Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Study i) The feasibility of the accelerometers during the movement-protocol in lab-gym situation, and the validity of the different parameters calculated by the software of the accelerometers compared to visual observations (video). Study ii) The validity, feasibility and test-retest reliability of the selected accelerometer in measuring habitual physical activity of children with a mitochondrial disorder during a longer period in the home situation | — |
Secondary
| Measure | Time frame |
|---|---|
| The different parameters calculated by the software of the selected accelerometer, i.e.: o Activity counts (counts/minute) o Physical activity intensity (% sedentary, % light, % moderate, % vigorous) o Steps taken (n) o Body position (% laying, % sitting, % standing, % walking) o Energy expenditure (MET-rates, kcal) o Sleep-parameters (total sleep time, sleep efficiency, sleep onset latency and wake after sleep onset) | — |
