Design outcomes
Primary
| Measure | Time frame |
|---|---|
| When used Low-Frequency Therapy Equipment versus not used, each case weighed the impact on REI/ODI calculated from a Sleep Evaluation Device. Day 1, 2 is not used, and Day 3 sleep is used Low-Frequency Therapy Equipment. The intended subjects are Day 2 REI 40 or more, Primary Outcomes are used Low-Frequency Therapy Equipment. The improvement cases define the availability as 50% or more than Day 2 REI, or 25% or more than Day 2 ODI. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1)REI/ODI improvement rate when Day 2 REI is more than 20 but less than 40%. 2)REI/ODI improvement rate when Day 2 REI is more than 5 but less than 40%. 3)REI/ODI improvement rate when Day 2 REI is more than 20 but less than 50%. 4)A hypnic headache attack in morning, a subjective symptom about wake after sleep onset (Day 1, Day 2, Day 3) | — |
