Neurophysiology of pain education knowledge, pain disability, patient satisfaction and central sensitization in chronic musculoskeletal pain

Abstract

Chronic musculoskeletal pains are multifaceted, and Central sensitization is a potential pathophysiological mechanism underlying a group of chronic musculoskeletal pain disorders. Neurophysiology of pain education knowledge and patient satisfaction levels of chronic musculoskeletal pain subjects may contribute to central nervous system sensitization. Hence, the aim of the study was to evaluate the impact of neurophysiology of pain education knowledge and patient satisfaction levels on central sensitization in large population of patient with chronic musculoskeletal pain. The study included 200 chronic musculoskeletal pain subjects that persisted more than 3 months with average age of 43.93±13.62. A cross-sectional study used non probability sampling. Neurophysiology of pain Questionnaire (NPQ) to know the conceptualization of pain, mood rating scale(MRS) to measure patient’s mood fluctuation because of pain, pain disability scale (PDS) for evaluating patients ability to perform certain activity, central sensitization inventory(CSI) to measure nervous system sensitization and patients satisfaction scale(PSS) to understand patient’s satisfaction towards the treatment and health care provider were used. Descriptive and correlation analyses were used for analysis. The correlation analyses showed that patient disability scale negatively correlated with mood scale and positively correlated with the age, duration of the condition, impact of pain on ADL and central sensitization. And there was a positive correlation between patient satisfaction and impact of pain on ADL. The age, mood, duration of the condition and pain disability were the factors behind central sensitization in patients with chronic musculoskeletal pain. And the neuro physiology of pain knowledge had impact on pain disability and patient satisfaction.
