Increased sleep motility and respiration rates in combat neurotic patients

Noctural rates of body movements and respiratory rates were studied in 11 combat neurosis patients and 9 normal controls. Patients had significantly higher rates of body movements in sleep stage 2, and significantly higher respiratory rates in NONREM sleep and in the second REM period than normals. In patients the rates of body movements were positively correlated with sleep efficiency indices. Since some of these patients were suspected of having non-restorative sleep syndrome, it is suggested that increased sleep motility and autonomic activity might be related to this sleep disorder.
