Previous studies have estimated that between 25% and 45% of people with spinal cord injury report severe levels of chronic pain. Few studies have examined this longitudinally. This study examines the primary pain sites, intensity and variability of perceived pain in 76 patients, 6 weeks post injury and 45 patients from the same cohort, 8 year post discharge. Demographic information reveals a close similarity with the database (40,000) from Stover and Fine's cohort (1986). Data was assessed using visual analogue scales, measures were also taken of functional independence (FIM), emotional status and coping. At 6 weeks post injury, most pain is sited in the thoracic spine area, and in the upper and lower limbs. At 1 year post discharge, most pain is reported to be in the thoracic spine area, the lumbar region and the chest. Twenty-three per cent of the 6 week group reported that the intensity of their pain was severe, whilst at 1 year, 41% of the sample complained of severe pain. Factors associated with the pain at both time points were explored using correlational analyses. The emotional, functional and psychological factors that predict pain severity were explored using multiple regression analysis. Twenty-four per cent of those reporting moderate to severe pain at 6 weeks post injury were still reporting pain at 1 year post discharge. This study examines the relative contribution of psychological factors in reported pain.
以往研究估计，25%至45%的脊髓损伤患者报告有严重程度的慢性疼痛。很少有研究对此进行纵向研究。本研究调查了76例患者受伤6周后以及同一队列中45例患者出院8年后的主要疼痛部位、疼痛强度及疼痛感知的变异性。人口统计学信息显示与Stover和Fine队列（1986年）的数据库（40000例）极为相似。使用视觉模拟量表评估数据，还对功能独立性（FIM）、情绪状态和应对方式进行了测量。受伤6周后，大多数疼痛位于胸椎区域以及上肢和下肢。出院1年后，大多数疼痛报告位于胸椎区域、腰椎区域和胸部。6周组中有23%的患者报告其疼痛强度严重，而在1年后，41%的样本抱怨有严重疼痛。使用相关性分析探究了两个时间点与疼痛相关的因素。使用多元回归分析探究了预测疼痛严重程度的情绪、功能和心理因素。受伤6周后报告有中度至重度疼痛的患者中，有24%在出院1年后仍报告有疼痛。本研究调查了心理因素在报告疼痛中的相对作用。
