Poor Pain Outcomes After Musculoskeletal Surgery Can Be Predicted By Post-Injury Anxiety and PTSD

New clinical research from UTCSP members Dr. Colin McCartney and Dr. Joel Katz, and PhD candidate Brittany Rosenbloom helps to shed light on the vulnerabilities in patients that may predispose them to have poor pain outcomes, including development of chronic neuropathic pain.

Cognitive Behavioural Training for Pain: Does it Change your Brain?

UTCSP member Dr. Karen Davis and her colleagues, Drs. Aaron Kucyi and Tim Salomons, recently reported in PAIN on differences in the brain function of healthy individuals via fMRI before and after cognitive behavioural training and repeated painful heat stimulus application.

Neural Mechanisms Underlying Anxiety-Chronic Pain Interactions

In a recent article in Trends in Neuroscience, Dr. Min Zhuo discusses the link between anxiety and chronic pain. While chronic pain and anxiety are often comorbid, and treating anxiety can result in a reduction in pain, these conditions are usually studied separately. Dr. Zhuo proposes that these conditions are related via long-term potentiation (LTP) mechanisms in the anterior cingulate cortex (ACC).

The Periaqueductal Gray Matter: Sub-regions and Functional Connectivity with Descending Pain Modulation Circuitry

The experience of pain is highly variable between individuals for a multitude of physiological and psychological reasons. Evidence now suggests that part of this variability is due to interactions between ascending nociceptive signaling pathways and descending modulatory circuitry. The periaqueductal gray matter (PAG) is a critical brain region involved in top-down modulatory circuits. The laboratory of Dr. Karen Davis, and post-doctoral fellow Dr. Marie-Andree Colulombe recently investigated sub-regions of the PAG and their functional connectivity with other brain regions involved in pain processing.

Longitudinal Study of Catastrophizing, Pain and Cortical Thickness in Chronic Pain Patients

Neuropathic pain is a common chronic pain condition, which occurs following peripheral nerve injury (PNI). It is currently unknown why only some individuals with PNI develop chronic pain. However, it is predicted that both biological and psychological factors contribute to this process. The laboratory of Dr. Karen Davis recently conducted a longitudinal investigation of pan catastrophizing (i.e., when an individual has exaggerated negative thinking about painful experiences) and insula gray matter changes in patients with nerve injury.

Abnormal cross-network functional connectivity in chronic pain and its association with clinical symptoms

Kasey Hemington, Keith Wu, Aaron Kucyi, Robert Inman and Karen Davis recently published a neuroimaging study, characterizing abnormalities between functional brain networks in chronic pain patients. The authors used resting state, functional magnetic resonance imaging to uncover abnormal connections between functional networks that were closely related to clinical symptom severity.
