The objective of this study was to determine the prevalence of phantom pain and correlated conditions such as phantom sensations and stump pain in a population of cancer patients who had undergone limb amputation.
A cross-sectional study was carried out in adult patients submitted to limb amputation, who were being followed up at the Physiotherapy Department between April 3 and November 30, 2006. The presence of phantom pain and associated conditions was quantified using a verbal numerical scale. The data obtained were analyzed for means, medians, and proportions with their respective confidence intervals, as appropriate.
Seventy-five patients participated in this study, 50 men (66.7%) and 25 women (33.3%). Mean age was 54.4 years (SD +/- 18.5); range 19 to 88 years. The prevalence of phantom pain was 46.7% (95%CI: 35.1 to 58.6), phantom sensation 90.7% (95%CI: 81.7 to 96.2), and surgical stump pain 32.0% (95%CI: 21.7 to 43.8).
Phantom pain and phantom sensations are highly prevalent among cancer patients. Further studies should be carried out to determine the main factors associated with their onset.
本研究旨在确定接受肢体截肢的癌症患者人群中幻肢痛及相关情况（如幻肢感觉和残肢痛）的发生率。
对 2006 年 4 月 3 日至 11 月 30 日在理疗科接受肢体截肢并接受随访的成年患者进行横断面研究。使用言语数字量表量化幻肢痛和相关情况的存在。根据需要对获得的数据进行均值、中位数和比例分析，并给出相应的置信区间。
共有 75 名患者参与了本研究，其中 50 名男性（66.7%）和 25 名女性（33.3%）。平均年龄为 54.4 岁（标准差 +/- 18.5）；范围 19 至 88 岁。幻肢痛的发生率为 46.7%（95%CI：35.1 至 58.6），幻肢感觉为 90.7%（95%CI：81.7 至 96.2），手术残肢痛为 32.0%（95%CI：21.7 至 43.8）。
癌症患者中幻肢痛和幻肢感觉非常普遍。应进一步开展研究，以确定与其发生相关的主要因素。
