Effect of the position of the interphalangeal joint on movements of the trapeziometacarpal joint during thumb opposition

The Kapandji test is a simple method to score thumb opposition; however, the position of the interphalangeal joint of the thumb during this test has not been described. We aimed to quantitatively examine the effect of the thumb interphalangeal joint position on movements of the trapeziometacarpal joint during thumb opposition using the Kapandji test. The Kapandji test was carried out in 20 healthy participants during thumb interphalangeal joint extension and flexion. Movements of the joints and the activity of thenar muscles were recorded using motion capture and electromyography, respectively. We found that interphalangeal joint extension increased the trapeziometacarpal joint movement and thenar muscle activity compared with interphalangeal joint flexion, which contributed to thumb opposition at Kapandji Positions 0–6. These findings suggest the position of the thumb interphalangeal joint affects the trapeziometacarpal joint during thumb opposition, and assessment of thumb opposition using the Kapandji test is best done with the thumb interphalangeal joint in extension.

Computer Intelligent Algorithm in the Recovery of the Elbow Joint Sports Injury Model

In this study, the inverse kinematics mathematics computer intelligent algorithm model is used to study the sports injuries of the elbow joint of adolescents. At the same time, we simulated the movement parameter changes during the rehabilitation training of the patient’s wrist and proposed a joint angular velocity function based on cubic fitting. Research has found that when the training scene changes greatly or the target task is changed, the smoothness of the elbow joint movement will change. The research conclusions of this article provide a theoretical basis for the selection of man-machine action points and the formulation of rehabilitation training methods. This article establishes the degree-of-freedom simulation model of the operating arm, which is the number of independent position variables in the operating arm, and these position variables determine the positions of all parts in the mechanism.

sEMG-Based Motion Recognition of Upper Limb Rehabilitation Using the Improved Yolo-v4 Algorithm

The surface electromyography (sEMG) signal is widely used as a control source of the upper limb exoskeleton rehabilitation robot. However, the traditional way of controlling the exoskeleton robot by the sEMG signal requires one to specially extract and calculate for complex sEMG features. Moreover, due to the huge amount of calculation and individualized difference, the real-time control of the exoskeleton robot cannot be realized. Therefore, this paper proposes a novel method using an improved detection algorithm to recognize limb joint motion and detect joint angle based on sEMG images, aiming to obtain a high-security and fast-processing action recognition strategy. In this paper, MobileNetV2 combined the Ghost module as the feature extraction network to obtain the pretraining model. Then, the target detection network Yolo-V4 was used to estimate the six movement categories of the upper limb joints and to predict the joint movement angles. The experimental results showed that the proposed motion recognition methods were available. Every 100 pictures can be accurately identified in approximately 78 pictures, and the processing speed of every single picture on the PC side was 17.97 ms. For the train data, the [email protected] could reach 82.3%, and [email protected]–0.95 could reach 0.42; for the verification data, the average recognition accuracy could reach 80.7%.

Pengaruh Foot Massage dan Pergerakan Sendi Ekstremitas Bawah terhadap Nilai Ankle Brachial Index (ABI) pada Pasien DM Tipe 2 di Wilayah Kerja Puskesmas Peukan Baro, Kab. Pidie

Diabetes mellitus Type 2 (DM Type 2) is the risk factor for the incidence of vascular. Diabetic neuropathy and/or peripheral arterial disease, are common and represent major causes of morbidity and mortality in people with diabetes. Physical exercises is have been done to prevent from diabetes complication, and one of them is by foot massage and lower extremity joint movement. Measuring the value of ankle brachial index (ABI) is one of non-invasive actions to evaluate the risk for peripheral vascular in primary treatment. The objective of this research was to determine the influence of foot massage and joint movement exercise on ABI value in DM Type 2 patients. The research used quasi experiment method with pretest-posttest group design and two intervention groups. The samples were 40 DM Type 2 patients, taken by using consecutive sampling technique. Intervention was given by conducting foot massage and lower extremity joint movement exercise. Wilcoxon Signed Ranks statistic test showed that there was the difference in pre and post intervention of foot massage and lower extremity joint movement from ABI value, for (p=0.00). The conclusion was that foot massage and lower extremity joint movement exercise could increase ABI value if it was done continuously. It could also increase blood flow to artery. This research could bean input for nursing care to make physical exercises such as foot massage and lower extremity joint movement as prevention from risk of longterm Complications in DM Type 2 patients.

