Abstract :
This study aimed to leverage computer vision (CV) technology to develop a technique for quantifying postural control. A
conventional quantitative index, occupational therapists’qualitative clinical evaluations, and CV-based quantitative indices
using an image analysis algorithm were applied to evaluate the postural control of 34 typically developed preschoolers. The
effectiveness of the CV-based indices was investigated relative to current methods to explore the clinical applicability of the
proposed method. The capacity of the CV-based indices to reflect therapists’qualitative evaluations was confirmed.
Furthermore, compared to the conventional quantitative index, the CV-based indices provided more detailed quantitative
information with lower costs. CV-based evaluations enable therapists to quantify details of motor performance that are
currently observed qualitatively. The development of such precise quantification methods will improve the science and practice
of occupational therapy and allow therapists to perform to their full potential.
