能够测量在体内施加在肌腱上的力，从而测量肌肉对肌腱产生的力，为研究生理学、生物力学、骨科和神经科学等学科中的问题提供了独特的机会。到目前为止，肌腱负荷只能通过植入或连接到这些胶原结构的侵入性传感器来直接评估。这项研究表明，作用在肌腱上的力可以测量，在一个非侵入性的方式，从声波的传播分析。使用马的浅趾屈肌腱作为模型，它表明，超声波传播的速度沿着肌腱的主轴与施加到这个肌腱的力增加。此外，我们表明，这种速度测量可以进行，即使在皮肤覆盖肌腱的存在。为了在体内验证这种测量技术，将行走时在跟腱中获得的超声速度图与其他作者使用侵入式换能器报告的载荷图进行比较。(c)2005爱思唯尔有限公司保留所有权利。
The ability to measure the forces exerted in vivo on tendons and, consequently, the forces produced by muscles on tendons, offers a unique opportunity to investigate questions in disciplines as varied as physiology, biomechanics, orthopaedics and neuroscience. Until now, tendon loads could be assessed directly only by means of invasive sensors implanted within or attached to these collagenous structures. This study shows that the forces acting on tendons can be measured, in a non-invasive way, from the analysis of the propagation of an acoustic wave. Using the equine superficial digital flexor tendon as a model, it is demonstrated that the velocity of an ultrasonic wave propagating along the main axis of a tendon increases with the force applied to this tendon. Furthermore, we show that this velocity measurement can be performed even in the presence of skin overlying the tendon. To validate this measurement technique in vivo, the ultrasonic velocity plots obtained in the Achilles tendon at the walk were compared to the loads plots reported by other authors using invasive transducers.
