A Novel Human-Machine Collaboration Model of an Ankle Joint Rehabilitation Robot Driven by EEG Signals

With the emergence of the phenomenon of social aging, the elderly have frequent physical movement disorders. In particular, the movement disorder of the ankle joint seriously affects the daily life of the elderly. Rehabilitation robots are of great significance for improving the efficiency of rehabilitation, ensuring the quality of rehabilitation, and reducing the labor intensity of workers. As an auxiliary treatment tool, rehabilitation robots should have rich and effective motion modes. The exercise mode should be adaptable for patients with different conditions and different recovery periods. To improve the accuracy of human-computer interaction of ankle joint rehabilitation robots (AJRR), this study proposes a man-machine collaboration model of an EEG-driven AJRR. The model mainly expands from two levels (1) to establish the connection between EEG and intention so as to identify the intention. In the recognition process, first feature extraction is given on the preprocessed EEG. Convolutional neural network (CNN) is selected to extract the deep features of the EEG signal, and support vector machine (SVM) is used for classifying the deep features, thereby realizing intent recognition. (2) The result of intention recognition is input to the human-computer interaction (HCI) system, which controls the movement of the rehabilitation robot after receiving the instruction. This study truly realizes patient-oriented rehabilitation training. Experiments show that the human-machine collaboration model used can show higher accuracy of intention recognition, thereby increasing the satisfaction of using AJRR.

Motion simulation of Bionic Auxiliary Device for Ankle Rehabilitation based on small driving moment function

A kind of auxiliary device for ankle rehabilitation based on a ball pin vice is introduced in this paper first. The device has two degrees of freedom, while three-dimensional movement of the ankle can be achieved approximately. The modeling and simulation process of the ankle joint rehabilitation device are described in this paper. Motion simulation is preceded by using ADAMS for researching its dynamics and kinematics performance when the upper platform adopts small driving moment function to control the movement. The results are compared with the results of motion simulation driven by modified constant velocity function. The results show that the maximum driving torque of the motor driven by the small driving moment function is less than the maximum driving torque of the motor driven by the modified constant velocity function, which has a certain effect on saving energy consumption of the motor.

Development of on-line lateral stiffness measurement system for anterior cruciate ligament and its influence on anterior cruciate ligament reconstruction

The anterior cruciate ligament (ACL) reconstruction mostly relies on the experience of surgeons. To improve the effectiveness and adaptability of the tension after ACL reconstruction in knee joint rehabilitation, this paper establishes a lateral force measurement model with relaxation characteristics and designs an on-line stiffness measurement system of ACL. In this paper, we selected 20 sheep knee joints as experimental material for the knee joint stability test before the ACL reconstruction operation, which were divided into two groups for a comparative test of single-bundle ACL reconstruction through the anterolateral approach. The first group of surgeons carried out intraoperative detection with routine procedures. The second group used ACL on-line stiffness measurement system for intraoperative detection. After that, the above two groups were tested for postoperative stability. The study results show that the tension accuracy is (- 2.3 ± 0.04)%, and the displacement error is (1.5 ± 1.8)%. The forward stability, internal rotation stability, and external rotation stability of the two groups were better than those before operation ( P < 0.05). But the data of the group using the system were closer to the preoperative knee joint measurement index, and there was no significant difference between them ( P > 0.05). The system established in this paper is expected to help clinicians judge the ACL reconstruction tension in the operation process and effectively improve the surgical effect.

Lower Limb Joint Nursing and Rehabilitation System Based on Intelligent Medical Treatment.

