Page 42: Npcra Analysis
7 NPCRA Analysis 7.1 Introduction Traditional analysis of circadian rhythms has attempted to fit physiological indicators to a Cosine waveform shape (Cosinor analysis). Activity-rest data do not typically fit well with this type of analysis, hence the MotionWare software provides the function of Non-Parametric Circadian Rhythm Analysis (NPCRA). -
Page 43: Non-Parametric Variables
7.4 Non- Parametric Variables The NPCRA window provides a table of resulting Non- Parametric variables with the following meanings: IS (Interdaily Stability): quantifies the degree of regularity in the Activity-Rest pattern with a range of 0 to 1 where a value of 0 indicates a total lack of rhythm and a value of 1 indicates a perfectly stable rhythm. -
Page 44: Exporting Npcra Analysis Results
M10 Start Hour: Indicates the onset of the M10 sequence and provides an indication of the phase of the most active hours. RA (Relative Amplitude): First we calculate the Amplitude (AMP) which is the difference between the average activity level in the M10 and that in the L5 periods. To remove sensitivity to overall activity level, we then calculate the RA by dividing the AMP by the sum of the L5 and M10. -

Page 48: Day Activity Analysis
10 Day Activity Analysis 10.1 Overview The day activity analysis function provides an overview and summary of the activity levels of the wearer during the daytime. It is intended to assist in monitoring of the amount of time spent active on a daily or weekly basis, and the approximate intensity of that activity. -
Page 49: Selecting Days
Selecting Days To select which day of the recording to view, note the sequence of small day graphs across the top of the Day Analysis window. You can click on any of these to view that day in more detail below. You can also scroll this selection to view more days later in the recording. -
Page 50: Set Calibration
Empty Time The total amount of time when the recording did not take place – such as at the start or end of the recording (for example the difference between 00:00 and the start time or the end time and 24:00). - Page 51 counts are within an acceptable range. These can be selected as alternative calibration values but they may not reflect the values of a brisk walk and should be used with caution. Calibration periods can also be selected manually by dragging the mouse cursor over a period on the activity graph, or by entering fixed values in the thresholds fields [4].
- Page 52 Definition Physical activity includes everyday activity such as walking and cycling to get from A to B, work-related activity, housework, DIY and gardening. It also includes recreational activities such as working out in a gym, dancing, or playing active games, as well as organised and competitive sport. (See the Chief Medical Officers' [CMOs'] report.)

day of the selected week. You can see both how the time each day compares to the target time illustrated by the black line, and how it varies across the week. For instance, the graphic above clearly shows that whilst the target for moderate activity was missed during most of the week, the wearer was then very active on Saturday. -
Page 55: Totals & Averages
10.5 Totals & Averages The Totals & Averages window can be opened through the Tools menu of the Day Analysis window. This window is designed to illustrate the variation of activity over the full length of the recording. The upper graph shows the changes between weeks, and the lower graph shows the average variation within weeks. - Page 56 the recording. This shows up any variation caused by weekly patterns of behaviour. In the example shown the wearer is clearly far more active on Saturday than on an average weekday, but there is more variation within those also. Note that both graphs can be affected by the View and Options menus.
