Abstract

Objectives

To examine peak and cumulative patellofemoral joint force when adolescents with patellofemoral pain run in a traditional athletic shoe, compared with a flat, flexible shoe.

Design

Cross-sectional.

Participants

Twenty-six adolescents with patellofemoral pain ran on an instrumented treadmill in a traditional athletic shoe and a flat, flexible shoe.

Main outcome measures

Cumulative and peak patellofemoral joint forces, knee flexion angle, knee extension and ankle plantarflexion moments, cadence, stride length and pain were compared between footwear conditions using paired t-tests.

Results

Peak patellofemoral joint reaction force was 11 % (p < 0.001) lower while running in the flat, flexible shoe (mean ± SD 3.62 ± 1.01 N/kg), compared to the athletic shoe (4.09 ± 0.97 N/kg). Cumulative patellofemoral joint force was 15 % (p < 0.001) lower while running in the flat, flexible shoe (195.09 ± 75.97 Bw.s/km), compared to the athletic shoe (231.54 ± 87.95 Bw.s/km). Peak knee flexion angle (p < 0.001) and knee extension moment (p = 0.001) were also lower when running in the flat, flexible shoe. There was no difference in peak ankle plantarflexion moment, running cadence, stride length, or pain between conditions.

Conclusions

Flat, flexible shoes may be a suitable intervention to lower cumulative patellofemoral joint loads during running in adolescents with patellofemoral pain.

与传统运动鞋相比，患有髌骨疼痛的青少年穿着扁平、灵活的鞋子跑步时，髌骨关节负荷较低

目的观察青少年髌骨疼痛患者穿传统运动鞋跑步时髌骨关节力的峰值和累积情况，并与穿平型柔性跑鞋进行比较。参与者26名患有髌骨疼痛的青少年，穿着传统的运动鞋和一双扁平的柔性鞋，在带器械的跑步机上跑步。主要观察指标：采用配对t检验比较不同鞋履条件下的累积和峰值髌骨关节力、膝关节屈曲角度、膝关节伸展和踝关节屈曲力矩、节奏、步幅和疼痛。结果髌股关节反作用力为11% (p <；0.001)，与穿运动鞋（4.09±0.97 N/kg）相比，穿平底、柔性跑鞋（平均±SD 3.62±1.01 N/kg）更低（平均值±SD 3.62±1.01 N/kg）。累计髌股关节力为15% (p <；0.001)，与运动鞋（231.54±87.95 Bw.s/km）相比，穿柔性平底鞋跑步（195.09±75.97 Bw.s/km）要低。膝关节最大屈曲角(p <；0.001)和膝关节伸展力矩（p = 0.001）也更低，当跑在平的，灵活的鞋。在两种情况下，踝关节跖屈峰值时刻、跑步节奏、步幅或疼痛没有差异。结论平的、有弹性的鞋可能是降低青少年髌骨股痛患者跑步时髌骨股关节累积负荷的合适干预措施。

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.
