Humidity Adaptive Antifreeze Hydrogel Sensor for Intelligent Control and Human-Computer Interaction.

Conductive hydrogels have emerged as ideal candidate materials for strain sensors due to their signal transduction capability and tissue-like flexibility, resembling human tissues. However, due to the presence of water molecules, hydrogels can experience dehydration and low-temperature freezing, which greatly limits the application scope as sensors. In this study, an ionic co-hybrid hydrogel called PBLL is proposed, which utilizes the amphoteric ion betaine hydrochloride (BH) in conjunction with hydrated lithium chloride (LiCl) thereby achieving the function of humidity adaptive. PBLL hydrogel retains water at low humidity (<50%) and absorbs water from air at high humidity (>50%) over the 17 days of testing. Remarkably, the PBLL hydrogel also exhibits strong anti-freezing properties (-80°C), high conductivity (8.18 Sm-1 at room temperature, 1.9 Sm-1 at -80°C), high gauge factor (GF approaching 5.1). Additionally, PBLL hydrogels exhibit strong inhibitory effects against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), as well as biocompatibility. By synergistically integrating PBLL hydrogel with wireless transmission and Internet of Things (IoT) technologies, this study has accomplished real-time human-computer interaction systems for sports training and rehabilitation evaluation. PBLL hydrogel exhibits significant potential in the fields of medical rehabilitation, artificial intelligence (AI), and the Internet of Things (IoT).

A Combination Model of Shifting Joint Angle Changes With 3D-Deep Convolutional Neural Network to Recognize Human Activity.

Research in the field of human activity recognition is very interesting due to its potential for various applications such as in the field of medical rehabilitation. The need to advance its development has become increasingly necessary to enable efficient detection and response to a wide range of movements. Current recognition methods rely on calculating changes in joint distance to classify activity patterns. Therefore, a different approach is required to identify the direction of movement to distinguish activities exhibiting similar joint distance changes but differing motion directions, such as sitting and standing. The research conducted in this study focused on determining the direction of movement using an innovative joint angle shift approach. By analyzing the joint angle shift value between specific joints and reference points in the sequence of activity frames, the research enabled the detection of variations in activity direction. The joint angle shift method was combined with a Deep Convolutional Neural Network (DCNN) model to classify 3D datasets encompassing spatial-temporal information from RGB-D video image data. Model performance was evaluated using the confusion matrix. The results show that the model successfully classified nine activities in the Florence 3D Actions dataset, including sitting and standing, obtaining an accuracy of (96.72 ± 0.83)%. In addition, to evaluate its robustness, this model was tested on the UTKinect Action3D dataset, obtaining an accuracy of 97.44%, proving that state-of-the-art performance has been achieved.

Patients who utilise sensor-based devices have several advantages due to rehabilitating a missing component, which marks the accomplishment of a fundamental goal within the rehabilitation program. As technology moves faster and faster forward, the field of medical rehabilitation has to adapt to the time we live in by using technology and intelligent devices. This means changing every part of rehabilitation and finding the most valuable and helpful gadgets that can be used to regain lost functions, keep people healthy, or prevent diseases.

Актуальные вопросы организации профессиональной переподготовки специалистов по физической реабилитации (кинезиоспециалистов) в условиях новой модели медицинской реабилитации.

The system of medical rehabilitation in Russia undergoes significant transformation which is reflected in the Federal Program «Optimal for health restoration medical rehabilitation in the Russian Federation». In such situation the issues of personnel training in the field of medical rehabilitation are becoming extremely relevant. The difficulties that arise along this path are associated with the interdisciplinarity of medical rehabilitation and the necessity to train specialists with medical education (doctors and nurses) as well as with higher non-medical education: physical therapists, ergotherapists, medical psychologists and medical speech therapists (according to the Order No. 788n of 31.07.2020). These allied health specialties are new for Russia but they are responsible for the main practical activity in the implementation of an individual medical rehabilitation plan. The difficulties in training non-medical personnel in rehabilitation largely arise from the requirement for them to have both medical and pedagogical competencies and to have the ability to work independently as well as in a rehabilitation team. This article summarizes the three-year experience of training specialists in medical rehabilitation with higher non-medical education at the National Research Nizhny Novgorod State University named after N. I. Lobachevsky. The article presents the main issues of the professional retraining program «Physical rehabilitation (physical therapy)» with a duration of 1020 hours, defines professional competencies, difficult issues of training, formation of practical skills and assessment of professional competencies in this category of students.

