Relationships between FAQ, laboratory-based self-selected cadence, and age. (A) Age and cadence. (B) Age and FAQ. (C) FAQ and cadence. Square, hemiplegic; cross, diplegic; circle, quadriplegic. Best linear fit shown for R2>.25. Note that gradients not statistically significant (P>.05).

4. Fig 3
F-LPA outcomes. Mean daily total upright time is illustrated as 2 stacked bars of standing time and stepping time. Participants are ordered by condition, then FAQ, and then age. The mean number of STS transitions (equal to the number of upright events per day) is included below the graph, with the mean number of steps taken per day given above the relevant column.

5. Fig 4
Relationship between free-living mean steps taken per day and mean time spent (A) stepping, (B) standing, and (C) the number of STS transitions per day of all participants. Square, hemiplegic; cross, diplegic; circle, quadriplegic. Best linear fit shown for R2>.25. *P<.05 for gradient of line.

6. Fig 5
Relationship between age (A–D), FAQ (E–H), and laboratory-based cadence (I–L) and free-living mean standing time, stepping time, steps, and STS transitions per day for all participants. Square, hemiplegic; cross, diplegic; circle, quadriplegic. Best linear fit shown for R2>.25. *P<.05 for gradient of line.
