Quantitative analysis of the gaze and the kinetic/kinematic evaluation of expert and novice physical therapists during standing/sitting assistance: a pilot study

In rehabilitation practices, expert therapists are believed to proficiently observe and assist patients. However, limited research has quantified the gaze behaviors of physical therapists during patient support. This study investigated the gaze patterns of expert and novice physical therapists from a first-person perspective during the process of assisting collaborators to stand. The aim was to determine which body parts received prolonged attention and to explore the characteristics of the support provided. Seven experienced physical therapists were recruited as expert participants, and 17 physical therapy students served as novice participants. We also recruited additional students as collaborators and asked them to behave as if they were patients. Both expert and novice participants wore a wearable eye tracker while assisting the collaborators to stand. We analyzed the gaze focus on specific body parts and the center of mass sway of the collaborators. Experts spent 10.75% of the total time gazing at the head area, compared to 4.06% for novices, with experts displaying significantly longer gaze durations (
