BACK-to-MOVE: Machine learning and computer vision model automating clinical classification of non-specific low back pain for personalised management
Fig 5
Spine flexion angle waveform of a single participant repeating the movement with the signal pre-smoothing (blue) and post-smoothing (orange).
The spine flexion repetition time (tri), and angle depth (depthi) are highlighted in the graph to give insight into the consistency of participants attainment of a specific flexion depth and the extent to which the flexion depth fluctuated across repetitions.
