Design and Implementation of an Antagonistic Exercise Support System Using a Depth Image Sensor
EAI Endorsed Transactions on Pervasive Health and Technology, 2017
Dementia is one of the main reasons for elderly people becoming dependent on care. Antagonistic exercise, which involves performing different movements with the upper and lower limbs on the left and right sides, is a form of exercise that uses cognitive and motor functions at the same time. Preventive care professionals who can lead this sort of exercise are few in number compared with elderly people, and are under a heavy burden. On the other hand, the Kinect has become popular as a low-cost device that can acquire human actions. In this study we designed and implemented an antagonistic exercise support system using a Kinect. The user's joint information acquired from Kinect is used to estimate the exercise, and the system provides real-time feedback to the user. We performed recognition accuracy tests with young and elderly test subjects, and carried out an interview survey to ascertain elderly user opinions.

Physical activity is recognized as one of the most effective measures to reduce risk of injury and to improve the quality of life in elderly. Many of the elderly however lack the motivation, confidence and skills to engage in regular exercise activity. One of the promising approaches is semi-automated coaching that combines exercise monitoring and interaction with a health coach. To gain a better understanding of the needs and challenges faced by the elderly when using such systems, we developed Kinect-based interactive exercise system to encourage healthy behavior and increase motivation to exercise. We present the multidisciplinary design process and evaluation of the developed system in a home environment where various real-world challenges had to be overcome.
Exercise Recognition for Kinect-based Telerehabilitation
Methods of information in medicine, 2015
An aging population and people's higher survival to diseases and traumas that leave physical consequences are challenging aspects in the context of an efficient health management. This is why telerehabilitation systems are being developed, to allow monitoring and support of physiotherapy sessions at home, which could reduce healthcare costs while also improving the quality of life of the users. Our goal is the development of a Kinect-based algorithm that provides a very accurate real-time monitoring of physical rehabilitation exercises and that also provides a friendly interface oriented both to users and physiotherapists. The two main constituents of our algorithm are the posture classification method and the exercises recognition method. The exercises consist of series of movements. Each movement is composed of an initial posture, a final posture and the angular trajectories of the limbs involved in the movement. The algorithm was designed and tested with datasets of real move...

In this study, a program was developed for leg-strengthening exercises and balance assessment using Microsoft Kinect. [Subjects and Methods] The program consists of three leg-strengthening exercises (knee flexion, hip flexion, and hip extension) and the one-leg standing test (OLST). The program recognizes the correct exercise posture by comparison with the range of motion of the hip and knee joints and provides a number of correct action examples to improve training. The program measures the duration of the OLST and presents this as the balance-age. The accuracy of the program was analyzed using the data of five male adults. [Results] In terms of the motion recognition accuracy, the sensitivity and specificity were 95.3% and 100%, respectively. For the balance assessment, the time measured using the existing method with a stopwatch had an absolute error of 0.37 sec. [Conclusion] The developed program can be used to enable users to conduct leg-strengthening exercises and balance assessments at home.

The present study aims to describe the efficacy of Kinect technology for the therapeutic rehabilitation of geriatric patients by conducting and analyzing a 8-session therapeutic program based on this technology in which 12 study subjects participated, 8 Male subjects and 4 female subjects, within the physical capacities, the muscular strength was evaluated in the Daniels scale of the flexion of the hip, knee, shoulder and elbow and the goniometry of the flexion / extension of these same members. A greater elasticity and mobility were observed by female subjects apart from a greater increase in the range of motion in the same period of time than Male subjects, with respect to muscle strength, it was not possible to demonstrate a significant advance so the effectiveness of Kinect therapy in this area still shows contrasts in its results. Objective: to describe the efficacy of kinect technology for the therapeutic rehabilitation of elderly patients by carrying out and analyzing a thera...
A Kinect-based rehabilitation exercise monitoring and guidance system
2014 IEEE 5th International Conference on Software Engineering and Service Science, 2014
In this paper, we describe the design and implementation of a Kinect-based system for rehabilitation exercises monitoring and guidance. We choose to use the Unity framework to implement our system because it enables us to use virtual reality techniques to demonstrate detailed movements to the patient, and to facilitate examination of the quality and quantity of the patient sessions by the clinician. The avatar-based rendering of motion also preserves the privacy of the patients, which is essential for healthcare systems. The key contribution of our research is a rule-based approach to realtime exercise quality assessment and feedback. We developed a set of basic rule elements that can be used to express the correctness rules for common rehabilitation exercises.

Alterations of gait and balance are a significant cause of falls, injuries, and consequent hospitalizations in the elderly. In addition to age-associated motor decline, other factors can impact gait and stability, including the motor dysfunctions caused by neurological diseases such as Parkinson's disease or hemiplegia after stroke. Monitoring changes and deterioration in gait patterns and balance is crucial for activating rehabilitation treatments and preventing serious consequences. This work presents a Kinect-based solution, suitable for domestic contexts, for assessing gait and balance in individuals at risk of falling. The system captures body movements during home acquisition sessions scheduled by clinicians at definite times of the day and automatically estimates specific functional parameters to objectively characterize the subjects' performance. The system includes a graphical user interface designed to ensure usability in unsupervised contexts: the human-computer interaction mainly relies on natural body movements to support the self-management of the system, if the motor conditions allow it. This work presents the system's features and facilities, and the preliminary results on healthy volunteers' trials.

Kinect v 2 evaluation for in-home medical rehabilitation scenarios
2016
The technology advancements greatly improved the medical services over time with virtual reality (VR) devices and applications. Currently taking advantage of these recent advancements is the medical rehabilitation field, heavily studied in past few years as a promising VR area. VR-based rehab brings several advantages over the traditional therapy and could deliver personalized in-home treatment without the need of a permanent dedicated supervisor. A device that could make this technology possible is the Microsoft’s new Kinect v2, an improved motion capture sensor available at low prices for personal use. This promising high-tech device can track body movements without the need of additional attached devices that could prove unconformable and expensive. In order to evaluate the medical rehabilitation utility for in-home usage we conducted some research studies and practical experiments focusing on the upper-part of the body in a seated pose in front of a desk. Results indicate that t...
