For quantifying muscle strength in clinical and research practice, establishing the reliability of measurements, specifically to the procedures used, is essential for credible findings. The objective was to establish the reliability of isokinetic measurement of ankle plantar and dorsal flexors (PF/DF) and invertors and evertors (INV/EV) on an IsoMed 2000 dynamometer. Twenty healthy subjects (10 males, 10 females, mean age: 23.1 ± 3.1 years) completed an isokinetic measurement session. The intraclass correlation coefficient (ICC) and standard error of measurement were assessed for peak torque and work of ankle PF/DF (concentric and eccentric) and INV/EV (concentric) for the preferred and nonpreferred limb. Standardized isokinetic measurements of reciprocal PF/DF and INV/EV muscle actions were associated with ICC ranging from 0.77 to 0.98 for the majority of observed parameters. The exception was work in the eccentric mode in the ankle DF and peak torque in the concentric mode in the ankle INV on the preferred limb, where ICC ranged from 0.64 to 0.71. The IsoMed 2000 isokinetic dynamometer can be reliably employed in future studies for reciprocal ankle PF/DF and INV/EV assessment in healthy adult subjects after implementation of a familiarization session.
为了在临床和研究实践中量化肌肉力量，建立测量的可靠性，特别是对所使用的程序进行可靠性评估，对于可信的研究结果至关重要。本研究旨在评估 IsoMed 2000 等动测力仪测量踝关节跖屈和背屈（PF/DF）及内翻和外翻（INV/EV）肌群等速肌力的可靠性。20 名健康受试者（10 名男性，10 名女性，平均年龄：23.1±3.1 岁）完成了等速测量。对优势侧和非优势侧踝关节 PF/DF（向心和离心）和 INV/EV（向心）的峰值力矩和功进行了组内相关系数（ICC）和测量误差（SEM）评估。观察到的大多数参数的 ICC 范围为 0.77 至 0.98，标准化的踝关节 PF/DF 和 INV/EV 肌肉反向活动的等速测量结果与 ICC 相关。在优势侧踝关节 DF 的离心模式下的功和踝关节 INV 的向心模式下的峰值力矩，ICC 范围为 0.64 至 0.71。在实施熟悉化训练后，IsoMed 2000 等动测力仪可用于未来的健康成年受试者踝关节 PF/DF 和 INV/EV 评估的研究中。
