Abstract

Purpose

The purpose of this paper is to model and predict suitable gait trajectories of lower-limb exoskeleton for wearer during rehabilitation walking. Lower-limb exoskeleton is widely used for assisting walk in rehabilitation field. One key problem for exoskeleton control is to model and predict suitable gait trajectories for wearer.

Design/methodology/approach

In this paper, the authors propose a Deep Spatial-Temporal Model (DSTM) for generating knee joint trajectory of lower-limb exoskeleton, which first leverages Long-Short Term Memory framework to learn the inherent spatial-temporal correlations of gait features.

Findings

With DSTM, the pathological knee joint trajectories can be predicted based on subject’s other joints. The energy expenditure is adopted for verifying the effectiveness of new recovery gait pattern by monitoring dynamic heart rate. The experimental results demonstrate that the subjects have less energy expenditure in new recovery gait pattern than in others’ normal gait patterns, which also means the new recovery gait is more suitable for subject.

Originality/value

Long-Short Term Memory framework is first used for modeling rehabilitation gait, and the deep spatial–temporal relationships between joints of gait data can obtained successfully.

Abstract

Purpose

Traumatic brain injuries (TBIs) are a significant public health problem that affect an estimated 1.7 million US residents yearly. TBI patients experience a variety of symptoms related to physical functioning, sensory processing, cognition, communication, behavior, and mental health, all of which differ in severity by individual. Recent evidence suggests that hypothalamic pituitary dysfunction may be impacting recovery. The purpose of this paper is to increase awareness about the frequency of hypothalamic pituitary dysfunction following a TBI and its effect on functional recovery.

Design/methodology/approach

The paper reviews the literature regarding hypothalamic pituitary dysfunction following TBI and discusses the potential benefits of hormone replacement therapy for individuals with hormone deficiencies.

Findings

The rate of hypothalamic pituitary dysfunction following TBI has been reported as anywhere between 25 and 80 percent. Specifically, abnormal hormone levels, both chronic and acute, are generally estimated to be approximately 5-22 percent for thyroid hormones, 15-33 percent for growth hormone (GH), and 25-80 percent for testosterone. The effect of hypopituitarism has been reported on several aspects cognitive and physical function as well as overall quality of life. In these studies, GH and testosterone deficiencies appear to underlie the observed impairments.

Originality/value

The paper suggests the importance of understanding and screening for hypothalamic pituitary dysfunction as hormone replacement therapy may be a beneficial intervention to promote physical and cognitive rehabilitation.

Abstract

Purpose

The purpose of this study is to see whether the figure of eight walkings (F8W) is a reliable outcome measure in rehabilitation care especially for the older population who need extensive consideration in their practical functional affairs.

Design/methodology/approach

The literature review was conducted by researching various databases such as Google Scholar, Pub Med and Web of Science, Scopus. Journals with Good impact factors were included in this study.

Findings

This review suggested that F8W could be the realistic outcome measure for rehabilitation in patients with musculoskeletal and neurological dysfunctions that could identify disability and functional impairments more deeply. Future studies in this field may provide further exploration in physiotherapy rehabilitation.

Research limitations/implications

The study was a short review with limited resources. Its’ findings and outputs must be considered prelusive.

Practical implications

The accustomed routine of manhood accounts for constant twists and turns which is entirely incompatible with a linear walk. In such a manner, walking in the figure of eight could detect the major perplexity faced by an individual in his habitual pursuing affairs predominately in orthopedics and neurological disorders.

Originality/value

The study has suggested the utility of F8W as a reliable tool in the rehabilitation of the elder population, evidence suggests, F8W constitutes curvy and straight paths, which could trace troubles while turning and maintaining coordination. These results of this study can serve as a foundation for future studies.

Abstract

Purpose

This research was to understand people's perceptions and trends in wearable robots and the research questions were as follows: (1) investigating key terms related to wearable robots that were frequently used by and exposed to people and (2) analyzing relationships among those key terms.

Design/methodology/approach

Textom, a big data collection and analysis software system, was used to collect data using the keyword – wearable robot.

Findings

The frequency-inverse document frequency, term frequency and central analyses were investigated, and the major key terms related to wearable robots and their connectivity were identified. After performing network analysis and convergence of iterated correlations analyses using UCINET and NetDraw programs, the major key term categories were identified.

