Feasibility of video capture in home setting
A total of 23 participants (74%) of 31 from the axSpA group uploaded
their home recorded videos, and one participant did not use their
calibration grid correctly during the videos. Based on these
participants, the CV-aided system produced an output in 84% for
tragus-to-wall, 76-84% for shoulder flexion, 84% for lumbar forward
flexion, 84-88% for lumbar side flexion, 84-88% for hip abduction,
88% for cervical rotation, 88% for hip internal rotation, and 80% for
the 5xSTS. Thirty non-back pain participants (96%) out of 31 uploaded
their videos; one participant did not use utilise their calibration grid
in the videos. Data from uploaded videos could be analysed for 71% for
tragus-to-wall, 77% for shoulder flexion, 84% for lumbar forward
flexion, 81-84% for lumbar side flexion, 87% for hip abduction, 84%
for cervical rotation, 84% for hip internal rotation, and 87% for
5xSTS.
