Fall prevention intervention technologies: A conceptual framework and survey of the state of the art
In recent years, an ever increasing range of technology-based applications have been developed with the goal of assisting in the delivery of more effective and efficient fall prevention interventions. Whilst there have been a number of studies that have surveyed technologies for a particular sub-domain of fall prevention, there is no existing research which surveys the full spectrum of falls prevention interventions and characterises the range of technologies that have augmented this landscape. This study presents a conceptual framework and survey of the state of the art of technology-based fall prevention systems which is derived from a systematic template analysis of studies presented in contemporary research literature. The framework proposes four broad categories of fall prevention intervention system: Pre-fall prevention; Post-fall prevention; Fall injury prevention; Cross-fall prevention. Other categories include, Application type, Technology deployment platform, Information sources, Deployment environment, User interface type, and Collaborative function. After presenting the conceptual framework, a detailed survey of the state of the art is presented as a function of the proposed framework. A number of research challenges emerge as a result of surveying the research literature, which include a need for: new systems that focus on overcoming extrinsic falls risk factors; systems that support the environmental risk assessment process; systems that enable patients and practitioners to develop more collaborative relationships and engage in shared decision making during falls risk assessment and prevention activities. In response to these challenges, recommendations and future research directions are proposed to overcome each respective challenge.The Royal Society, grant Ref: RG13082
Fall Prediction and Prevention Systems: Recent Trends, Challenges, and Future Research Directions.
Fall prediction is a multifaceted problem that involves complex interactions between physiological, behavioral, and environmental factors. Existing fall detection and prediction systems mainly focus on physiological factors such as gait, vision, and cognition, and do not address the multifactorial nature of falls. In addition, these systems lack efficient user interfaces and feedback for preventing future falls. Recent advances in internet of things (IoT) and mobile technologies offer ample opportunities for integrating contextual information about patient behavior and environment along with physiological health data for predicting falls. This article reviews the state-of-the-art in fall detection and prediction systems. It also describes the challenges, limitations, and future directions in the design and implementation of effective fall prediction and prevention systems
Human Gait Database for Normal Walk Collected by Smart Phone Accelerometer
The goal of this study is to introduce a comprehensive gait database of 93
human subjects who walked between two endpoints during two different sessions
and record their gait data using two smartphones, one was attached to the right
thigh and another one on the left side of the waist. This data is collected
with the intention to be utilized by a deep learning-based method which
requires enough time points. The metadata including age, gender, smoking, daily
exercise time, height, and weight of an individual is recorded. this data set
is publicly available
A cane-based low cost sensor to implement attention mechanisms in telecare robots
Telepresence robots have been recently used for
Comprehensive Geriatric Assessment (CGA). Since the robot
can not track a person continuously, there are several strategies
to decide when to check them, from cyclic checks to simple
requests from users and/or caregivers. In order to adapt to the
user needs and condition, it is preferable to perform CGA as
soon as regularities appear. However, this requires detection
of potential issues in users to offer immediate service. In this
work we propose a new low cost force sensor system to detect
user’s condition and attract attention of CGA robots, so they
can perform a full examination on a need basis. The main
advantages of this system are: i) it can be attached to any
standard commercial cane; ii) its power consumption is very
reduced; and iii) it provides continuous information as long as
the user walks. It has been tested with several elderly volunteers
in care facilities. Results have proven that the sensor readings
are indeed correlated with the users’ condition.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tec
Real-time human ambulation, activity, and physiological monitoring:taxonomy of issues, techniques, applications, challenges and limitations
Automated methods of real-time, unobtrusive, human ambulation, activity, and wellness monitoring and data analysis using various algorithmic techniques have been subjects of intense research. The general aim is to devise effective means of addressing the demands of assisted living, rehabilitation, and clinical observation and assessment through sensor-based monitoring. The research studies have resulted in a large amount of literature. This paper presents a holistic articulation of the research studies and offers comprehensive insights along four main axes: distribution of existing studies; monitoring device framework and sensor types; data collection, processing and analysis; and applications, limitations and challenges. The aim is to present a systematic and most complete study of literature in the area in order to identify research gaps and prioritize future research directions
