The aim of this study was to increase our understanding of the role that spatial qualities of pain (location and extent) play in functioning, among youths with disabilities and chronic pain.
One-hundred and fifteen youths (mean age 14.4 years; SD ±3.3 years) with physical disabilities and chronic pain were interviewed and were asked to provide information about pain locations and their average pain intensity in the past week, and to complete measures of pain interference, psychological function and disability. Most of the participants in this sample were males (56%), Caucasian (68%), and had a cerebral palsy (34%) or muscular dystrophy (25%) problem. Most participants did not report high levels of disability ( [Formula: see text], SD ±9.5, range 0-60) or global pain intensity ( [Formula: see text], SD ±2.4, range 0-10).
Pain at more than one body site was experienced by 91% of participants. There were positive associations between pain extent with pain interference ( = 0.30) and disability ( = 0.30), and a negative association with psychological function ( = -0.38), over and above average pain intensity. Additionally, pain intensity in the back (as opposed to other locations) was associated with more pain interference ( = 0.29), whereas pain intensity in the shoulders was associated with less psychological function ( = -0.18), and pain intensity in the bottom or hips was associated with more disability ( = 0.29).
The findings support the need to take into account pain extent in the assessment and treatment of youths with physical disabilities and chronic pain, call our attention about the need to identify potential risk factors of pain extent, and develop and evaluate the benefits of treatments that could reduce pain extent and target pain at specific sites.
本研究旨在加深我们对疼痛的空间特征（位置和范围）在残疾及慢性疼痛青少年的功能中所起作用的理解。
对115名患有身体残疾和慢性疼痛的青少年（平均年龄14.4岁；标准差±3.3岁）进行了访谈，要求他们提供过去一周内疼痛位置及其平均疼痛强度的信息，并完成疼痛干扰、心理功能和残疾程度的测量。该样本中的大多数参与者为男性（56%），白种人（68%），患有脑瘫（34%）或肌肉萎缩症（25%）。大多数参与者未报告高水平的残疾（[公式：见正文]，标准差±9.5，范围0 - 60）或总体疼痛强度（[公式：见正文]，标准差±2.4，范围0 - 10）。
91%的参与者经历过身体多个部位的疼痛。除平均疼痛强度外，疼痛范围与疼痛干扰（= 0.30）和残疾程度（= 0.30）呈正相关，与心理功能呈负相关（= -0.38）。此外，背部的疼痛强度（与其他部位相比）与更多的疼痛干扰相关（= 0.29），而肩部的疼痛强度与较低的心理功能相关（= -0.18），臀部或髋部的疼痛强度与更多的残疾相关（= 0.29）。
研究结果支持在评估和治疗身体残疾及慢性疼痛青少年时需考虑疼痛范围，提醒我们需要识别疼痛范围的潜在风险因素，并开发和评估可减少疼痛范围并针对特定部位疼痛的治疗方法的益处。
