeted area of focus in a rehabilitation program for physically active<br/>individuals with PFP