With the aggravation of the problem of aging population, all kinds of lower limb paralysis caused by various diseases occur frequently. People's demand for lower limb nursing and rehabilitation treatment is growing. In this paper, combined with intelligent medical technology and lower limb kinematics model, this paper proposes to build a lower limb joint nursing and rehabilitation system based on intelligent medical treatment. It is expected that, through the following limb joint rehabilitation robot as the main rehabilitation means, a smart nursing rehabilitation system which can quickly respond to users and realize remote rehabilitation nursing can be designed. First of all, it is clear that the main body of the lower limb joint rehabilitation system consists of the robot body and the state display system. Then, the sensor, amplifier, and data acquisition card are set in the data acquisition system, and the plantar balance force is detected using a FlexiForce film pressure sensor. The final control system mainly includes the main control module program and the lower limb action recognition program. The motor control software adopts PID regulation method, and the lower limb action recognition adopts SVM one-to-one classification method. After the construction of lower limb joint nursing and rehabilitation system, the accuracy rate of action recognition and classification was tested. In the third experiment, the accuracy of all the movements was 100%. Then, the joint displacement and angle changes of the experimenter assisted by the system were analyzed. The experimenter's knee joint and hip joint show a normal walking state, and the joint angle changes tend to be normal. Ten out of 55 rehabilitation system users were randomly selected for interview survey. The total scores of operation convenience, wearing comfort, intensity suitability, and movement science of the system were 90, 83, 84, and 91, respectively. This shows that the rehabilitation action designed by the system is scientific and easy to operate and can be put into use in rehabilitation training after improving the wearing comfort.

Возможности применения обратной ходьбы при патологии коленного сустава (обзор литературы)

Introduction Recently backward/retro walking has been increasingly used in medicine. Kinetic and kinematic analysis during backward walking showed advantages over traditional ambulation making it ideal for those who struggle with knee pain. Retro walking is well known for reducing the strain on the knees and it is one of the few natural ways to strengthen the quadriceps of the thigh. Walking backwards leads to a more significant load on the cardiovascular and respiratory systems. This load builds a more substantial increase in both the aerobic and anaerobic capabilities than just walking forward with similar parameters of physical activity. Material and methods A systematic search of studies published during the period up to February 2020 was conducted using bibliographic databases in English, including Medline, PubMed, Scopus, Web of Science and in Russian, including eLIBRARY, CyberLeninka to summarize the available information on the possibilities of retro walking in treatment and rehabilitation of patients with knee pathology. Search terms included 'backward/retro walking/running', 'knee joint'. Results and discussion Several studies have been performed to explore the effectiveness of backward walking for knee osteoarthritis. There is a strong evidence that backward walking can be a useful adjunct to conventional physiotherapy to improve pain, knee function and strength of the quadriceps muscles. There is a limited number of papers describing effects of backward walking for patellofemoral pain syndrome and anterior cruciate ligament injury. Conclusions Although there is little data overall reporting effects of backward walking, and more studies are needed to further explore this topic this version of walking has been shown to provide great beneficial effects in knee joint rehabilitation.

Affordable Robotics for Upper Limb Stroke Rehabilitation in Developing Countries: A Systematic Review

Stroke incidence is increasing more rapidly in Low- and Middle-Income Countries (LMICs) than in High-Income Countries (HICs), but LMICs are not well organized to provide adequate post-stroke rehabilitation because of physical, financial and personal barriers. The use of rehabilitation robotics can help bridge in healthcare disparities but they are available in LMICs in limited number due to their high cost and this limits the number of patients that can benefit from them. This article presents a literature review on the affordable robots for upper limb stroke rehabilitation that could be suitable in low-resources clinical settings with a focus on the different techniques implemented to reduce production costs. Different approaches can be carried out: i) developing end-effector and exoskeleton robots for the rehabilitation of proximal and distal joints respectively; ii) reducing the number of degrees of freedom of the robots at minimum (one or two) allowing the rehabilitation in a planar workspace; iii) avoiding the use of conventional materials that could make the robot bulky, expensive and difficult to transport. According to the mechanical properties required by the task, stell or metal alloys could be substituted for wood, aluminum, plastic, 3D-printed materials and by the adaptation of off-the-shelf elements.

