Follow up of patients with chronic pain using a mobile phone app with a support center: unicenter prospective study.

Background: Chronic pain is one of the most common diseases in the world and requires a multidisciplinary treatment approach. Spinal cord stimulation is a possible treatment option, but these patients require close follow-up, which is not always feasible. Introduction: eHealth apps also offer the possibility of closer patient follow-up, although adherence tends to decrease over time, dropping to around 60%.
