People with amputations may find cycling advantageous for exercise, transportation and rehabilitation. The reciprocal nature of stationary cycling also makes it a viable model for research in motor control because the body is supported by the saddle allowing the researcher to focus on the cyclic movement of the legs without the confounding variable of balance. The purpose of this article is to provide an overview of the cycling task in intact cyclists and relate this information to understanding the challenges faced by cyclists with transtibial amputations (CTA). Ongoing research into the biomechanics of CTAs will be summarized to expose the differences between intact and CTA cycling mechanics, asymmetries between limbs of CTAs as well as neuromuscular adaptation following amputation. The article will include recommendations for prosthetic design and modification of the bicycle to improve cycling performance for CTA at all experience levels.
截肢者可能会发现骑自行车在锻炼、出行和康复方面具有优势。固定自行车骑行的往复特性也使其成为运动控制研究的一个可行模型，因为身体由车座支撑，这使研究人员能够专注于腿部的周期性运动，而无需考虑平衡这一混杂变量。本文的目的是概述健全骑行者的骑行任务，并将这些信息与理解经胫截肢骑行者（CTA）所面临的挑战联系起来。将总结正在进行的关于CTA生物力学的研究，以揭示健全骑行者与CTA骑行力学之间的差异、CTA双下肢之间的不对称性以及截肢后的神经肌肉适应性。本文还将包括针对假肢设计以及自行车改装的建议，以提高各经验水平的CTA的骑行性能。
