To evaluate interoceptive accuracy (Iac) before and after a single yoga class in a population of patients with anorexia nervosa (AN) and in a population of healthy controls (HC).
Fifteen patients with AN and twenty HC were included in the study. All individuals participated in a single yoga class. Before (T0) and after (T1) the yoga class, they underwent the heartbeat detection task for the evaluation of Iac. At T0, all participants also underwent a psychological assessment, including evaluation of depression, anxiety, body awareness, alexithymia, self-objectification and eating disorders psychopathology.
Patients with AN had lower Iac than HC at T0. A significant improvement of Iac at T1 was found in the HC group but not in the group of patients with AN.
We infer that our findings might be linked to the fact that patients with AN, differently from HC, did not properly attend to their bodies, despite the yoga class. This hypothesis is consistent with previous studies showing that patients with AN have decreased Iac during self-focused behavior because of body-related avoidance. Moreover, we surmise that HC might be keener to improve their perception of internal body signals even after a single yoga class because their emotional awareness system is not impaired. Patients with AN, on the contrary, may have an intrinsic impairment of their emotional awareness, making it harder for them to modulate their Iac.
Level III, evidence obtained from well-designed cohort or case-control analytical studies.
评估厌食症 (AN) 患者和健康对照组 (HC) 人群单次瑜伽课后的内脏感觉准确性 (Iac)。
本研究纳入了 15 名 AN 患者和 20 名 HC。所有个体均参加了单次瑜伽课。在瑜伽课前 (T0) 和课后 (T1)，他们接受了心跳检测任务以评估 Iac。在 T0 时，所有参与者还接受了心理评估，包括抑郁、焦虑、身体意识、述情障碍、自我客体化和饮食障碍心理病理学的评估。
在 T0 时，AN 患者的 Iac 低于 HC。在 HC 组中发现 T1 时 Iac 显著改善，但在 AN 患者组中未发现。
我们推断，我们的发现可能与以下事实有关，即与 HC 不同，AN 患者尽管参加了瑜伽课，但并没有正确关注自己的身体。这一假设与之前的研究一致，即 AN 患者在进行自我关注行为时 Iac 降低，这是由于身体相关的回避。此外，我们推测 HC 可能更热衷于在单次瑜伽课后改善他们对内部身体信号的感知，因为他们的情绪意识系统没有受损。相反，AN 患者可能对他们的情绪意识有内在的损害，这使得他们更难调节他们的 Iac。
III 级，来自精心设计的队列或病例对照分析研究的证据。
