This study describes the sensations and pain reported by persons with unilateral lower extremity amputations. Participants (n = 92) were recruited from two hospitals to complete the Prosthesis Evaluation Questionnaire which included questions about amputation related sensations and pain. Using a visual analog scale, participants reported the frequency, intensity, and bothersomeness of phantom limb, residual limb, and back pain and nonpainful phantom limb sensations. A survey of medication use for each category of sensations also was included. Statistical analyses revealed that nonpainful phantom limb sensations were common and more frequent than phantom limb pain. Residual limb pain and back pain were also common after amputation. Back pain surprisingly was rated as more bothersome than phantom limb pain or residual limb pain. Back pain was significantly more common in persons with above knee amputations. These results support the importance of looking at pain as a multidimensional rather than a unidimensional construct. They also suggest that back pain after lower extremity amputation may be an overlooked but very important pain problem warranting additional clinical attention and study.
本研究描述了单侧下肢截肢者报告的感觉和疼痛情况。从两家医院招募了92名参与者，以完成假肢评估问卷，该问卷包括有关截肢相关感觉和疼痛的问题。参与者使用视觉模拟量表报告幻肢、残肢和背痛以及无痛幻肢感觉的频率、强度和困扰程度。还包括对各类感觉药物使用情况的调查。统计分析显示，无痛幻肢感觉很常见，且比幻肢痛更频繁。截肢后残肢痛和背痛也很常见。令人惊讶的是，背痛被评为比幻肢痛或残肢痛更困扰人。背痛在膝上截肢者中明显更常见。这些结果支持将疼痛视为多维而非单维结构的重要性。它们还表明，下肢截肢后的背痛可能是一个被忽视但非常重要的疼痛问题，值得更多的临床关注和研究。
