[Abstract] Information Management in IoT Cloud-Based Tele-Rehabilitation as a Service for Smart Cities: Comparison of NoSQL Approaches

 

Abstract

Nowadays, recent advancements in ICT have sped up the development of new services for smart cities in different application domains. One of these is definitely healthcare. In this context, remote patient monitoring and rehabilitation activities can take place either in satellite hospital centres or directly in citizens’ homes. Specifically, using a combination of Cloud computing, Internet of Things (IoT) and big data analytics technologies, patients with motor disabilities can be remotely assisted avoiding stressful waiting times and overcoming geographical barriers. This paper focuses on the Tele-Rehabilitation as a Service (TRaaS) concept. Such a service generates healthcare big data coming from remote rehabilitation devices used by patients that need to be processed in the hospital Cloud. Specifically, after a feasibility analysis, by using a Lokomat dataset as sample, we measured and compared the performances of four of the major NoSQL DBMS(s) demonstrating that the document approach well suits our case study.

[Abstract] Trial operation of a cloud service-based three-dimensional virtual reality tele-rehabilitation system for stroke patients

Abstract:

We developed a tele-rehabilitation system to improve community rehabilitation for patients who are discharged early from hospital. The developed tele-rehabilitation system consists of devices designed to reduce the physical and economic burden on users while promoting optimum user movement. A Backend-as-a-Service cloud computing service was used for the communication between terminals. A non-contact sensor, Kinect, was used to measure movement. In addition, we used a three-dimensional (3D) display to present 3D images using binocular parallax, to encourage smooth movement of patients. We used this system for stroke patients and found improvements in task-performance time, smoothness of movements, and range of motion in all patients. No major issues occurred during the tele-rehabilitation. These results demonstrated the high operability and efficacy of our cloud service-based 3D virtual reality tele-rehabilitation system.

[ARTICLE] MoMiReS: Mobile mixed reality system for physical & occupational therapies for hand and wrist ailments

The MoMiReS is a mobile mixed reality system aimed at physical and occupational therapies. The goal of the system is to engage therapy patients by involving them in a fun to play 3D game environment through physical interactions with a wireless sensor glove. Our system offers a solution for rehabilitation of the hand, wrist originated problems with a smartphone based mobile mixed reality game that will be used in conjunction with traditional rehabilitation programs such as home treatment.

The key factor in the success of the home treatment is compliance of patients to the given therapy instructions. However, therapists report that patients do not carry on their home-exercises and activities. The main reason is the lack of motivation and boredom for the given activities. These activities require patients to carry out set of repetitive movements. The lack of motivation in exercises causes discontinuity and increases the recovery time and eventually increases the cost of the treatment.

Therefore, we propose a complete framework by reducing the drawbacks of the traditional therapy. Our framework has three components; hardware, smartphone game, and cloud for data storage and processing. A sensor glove was developed with plug and play motion sensors streamed in real-time to the mobile phone with Bluetooth connection. The glove is used for tracking finger pressures and motion of the fingers. The patient side smartphone based interactive game verifies compliance of the motions for assigned exercises by occupational/physical therapist. The cloud side aims at ensuring patients that the assigned exercises are carried out and also monitors patient in real-time. Cloud application keeps the record of the patients’ progresses for further analysis by therapists.

In order to understand the effectiveness of the proposed system, we developed games specifically for treatment of carpal tunnel syndrome. The usability and effectiveness of the systems are surveyed among the occupational – herapy students. Survey results show that 92% approval rate of the system.

[ARTICLE] MotionTalk: Personalized home rehabilitation system for assisting patients with impaired mobility – Full Text

…In this paper, we design and prototype a personalized home rehabilitation system, MotionTalk, for the real time quantitative assessment of mobility. Performance of rehabilitation is designed to be assessed using the changes in mobility, reflected in the exercises performed by patients at home with respect to the same exercises performed in the clinic. Our system is capable of capturing motion using Microsoft Kinect and analyzing the position and rotation information to give scores for assessing rehabilitation progress. In comparison to conventional rehabilitation systems, MotionTalk is an inexpensive (<$150 compared to conventional systems costing >$1000), less intrusive and personalized home rehabilitation system, which was developed and tested using data from ablebodied volunteers at Georgia Institute of Technology…
