Stim | Sham | p Value | |
---|---|---|---|
W | 1.55% (0.69) | 4.11% (3.21) | 0.44 |
N1 | 3.61% (1.00) | 2.19% (0.64) | 0.23 |
N2 | 44.50% (3.47) | 39.33% (3.89) | 0.33 |
SWS | 39.69% (3.34) | 40.85% (4.32) | 0.83 |
REM | 9.25% (1.35) | 7.39% (1.48) | 0.36 |
MA | 1.39% (0.29) | 0.89% (0.20) | 0.17 |
Total sleep time (min) | 394.4 (15.6) | 398.5 (11.1) | 0.83 |
Sleep characteristics during the 210 min stimulation period showing the average time spent in each sleep stage demonstrates that the percentage of time spent in each condition (W, wake; N1, stage 1; N2, stage 2; MA, muscle artifact) was similar during the stimulation period, suggesting that stimulation did not disrupt sleep or increase the overall time spent in NREM sleep.
