Date of correction: July 16, 2010 Reason for correction: - Correction: ABSTRACT Details: Wrong : The nocturnal sleep patterns of 10 cerebral palsied subjects were reported in terms of the changes from night 1 to night 2 in the sleep laboratory.
Laboratory adaptation occured after night 1 for several parameters. The following summary is based on the comparisons between night 1 and night 2 results.
From the EEG profile, a reduction in the latency to the first stage 1-REM, and an increase in time spent in stage 2 and stage 1-REM were observed (Tables 1 & 2).
The respiration rate per minute significantly decreased in stage 0 and stage 3, and the changes in other stages were in the same direction (Table 3).
These finding confirmed the laboratory adaptation phenomena in cerebral palsied subjects already observed and the tendencies were in same direction of normal data which was previously reported. And they support the concept of an increased state of vigilance on the first night, which also indicated a frequent tendency to miss or skip the first stage 1-REM on the first night (Fig. 2).
In addition the comparison of the changes in sleep parameters between arousal and sleep state revealed a remarkable decrease in muscle tention (Fig. 4), and an increase in regularity of the respiration curve (Figs. 4 & 5). It was observed, as to the respiration curve, the regular cycles were frequently disordered in slow wave sleep as well as stage 1-REM. These disorders might be of a pathological nature.
Abnormal tension in cerebral palsied subjects was discussed from the point of view of psychophysiology.
Right : 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.

Abstract

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.
