Sleep and restless legs syndrome in female adolescents with idiopathic musculoskeletal pain

Abstract Objectives: To assess the presence of restless legs syndrome, periodic leg movement, and sleep disorders in female adolescents with idiopathic musculoskeletal pain through a sleep scale and polysomnography, and to compare these data in adolescents without pain history. Method: Twenty-six adolescents diagnosed with idiopathic musculoskeletal pain followed in a pain outpatient clinic and 25 healthy controls matched by age and education were recruited. The restless legs syndrome criteria were evaluated according to the International Restless Legs Syndrome Study Group, the Sleep Disturbance Scale for Children was completed, nocturnal polysomnography was performed, and anxiety symptoms were recorded. Results: The mean age of idiopathic musculoskeletal pain adolescents was 13.9 ± 1.6 years; in controls, it was 14.4 ± 1.4 years. One adolescent in the control group (4 %) and nine patients with idiopathic musculoskeletal pain (34.6 %) fulfilled the restless legs syndrome criteria (p = 0.011). The authors did not observe significant differences in Sleep Disturbance Scale for Children scores between the groups in all components: disorders of initiating and maintaining sleep (p = 0.290), sleep breathing disorders (p = 0.576), disorders of arousal (p = 0.162), sleep-wake transition disorders (p = 0.258), disorder of excessive daytime somnolence (p = 0.594), and sleep hyperhidrosis (p = 0.797). The neurophysiological, respiratory, and periodic leg movement parameters were similar in both groups. Having anxiety was not associated with restless legs syndrome (p = 0.11). Three patients with idiopathic musculoskeletal pain (11.5 %) presented restless legs syndrome and periodic leg movement simultaneously, which was absent in the control group. Conclusion: Female adolescents with idiopathic musculoskeletal pain present criteria for RLS more frequently than healthy adolescents. However, this study did not observe relevant changes in objective and subject sleep variables.
