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.

背景/目的： 儿科慢性疼痛需要个体化护理。儿科疼痛筛查工具（PPST）允许对心理社会和身体风险因素进行分层，并可能指导针对性的干预措施。然而，将其整合到多模式物理治疗项目中的研究尚未开展。本项探索性可行性病例系列研究评估了针对8至17岁慢性疼痛儿童的风险分层、由PPST引导的多模式物理治疗干预。方法： 参与者被分类为低风险、中等风险或高风险。根据其风险级别量身定制相应的干预措施。在干预前后评估的结果包括疼痛强度、疼痛干扰、心理困扰和生活质量。结果： 共有10名参与者（平均年龄= 13.5岁；60%为女孩）被纳入研究。根据PPST，六人为高风险，三人为中等风险，一人为低风险。经过8周的物理治疗师干预项目后，疼痛干扰显著降低（MD = -7.5；p = 0.040；d = 1.69），静息时的疼痛强度也有所下降（MD = -3.1；p = 0.002；d = 2.60）和运动时的疼痛强度也有所降低（MD = -3.0；p = 0.004；d = 2.55），超过了MCID的1.92。在高风险组中，观察到焦虑、与疼痛相关的担忧、对运动的恐惧以及对疼痛的恐惧均有所减少。结论： 这些结果支持将PPST的风险分层整合到多模式管理中的可行性，为解决儿科慢性疼痛提供了一个结构化且有效的框架。