Smart Robotic Exoskeleton: a 3-DOF for Wrist-forearm Rehabilitation

In order to regain the activities of daily living (ADL) for patients suffering from different conditions such as stroke and spinal cord injury, they must be treated with rehabilitation process through programmed exercises. The human motor system can learn through motor learning. This study concerned with the rehabilitation of wrist and forearm joints to restore the ADL through designing and constructing a robotic exoskeleton. The exoskeleton was designed to rehabilitate the patients by providing a 3 degree of freedom (DOF) include flexion/ extension, adduction/abduction, and pronation/ supination movements. It is specified as being portable, comfortable, lightweight, and compatible with the human anatomical structure, in addition to providing a speed and range of motion (ROM) as that of a normal subject. It was designed with SolidWorks software program and constructed with a 3D printer technique using polylactic acid (PLA) plastic material. The overall exoskeleton was controlled with electromyography and angle information extracted using EMG myoware and gyroscope sensors respectively. it was applied for evaluation with 5 normal subjects and 12 subjects of stroke and spinal cord injury (SCI). The results were found that the exoskeleton has a strong effect on regaining muscle activity and increasing the ROMs of wrist and forearm joints. These results give proof of this exoskeleton to be used for performing physiotherapy exercises.

Optimized Design for Cable-Driven Shoulder-Elbow Exoskeleton Robot

The cable-driven exoskeletons have the advantages of low inertia and simple structure, and they are widely applied for human augmentation and rehabilitation. However, they have limited workspace and tension efficiency because of the unidirectional nature of the cables. The limited performance affects the human-robot interaction and leads to potential danger. The workspace and tension efficiency can be optimized by conventional methods, which are adjusting the cable attachment points and increasing the actuators. But the workspace still cannot cover the human joint space of activities of daily living, and the efficiency is also not high. This paper analyzed the specific application for shoulder and elbow joints rehabilitation and proposed a dynamic adaptive structure. This design can increase the workspace and improve tension efficiency greatly. The dynamic compensation control strategy is designed for the optimized system. Besides, in order to reduce the effects of compliant elements (e.g., cables or Bowden cables) between the actuators and output, and to improve the force bandwidth, we designed the distributed active semi-active system composed of the geared DC motor and magnetorheological clutches, which has low output inertia. The related experiments are carried out based on several healthy subjects. The results verified that the exoskeleton with the dynamic adaptive structure has a large workspace covering the activities of daily living joint space, high tension efficiency, and high force bandwidth, which is beneficial for the safety and comfort of human-robot interaction during rehabilitation training.

Function of the Distal Part of the Vastus Medialis Muscle as a Generator of Knee Extension Twitch Torque.

The distal part of the vastus medialis (VM) (VM obliquus: VMO) muscle acts as the medial stabilizer of the patella. However, it has been known to facilitate VMO contraction during training of the quadriceps femoris muscle in knee joint rehabilitation. This study aimed to examine the contribution degree of VMO as a knee joint extension torque generator. Sixteen healthy male volunteers participated in this study. Electrical muscle stimulation (EMS) was performed on VMO at 60° knee angle for 20 min to induce muscle fatigue. Knee extension twitch torques (TT) at 90° and 30° knee angle evoked by femoral nerve stimulation were measured before and after EMS. Although each TT at 90° and 30° knee angle significantly decreased after EMS, the decreased TT rate in both joint angles showed no significant difference. Our results show that VMO might contribute to the generation of the knee joint torque at the same level in the range from flexion to extension. Therefore, it was suggested that the facilitating the neural drive for VMO is important during the quadriceps femoris muscle strengthening exercise.

Influence of Kinesio tape on lower limb muscular activity after knee joint rehabilitation program

