MediaPipe-Based Activity Analysis by Healthcare Professionals: Method Development and Technology Acceptance-A Pilot Study.

Integrating digital assessment technologies into clinical practice remains a challenge because of usability issues, time constraints, and difficulties in data interpretation. This study aimed to examine the feasibility of a clinically practical MediaPipe-based motion analysis method and to evaluate its technological acceptance by healthcare professionals. We tested an analysis method using single-camera frontal-plane videos of gait, eating, and table-slide tasks to quantify movement under both normal and simulated impairment conditions. To evaluate the clinical utility, a questionnaire based on the unified theory of acceptance and use of technology 2 (UTAUT2) was administered to physical therapists, occupational therapists, and nurses. The results provide preliminary evidence of the feasibility and technology acceptance of MediaPipe for activity analysis by healthcare professionals, even with a limited set of variables. Participants generally showed positive attitudes toward its clinical usefulness; however, challenges related to its usability were identified. These findings also suggest that specialized personnel capable of handling digital technologies may play an important role in facilitating their implementation. With further advances in digital technology, activity assessments are expected to extend beyond clinical settings to everyday environments. To achieve this, not only technological improvements, such as enhanced reliability, validity, and usability, but also comprehensive frameworks incorporating education and organizational support are important.
