Different perspectives are needed to understand the pathophysiology of burning mouth syndrome (BMS), including physiological and psychological standpoints. The significance of interoception in chronic pain has been suggested. However, few studies have investigated this relationship in BMS. Therefore, we examined the role of interoception in BMS.
This is a cross-sectional study. BMS patients (N = 64) participated in the study. We used interoceptive accuracy (IAc) based on the heartbeat counting task. Then, participants were divided into high and low IAc groups, and their scores on clinical assessment including pain and psychological evaluation were compared.
The Visual Analogue Scale scores indicating pain in low IAc patients, but not high IAc patients, were positively correlated with the Beck Depression Inventory-Second Edition (BDI-II) and the State-Trait Anxiety Inventory-State (STAI-S) Scores.
Interoception might play a role in the pathophysiology of BMS.
为了理解灼口综合征（BMS）的病理生理学，包括生理和心理观点，需要不同的视角。人们已经提出了内脏感知在慢性疼痛中的重要性。然而，很少有研究调查这种关系在 BMS 中的表现。因此，我们研究了内脏感知在 BMS 中的作用。
这是一项横断面研究。BMS 患者（N=64）参与了研究。我们使用基于心跳计数任务的内脏感知准确性（IAc）。然后，参与者被分为高 IAc 组和低 IAc 组，并比较了他们在临床评估（包括疼痛和心理评估）中的得分。
低 IAc 患者的疼痛视觉模拟量表评分与贝克抑郁量表第二版（BDI-II）和状态特质焦虑量表状态（STAI-S）评分呈正相关，而高 IAc 患者则没有。
内脏感知可能在 BMS 的病理生理学中发挥作用。
