Fibromyalgia (FM) is a chronic condition characterized by widespread pain, fatigue, and sleep disturbances. International guidelines recommend including mind-body interventions in treatment plans for FM. However, access to these programs is often limited due to cost, distance, and logistical barriers. To address this issue, we developed SOS — Spaces of Relief, a digital application accessible via computer or smartphone that offers short, guided practices for pain self-management. This pilot study will evaluate the feasibility and immediate effects of four mind-body techniques delivered through the app: cardiac coherence breathing, mindfulness body scan, progressive muscle relaxation, and imagery/compassion. Fifteen FM patients are participating in two sessions per week for two weeks (four sessions total), each receiving a randomized video-based intervention. Primary outcomes include changes in perceived pain (NRS 0-10), assessed before and after each session. Secondary outcomes cover stress, emotional well-being, and perceived quality of experience. These are measured through online questionnaires administered via Qualtrics. Additionally, participants are asked to provide qualitative feedback on their personal experiences and the usability of the app through an open-ended question. Currently, data collection is ongoing. The main goal of this pilot phase is to assess the feasibility, acceptability, and adherence of the intervention, while providing preliminary evidence of its immediate impact. The findings will inform the design of an expanded trial with a larger sample size and an extended intervention period. The long-term goal is to validate SOS—Spaces of Relief—as an accessible, scalable, and cost-effective digital tool to support individuals with fibromyalgia in their daily lives.
