肌肉本体感觉的缺失，无论是在节段还是在中枢水平，都会以几种方式损害性能。本体感觉对运动控制和学习的贡献不容易与其他感官信息来源（例如，视觉）。因此，罕见的广泛性神经病的临床病例，大规模和永久性地剥夺了大脑从皮肤和肌肉获得动力信息的主要来源，是非常特别的兴趣。两个这样的患者和控制进行了测试，在实验中调查（i）力的生产，（ii）幅度编码，（iii）空间参考框架指向，（iv）棱镜适应。总的来说，我们的研究结果突出了本体感受传入校准空间运动参照系的关键作用，以及中枢神经系统的强大替代特性。
The absence of muscular proprioception, whether at a segmental or at a central level, impairs performance in several ways. The contribution of proprioception to movement control and learning is not easily dissociated from that of other sources of sensory information (e.g., vision). Therefore, the rare clinical cases of extensive neuropathy, depriving the brain massively and permanently of its presumed main sources of dynamogenic information from skin and muscles, are of very special interest. Two such patients and controls were tested in experiments investigating (i) force production, (ii) amplitude coding, (iii) spatial reference frames in pointing, and (iv) prismatic adaptation. Overall, our results highlight the key role of proprioceptive afferents for calibrating the spatial motor frame of reference, and the powerful substitutive properties of the central nervous system.
