The importance of trunk motion in wearable based infant spontaneous movement analysis.

The characteristics of spontaneous movements in infants are essential for the early detection of neurological pathologies, with the Prechtl method being a widely recognized approach. While the Prechtl method is effective in predicting motor risks, its reliance on the evaluator's expertise limits its scalability, particularly in low-income areas. In such contexts, the use of inertial sensors combined with automated analysis presents a promising accessible alternative; however, more research is necessary to get results comparable to those of the Precht method.
