Hind limb kinematics were recorded in five horses at walk and trot using an opto-electronic CODA-3 system. Simultaneously, in vivo strain in the completely tendinous peroneus tertius muscle was registered by implanted mercury-in-silastic strain gauges. The origin-insertion length patterns of the peroneus tertius were calculated from raw kinematic data and from data corrected for the error caused by skin displacement, and compared with the directly measured strain. The strain patterns calculated from externally measured kinematic data appeared to be in accordance with the directly measured strain gauge data. However, a correction for skin displacement is an obligatory prerequisite to obtain reliable results. The amplitudes of strain did not exceed 3% and appeared to be of about the same magnitude at both walk and trot.
使用光电CODA - 3系统记录了5匹马在行走和小跑时的后肢运动学数据。同时，通过植入的硅橡胶汞应变计记录完全腱性的第三腓骨肌的体内应变。根据原始运动学数据以及校正了皮肤位移引起的误差的数据，计算出第三腓骨肌的起止点长度模式，并与直接测量的应变进行比较。从外部测量的运动学数据计算出的应变模式似乎与直接测量的应变计数据一致。然而，校正皮肤位移是获得可靠结果的必要前提。应变幅度不超过3%，在行走和小跑时似乎大小相同。