Originality/value

It is important to understand how people think and perceive about wearable robots before developing wearable robots. The results of the research are expected to be helpful to better understand how people perceive and what key terms are mainly discussed by people in both countries and ultimately help when developing wearable robots with better market targeting approach methods.

Abstract

Purpose

The purpose of this paper is to evaluate three categories of four-degrees of freedom (4-DOFs) upper limb rehabilitation exoskeleton mechanisms from the perspective of relative movement offsets between the upper limb and the exoskeleton, so as to provide reference for the selection of exoskeleton mechanism configurations.

Design/methodology/approach

According to the configuration synthesis and optimum principles of 4-DOFs upper limb exoskeleton mechanisms, three categories of exoskeletons compatible with upper limb were proposed. From the perspective of human exoskeleton closed chain, through reasonable decomposition and kinematic characteristics analysis of passive connective joints, the kinematic equations of three categories exoskeletons were established and inverse position solution method were addressed. Subsequently, three indexes, which can represent the relative movement offsets of human–exoskeleton were defined.

Findings

Based on the presented position solution and evaluation indexes, the joint displacements and relative movement offsets of the three exoskeletons during eating movement were compared, on which the kinematic characteristics were investigated. The results indicated that the second category of exoskeleton was more suitable for upper limb rehabilitation than the other two categories.

Originality/value

This paper has a certain reference value for the selection of the 4-DOFs upper extremity rehabilitation exoskeleton mechanism configurations. The selected exoskeleton can ensure the safety and comfort of stroke patients with upper limb dyskinesia during rehabilitation training.

Abstract

Acute and chronic pain affects more Americans than heart disease, diabetes, and cancer combined. Conservative estimates suggest the total economic cost of pain in the United States is $600 billion, and more than half of this cost is due to lost productivity, such as absenteeism, presenteeism, and turnover. In addition, an escalating opioid epidemic in the United States and abroad spurred by a lack of safe and effective pain management has magnified challenges to address pain in the workforce, particularly the military. Thus, it is imperative to investigate the organizational antecedents and consequences of pain and prescription opioid misuse (POM). This chapter provides a brief introduction to pain processing and the biopsychosocial model of pain, emphasizing the relationship between stress, emotional well-being, and pain in the military workforce. We review personal and organizational risk and protective factors for pain, such as post-traumatic stress disorder, optimism, perceived organizational support, and job strain. Further, we discuss the potential adverse impact of pain on organizational outcomes, the rise of POM in military personnel, and risk factors for POM in civilian and military populations. Lastly, we propose potential organizational interventions to mitigate pain and provide the future directions for work, stress, and pain research.

Abstract

Summarises the environmental cadmium loading, human body cadmium (Cd) burden and the biological indicators of the early‐stage health effects induced by exposure to cadmium on the population of Daye county in China. Claims that urinary calcium and urinary low molecular weight protein are good biological indicators for the detection of the early‐stage renal dysfunction and recommend that the prevention and treatment of cadmium pollution be incorporated into primary health care. Cost‐benefit analysis of reduction of Cd emissions from the non‐ferrous smelter in Daye county indicates that the benefit‐cost ratio taking into account both direct health costs and indirect costs is far in excess of unity.

Abstract

A variety of brain pathologies can result in difficulties performing complex behavioural sequences. Assistive technology for cognition (ATC) attempts support of complex sequences with the aim of reducing disability. Traditional ATCs are cognitively demanding to use and thus have had poor uptake. A more intuitive interface may allow ATCs to reach their potential. Insights from psychological science may be useful to technologists in this area. We propose that an auditory‐verbal interface is more intuitive than a visual interface and reduces cognitive demands on users. Two experiments demonstrate a novel ATC, the General User Interface for Disorders of Execution (GUIDE). GUIDE is novel because it simulates normal conversational prompting to support task performance. GUIDE provides verbal prompts and questions and voice recognition allows the user to interact with the GUIDE. Research with non‐cognitively impaired participants and a single participant experiment involving a person with vascular dementia provide support for using interactive auditory‐verbal interfaces. Suggestions for the future development of auditory‐verbal interfaces are discussed.
