First comprehensive survey documents LiDAR applications in rehabilitation, post-injury care, and hospital environments from 2019–2025

A research survey reviews LiDAR use across rehabilitation settings, covering 3D body scanning, gait analysis, robotic-mounted systems, real-time monitoring for safe navigation, and activity and position recognition in studies published between 2019 and 2025.

LiDAR offers advantages over camera-based systems (which raise privacy concerns) and wearable sensors (which can be uncomfortable and prone to errors) for monitoring patient movement and providing feedback on movement accuracy.

The survey analyzes learning-based processing techniques and highlights trends, gaps, and future research opportunities—claimed as the first comprehensive survey dedicated to LiDAR for rehabilitation applications.
