B-4 Statistic Definitions
Percent Immobile
a) The percentage of Scored Total Immobile Time to (Interval Duration minus
Total Invalid Time (Activity)), for the given interval. b) (Scored Total Immobile
Time divided by (Interval Duration minus Total Invalid Time (Activity))
multiplied by 100.
Number of Immobile Bouts
The total number of continuous blocks, one or more epochs in duration, with
each epoch of each block scored as IMMOBILE, between the Start Time and the
End Time of the given interval.
Average Duration of Immobile Bouts
The Scored Total Immobile Time [see above] divided by the Number of
Immobile Bouts [see above], for the given interval.
Scored Total Mobile Time
(The total number of epochs between the Start Time and the End Time of the
given interval scored as MOBILE by Actiware software) multiplied by the Epoch
Length in minutes (so the Scored Total Mobile Time is in minutes). Note: In
order to be scoreable as IMMOBILE or MOBILE, an epoch must have a valid
physical activity count [see Total Invalid Time (Activity), above].
Percent Mobile
a) The percentage of Scored Total Mobile Time to (Interval Duration minus Total
Invalid Time (Activity)), for the given interval. b) (Scored Total Mobile Time
divided by (Interval Duration minus Total Invalid Time (Activity)) multiplied by
100.
Number of Mobile Bouts
The total number of continuous blocks, one or more epochs in duration, with
each epoch of each block scored as MOBILE, between the Start Time and the
End Time of the given interval.
Average Duration of Mobile Bouts
The Scored Total Mobile Time [see above] divided by the Number of Mobile
Bouts [see above], for the given interval.
Number of Immobile Bouts 1 Minute in Duration
The total number of continuous blocks 4 epochs in duration if Epoch Length = 15
seconds, 2 epochs in duration if Epoch Length = 30 seconds, 1 epoch in duration
if Epoch Length = 60 seconds (not applicable if Epoch Length is greater than
60 seconds), with each epoch of each block scored as IMMOBILE, between the
Start Time and the End Time of the given interval.
Percentage of Number of Immobile Bouts 1 minute in duration to the Number
of Immobile Bouts
a) The percentage of Number of Immobile Bouts 1 Minute in Duration to the
Number of Immobile Bouts [see above], for the given interval. b) (Number of
Immobile Bouts 1 Minute in Duration divided by Number of Immobile Bouts)
multiplied by 100.
Fragmentation Index
The sum of Percent Mobile [see above] and Percent Immobile Bouts Less Than
1-Minute Duration to the Number of Immobile Bouts, for the given interval. Also
known as the Index of Restlessness or Movement and Framentation Index.
