Neurofeedback for the management of neuropathic pain in people with diabetes
Neuropathic pain is a common complication for people with diabetes. EEG-Neurofeedback is a promising pain reducing treatment. Using signals from their brain waves, the individual gets real- time feedback on a screen of changing visual material - depending on how the brain's electrical activity lowers or dampens towards the desired signals, and over 10 treatments patients will be taught to regulate relevant activity patterns themselves to reduce pain.
There is a high demand for more effective, cheap treatments of painful DPN with no or minor side effects. This study has the potential to be a breakthrough in the treatment of DPN as it will test a new, relatively cheap and innovative treatment. If EEG-NF is found effective this will offer patients with painful DPN a new therapy, likely with minor side effects. Despite advances in understanding pain mechanisms, no new treatments for painful DPN have been made available over the past decades. This results in a low QoL for the patients with painful DPN. Again, there is therefore an urgent need to strengthen clinical multidisciplinary collaborations in an international manner to test innovative treatment strategies. This interdisciplinary, blinded, place-controlled, multicenter, international, phase II clinical trial is conducted by well-established research groups with experts within their respective fields, including psychology, neurology, neuroscience, endocrinology, and pain. If EEG-NF shows to be effective, it will be feasible to be implemented in the SDC and other relevant departments nationally and internationally.
Overall, we aim to determine the short term and long-term effects of EEG-NF compared with sham EEG-NF on self-reported pain, daily functioning and QoL in individuals with chronic painful DPN. Our hypothesis is that real EEG-NF will have significant short-term and long-term clinically meaningful pain reduction compared with sham EEG-NF.
Description of the cohort
54 participants with be recruited from Steno Diabetes Center Odense (SDCO), Steno Diabetes Center Aarhus (SDCA), and the Danish Pain Research Center in Aarhus. Participants will be people with diabetes and painful neuropathic pain for at least 6 months.
