Pain Science in Practice: What Is Pain Neuroscience? Part 1

Spine Pain

OBJECTIVE

Spine pain is one of the most common presenting concerns in health care settings. This article reviews clinical strategies for evaluating and managing patients with spine pain.

LATEST DEVELOPMENTS

Minimally invasive interventional procedures, virtual reality, predictive analytics, neuromodulation, and other evolving technologies are significantly impacting the management of spine pain. Advances in modern pain science have also led to effective skills and treatment strategies, including patient interviews and queries for insight regarding pain, education, and cognitive restructuring, and adjusting the timing of examination (after reeducation) and examination techniques to encourage the experience of movement in the absence of assumed tissue damage. An evolving understanding of the influence of patient-centric thoughts, framing, emotional status, and cognitive restructuring's influence on the brain's response to perceived threat are important aspects of spine pain management.

ESSENTIAL POINTS

The correlation of clinical presentations with structural abnormalities is necessary but insufficient to evaluate and manage spine pain. Modern pain science acknowledges pain as a subjective experience but recognizes a critical distinction between tissue damage, nociception, and the experience of pain. What and how we communicate with patients, as well as evolving neuromodulation technologies, augment conventional approaches.

Altered somatosensory functioning and mechanism-based classification in breast cancer patients with persistent pain

Pain is one of the most frequent and persistent side effects of breast cancer treatment. Besides pain, breast cancer survivors (BCS) are prone to experience a myriad of other signs and symptoms related to altered somatosensory function, including for example, hypoesthesia, allodynia, and hyperalgesia, both at the local site of cancer and in remote body parts. Different breast cancer treatments can have a direct effect on somatosensory functioning, resulting in a wide range of these signs and symptoms. To our knowledge, currently no comprehensive overview exists on altered somatosensory functioning and resulting signs and symptoms in BCS with persistent pain. Investigating altered somatosensory functioning in this population could provide more insights in the underpinning pathophysiological mechanisms and consequently improve prevention and treatment in the future. Therefore, in this paper, first, normal somatosensory functioning is described. Second, quantitative sensory testing is presented as the recommend method to evaluate somatosensory functioning. Third, existing evidence on altered somatosensory functioning in BCS with persistent pain is summarized. Altered somatosensory functioning related to the most common cancer treatment modalities, including surgery and radiotherapy, hormone therapy, and chemotherapy are discussed. In addition, evidence on the presence of nociplastic pain as pain resulting from altered somatosensory functioning without evidence for nociception and/or neuropathy in BCS is summarized. At last, a discussion on this available evidence, limitations, and perspectives for clinical practice and for research are made.
