inflammatory back pain
Characteristic pattern of spinal pain in pediatric spondyloarthritis, featuring morning stiffness, improvement with activity, and onset before age 16 years.
Full Definition
Inflammatory back pain in children and adolescents represents a distinct clinical pattern that suggests underlying spondyloarthritis. Key features include insidious onset before age 16, duration of at least 3 months, morning stiffness lasting more than 30 minutes, improvement with exercise and activity, pain that worsens with rest, and frequent nighttime awakening due to pain. This pattern differs significantly from mechanical back pain, which is more common in adults and typically worsens with activity. Recognition of inflammatory back pain in young patients is crucial for early diagnosis of juvenile spondyloarthritis and initiation of appropriate treatment to prevent spinal fusion and disability.
Usage
Usage note: Key distinguishing feature from mechanical back pain; requires careful history-taking to identify characteristic pattern.
