Individuals with nonspecific chronic low back pain (NSCLBP) and central sensitization (CS) exhibit sensory hypersensitivity that may be related to pre-existing trait characteristics. Sensory profiles and trait anxiety-related characteristics have sensory sensitivity in common with CS.
The objectives of this study were 1) to observe the prevalence of 4 personality types and extreme scores of 4 trait sensory profiles in people with NSCLBP and predominant CS; and 2) to compare these between 2 subgroups based on high and low self-reported CS symptoms.
An international cross-sectional observational study was undertaken.
Adults (n = 165; mean age = 45 ± 12 standard deviation) were recruited from physiotherapy clinics across 3 countries and 2 continents.
The inclusion criteria were: NSCLBP, aged 18-64 years, with clinically identified predominant CS pain, without specific pathology. The outcome measures were: Central Sensitization Inventory (CSI), Adolescent/Adult Sensory Profile, State/Trait Anxiety Inventory, and Marlowe Crowne Social Desirability Scale. Descriptive and comparative statistics were used.
CSI scores ranged from 19-79 (mean = 50). There was a high prevalence of extreme 1) trait sensory hyper- and, unexpectedly, hyposensitivity profile scores (P < 0.001) and Defensive High Anxious personality type (P < 0.01) in the high-CSI (CSI>= 40; 78%) subgroup, and 2) trait sensory hyposensitivity profile scores (P < 0.01) and Repressor personality type (P < 0.01) in the low-CSI subgroup (CSI < 40; 22%).
Self-report measures only were used; limited demographics.
To our knowledge, these results are the first to demonstrate extreme trait sensory profiles and personality types in people with NSCLBP and predominant CS. A subgroup who reports low levels of CS symptoms may have a hyposensitive sensory profile and Repressor personality type. Further study is required to investigate the extent to which these trait characteristics may predict CS symptoms in people with NSCLBP.

患有非特异性慢性下腰痛（NSCLBP）和中枢敏化（CS）的个体表现出感觉过敏，这可能与预先存在的特质特征有关。感觉特征和特质焦虑相关特征与 CS 具有共同的感觉敏感性。
本研究的目的是 1）观察具有主要 CS 疼痛的 NSCLBP 患者中 4 种人格类型和 4 种特质感觉特征的极端分数的患病率；2）根据自我报告的 CS 症状的高低，将这些分数在 2 个亚组之间进行比较。
这是一项国际横断面观察性研究。
来自 3 个国家和 2 个大陆的物理治疗诊所招募了 165 名成年人（平均年龄=45±12 标准差）。
纳入标准为：NSCLBP，年龄 18-64 岁，临床诊断为主要 CS 疼痛，无特定病理。结果测量指标包括：中枢敏化量表（CSI）、青少年/成人感觉特征量表、状态/特质焦虑量表和马洛-克劳恩社会期望量表。使用描述性和比较性统计。
CSI 评分范围为 19-79（平均=50）。在高 CSI（CSI>=40；78%）亚组中，1）特质感觉超敏和出乎意料的低敏特征评分（P<0.001）和防御性高焦虑人格类型（P<0.01），以及 2）特质感觉低敏特征评分（P<0.01）和压抑人格类型（P<0.01）的发生率较高。而在低 CSI 亚组（CSI<40；22%）中，这些发生率较低。
仅使用自我报告的测量方法；人口统计学数据有限。
据我们所知，这些结果是首次在具有主要 CS 症状的 NSCLBP 患者中发现极端特质感觉特征和人格类型。报告 CS 症状水平较低的亚组可能具有低敏感觉特征和压抑人格类型。需要进一步研究以调查这些特质特征在 NSCLBP 患者的 CS 症状中的预测程度。