Winect

WiFi human sensing has become increasingly attractive in enabling emerging human-computer interaction applications. The corresponding technique has gradually evolved from the classification of multiple activity types to more fine-grained tracking of 3D human poses. However, existing WiFi-based 3D human pose tracking is limited to a set of predefined activities. In this work, we present Winect, a 3D human pose tracking system for free-form activity using commodity WiFi devices. Our system tracks free-form activity by estimating a 3D skeleton pose that consists of a set of joints of the human body. In particular, we combine signal separation and joint movement modeling to achieve free-form activity tracking. Our system first identifies the moving limbs by leveraging the two-dimensional angle of arrival of the signals reflected off the human body and separates the entangled signals for each limb. Then, it tracks each limb and constructs a 3D skeleton of the body by modeling the inherent relationship between the movements of the limb and the corresponding joints. Our evaluation results show that Winect is environment-independent and achieves centimeter-level accuracy for free-form activity tracking under various challenging environments including the none-line-of-sight (NLoS) scenarios.

A Qualitative Expert Interview Study: Mobility Health in Indonesia

Background: Indonesia has an ageing population that can develop mobility health-related problems in the future, including osteoporosis, arthritis, sarcopenia, low back pain, neck pain, and peripheral neuropathy. However, there are limited references and research that look upon mobility health and problems surrounding it in Indonesia. Aims: To improve understanding on issues surrounding mobility health in Indonesia through a semi-structured interview with relevant experts. Method: Semi-structured qualitative interviews via phone calls were conducted with eight different experts. Data were analysed using reflexive thematic analysis. Experts with experience dealing with mobility (bone, muscle, joint, movement) related issues for more than ten years, working in Indonesia, and communicating in English or Bahasa Indonesia were included. Results: Four themes were then identified across the experts on issues surrounding mobility health in Indonesia; this includes [1] screening and assessment of mobility health, [2] treatment for mobility health problems, [3] awareness campaign, [4] supplement for mobility health. Conclusions: Diagnostic modalities for mobility health are abundant but still expensive. Treatment of mobility health with herbal medicine (jamu) might be beneficial. Social media can be a promising tool to increase awareness regarding mobility health. In general, there needs to be a change in mindset from curative to prevention in both health care providers and the general population.

Automatic interpolation algorithm for NURBS trajectory of shoe sole spraying based on 7-DOF robot

PurposeThe purpose of this paper is to propose an automatic interpolation algorithm for robot spraying trajectories based on cubic Non-Uniform Rational B-Splines (NURBS) curves, to solve the problem of sparse and incomplete trajectory points of the head and heel of the shoe sole when extracting robot motion trajectories using structured-light 3D cameras and to ensure the robot joints move smoothly, so as to achieve a good effect of automatic spraying of the shoe sole with a 7-degree-of-freedom (DOF) robot.Design/methodology/approachFirstly, the original shoe sole edge trajectory position points acquired by the 3D camera are fitted with NURBS curves. Then, the velocity constraint at the local maximum of the trajectory curvature is used as the reference for curve segmentation and S-shaped acceleration and deceleration planning. Immediately, real-time interpolation is performed in the time domain to obtain the position and orientation of each point of the robot motion trajectory. Finally, the inverse kinematics of the anthropomorphic motion of the 7-DOF robot arm is used to obtain the joint motion trajectory.FindingsThe simulation and experiment prove that the shoe sole spraying trajectory is complete, the spraying effect is good and the robot joint movement is smooth, which show that the algorithm is feasible.Originality/valueThis study is of good practical value for improving the quality of automated shoe sole spraying, and it has wide applicability for different shoe sole shapes.
