Exploratory Study About the Implementation of Technology in the Rehabilitation

STUDY DESIGN Based on the aforementioned user scenarios, an explorative qualitive study will be conducted investigating the recommendations and requirements of both patients and healthcare professionals in the development of the smart devices. Focus groups will be organized at UZ Brussel and AZ Sint Maria Halle to collect data from the participants. These discussions will be organized until data saturation is reached. Based on expectations, the investigators estimate on average 3 focus groups for every user scenario will be needed. The recommendations proposed in these focus group discussions will be analyzed and tested in the lab to determine what smart devices are eligible for rehabilitation. The data will also be used to develop AI algorithms that will be implemented in the smart devices.

USER SCENARIOS The first scenario focuses on the registration and triggering of movement of the upper limb in patients with spatial neglect. The aim is to develop a low-budget smart device that stimulates and analyzes movement of the affected side and gives feedback when needed.

The second user scenario aims to combine different smart devices and AI algorithms to create a mobile device that can be placed on a walking aid. This smart device will give feedback in terms of stride length and cadence through visual and auditive cues. A combination of sensor analysis and computer vision will monitor the gait pattern of the patient and correct where needed. These sensors will also incorporate a fall detection system that sends out a signal when a fall is detected.

The third and final scenario describes a smart intravenous (IV) pole that monitors the location of the patient relative to the IV pole and automatically follows the patient during walking. This device consists of a tracker and an accelerometer placed on the patient, and a motorized IV pole that follows the patient and avoid obstacles through computer vision. Additionally, a fall detection system will be integrated to monitor falls.

PROCEDURE Firstly, with regard to the Sars-COV-2 pandemic, all obligated prevention measure will be followed when conducting the focus group discussion. All participants and researchers will wear face masks, maintain distance (1.5 meters) and frequently disinfect hands using alcohol-based hand sanitizer. Additionally, an adequate ventilation of the room will be maintained. If necessary, the focus group discussions will be organized online, using Microsoft Teams (Microsoft, USA).
