4. Fig 3
Bland and Altman plots for comparison of (A) weight-bearing postures, (B) nonweight-bearing postures, and (C) dynamic activity assessed by video recordings (criterion standard), CAMleg, CAMtrunk, and patients' estimations. Left panels: comparison between the video recordings and CAMleg. Middle panels: comparison between the video recordings and CAMtrunk. Right panels: comparison between the video recordings and patients' estimations. Solid lines represent the mean difference and the dotted lines represent the mean difference ± 1.96SD of the difference.

5. Supplemental Fig 1
The first parameter differentiates between dynamic activity and static postures using the SMA, a parameter for intensity of motion. The second parameter differentiates between nonweight-bearing postures and weight-bearing postures using the mean accelerometer signal of the respective axis (Ml), a parameter for orientation of the CAM.
