Introduction Fibromyalgia (FM) is a disorder characterized by chronic pain, with significant medical, psychological, and socio-economic implications. Although there is limited evidence, cognitive-behavioral therapy (CBT) has shown to be effective in improving FM symptoms. An alternative to enhance CBT effectiveness is to incorporate digital therapeutics (DTx). Aim We conducted a pilot study to investigate whether the addition of a DTx intervention ( VirtualPain) to cognitive-behavioral group therapy (CBGT) can reduce pain perception and associated symptoms in patients with FM. Method Ten patients with FM were initially recruited from a public hospital in Barcelona. The treatment consisted of 6 weeks of VirtualPain group sessions and 16 weeks of CBGT. Measures of catastrophizing, self-efficacy, and coping were recorded before, during, and after the protocol. In the DTx sessions, pain intensity was recorded before and after each session. Results The program (DTx and CBGT) showed a significant improvement in pain-related self-efficacy and relaxation measures. Improvement in pain perception was observed only after the DTx intervention. Conclusions This study provides preliminary results regarding the added value of DTx ( VirtualPain) as part of a CBGT for FM. The use of the program has facilitated a significant reduction in pain perception in each of the VirtualPain sessions, which provides further evidence of how this technology can be beneficial for improving FM treatments.
