Abstract：
UNASSIGNED: To validate a novel technique to measure limb stiffness in a clinical setting.
UNASSIGNED: Three horses and three ponies owned by the Royal Veterinary College.
UNASSIGNED: Limb stiffness indices for both forelimbs were first derived using the gold standard of kinematic analysis. Using the same animals, limb stiffness indices were then calculated using portable floor scales to record weight and an electrogoniometer to record changes in metacarpophalangeal joint angle. The two techniques were then assessed for correlation and repeatability.
UNASSIGNED: The repeatability of limb stiffness measurement using the novel clinical tool was considered to be good based on a small coefficient of variation (5.70%). The correlation of limb stiffness as derived by both methods was high (r = 0.78, p < 0.01). Limb stiffness was positively correlated with the mass of the subject (r = 0.85, p < 0.01), with heavier horses having greater limb stiffness.
UNASSIGNED: This study has compared a novel method to measure distal forelimb stiffness non-invasively in a clinical setting to kinematic analysis in six equids. It has demonstrated that limb stiffness increases in a linear fashion with body mass consistent with the role of forelimbs providing energy storage. Because in vivo limb stiffness has been shown previously to alter with injury to the superficial digital flexor tendon, it is hypothesized that this technique will offer a practical technique for the clinician to assess limb stiffness in clinical cases. Further study will be necessary to determine its clinical usefulness in such cases.

摘要：
■验证一种在临床环境中测量肢体僵硬度的新技术。
■皇家兽医学院拥有三匹马和三匹小马。
■首先使用运动学分析的黄金标准得出两个前肢的肢体刚度指数。使用相同的动物，然后使用便携式地板秤记录体重并使用测角仪记录掌指关节角度的变化来计算肢体刚度指数。然后评估这两种技术的相关性和可重复性。
■基于较小的变异系数（5.70％），使用新型临床工具进行肢体僵硬测量的可重复性被认为是良好的。两种方法得出的肢体僵硬的相关性很高（r=0.78，p<0.01）。肢体僵硬度与受试者的体重呈正相关(r=0.85,p<0.01),较重的马有更大的四肢僵硬。
■这项研究将一种在临床环境下非侵入性测量远端前肢刚度的新颖方法与六只马的运动学分析进行了比较。已经证明,肢体刚度以线性方式增加,身体质量与前肢提供能量存储的作用一致。因为以前已经证明体内肢体僵硬会随着浅表指屈肌腱的损伤而改变，据推测，这项技术将为临床医生在临床病例中评估肢体僵硬提供一种实用的技术。需要进一步研究以确定其在这种情况下的临床实用性。
