The primary objective of this study is to compare the prevalence of phantom limb pain in New Zealand and Cambodian amputees and to assess the demographics of a sample of amputees from these two countries.
All participants were interviewed using a 12-question survey that covered demographic data and reason for amputation and assessed the presence of phantom limb sensation, phantom limb pain, and stump pain. Amputees attending an artificial limb center in Cambodia were approached and interviewed in person. New Zealand amputees attending the Waikato artificial limb center were randomly selected and interviewed by phone.
There was no statistically significant difference in phantom limb sensation, phantom limb pain, or stump pain between the two groups. There was a much higher unemployment rate in the Cambodian amputees. There were no other statistically significant differences between the groups
Despite very different environments, there was no difference in the phantom limb pain between the groups. One possible explanation is that the severity of neurological injury associated with amputation overrides all the other risk factors that influence the development of other chronic pain syndromes.
本研究的主要目的是比较新西兰和柬埔寨截肢者的幻肢痛患病率，并评估来自这两个国家的截肢者样本的人口统计学特征。
所有参与者均接受了一项包含人口统计学数据和截肢原因的 12 个问题的调查，以评估幻肢感觉、幻肢痛和残肢痛的存在。在柬埔寨的一家假肢中心，对前来就诊的截肢者进行了面谈。在新西兰，Waikato 假肢中心随机选择并通过电话对前来就诊的截肢者进行了访谈。
两组之间的幻肢感觉、幻肢痛或残肢痛无统计学显著差异。柬埔寨截肢者的失业率高得多。两组之间没有其他统计学显著差异。
尽管环境非常不同，但两组之间的幻肢痛没有差异。一种可能的解释是，与截肢相关的神经损伤的严重程度超过了影响其他慢性疼痛综合征发展的所有其他风险因素。
