Background: During a crucial stage of development, juvenile idiopathic arthritis (JIA) can result in chronic pain, stiffness, decreased mobility, and participation restrictions. When pharmaceutical treatment is not enough to restore function, rehabilitation is required. Case Presentation: A 15-year-old kid with rheumatoid factor-positive polyarticular JIA complained of pain and restricted movement in his right ankle, left knee, and both hands. The patient had stopped going to school, needed help with several everyday tasks, and had trouble walking. VAS discomfort of 6/10, CHAQ of 2/3, Barthel Index of 80/100, PedsQL problem score of 59/100, and a 6-minute walk test distance of 228 m were among the initial findings. Rehabilitation Intervention: The four-month multidisciplinary program consists of low-impact endurance exercises, range-of-motion exercises within pain limits, progressive strengthening, occupational therapy for hand function and self-care, paraffin baths, low-level laser therapy, joint protection education, and a home exercise regimen overseen by a carer. Outcome: VAS decreased from 6 to 0–2, CHAQ decreased from 2 to 0.125, and the 6-minute walk test distance increased from 228 to 448 meters at serial evaluations conducted at weeks 4, 9, 14, and 18. The BMI rose from 17.1 to 19.7 kg/m². The patient was able to walk, take care of themselves, and participate in school activities on their own once more. There were no negative effects linked to the treatment. Conclusion: Adolescents with polyarticular JIA who get individual rehabilitation in addition to continued medical therapy report significant clinical improvements in pain, disability, endurance, and participation.
