StraightenUp: Implementation and Evaluation of a Spine Posture Wearable
International Conference on Ubiquitous Computing and Ambient Intelligence, 2017
Human posture and activity levels are indicators for assessing health and quality of life. Maintaining improper posture for an extended period of time can lead to health issues, e.g. improper alignment of the vertebrae and accelerated degenerative disc. This, in turn, can be the cause of back pain, neurological deterioration, deformity, and cosmetic issues. Some wearable prototypes have been proposed for spine posture monitoring, however, there has not been enough consideration for the users’ experience with these devices, to understand which characteristics are central to acceptance and long-term use. This paper presents a prototype of a low-cost spine posture wearable, along with its preliminary evaluation, which aims both to confirm that the wearable can measure spine posture and to evaluate user experience with this device. The results show that the wearable was comfortable, causing a sensation of security, and that feedback to users would be needed to help improve posture. Further work is required to make sure the device is easy to put on and remove, and discreet enough to be worn in public.
Real Time Monitoring of Posture to Improve Ergonomics
Journal of Biomedical Engineering and Medical Imaging, 2015
Back pain is one of humanities most frequent complaints. While dangerous diseases are being combatted on a daily basis, something as simple as bad posture is often overlooked. Bad posture can start off as a simple habit and soon lead to chronic back pain. Thus it is essential to maintain an ideal posture so as to reduce stress on the body. In this paper, monitoring of posture is done using flex sensor placed along the spine to detect the movement or bend. As posture changes from 'ideal' to 'poor', the user is alerted through a buzzer and LCD. A microcontroller is used to set the limits of ideal posture, which can be user specific. A load cell is used to monitor the variation in body weight and spine stress for poor and ideal postures under sitting and standing cases. The proposed system aims to implement a simple posture monitoring and correction system that can be set up at the work place with ease. This can serve to prevent cases of scoliosis and other spine issues which often start with poor posture.

The bad sitting posture leads to many back problems for young people. Nowadays the adults and young people seat for long hours hunching over their laptops and tablets. Recent researches are focus on the study and develop systems to prevent the seated persons from spinal pain with monitoring and improve the sitting posture in real-time. In this study we analyze the specification of sitting posture monitoring systems, the information required to define the human posture, the technologies used and the systems limits. The person posture can be identified by different information provided by the sensing technologies. This research can be a reference for future study for posture monitoring systems.

Lower spinal back pain problem treatments costs to billions of dollars every year. Low back pain is often caused by improper seating posture, which in turn affect the spinal muscles. Regularly switching shape and maintaining proper posture helps to improve and maintain a person's health and prevents muscular problems. By indulging into sedentary lifestyle and working long hours in front of technology, good body shape of people gets deteriorated and leads to abandoning of spine health. Proper posture plays an important role to lead a healthy lifestyle. Back pain is the one of the major reasons for people of young age group to seek medical help. The human ability to stay upright has been compromised over a past few years, and health is been overshadowed by improper routine. The purpose of this project is to identify and implement strategies that can be practically used to determine spinal posture alignment. The system identifies and records the user status and it as proper and improper. It also provides statistics to user about his/her posture and prevents user from improper alignment.

This paper presents a mathematical model that can be used to virtually reconstruct the posture of the human spine. By using orientation angles from a wearable monitoring system based on inertial sensors, the model calculates and represents the curvature of the spine. Several hypotheses are taken into consideration to increase the model precision. An estimation of the postures that can be calculated is also presented. A non-invasive solution to identify the human back shape can help reducing the time needed for medical rehabilitation sessions. Moreover, it prevents future problems caused by poor posture.
Online Monitoring of Posture for Preventive Medicine Using Low-Cost Inertial Sensors
Wireless Mobile Communication and Healthcare: 7th International Conference, 2018
People in many professions suffer from low back pain (LBP) due to wrong movements. Although this is anticipated by occupational medicine, the quality of evidence is low, since little objective measurements about the spine position in daily-use exist. The paper presents an ultra-flat posture monitoring system based on low-cost acceleration sensors, which can be very efficiently be used to measure the posture of the spine. First experiments (lab-based and in daily-use) showed a deviation of approximately 1° with a low standard deviation. Innovation is the suitability for daily-use by sensors having a height of 2,5 mm that allow a seamless usage even during positions applying pressure to the back such a leaned sitting on a chair.
A Survey on sitting posture monitoring systems
2018 9th International Symposium on Signal, Image, Video and Communications (ISIVC), 2018
Spinal pain caused by the bad sitting posture can affect adults and young people. The slouching and leaning for long hours using computers and portable electronic devices is the main cause of the back problems. Recently, in order to prevent the spinal pain, sitting posture monitoring systems have been developed in the literature to assess the posture of a seated person in real-time and improve sitting posture. The purpose of this study is to review the recent posture monitoring systems. The review is based on a literature search in PubMed, IEEE Xplore and Science Direct. We studied the main characteristics of the posture monitoring systems, the used technologies to identify the posture changes over time and the systems limits. The posture systems are classified according to their sensing technologies. This paper can be a valuable source of recent reference for future research in the field of sitting posture monitoring systems.

Monitoring the posture of older persons using portable sensors while they carry out daily activities can facilitate the process of generating indicators with which to evaluate their health and quality of life. The majority of current research into such sensors focuses primarily on their functionality and accuracy, and minimal effort is dedicated to understanding the experience of older persons who interact with the devices. This study proposes a wearable device to identify the bodily postures of older persons, while also looking into the perceptions of the users. For the purposes of this study, thirty independent and semi-independent older persons undertook eight different types of physical activity, including: walking, raising arms, lowering arms, leaning forward, sitting, sitting upright, transitioning from standing to sitting, and transitioning from sitting to standing. The data was classified offline, achieving an accuracy of 93.5%, while overall device user perception was positive. Participants rated the usability of the device, in addition to their overall user experience, highly.

To measure the curvature of the lumbar spine is an important challenge in disciplines related to Physical Therapy, Rehabilitation and Sports Medicine seeking to solve the incidence of the low back pain and other spinal disorders in population. In clinical practice, most of the methods used are manual or depend on the trained eye of the specialist who is measuring. We have developed Lumbatex: an integrated system based on inertial sensors integrated in a wearable textile device. This device is connected via Bluetooth to a software which interprets data from the sensors and provide real-time biofeedback to users in a graphical way and also a quantitative measure of the curvature and spinal motion. The system is tested in two ways: first, checking the accuracy detecting changes in curvatures; second, evaluating the usability and comfort from the user standpoint. The accuracy is checked through a static method getting curvature values from the device placed on curved platforms and a dynamic validation with volunteers performing different exercises. The results obtained showed a high accuracy measuring changes in curvature with an error lower than one degree in the static test, and a good usability and comfort according to the opinion of the volunteers.
