Introducing the Imprecision Hypothesis in Chronic Pain

I'm so excited to share with you something I've recently come to learn about - the Imprecision Hypothesis in Chronic pain. A paper published in 2015 by Moseley & Vlaeyen explores associative learning and imprecise encoding of danger messages and provides insight into how these changes contribute to the development of chronic pain. It offers a different yet complementing hypothesis to that of central sensitisation in pain.

The Neuromatrix of pain overlaps with the functional neuroanatomy of sleep

The previous blog explored the research showing how the relationship between pain and sleep is bidirectional. What explains this two-way relationship? Many of the articles suggested it is due to the multiple functions of neurotransmitters. Curious to know more about the overlap in functional areas of the brain involved in sleep and pain, I decided to compare the regions of the brain involved in wake and sleep and the neuromatrix.

The pain of social disconnection

I came across an interesting article written by Associate Professor in Social Psychology, Naomi Eisenberger, who works in the Department of Psychology at the University of California in LA.  Naomi asks a single question which I feel is so applicable to clinical practice as a physiotherapist "Why is it that negative emotions have such a profound effect on our emotional wellbeing?" This blog summaries the key points I learnt from reading her paper "The pain of social disconnection: examining the shared neural underpinnings of physical and social pain". Using this article and an example of a runner' tibial stress fracture, I explore the overlap between social and physical pain, describe how the distress of social disconnection outweighed the physical pain of the injury and how we strategised ways to manage the injury together.
