应变计和粘接技术的最新进展使人们能够记录活体动物的骨应变。这种应变是由钢筋束张力和承重引起的。外侧和内侧骨应变都记录在步行马的第三掌骨上。这些菌株通常分别为430 μ菌株和150 μ菌株，峰间。在行走过程中记录的伸肌总腱张力有时高达170 N。这两组读数是互相关的，并提出了一个理论来解释肌腱动作，承重和运动方面的骨应变记录的主要特征。对大、小应变片测量结果的比较表明，覆盖骨表面1mm2的应变片测量结果是有效的。
Recent advances in strain gauges and bonding techniques permit the recording of bone strain in the living animal. Such strain is caused by tendon tension and by weight bearing. Both lateral and medial bone strain are recorded from the third metacarpal bone of the walking horse. These strains are typically 430 μ strain and 150 μ strain respectively, peak to peak. The tension in the common extensor tendon, recorded during walking, is found to be up to 170 N on occasions. The two sets of readings are cross-correlated and a theory is presented to account for the major features of the bone strain recordings in terms of tendon action, weight bearing, and locomotion. Comparison of results from large and small foil resistance strain gauges indicates that gauges covering 1 mm2of bone surface give valid results.