This study aimed to identify the effect of using Kinesio tape on the neuromuscular activity of quadriceps muscle after the rehabilitation program of the knee joint. Ten players participated in present study (age: 26.20 ± 1.69 years; body mass: 77.10 ± 4.48 kg; height: 172.30 ± 5.46 cm). The EMG signals were stored at a sampling frequency of 1000 Hz and digitized using a 16-bit analogue to digital (A/D) converter. EMG data were processed using ProEMG software (Myon 320, Schwarzenberg, Switzerland). Raw EMG data was band-pass (20 Hz- 450 Hz) applying a Butterworth filter. The signals were preprocessed using full-wave rectified and a linear envelope obtained using the Root Mean Square (RMS) approach with a window size of 300 ms. Data was normalised to the peak muscle activity value over each attempt (%MAX). Descriptive statistics were reported as means and standard deviations (mean ± Std. Deviation). The normality of the data was analyzed using the Shapiro-Wilk test. Independent T-test was used to detect significant differences and compare the mean of each variable between single-leg squat and balance tests. The statistical analysis was performed using IBM SPSS software Statistics v21 SPSS Inc., USA) with significance level defined as p < 0.05 for each test. The results of the present study showed that applying KT around the knee joint after rehabilitation program does not promote immediate changes or effects on the lower limb muscle activities of (VL, RF, VM, BF, ST, L_GAST, and M_GAST

Wearable Wrist Movement Monitoring Using Dual Surface-Treated Plastic Optical Fibers

Regarding high-sensitivity human wrist joint motion monitoring in exercise rehabilitation; we develop a pair of novel wearable and sensitivity-enhanced plastic optical fiber (POF) strain sensors consisting of an etched grating fiber and a side-polished fiber stitched into a polyamide wrist brace. The two flexible and surface-treated fibers are; respectively; featured with an etched periodic gratings with a pitch of 6 mm and a depth of 0.5 mm and a D-shaped side-polished zone of ~300 µm depth and ~30 mm length; which, correspondingly, show the sensitivities of around 0.0176/° and 0.0167/° in a normalized bending angle by far larger than a conventional commercial POF, because it achieves a more sensitive strain-induced evanescent field interaction with the side-machined fibers. Moreover, in terms of the sensor response to bending deformation in the range of −40°~+40°, the former exhibits a better sensitivity in lower angle change, while the latter is superior as the bending angle increases; thereby arranging the two modified POFs separately at the side and back of the human wrist, in order to decouple the wrist joint behaviors induced by typical flexion-extension or abduction-adduction movements. Then, the circular and pentagonal wrist motion trajectory patterns are investigated, to demonstrate the maximum average single-axis motion error of 2.94° via the transformation of spatial angle to plane coordinate for the fabricated couple of POF sensors, which is lower than a recognized standard of 5°, thus suggesting the great potential in wearable exercise rehabilitation of human joints in the field of medical treatment and healing.

A Novel Pantographic Exoskeleton Based Collocated Joint Design With Application for Early Stroke Rehabilitation

Motivated by the need to develop safe exoskeletons for collocated joint rehabilitation during the early stage of stroke recovery, this article presents a pantographic exoskeleton (PGE) capable of multi-degree-of-freedom motions in a single-joint collocated with the impaired joint. With minimum internal joint reactions in the presence of misalignment, the PGE “traces” the natural joint motion “like a pantograph” in the sagittal plane while performing in-bed rehabilitation, from which the joint parameters can be estimated for subsequent patient-specific motion training. An analytical model is presented to provide a rational basis for designing a collocated human-ankle/PGE mechanism, which has been numerically illustrated. The findings demonstrate that because the PGE joint do not restrict human ankle nature motion within the motion range of a typical ankle, it is less sensitive to joint misalignment as compared to conventional multijoint serial mechanisms that form a closed chain with the human limbs/joint. A prototype PGE has been designed; and its effectiveness for collocated ankle-joint manipulation has been experimentally investigated. Unlike conventional imaging methods that are prone to skin-marker errors and dependent on lumped-parameter approximations, the PGE directly measures the talus trajectory of the ankle-joint for characterizing its roll/slide motion and internal parameters.

