Description

<p>To evaluate sleep effect of automatic back-lowering by electric bed, we compared subjective sleep quality, sleep posture recorded by an infrared video camera, and objective sleep variables measured by a sheet-shaped body vibrometer between horizontal condition and automatic back-lowering condition (back angle to the horizontal of 10 degrees, it was decreased automatically and intermittently after measuring continuous 20 minutes sleep after sleep onset). Twelve healthy subjects (6 males, 6 females; aged 20-26) slept in the laboratory for 2 consecutive nights. The order of conditions was counter balanced. The results showed that statistically significant differences were not found between the two conditions.</p>
