| Measure | Time frame |
|---|---|
| Main Objective: Sleep duration (min) Basis: validated sleep depth index SFx (developed by Dimpfel, 1998) in comparison to placebo.;Secondary Objective: A) on the neurophysiological site the parameter extracted from polysomnography (Todorova et al., 1997): A1) sum of times where absolute delta- and theta-power is present over the tested night (quantitative EEG parameter). A2) REM sleep latency, A3) sleep efficiency (related to total time in bed) [%], A4) total time of deep sleep [min], A5) total time of being awake [min], A6) counts of awakening events during the night sleep. B) on the clinical site, subjectively by the volunteer estimated: B1) sleep quality B2) feeling of recovery (GES, Basis SF-A). ;Primary end point(s): One confirmatoric goal parameter (total sleeping time (S-Dauer)) over the total re-corded period of 8 h (10.00 p.m. at evening to 6:00 a.m. at the following morning)*. The validated SFx-Parameter (dependent from time) will be used: S-Dauer =: Integral (from 0 to 480 min*) over time f(SFx(t)) dt. whereby f(SFx(t)) = min (1, (max (0, (80 - SFx(t))/3)). (min = Minimum, max = Maximum). S-Dauer describes the time duration of the sleep*. | — |
