Digital Physiotherapy Coaching with Alex
Physiotherapy is a widespread and efficient method for the rehabilitation of various health problems, such as chronic diseases, injuries, and age-related health issues. In addition to face-to-face physiotherapy sessions with health professionals, exercises at home are crucial to ensure ongoing and efficient rehabilitation. However, adherence to home exercises is poor and thus, patients need to be reminded, motivated and coached in performing the exercises correctly.
Common approaches to deliver home exercises are paper-based and video-based instructions. Those have their shortcomings in reminding or motivating patients to do the exercises at home and to provide real-time feedback on how to perform the exercises related to spatial accuracy (i.e., performing an exercise according to pre-defined trajectories), temporal accuracy (i.e., performing an exercise with a pre-defined velocity), and the individual number of repetitions.
The objective of this project is therefore to develop the digital coach Alex, who motivates physiotherapy patients through a smartphone application to perform the exercises on a regular basis. Moreover, Alex leads the training sessions as a hologram in augmented reality space by demonstrating the exercises and providing real-time feedback on the patient’s exercise execution.
