Research Interest:

Prof. Dr. Wolnei Caumo’s research interests primarily revolve around pain management and neuromodulation approaches. He is particularly focused on investigating the neurophysiological mechanisms underlying chronic pain processing, including central sensitization and cortical excitability. Dr. Caumo’s research aims to identify biomarkers of neuroplasticity in musculoskeletal chronic pain conditions and explore therapeutic interventions to counteract maladaptive neuroplasticity. Additionally, he is interested in the therapeutic potential of non-invasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS), in modulating pain perception and improving clinical outcomes in patients with chronic pain syndromes. His work also encompasses the evaluation of pharmacological interventions and the development of personalized treatment approaches based on individual neurobiological profiles. Overall, Prof. Dr. Wolnei Caumo’s research endeavors contribute to advancing our understanding of pain mechanisms and developing innovative strategies for pain management.
