Polysomnographic Features of Sleep Disturbances and REM Sleep Behavior Disorder in the Unilateral 6-OHDA Lesioned Hemiparkinsonian Rat

Table 1

Comparison of mean differences of percentage of time spent in wake-sleep stages (wake, NREM, and REM), percentage of REM epochs with muscle activity, and percentage of REM epochs with observable motor activity between control and hemiparkinsonian (HD) groups.

	Group 1	Group 2	Mean difference	95% confidence interval	value
			(Group 1-Group 2)
% time in wake	HP	Control	−30.69	−46.28, −15.09	0.001
% time in NREM	HP	Control	20.82	7.57, 34.08	0.005
% time in REM	HP	Control	9.86	6.54, 13.18	<0.001
% REM epoch with muscle activity	HP	Control	20.54	2.62, 38.45	0.028
% REM epoch with observable motor behaviors	HP	Control	36.43	6.46, 66.40	0.034
