Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Sleep-wake balance assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire at the start and the end of each study period | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Insomnia severity assessed using the Insomnia Severity Index questionnaire at the start and the end of each study period. 2. Parameters derived from the sleep diary (self-registered every day): 2.1. Total time in bed (TTB) = time interval in minutes between the time the patient lays down in bed and the time he gets out of bed 2.2. Sleep latency (SOL – sleep onset latency) = time interval (in minutes) between the time the patient gets ready to sleep (turns off the light or the TV) and the time he falls asleep 2.3. Number of awakenings (NR) = number of nocturnal awakenings 2.4. Duration of nocturnal awakenings (WASO – wakefulness after sleep onset) = intra-nocturnal wakefulness given by the overall sum of the wakefulness (in minutes) of nocturnal awakenings 2.5. Total sleep time (TTS) = time interval (in minutes) between the time the patient falls asleep and the time he finally wakes up in the morning minus the overnight wakefulness 2.6. Sleep Efficiency Index (SEI) = TTS/TTB*100 3. Pain assessed using the Visual Analog Scale (VAS) at the start and the end of each study period | — |
