This systematic review and synthesis aimed to describe the frequency and characteristics of knee extensor exercise prescriptions within patellofemoral pain (PFP) interventions and to assess the extent to which key training variables are reported. By doing so, it sought to inform and support more transparent and standardized reporting practices in exercise-based rehabilitation for individuals with PFP.
This systematic review was conducted following PRISMA guidelines. A literature search was performed in January 2024 across Web of Science, PubMed, Scopus, CINAHL, and SportDiscus. Studies were included if they investigated interventions incorporating knee extensor exercises for PFP.
Seventy-nine studies met the inclusion criteria. The most commonly prescribed exercises were the straight leg raise, squat, and open-chain knee extension, typically performed as three sets of ten repetitions with bodyweight resistance. However, key training variables such as range of motion and intensity were often inadequately reported, limiting reproducibility and clinical applicability.
Knee extensor training for PFP predominantly consists of low-load, moderate-volume exercises, differing from conventional strength training recommendations. The lack of detailed reporting on critical variables, such as intensity and range of motion, reduces the clarity and applicability of rehabilitation protocols. Standardized reporting and further research are needed to optimize exercise prescription for PFP management.
本系统综述与综合分析旨在描述髌股疼痛（PFP）干预措施中伸膝练习处方的频率和特征，并评估关键训练变量的报告程度。通过这样做，它试图为PFP患者基于运动的康复中更透明和标准化的报告实践提供信息并提供支持。
本系统综述按照PRISMA指南进行。2024年1月在科学网、PubMed、Scopus、CINAHL和SportDiscus上进行了文献检索。如果研究调查了针对PFP的包含伸膝练习的干预措施，则将其纳入。
79项研究符合纳入标准。最常规定的练习是直腿抬高、深蹲和开链伸膝，通常以三组，每组十次重复，采用自重阻力进行。然而，关键训练变量，如运动范围和强度，往往报告不足，限制了可重复性和临床适用性。
针对PFP的伸膝训练主要包括低负荷、中等量的练习，这与传统的力量训练建议不同。对强度和运动范围等关键变量缺乏详细报告，降低了康复方案的清晰度和适用性。需要标准化报告和进一步研究以优化PFP管理的运动处方。