Comfort optimization of a new type of foot mechanism for lower extremity exoskeleton

In order to reduce the impact caused by the contact between the foot and the ground when wearing the lower extremity exoskeleton under the condition of high load, this paper proposed an exoskeleton foot mechanism for improving the foot comfort, and optimized the key index of its influence on the comfort. Firstly, the physical model of foot mechanism was established based on the characteristics of foot stress in gait period, and then the mathematical model of vibration was abstracted. The correctness of the model was verified by the finite element analysis software ANSYS. Then, this paper analyzed the influence of vibration parameters on absolute transmissibility based on vibration mathematical model, and optimized vibration parameters with MATLAB genetic algorithm toolbox. Finally, this paper took white noise to simulate the road elevation as the vibration input, and used the visual simulation tool Simulink in MATLAB and the vibration equation to construct the acceleration simulation model, and then calculated the vibration weighted root mean square acceleration value of the foot. The results of this study show that this foot comfort mechanism can meet the comfort indexes of vibration absorption and plantar pressure, and this paper provides a relatively complete method for the design of exoskeleton foot mechanism, which has reference significance for the design of other exoskeleton foot and ankle joint rehabilitation mechanism.

State-of-the-Art Robotic Devices for Wrist Rehabilitation: Design and Control Aspects

Robot-assisted physical therapy of the upper limb is becoming popular among the rehabilitation community. The wrist is the second most complicated joint in the upper limb after shoulder in terms of degrees of freedom. Several robotic devices have been developed during the past three decades for wrist joint rehabilitation. Intensive physical therapy and repetitive self-practice, with objective measurement of performance, could be provided by using these wrist rehabilitation robots at a low cost. There has been an increasing trend in the development of wrist rehabilitation robots to provide safe and customized therapy according to the disability level of patients. The mechanical design and control paradigms are two active fields of research undergoing rapid developments in the field of robot-assisted wrist rehabilitation. The mechanical design of these robots could be divided into the categories of end-effector based robots and wearable robotic orthoses. The control for these wrist rehabilitation robots could also be divided into the conventional trajectory tracking control mode and the assist-as-needed control mode for providing customized robotic assistance. This article presents a review of the mechanical design and control aspects of wrist rehabilitation robots. Experimental evaluations of these robots with healthy and neurologically impaired are also discussed along with the future directions of research in the design and control domains of wrist rehabilitation robots.

Pelvic Support Hip Reconstruction with Internal Devices: An Alternative to Ilizarov Hip Reconstruction.

Aim and objectiveIlizarov hip reconstruction (IHR) is a traditional method of salvaging chronic adolescent problem hips but faces practical issues from external fixators leading to reduced compliance. We present the same reconstruction procedure using only internal devices with a modification in the technique and review early results.Materials and methodsWe retrospectively evaluated eight patients between 2014 and 2017 with chronic painful hips treated by two-stage reconstruction; stage I included femoral head resection and pelvic support osteotomy using double plating, whereas stage II comprised distal femoral osteotomy avoiding varus followed by the insertion of a retrograde magnetic nail for postoperative lengthening. Patients continued physiotherapy postoperatively while protecting from early weight-bearing.ResultsAt a mean follow-up of 19 months (range, 6–36), all osteotomies healed with a bone healing index of 47 days/cm (range, 30–72). Pain improved from 8.3 (range, 7–9) to 2 (range, 0–6) while the limb length discrepancy got corrected from 4.3 cm (range, 3–5) to 1.4 cm (range, 0–2.5) at the final follow-up. Trendelenburg sign was eliminated in three patients and delayed in five patients. No examples of infection or permanent knee stiffness were noted. One patient had plate breakage due to mechanical fall, and another patient had 35 mm of lateral mechanical axis deviation (MAD) requiring corrective osteotomy.ConclusionPelvic support hip reconstruction with exclusive internal devices is a technique in evolution with encouraging early results. It avoids common complications of external fixators and facilitates quick rehabilitation of joints. Refraining from distal varus can effectively eliminate Trendelenburg gait, although with some degree of lateral MAD. Unlike external fixation where there is a possibility of gradual correction, this staged procedure of internal fixation is technically demanding with a learning curve.Clinical significancePelvic support hip reconstruction performed by internal implants is a viable alternative to Ilizarov hip reconstruction with potential benefits.How to cite this articleMetikala S, Kurian BT, Madan SS, et al.
