Abstract
Background/Objectives: Pediatric chronic pain requires individualized care. The Pediatric Pain Screening Tool (PPST) allows for stratification of psychosocial and physical risk factors and may guide targeted interventions. However, its integration into multimodal physiotherapy programs remains unexplored. This exploratory feasibility case series study evaluated a PPST-guided, risk-stratified multimodal physiotherapy intervention in children aged 8-17 years with chronic pain. Methods: Participants were classified as low, medium, or high risk. Interventions were tailored accordingly. Outcomes were assessed pre- and post-intervention and included pain intensity, pain interference, psychological distress, and quality of life. Results: Ten participants (mean age = 13.5 years; 60% girls) were included. Six were classified as high, three as medium, and one as low risk based on the PPST. After an 8-week physiotherapist intervention program, pain interference significantly decreased (MD = -7.5; p = 0.040; d = 1.69), as did pain intensity at rest (MD = -3.1; p = 0.002; d = 2.60) and during movement (MD = -3.0; p = 0.004; d = 2.55), exceeding the MCID of 1.92. In the high-risk group, reductions were observed in anxiety (p = 0.006; d = 2.36), pain-related worries (p = 0.001; d = 3.79), fear of movement (p = 0.015; d = 1.62), and fear of pain (p = 0.002; d = 3.37). Eighty percent reported feeling "a great deal better" in the PGIC including all high-risk participants. Conclusions: These results supports the feasibility of integrating PPST risk stratification into multimodal management, providing a structured and effective framework for addressing pediatric chronic pain.
