The stepping bouts csv file provides a list of all continuous stepping bouts in the file, and their containing upright bouts. Non-upright bouts are also provided in the file for context.
| Column heading | Description |
|---|---|
| Time | Date and time encoded as a floating point number, The integer part of number represents the date. The decimal portion represents the time. (Full details at: http://support.microsoft.com/kb/210276) To view the time in Excel, follow this these instructions |
| Time (approx) | For convenience, the date and time accurate to the nearest second. This should not be used for calculations of time diffferences. |
| Data Count | Count in 0.1s resolution from the start of the recording |
| Event Type | The event type: 0 – sedentary 1 – standing 2 – stepping With the latest classification algorithm, additional event types are available: 2.1 – cycling 3.1 – primary lying 3.2 – secondary lying 4 – non-wear 5 – seated transport |
| Duration | The duration of the bout (in seconds) |
| Upright Bout Number | Each upright bout is labelled with a bout number for reference |
| Upright Bout Duration (s) | The duration of the upright bout container of the stepping bout (in seconds) |
| Num Steps | The number of steps in the stepping bout |
| Cadence | The cadence of the stepping bout |
In addition, aP4+ recordings provide the following outputs:
| Column Heading | Description |
| Longest Straight Line Time (s) | The longest continuous section of straight line stepping in the stepping bout (in seconds) |
| Straight Line Time (s) (>=15s,<30s) | The total time accumulated in the stepping bout of straight line stepping of between 15s and 30s |
| Straight Line Time (s) (>=30s,<45s) | The total time accumulated in the stepping bout of straight line stepping of between 30s and 45s |
| Straight Line Time (s) (>=45s,<60s) | The total time accumulated in the stepping bout of straight line stepping of between 45s and 60s |
| Straight Line Time (s) (>=60s) | The total time accumulated in the stepping bout of straight line stepping of >=60s |
| Cumulative Positive Height Change (m) | The cumulative positive per step height change in the stepping bout |
| Cumulative Negative Height Change (m) | The cumulative negative per step height change in the stepping bout |
