The article describes the main approaches to the use of modular training systems intended for NSTU students laboratory works in physics. Applying these systems is assumed in educating of schoolchildren to project research activity. Examples of laboratory equipment application during physical experiments performed by students of specialized classes are demonstrated.
A novel technique for intrusion detection is proposed in this paper, that is based on cutting-based real-valued negative selection scheme. Different from the current typical techniques, the proposed one sets a much more strict and reasonable mechanism to generate and optimize the set of mutual detector. Firstly, the new generating detector must be necessary and it should not be detected by the current...
Activity recognition is a key problem in multi-sensor systems. In a home-like environment, from several sensors of different types, the multi-sensor system identifies activities performed by the inhabitants. Many supervised learning techniques exist for solving this problem. In this paper, we present a novel argumentation based approach that seamlessly combines low level sensor data processing, realized...
This study has developed a device and system for the exercise of eccentric contraction of the tibialis anterior, with the objective of maintaining ambulatory function. A system was built that allows for exercises of appropriate load and speed, by providing the trainee with force data in the form of visual feedback. An experimental verification with two healthy participants shows small variation in...
In myoelectric prosthetic control, the motion classification performance would be decayed if an electromyography (EMG) pattern to be recognized differs significantly from the one used for classifier training. Generally, the training signals are acquired when a subject performs motions with a proper force. In practical use of a myoelectric prosthesis, however, the variation of force levels to do a...
Vertebral compression fractures are treated surgically for approximately 25 years. In percutaneous cement augmentation techniques bone cement is applied to a fractured vertebra under fluoroscopic evidence to stabilize the bone fragments. Complications due to leakage of the low viscosity bone cement are reported in 5 to 15% of all routine cases. During the intraoperative application of bone cement...
Puncturing the epidural space and lumbar puncture are common procedures in anesthesia. They are carried out blind, where a needle is advanced from posterior between two adjacent vertebrae. Two different approaches are common practice for this technique, the midline and the paramedian one. The learning curve characteristics of both approaches significantly depends on the number of punctures carried...
Following stroke, rehabilitation exercises paired with medical treatment are important for the recovery and maintenance of upper limb function. We developed a 2-DOF passive haptic system for upper limb rehabilitation and software focusing on reaching exercises, known as the coin collecting program, which provides training and evaluation of motor function, particularly dexterity. Past studies have...
Previous results suggest that haptic guidance enhances learning of the timing components of motor tasks, whereas error amplification is better for learning the spatial components. In this paper we evaluate a novel mixed guidance controller that combines haptic guidance and error amplification to simultaneously promote learning of the timing and spatial components. The controller is realized using...
We aimed to study the effects of an anti-gravity treadmill (AlterG) training on balance and postural stability in children with cerebral palsy (CP). AlterG training was performed 3 days/week for 8 weeks, with up to 45 minutes of training per session. The subject was evaluated before and after the 8-week training. The effects of training on the balance and postural stability was evaluated based on...
Physical interaction between man and machines is increasing the interest of the research as well as the industrial community. It is known that physical coupling between active persons can be beneficial and increase the performance of the dyad compared to an individual. However, the factors that may result in performance benefits are still poorly understood. The aim of this work is to investigate how...
Postural instability affects a large number of people and can compromise even simple activities of the daily routine. Therapies for balance training can strongly benefit from auxiliary devices specially designed for this purpose. In this paper, we present a system for balance training that uses the metaphor of a game, what contributes to the motivation and engagement of the patients during a treatment...
Simultaneous and proportional control of hand and wrist prostheses based upon surface electromyography (myocontrol) is still largely an open issue in the community of assistive robotics. It entails the ability of discriminating the activation levels for each degree of freedom (DOF) of the hand/wrist complex, using as few sensors as possible. Furthermore, one should avoid having the human subject train...
With the developments of robotics, more and more rehabilitation robots are used to assist traditional training in rehabilitation field. In this paper, a novel ankle robot combined with 3 degrees of freedom, full fill passive-active training, subjective awareness and objective training requirements was proposed. The requirement of ankle robot was analyzed based on the ankle physical structure and real...
Rehabilitation robots have been widely used in clinical rehabilitation in stroke subjects. The safety and comfort in rehabilitation training still are affected by many problems, however, such as the single rehabilitation training mode, the poor human-robot interaction and adaptability. In this paper, an adaptive trajectory planning method of lower limb rehabilitation robot based on surface Electromyography...
This paper proposed a VR-based self-rehabilitation system which utilizes the virtual training model rendered by OpenGL and collects electromyography (EMG) signals from the subjects to perform hand motion recognition. EMG signals are biomedical signals generated in muscles and can be applied in many fields such as clinical diagnosis and biomedical applications. The subjects were asked to manipulate...
Physical rehabilitation training using an intelligent control system is important for the people with lower limb dysfunction. In this paper, the sit-to-stand (STS) trajectory of health persons is researched based on STS biomechanics model. Several novel mechanical structures for intelligent lower limb STS rehabilitation training system are presented. According to the mechanical analysis of its finite...
This paper proposed a novel muscle force evaluation method to evaluate the patient's rehabilitation condition in the process of rehabilitation training. According to the related literature research, the complexity of the electromyography (EMG) signals were different under different muscle force. The physiological features and the state of muscle can be indirectly speculated by detecting the change...
Connected healthcare devices, including medical equipments as well as personal health devices based on emerging mobile technologies used by healthcare providers and consumers, are expanding traditional means of practicing healthcare particularly physiotherapy services. We describe a system based on physiotherapy smart connected devices, as smart walker, smart crutches, force platform and natural user...
After-stroke rehabilitation of patients with shoulder disabilities traditionally requires repeated and progressive training exercises. Complete recovery is usually costly and lengthy. Aimed at reducing the cost and time of shoulder rehabilitation, powered exoskeletons are developed to provide automatic and steady rehabilitation training. Our previously developed shoulder exoskeleton is small-size,...
