Experimental: AI-Guided Tele-rehabilitation

Participants in this arm will receive a 12-week tele-rehabilitation program guided by artificial intelligence (AI) and computer vision technology. The program consists of three personalized exercise sessions per week, delivered remotely and adapted in real time to participants' capabilities and progress. In addition, participants will attend weekly educational sessions focused on pain neuroscience to improve their understanding of chronic pain mechanisms and enhance self-management strategies.~The intervention is delivered through a visually identical digital platform used by all participants. Supervising physiotherapists monitor progress and provide standardized support but remain blinded to treatment allocation, as only the intervention group receives the active content (AI-guided exercise and PNE).

Active_comparator: Usual Care for Fibromyalgia

Participants in this arm will receive standard care for fibromyalgia, which typically includes pharmacological management such as pain relievers (e.g., paracetamol, tramadol), antidepressants (e.g., amitriptyline, duloxetine), and anticonvulsants (e.g., pregabalin, gabapentin). They will also be provided with general recommendations on physical activity and disease self-management, in line with current clinical guidelines.
