Phantom sensations, that is, sensations perceived in a body part that has been lost, are a common consequence of accidental or clinical extremity amputations. Most amputation patients report a continuing presence of the limb, with some describing additional sensations such as numbness, tickling, or cramping of the phantom limb. The type, frequency, and stability of these phantom sensations can vary immensely. The phenomenon of painful phantom sensations, that is, phantom limb pain, presents a challenge for practitioners and researchers and is often detrimental to the patient's quality of life. In addition to the use of conventional therapies for chronic pain disorders, recent years have seen the development of novel treatments for phantom limb pain, based on an increasing body of research on neurophysiological changes after amputation. This article describes the current state of research in regard to the demographics, causal factors, and treatments of phantom limb pain.
幻肢感觉，即感觉到已失去的身体部位存在感觉，是意外或临床肢体截肢的常见后果。大多数截肢患者报告称失去的肢体仍然存在，有些人还描述了幻肢的其他感觉，如麻木、瘙痒或抽筋。这些幻肢感觉的类型、频率和稳定性差异极大。疼痛性幻肢感觉现象，即幻肢痛，给从业者和研究人员带来了挑战，并且常常对患者的生活质量有害。除了使用针对慢性疼痛疾病的传统疗法外，近年来，基于对截肢后神经生理变化的越来越多的研究，已经开发出了针对幻肢痛的新疗法。本文描述了关于幻肢痛的人口统计学、病因和治疗方面的当前研究状况。
