ePHoRt: Towards a Reference Architecture for Tele-Rehabilitation Systems

Abstract

In recent years, the software applications for medical assistance, including the telerehabilitation, have known a high and a continuous presence in the medical area. The ePHoRt is a Web-based platform for the remote home monitoring rehabilitation exercises in patients after hip replacement surgery. It involves a learning phase and a serious game scheme for the execution and evaluation of the exercises as part of a therapeutic program. Modular software architecture is proposed, under the patient perspective, to be used as a reference model for researchers or professionals who wish to carry out tele-rehabilitation platforms, and to guarantee security, flexibility, and scalability. The architecture incorporates two main components. The first one manages the patient' therapeutic programs taking into account two principles: 1) maintain loose coupling between the layers of the framework and 2) Don't Repeat Yourself (DRY). The second one evaluates the performed exercises in real time considering an independent acquisition mechanism for the patient movements and two artificial algorithms. The first algorithm allows evaluating the quality of the movements, while the second one allows assessing the levels of pain intensity by recognizing the patient' emotions when performing the movements. Details of the components and the meta-model of the architecture are presented and discussed considering their advantages and disadvantages.

Technical aspects of virtual augmented reality-based rehabilitation systems for musculoskeletal disorders of the lower limbs: a systematic review

“…Among the studies, 11 (55%) used Kinect technology as input tools [ 33 , 34 , 37 , 38 , 41 , 43 – 46 , 49 , 52 ].…”

“…Kinect can provide real-time, in-depth skeleton tracking information of 20 joints and red, green, and blue (RGB) images for movement recognition [ 46 ]. Among the studies, 2 (10%) used the dynamic time warping (DTW) algorithm to distinguish between right and wrong movements [ 34 , 45 ]. This algorithm processes the skeletal data [ 34 ].…”

Home-based telerehabilitation: A review of remote therapy frameworks

“…The exergame provides an ankle muscle strengthening exercise using the rotation information and pressure information from the wireless wobble board as input. Furthermore, the work of (Pérez-Medina et al, 2019) brought the concepts of real time evaluation, flexible and modular software architecture to the Web Based Framework.…”

Uma Abordagem Baseada No Aprendizado De Máquina Interativo E Interação Natural Para Apoio À Reabilitação Física

“…-Baixo custo e portabilidade: o sistema deve ser usado em um computador, notebook ou tablet ( [Wairagkar et al 2017]) sem a necessidade de hardware especial. Adicionalmente, os sistemas baseados em arquitetura web são de interesse não apenas para os pacientes e suas famílias, mas também para os profissionais de saúde, uma vez que podem ser acessados de qualquer computador, além de economizar custos de infraestrutura [Pérez-Medina et al 2019].…”
