Isokinetic dynamometry testing is a safe and reliable method accepted as the "gold standard" in the evaluation of muscle strength in the open kinetic chain. Isokinetic hip examinations face problems in the standardization of the position of the equipment axis, in the individual being examined, and in the adjustment of the lever arm and in stabilization strategies for the patients during the tests. Identification of the methodologic procedures with best reproducibility is also needed.
To review the literature to evaluate the parameters used for the isokinetic evaluation of the hip flexor and extensor muscles and its reproducibility.
This is a systematic literature review of the Cochrane, LILACS, PEDro, PubMed, and SciELO databases. The inclusion criteria were articles on the evaluation of hip flexor and/or extensor muscular strength with an isokinetic dynamometer and articles that analyzed the ICC or Pearson's reproducibility. The information extracted was positioning of the patient; positioning of the dynamometer axis; positioning of the lever arm; angular speed; sample size, pathology; type of contraction; and ICC and Pearson's results.
204 articles were found, from which 14 were selected that evaluated hip flexor and extensor muscles, involving 550 individuals who were submitted to an isokinetic hip evaluation. Five articles obtained the best result in reproducibility and had their methodology analyzed.
To obtain better reproducibility of the isokinetic evaluation of the hip flexor and extensor muscles, the following recommendations must be followed: the individual must be positioned in the supine position and the dynamometer axis must be aligned with the greater trochanter of the femur. The positioning of the lever arm must be in the most distal region of the thigh possible. The angular speed used to analyze torque peak and muscle work was 60°/s, and to evaluate the muscle power it was 180°/s, with concentric and eccentric contractions being analyzed.
等速测力测试是一种安全可靠的方法，被公认为开放动力链中肌肉力量评估的“金标准”。等速髋关节检查在设备轴位置的标准化、被检查个体、杠杆臂的调整以及测试过程中患者的稳定策略方面都面临问题。还需要确定具有最佳可重复性的方法步骤。
回顾文献，评估用于髋关节屈肌和伸肌等速评估的参数及其可重复性。
这是对Cochrane、LILACS、PEDro、PubMed和SciELO数据库的系统文献综述。纳入标准为使用等速测力计评估髋关节屈肌和/或伸肌力量的文章，以及分析组内相关系数（ICC）或皮尔逊可重复性的文章。提取的信息包括患者体位、测力计轴的位置、杠杆臂的位置、角速度、样本量、病理情况、收缩类型以及ICC和皮尔逊的结果。
共找到204篇文章，从中筛选出14篇评估髋关节屈肌和伸肌的文章，涉及550名接受等速髋关节评估的个体。五篇文章在可重复性方面取得了最佳结果，并对其方法进行了分析。
为了使髋关节屈肌和伸肌等速评估具有更好的可重复性，必须遵循以下建议：个体必须仰卧位，测力计轴必须与股骨大转子对齐。杠杆臂的位置必须尽可能在大腿最远端区域。用于分析扭矩峰值和肌肉功的角速度为60°/秒，评估肌肉功率时为180°/秒，同时分析向心收缩和离心收缩。
