Play Later Play Later Lists Like Liked📰 Can post-surgical pain really not affect physical activity? Dr. Marcus Komann’s groundbreaking study reveals a surprising disconnect between pain levels and movement, challenging what we thought we knew about recovery. 🧑⚕️📊 In this thought-provoking episode, Dr. Olli Tikkanen sits down with Dr. Marcus Komann, a distinguished IT coordinator and researcher at Jena University Hospital, to explore the unexpected findings from a comprehensive European-funded study on post-surgical pain and patient mobility. Dr. Komann, with a unique background in computer science and artificial intelligence, transitioned into the medical field and has spent the last 15 years investigating the complexities of pain, an area notoriously difficult to quantify. During the discussion, Dr. Komann delves into the intricacies of measuring pain—a subjective experience that lacks a definitive gold standard—and the challenges this presents in clinical research. He explains the ambitious goals of their study, which aimed to harmonize pain questionnaires across different research settings to improve the comparability of results. Through their work, which involved tracking patients undergoing various types of surgery, they uncovered a surprising lack of correlation between pain levels and physical activity in the immediate post-surgical period. Contrary to what many might expect, patients with higher pain levels did not necessarily exhibit reduced physical activity, suggesting that pain and activity may be separate dimensions of recovery. The conversation also touches on the psychological and social aspects of pain, highlighting how factors like anxiety, self-efficacy, and social status can influence a patient's pain experience and recovery trajectory. Dr. Komann discusses the implications of these findings for pain management in clinical settings, emphasizing the need for healthcare providers to consider both pain and physical activity independently when assessing patient recovery. This episode is a must-listen for researchers, clinicians, and anyone interested in the evolving science of pain and rehabilitation. _________________________________________________________ This podcast episode is sponsored by Fibion Inc. | Better Sleep, Sedentary Behaviour and Physical Activity Research with Less Hassle --- Collect, store and manage SB and PA data easily and remotely - Discover ground-breaking Fibion SENS --- SB and PA measurements, analysis, and feedback made easy.

He was first drawn to Alzheimer’s disease (AD) research through the connection between sleep health and AD, and the prevention, detection and potential treatment implications of this connection. Cook believes sleep health disparities across underrepresented groups may help explain disproportionate risk of AD. He is currently completing his dissertation, and intends to pursue a career in behavioral sleep medicine as a clinical psychologist. ___________ This podcast episode is sponsored by Fibion Inc.
