The influence of psychosocial stress, gender, and personality on mechanical loading of the lumbar spine
Review by Courtney Zoschke
In recent years, the cause of low back pain disorders in the workplace has been actively debated. Prior research has focused primarily on identifying physical characteristics of the workplace that may influence biomechanics and spinal loading and subsequent injury risk. Little work, however, has been done to assess how psychosocial stress may affect muscle activity and spinal loading. This study sought to investigate the impact of psychological stress on variables that influence spinal loading while controlling for biomechanical effects. The study also aimed to identify particular personality traits as a predictor for low back pain under psychosocial stressors.

Expectancies Mediate the Relations Among Pain Catastrophizing, Fear of Movement, and Return to Work Outcomes After Whiplash Injury
Review by Yasmin Khaliki
A great number of patients at our clinic suffer from whiplash-associated disorders following motor vehicle accidents that take away from their quality of life, comfort, and at times cause them to take prolonged time off work. Fear of movement and pain catastrophizing have proven to extend that duration of time that it takes for an individual to return to work post injury. The avoidance of movement based on fear and the exaggerated negative response to an unpleasant experience have been shown to result in greater disability for individuals suffering from whiplash, as well as many other injuries.

Predictors of persistent pain after breast cancer surgery: a systematic review and meta-analysis of observational studies
Review by Curtis May
Despite the increased longevity breast cancer surgery provides patients, 25-60% of patients are expected to experience persistent post-surgical pain. An updated systematic review of the evidence was done to identify the main predictors of developing chronic pain following breast cancer surgery and then how to reduce this risk.

Pain Acceptance Decouples the Momentary Associations Between Pain, Pain Interference, and Physical Activity in the Daily Lives of People with Chronic Pain and Spinal Cord Injury:
Review by Gurjeet Bhangu
Chronic pain acceptance is an important predictor of adjustment to pain. Preliminary evidence has illustrated that pain acceptance breaks the links between pain and emotional distress. However, no known research has investigated whether pain acceptance can decouple the connection between pain intensity and general pain interference or physical activity. This review is on an article published in The Journal of Pain which examines the significance of pain acceptance in the context of chronic pain.

The role of the microbiome in human health and disease: an introduction for clinicians
Review by Dr. Lindsay Rite
While gut health has been a long standing pillar at CHANGEpain, it appears to finally be getting some well deserved recognition in the mainstream research realm. Over the past month the British Medical Journal (BMJ) and the British Journal of Sports Medicine (BJSM) released a series on this topic. This week at Research Corner we will briefly review the BMJ article:
