项目摘要
PROJECT SUMMARY:
Chronic pain is a complex, medically unexplained disorder that poses enormous burden to both the patient and
the healthcare system. In the face of the opioid epidemic, the need for better scientific understanding of the
neuro- and psycho-biological underpinnings of chronic pain to guide improved treatment approaches is clear.
Non-pharmacological interventions, including contemplative and integrative practices, have shown efficacy in
improving pain and bolster efforts to reduce opioid-ergic medical management. These interventions often target
the processing of internal painful and non-painful sensory signals, referred to as interoception. Neural processing
of interoceptive stimuli overlaps with many of the regions altered in chronic pain, and self-report interoceptive
questionnaires and tasks show diminished interoceptive performance in pain patients. However, the translational
relevance of interoceptive functioning in pain treatment trajectories has been hindered by the lack of clear tasks
and questionnaire measures of interoception.
The overall objective of this proposal is to establish whether neural processing of non-painful interoceptive
stimuli, namely the heartbeat, is altered in chronic low back pain patients at various stages of treatment and
predictive of non-response to invasive peripherally-targeted treatments compared to healthy adults. This NRSA
project will identify how electrophysiological dynamics (EEG/ECG) are related to interoceptive processes and
pain treatment response using two newly developed, validated, and rigorously controlled interoception tasks that
assess neural responses to the heart (Heartbeat-Evoked Potential, HEP). I will systematically test the
hypothesis that chronic pain patients will display diminished modulation of the HEP during attention to
their heartbeat compared to healthy controls (Aim 1) and impaired interoceptive-exteroceptive
integration when an exteroceptive tone previously synchronized with the heartbeat is unexpectedly
omitted (Aim 2). I will also test that these measures at baseline can predict non-response to pain
intervention. Together, these data will establish whether neural markers of non-painful interoceptive processing
could be clinically relevant biomarkers for guiding treatment selection in chronic low back pain, and would have
broad implications for the incorporation of behavioral interventions targeting interoceptive processing. In
preparation for this NRSA, I have sought out mentors who have expertise in interoceptive tasks,
electrophysiology (EEG and ECG) data acquisition, analysis and interpretation, clinical interventional pain
management, and complementary and integrative pain care. This proposal was designed to give me the training
needed for a future profession as a Pain Management physician conducting research on interoceptive dynamics
in chronic pain, and their relation to healing with integrative medicine modalities.

慢性疼痛是一种复杂的、医学上无法解释的疾病,给患者和患者都带来巨大的负担。
医疗保健系统。面对阿片类药物的流行,需要对阿片类药物有更好的科学认识
指导改善治疗方法的慢性疼痛的神经和心理生物学基础是明确的。
非药物干预措施,包括沉思和综合实践,已在以下方面显示出功效:
改善疼痛并加强努力减少阿片类药物的医疗管理。这些干预措施通常针对
内部疼痛和非疼痛感觉信号的处理,称为内感受。神经处理
内感受刺激与慢性疼痛改变的许多区域重叠,并且自我报告内感受

该提案的总体目标是确定非疼痛内感受的神经处理是否
慢性腰痛患者在治疗的各个阶段都会改变刺激,即心跳。
