To compare the effectiveness of adding anteromedial versus posterolateral hip musculature strengthening to knee strengthening in women with patellofemoral pain (PFP).
Randomized controlled trial.
University physiotherapy clinic.
Fifty-two women with PFP were randomized to receive either anteromedial (AMHG) or posterolateral (PLHG) hip musculature strengthening.
The primary outcomes were pain intensity by the numeric pain rating scale and function by the Anterior Knee Pain Scale in six weeks. Secondary outcomes were pain and function at six months, global perceived effect at six weeks and six months, pain in step down, isometric torque of abductors, adductors and hip rotators measured with hand-held dynamometer, and dynamic knee valgus by step down in six weeks.
Both groups showed improvement in primary outcomes; however, no differences were found between groups in pain intensity and function in six weeks and the secondary outcomes. Group x time interaction found superior gains in abductor strength in the PLHG and increase in the strength of the adductors and internal rotators in AMHG.
There was no difference between the addition of anteromedial or posterolateral hip musculature strengthening to knee strengthening in improving pain and function in women with PFP.
比较在膝强化训练的基础上增加前内侧或后外侧髋关节肌肉强化对髌股疼痛（PFP）女性的疗效。
随机对照试验。
大学物理治疗诊所。
52 名 PFP 女性被随机分为前内侧（AMHG）或后外侧（PLHG）髋关节肌肉强化组。
主要结局指标为 6 周时数字疼痛评分法的疼痛强度和前膝痛量表的功能。次要结局指标为 6 个月时的疼痛和功能、6 周和 6 个月时的整体感知效果、下台阶时的疼痛、手持测力计测量的外展肌、内收肌和髋关节旋转肌的等长扭矩以及 6 周时下台阶时的动态膝外翻。
两组主要结局均有改善；然而，6 周时两组间疼痛强度和功能无差异，其他次要结局也无差异。组 x 时间交互作用发现 PLHG 组外展肌力量增加，AMHG 组内收肌和内旋肌力量增加。
在膝强化训练的基础上增加前内侧或后外侧髋关节肌肉强化对 PFP 女性疼痛和功能的改善无差异。
