Multimodal Intervention for Persistent Musculoskeletal Pain in Primary Care

Persistent musculoskeletal pain represents a major public health problem and is one of the most frequent reasons for consultation in primary care. It is associated with reduced quality of life, functional limitations, emotional distress, increased healthcare utilization, and high socioeconomic costs. Contemporary pain science recognizes that persistent pain is a multidimensional experience involving biological, psychological, and social mechanisms, including central sensitization and maladaptive cognitive-emotional processes such as catastrophizing and fear-avoidance behaviors. Current clinical practice guidelines recommend multimodal and non-pharmacological approaches as first-line management strategies. Pain neuroscience education (PNE) aims to reconceptualize pain by explaining the neurobiological and psychosocial mechanisms involved in persistent pain, thereby reducing perceived threat and maladaptive beliefs. Therapeutic exercise contributes to functional improvement, modulation of central pain mechanisms, and psychological well-being. Additionally, the promotion of self-care strategies and healthy lifestyle habits (including physical activity, sleep hygiene, stress management, and nutritional counseling) may enhance long-term outcomes and patient empowerment. This study is a multicenter, parallel-group, single-blind randomized controlled trial conducted in five primary care centers in the Comunitat Valenciana (Spain). A total of 146 adults aged 18 to 70 years with nonspecific persistent musculoskeletal pain lasting at least six months will be recruited and randomly allocated to either an experimental group receiving the multimodal intervention or a control group receiving usual care. The multimodal intervention integrates structured group-based pain neuroscience education sessions, supervised therapeutic exercise, and guidance on self-care and healthy lifestyle habits. The control group will continue to receive standard primary care management. The primary outcome is health-related quality of life assessed using the SF-36 Health Survey. Secondary outcomes include pain intensity, number of painful areas, pain catastrophizing, kinesiophobia, central sensitization, emotional symptoms, perceived social support, medication consumption, and lifestyle-related variables. Data will be collected at baseline, immediately post-intervention, and at 6- and 12-month follow-ups using the REDCap electronic data capture system. Statistical analyses will include descriptive statistics and inferential analyses to compare within- and between-group differences over time. The study aims to provide robust evidence regarding the effectiveness of a multimodal, biopsychosocial intervention delivered in primary care for the management of persistent musculoskeletal pain.
