The sleep patterns of 10 cerebral palsied subjects were studied in terms of the changes from night 1 to night 2 in the sleep laboratory. The following significant changes occured after night 1 for several parameters: 1) a reduction in the latency to the first stage 1-REM, 2) an increase in time spent in stage 2 and stage 1-REM, 3) a decrease in respiration frequency in stage 0 and stage 3. These findings confirmed the laboratory adaptation phenomena. The comparison of the changes in sleep parameters between arousal and sleep stages revealed a remarkable decrease in muscle tention and increase in the regularity of the respiration curve. Relaxation and abnormal tension were discussed from the psychophsiological standpoint.
