摘要

本研究的目的是：1）加剧髌骨股骨痛（PFP）对膝关节动态外翻（DKV）的影响；2）髌骨股骨痛女性患者中加剧的 PFP 与 DKV 之间的关系。我们评估了在单腿深蹲（SLS）任务中无 PFJ 负荷（条件 1）和有 PFJ 负荷（条件 2）两种情况下的疼痛强度和 DKV。我们使用 MANOVA 检验来比较两种情况下的疼痛强度和 DKV 角度。结果 MANOVA 分析表明，PFJ 负荷后，疼痛强度（P < 0.000，η2 = 0.623）和 DKV 角度（P < 0.000，η2 = 0.544）显著增加，效应大小为中等。此外，还观察到疼痛强度增加与 DKV 角度（P < 0.000，r = 0.840）之间存在极好的正相关性。因此，稳定肌肉的激活减少，下肢在额平面的运动增加。

Relationship between exacerbating patellofemoral pain and dynamic knee valgus in females with patellofemoral pain after a patellofemoral joint loading protocol: A cross-sectional

Objective

The aim of the present study is to 1) the effect of exacerbating patellofemoral pain (PFP) on dynamic knee valgus (DKV) 2) the relationship between exacerbating PFP and DKV in females with patellofemoral pain.

Design

Cross-sectional study.

Methods

Sixty women with PFP were recruited from the orthopedic clinics. We evaluated pain intensity and DKV in two conditions without (condition 1) and with (condition 2) PFJ loading during the single-leg squat (SLS) task. The MANOVA test was used to compare pain intensity and DKV angle between the two conditions. Furthermore, the Pearson correlation was used to examine the correlation between pain intensity with DKV angle.

Results

The MANOVA analysis showed that pain intensity (P < 0.000, η2 = 0.623) and DKV angle (P < 0.000, η2 = 0.544) with a medium effect size significantly increased after PFJ loading. Furthermore, an excellent positive correlation was observed between an increase in pain intensity and DKV angle (P < 0.000, r = 0.840).

Conclusion

It seems that after the PFJ loading protocol and the subsequent pain exacerbation, the neuromuscular biomechanics of the lower limb are deficits. As a result, the stabilizing muscles activation decreases and increases the lower limb movement in the frontal plane.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
