About

This study follows the successfully completed HOLOBalance project which was funded by the EU Horizon 2020 scheme. TheHOLOBalance platform delivers exercises demonstrated via a hologram of the physiotherapist and corrected in real time by the hologram prompts based on performance monitoring via sensors. Further information is available at: https://holobalance.eu/. HOLOBalance was developed as a comprehensive rehabilitation protocol for individualised remote (tele)rehabilitation balance physiotherapy programme. It includes different multisensory balance and gait exercises, physical activity and memory training and exergames (video games which are also exercises) to improve balance function in older adults. The system can thus assess and remotely monitor how users are performing the exercises.

This pilot testing of a multisite randomised control trial (TeleRehab DSS, short for TeleRehabilitation Decision Support System) aims to investigating the usability and feasibility among a smaller sample population at each clinical site, identifying any technical bugs, and/or clinical procedural flaws to be remedied before delivery of the full-scale RCT.

Full description

This is a multi-centre pilot study to test the usability and feasibility of the TeleRehab DSS platform among a sample population across all five clinical sites.

Upon meeting the initial inclusion criteria, eligible participants will be scheduled for an appointment to attend the clinic and complete a cognitive assessment (MoCA) and gait assessment (FGA). If a participant is deemed fully eligible, they will proceed with the onboarding process and clinical assessment, including the collection of personal details and a set of health questionnaires. They will then be randomised into either the high-tech or low-tech TeleRehab DSS intervention group.

All study participants will attend two sessions weekly over 3-weeks at each clinical site, where they will complete a personalised multisensory balance rehabilitation programme using augmented reality while wearing motion tracking sensors. Clinicians will be present to attend to any technical or clinical queries during completion of the program. At the end of the 3-weeks, the artifical intelligence decision support system will suggest exercise progressions, tracking wether the clinical agrees or disagrees with these suggestions.

Participants will receive telephone calls each week to monitor their progress. Participants will also receive remote program reviews at weeks 3, 6 and 9, from a member of the research team to assess and change exercises as required. Participants will be advised to contact the research team by email or by telephone during working hours if they have concerns or questions about their rehabilitation program or the TeleRehab DSS system. The research team will judge whether an additional home visit is required. If a patient does not complete their exercises for three consecutive days, a flag/warning will appear on the patients dashboard as a priority patient to follow up with, within 24 hours.

TeleRehaB DSS supported, prescribed, progressed and delivered intervention. In the TeleRehaB DSS IG, the platform will suggest two possible management strategies, on an individualised basis, based on patient profiles and expected benefit: 1)The high-tech, full TeleRehaB DSS with all components of the intervention consisting of TeleRehaB DSS AI-progressed multisensory balance exercises with the use of the AR avatar, real time feedback, AR gamified intervention, sensor monitored exercise performance and additional cognitive training, 2) the low-tech, basic version of TeleRehaB DSS, with depth camera, sensors and tablet - multisensory balance exercises, real time feedback, sensor monitored exercise performance and cognitive games, with no exergames, no smartwatch, and no mobile phone. The clinician can override the TeleRehab DSS group allocation decision if it is deemed unsafe.
