Investigating RELEARN Neurofeedback as Treatment for Chronic Musculoskeletal Pain

Redo-Neurosystems

Overview

This clinical investigation will be carried out as a randomized controlled trial conducted at the Northern Regional Hospital, Hjørring. This investigation will enrol 36 patients suffering from severe knee osteoarthritis pain, primarily from the orthopaedic ward at Hjørring Hospital, where potential participants will be identified during routine consultations. The RELEARN intervention consists of encephalography (EEG) neurofeedback of cerebral movement evoked signatures of pain, where the participants will be instructed in attempting to manipulate these signatures to reduce pain perception. This investigation is carried out to analyse the clinical performance and safety of the RELEARN neurofeedback software.

The participants will be randomized into treatment group A and control group B, 1:1 and be stratified based on age, sex, and ethnicity. Group A participants will be asked to attend eight sessions of RELEARN neurofeedback with an approximate duration of 45 minutes per session, and group B participants will be asked to attend eight sessions with no intervention and serve as no-treatment controls with an approximate duration of 5 minutes per session. Both groups (A and B) will undergo three follow-up sessions: one month, three months, and five months post intervention.

Interventions

RELEARN NeurofeedbackDEVICE

Standard care + The RELEARN intervention. Intervention group participants will be seen at the orthopedic ward and receive standard care for knee osteoarthrosis, defined by Danish clinical guidelines. During standard care, intervention group participants will be subject to the RELEARN intervention, consisting of encephalography (EEG) neurofeedback of cerebral movement evoked signatures of pain, where the participants will be instructed in attempting to manipulate these signatures to reduce pain perception.

Standard care controlOTHER

Standard Care control. Control group participants will be seen at the orthopedic ward and receive standard care for knee osteoarthrosis, defined by Danish clinical guidelines. During standard care, the control group participants will be asked to attend eight control sessions with no RELEARN intervention with an approximate duration of 5 minutes per session. Also, participants will undergo three follow-up sessions: one month, three months, and five months post-intervention

Outcomes

Primary Outcomes

Changes in Pain Perception