Aloe Inspired Special Structure Hydrogel Pressure Sensor for Real‐Time Human‐Computer Interaction and Muscle Rehabilitation System

AbstractIn recent years, significant progress has been made in the research and development of conventional hydrogel sensors. However, the development of hydrogels with special structures, achieved through specific designs or fabrication strategies, remains relatively scarce. Inspired by aloe, a specially structured hydrogel (named Skin‐Polyvinyl alcohol‐Polyaniline‐AgNWs, S‐PPA) is successfully prepared with skin. Innovatively utilizing the hydrogen bonding interaction between ions and water molecules, the surface of the hydrogel is treated to create a protective skin. The S‐PPA hydrogel with a protective skin demonstrates strong resistance to damage (with a tensile strength of 5 MPa, &gt;11 times higher compared to hydrogel without skin) and exhibits dual conductivity (0.8 S m−1 for the inner skin and 0.33 S m−1 for the outer skin). In addition, the S‐PPA hydrogel also possesses water retention capabilities, antibacterial properties (89.4% inhibition rate against Staphylococcus aureus (S. aureus)), and minimal corrosion to metal electrodes. Based on the S‐PPA hydrogel and combined with wireless Bluetooth technology and Python programming, intelligent applications are developed such as multi‐gradient intelligent control and finger muscle condition evaluation, achieving real‐time human‐ computer interaction (HCI). The intelligent pressure‐sensitive hydrogel proposed by this study shows great potential in the fields of medical rehabilitation, artificial intelligence, and the Internet of Things.

Rehabilitation exoskeleton torque control based on PSO-RBFNN optimization.

Exoskeletons are widely used in the field of medical rehabilitation, however imprecise exoskeleton control may lead to accidents during patient rehabilitation, so improving the control performance of exoskeletons has become crucial. Nevertheless, improving the control performance of exoskeletons is extremely difficult, the nonlinear nature of the exoskeleton model makes control particularly difficult, and external interference when the patient wears an exoskeleton can also affect the control effect. In order to solve the above problems, a method based on particle swarm optimization (PSO) and RBF neural network to optimize exoskeleton torque control is proposed to study the motion trajectory of nonlinear exoskeleton joints in this paper, and it is found that exoskeleton torque control optimized by PSO-RBFNN has faster control speed, better stability, more accurate control results and stronger anti-interference, and the optimized exoskeleton can effectively solve the problem of difficult control of nonlinear exoskeleton and the interference problem when the patient wears the exoskeleton.

Control strategy based on improved fuzzy algorithm for energy control of wrist rehabilitation robot

With the complex changes in social and demographic structure, the problem of aging is becoming increasingly serious, and the demand for equipment in the field of medical rehabilitation is also increasing. Given the above situation, various countries have proposed using rehabilitation robots to assist patients in treatment, and have achieved certain results. The rehabilitation robot helps the injured area gradually recover autonomous movement through repeated auxiliary actions, thereby achieving the goal of physical rehabilitation training. However, most robot configurations face insufficient energy and power, as well as bulky and inflexible equipment. Based on the above issues, this article adopts an improved fuzzy algorithm control strategy to optimize the energy storage device and applies the energy system to the wrist rehabilitation training robot device. Firstly, a fuzzy adaptive algorithm is added to the traditional energy controller to combine system control with operational status, achieving precise control and dynamic adjustment of energy allocation. The research has added filter optimization design, which improves the accuracy and effectiveness of fuzzy algorithms. Finally, this article establishes an upper limb motion model of the rehabilitation robot and configures relevant hardware systems. At the same time, this article also uses manufacturing materials that meet functional requirements to construct auxiliary equipment. The results indicate that the improved fuzzy algorithm can improve the auxiliary effect in energy control of wrist rehabilitation robots. It has obvious advantages in the process of wrist rehabilitation training.

A Multi-Label Based Physical Activity Recognition via Cascade Classifier.

Physical activity recognition is a field that infers human activities used in machine learning techniques through wearable devices and embedded inertial sensors of smartphones. It has gained much research significance and promising prospects in the fields of medical rehabilitation and fitness management. Generally, datasets with different wearable sensors and activity labels are used to train machine learning models, and most research has achieved satisfactory performance for these datasets. However, most of the methods are incapable of recognizing the complex physical activity of free living. To address the issue, we propose a cascade classifier structure for sensor-based physical activity recognition from a multi-dimensional perspective, with two types of labels that work together to represent an exact type of activity. This approach employed the cascade classifier structure based on a multi-label system (Cascade Classifier on Multi-label, CCM). The labels reflecting the activity intensity would be classified first. Then, the data flow is divided into the corresponding activity type classifier according to the output of the pre-layer prediction. The dataset of 110 participants has been collected for the experiment on PA recognition. Compared with the typical machine learning algorithms of Random Forest (RF), Sequential Minimal Optimization (SMO) and K Nearest Neighbors (KNN), the proposed method greatly improves the overall recognition accuracy of ten physical activities. The results show that the RF-CCM classifier has achieved 93.94% higher accuracy than the 87.93% obtained from the non-CCM system, which could obtain better generalization performance. The comparison results reveal that the novel CCM system proposed is more effective and stable in physical activity recognition than the conventional classification methods.

