Neuropathic pain (NP) is a common symptom arising as a direct consequence of a lesion or disease affecting the somatosensory system. The traditional approach to managing NP patients is to initiate treatment with conservative pharmacological therapy before interventional strategies. However, first-line drug treatments have shown modest efficacy with less than 50% of pain relief. Since NP is present in ~70% of patients with spinal cord injury (SCI), people with this pathology represent a reliable population to study NP. Interestingly, previous studies have shown a clear correlation between NP and changes in electroencephalography (EEG), which is a good indicator of the state of the central nervous system. Characterized and developed technology to calculate NP would have a great impact on the quality of life of the patients. Personalized pharmacological treatments would increase their efficacy. PAIN_App is built in state-of-the-art digital health technology (a smartphone app, smartwatch, and a portable EEG) and aims to identify the biosignals that determine the intensity of NP in SCI. Based on initial analysis, the data collected has shown a moderate correlation to some features of the EEG, however, more analysis are currently being conducting
