Relationship between sleep and pain in adolescents with juvenile primary fibromyalgia syndrome.

Study Objectives: To investigate sleep quality in adolescents with juvenile primary fibromyalgia syndrome (JPFS) and determine whether sleep abnormalities, including alpha-delta sleep (ADS), correlate with pain intensity. We hypothesized that successful treatment for pain with exercise therapy would reduce ADS and improve sleep quality.

Design: Single-center preintervention and postintervention (mean = 5.
