Download or read book Real Time Event Detection and Control of a Smart Knee Brace for Gait Rehabilitation written by Joseph Paul White and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Early gait rehabilitation training in stroke patients, often beginning within days of the stroke, is considered a promising method to correct hemiplegic gait patterns. Delaying the training may produce further impairments that can lead to joint damage and lessen the patient's quality of life. This work presents a Smart Knee Brace (SKB) that has been developed and refined to not only allow a physical therapist to pursue early gait rehabilitation in a patient, but also provides a flexible platform from which to develop effective rehabilitation methods with biofeedback. This thesis contains a description and discussion of the physical hardware, the sensors and electronics, and the software implemented in the SKB system. The current system includes a locking mechanism for both the flexion and extension directions of knee motion. The locks may be used to induce proper knee motion and muscle use as well as to prevent the patient's knee from collapsing in flexion. There are various sensors to provide kinematic data about the motion of the leg which are used to control this locking mechanism. The real time control of the system is made possible by customized software developed in Matlab and Simulink using the XPC Toolbox. The real time algorithm behind the control software is based solely on the kinematic data retrieved from the sensors on the SKB and was evaluated on a healthy patient wearing the SKB and through simulation with previously taken stroke patient data. It is shown to accurately detect the initial contact and toe off gait events.

Book excerpt: A real-time gait event detection algorithm was developed based solely on kinematic sensors on the brace as an alternative to footswitches. The current algorithm has advantages over footswitches that tend to be inaccurate, failure prone, and inconvenient for the standalone brace. The algorithm was applied to a healthy subject and to two stroke patients and was shown to accurately detect initial contact and toe off gait events.
Download or read book Automatic Detection and Recognition of Rehabilitative Activities Using a Smart Knee Brace written by Arran Davis and published by . This book was released on 2019 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anterior Cruciate Ligament Reconstruction (ACLR) is a knee surgery commonly required by athletes who sustain injury during sport. The rehabilitation process following surgery can take up to 24 months, involving regular contact with a physiotherapist in addition to digilent completion of rehabilitative protocols. Recent advances in wearable technologies, such as those supplied by OPUM, provide an opportunity to augment the decision making process of physiotherapists and aid in patient recovery. This focus in this project is to use the OPUM Digital Knee Brace, a smart knee orthosis, to produce a real time human activity recognition (HAR) system which automatically reports the completion of rehabilitation tasks performed by ACLR patients. As a secondary focus we are also interested in comfort experienced by subjects wearing the OPUM Device. In this work we construct our own dataset using the Digital Knee Brace and evaluate its performance on a number of different Machine Learning Algorithms. We take the most promising of these algorithms, Random Forest, and perform a novel compression method to optimize it for our real time system. Initially Random Forest classifies our tasks accurately with an F-Measure of 96.1%. Following compression we were able to reduce the size of our Random Forest by 98%, with a 1.6% reduction in F-Measure, and 99%, with a 3% reduction in F-Measure. These findings indicate that high performance HAR can be performed using the OPUM Digital Knee Brace.

Available in PDF, EPUB and Kindle. Book excerpt: The advances in the technology and methodology for human movement capture and analysis over the last decade have been remarkable. Besides acknowledged approaches for kinematic, dynamic, and electromyographic (EMG) analysis carried out in the laboratory, more recently developed devices, such as wearables, inertial measurement units, ambient sensors, and cameras or depth sensors, have been adopted on a wide scale. Furthermore, computational intelligence (CI) methods, such as artificial neural networks, have recently emerged as promising tools for the development and application of intelligent systems in motion analysis. Thus, the synergy of classic instrumentation and novel smart devices and techniques has created unique capabilities in the continuous monitoring of motor behaviors in different fields, such as clinics, sports, and ergonomics. However, real-time sensing, signal processing, human activity recognition, and characterization and interpretation of motion metrics and behaviors from sensor data still representing a challenging problem not only in laboratories but also at home and in the community. This book addresses open research issues related to the improvement of classic approaches and the development of novel technologies and techniques in the domain of motion analysis in all the various fields of application.

Download or read book Selected Health Conditions and Likelihood of Improvement with Treatment written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-07-12 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Social Security Administration (SSA) administers two programs that provide disability benefits: the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. SSDI provides disability benefits to people (under the full retirement age) who are no longer able to work because of a disabling medical condition. SSI provides income assistance for disabled, blind, and aged people who have limited income and resources regardless of their prior participation in the labor force. Both programs share a common disability determination process administered by SSA and state agencies as well as a common definition of disability for adults: "the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." Disabled workers might receive either SSDI benefits or SSI payments, or both, depending on their recent work history and current income and assets. Disabled workers might also receive benefits from other public programs such as workers' compensation, which insures against work-related illness or injuries occurring on the job, but those other programs have their own definitions and eligibility criteria. Selected Health Conditions and Likelihood of Improvement with Treatment identifies and defines the professionally accepted, standard measurements of outcomes improvement for medical conditions. This report also identifies specific, long-lasting medical conditions for adults in the categories of mental health disorders, cancers, and musculoskeletal disorders. Specifically, these conditions are disabling for a length of time, but typically don't result in permanently disabling limitations; are responsive to treatment; and after a specific length of time of treatment, improve to the point at which the conditions are no longer disabling.