Digital twin rehabilitation system based on self-balancing lower limb exoskeleton.

The digital twin concept is the virtual model based on entity design measures, which is used in many enterprises' virtual workshop design models for workshop production scheduling and optimization. However, in the field of medical rehabilitation, the integration of digital twin technology started late compared to traditional industrial manufacturing. Many current digital models are not well suited for information interaction between patients and devices. In order to address the lack of interaction between patients and devices in the field of medical rehabilitation, this paper proposes an automatic gait data control system (AGDCS) for fully actuated lower limb exoskeleton digital twinning. This system improves the integration of digital twinning system with the medical rehabilitation field and analyzes the patient's gait data through simulation experiments. The digital twin system was designed in several steps. Firstly, the upper computer function module was designed and developed according to the rehabilitation treatment needs. After that, the combination of exoskeleton robot and software was carried out, and finally the real rehabilitation treatment environment of patients was simulated through experiments. The proposed system was very reliable in the experimental tests of the host computer and exoskeleton robot. In the upper computer test, the patient specific gait can be generated, and the motion of the exoskeleton robot can be observed in real-time. During the walking test of the exoskeleton robot, the exoskeleton robot completed the specified gait. The result verified the superiority and effectiveness of the digital twin system AGDCS in the field of rehabilitation. The digital twin system proposed in this paper improves the interaction between self-balancing exoskeleton robot and patients, and improves the autonomy and safety of patients in rehabilitation treatment.

Personal‐specific gait recognition based on latent orthogonal feature space

Exoskeleton has been applied in the field of medical rehabilitation and assistance. However, there are still some problems in the interaction between human and exoskeleton, such as time delay, the existence of certain constraints on the human body, and the movement in time is hard to follow. A human motion pattern recognition model based on the long short-term memory (LSTM) is proposed, which can recognise the state of the human body. Meanwhile, the orthogonalisation method is integrated to make personal-specific disentangling, and it can effectively improve the generalisation ability of different groups of people, so as to improve the effective follower ability of the exoskeleton. Compared with some other traditional methods, this model has better performance and stronger generalisation ability, which has certain significance in the field of exoskeleton algorithm.

I ntelligent Information Systems (IIS) is the next step in the evolution of information processing systems. The intelligent system must provide the opportunity to use modern technologies and tools for data integration, their processing and extraction of knowledge in explicit or implicit form. The use of ontologies is provided an eff ective analysis of information resources and their use in IIS, especially in areas of human activity that are evolving and changing rapidly. The implementation of an eff ective rehabilitation system based on evidence-based medicine and uniform standards and rules is an important component of Ukraine’s health care system in the time of a pandemic. Subject orientation of the transdisciplinary intellectual information-analytical system and creation of separate functional confi gurations of the system is aimed at use in the fi eld of medical rehabilitation. Objective of the research was the subject orientation of the transdisciplinary intellectual information-analytical system and the creation of individual functional confi gurations of the system for use in the fi eld of medical rehabilitation. The theoretical and methodological basis of “Transdisciplinary intelligent information and analytical system for the rehabilitation processes support in a pandemic (TISP)” is the conceptual and methodological principles of knowledge-oriented processing of natural language texts. They consist of models and methods that include methods of construction and processing of ontologies of the subject area, which are based on methods of construction and analysis of the structure of growing pyramidal networks; logical-mathematical models of natural language texts processing on the basis of ontologies and growing pyramidal networks; local-statistical method of concept allocation in growing pyramidal networks, which allows forming the concepts of minimum length with maximum support for polynomial time; methods of semantic processing of natural language texts, which use the mechanisms of adjacency of facts, to form a system of «questions and answers» on the content of texts. In the process of performing the grant work, a strategy for expanding the functionality and subject orientation of TISP was developed. TISP platform was implemented with a component architecture of cognitive services, which provides transdisciplinary consolidation of all specialists who need to be involved in the rehabilitation of a particular patient. The International Classifi cation of Functioning, Disability and Health, (ICF) and the White Book on Physical and Rehabilitation Medicine in Europe, which defi nes the nature, scope and parameters of physical and rehabilitation medicine in Europe, have been developed in the form of interactive documents. The ontology-driven approach to the operability of the interaction between the doctor-rehabilitation specialist and the patient promptly implements the entire technological chain from determining the patient’s condition to the choice and appointment by the doctor of a specifi c set of rehabilitation procedures. The use of an ontology-driven approach provides fl exibility in the subject orientation of TISP and the building of individual functional confi gurations of the system.
