Takeuchi N, Kuwabara T, Usuda S. Development and evaluation of a new measure for muscle tone of ankle plantar flexors: the Ankle Plantar Flexors Tone Scale.
To develop and evaluate the reliability and concurrent validity of a clinically feasible measure for muscle tone of the ankle plantar flexors.
Cross-sectional reliability and validity study of the Ankle Plantar Flexors Tone Scale.
Department of rehabilitation in a general hospital.
Patients (N=74) with cerebrovascular disease.
Not applicable.
Muscle tone of the ankle plantar flexors was measured using the Ankle Plantar Flexors Tone Scale, the Modified Ashworth Scale (MAS), quality of muscle reaction with the Modified Tardieu Scale, and passive resistive joint torque with a handheld dynamometer. Intrarater and interrater reliabilities were assessed using the Cohen kappa coefficient (kappa). Internal consistency was assessed using the Cronbach alpha (alpha). Concurrent validity was assessed with the Spearman rank correlation coefficient (rho).
The Ankle Plantar Flexors Tone Scale included 3 items: stretch reflex, middle range resistance, and final range resistance. Intrarater and interrater reliabilities and internal consistency of the Ankle Plantar Flexors Tone Scale showed moderate to excellent agreement (kappa=.63-.94; alpha=.81). Concurrent validity of the Ankle Plantar Flexors Tone Scale was low to very high among the 3 items of the Ankle Plantar Flexors Tone Scale and existing measures. The Spearman rank correlation coefficient showed high to very high correlation between stretch reflex and quality of muscle reaction as indices of the central component (rho=.85-.94). Middle range resistance and final range resistance as indices of the peripheral component had low to moderate correlation with passive resistive joint torque using a handheld dynamometer and MAS (rho=.44-.68).
The Ankle Plantar Flexors Tone Scale allows measurement of ankle plantar flexor tone in greater detail than existing subjective measures and provides a reliable and valid method for research and clinical use.

使用踝关节跖屈肌肌张力量表、改良 Ashworth 量表（MAS）、改良 Tardieu 量表评估肌肉反应质量和手持测力计评估被动阻力关节扭矩来测量踝关节跖屈肌的肌张力。采用 Cohen kappa 系数（kappa）评估内部一致性和内部一致性。采用 Spearman 等级相关系数（rho）评估同时效度。
踝关节跖屈肌肌张力量表包括 3 项：牵张反射、中间范围阻力和终末范围阻力。踝关节跖屈肌肌张力量表的内部一致性和内部一致性显示中度至高度一致（kappa=0.63-0.94；alpha=0.81）。在 3 项踝关节跖屈肌肌张力量表和现有测量指标中，踝关节跖屈肌肌张力量表的同时效度较低至非常高。Spearman 等级相关系数显示，牵张反射和肌肉反应质量作为中枢成分指标之间存在高度至非常高的相关性（rho=0.85-0.94）。中间范围阻力和终末范围阻力作为外周成分的指标与使用手持测力计和 MAS 测量的被动阻力关节扭矩之间存在低度至中度相关性（rho=0.44-0.68）。
踝关节跖屈肌肌张力量表可以比现有的主观测量方法更详细地测量踝关节跖屈肌的肌张力，为研究和临床应用提供了一种可靠有效的方法。
