Hand gesture recognition based on surface electromyography (sEMG) plays an important role in the field of biomedical and rehabilitation engineering. Recently, there is a remarkable progress in gesture recognition using high-density surface electromyography (HD-sEMG) recorded by sensor arrays. On the other hand, robust gesture recognition using multichannel sEMG recorded by sparsely placed sensors remains a major challenge. In the context of multiview deep learning, this paper presents a hierarchical view pooling network (HVPN) framework, which improves multichannel sEMG-based gesture recognition by learning not only view-specific deep features but also view-shared deep features from hierarchically pooled multiview feature spaces. Extensive intrasubject and intersubject evaluations were conducted on the large-scale noninvasive adaptive prosthetics (NinaPro) database to comprehensively evaluate our proposed HVPN framework. Results showed that when using 200 ms sliding windows to segment data, the proposed HVPN framework could achieve the intrasubject gesture recognition accuracy of 88.4%, 85.8%, 68.2%, 72.9%, and 90.3% and the intersubject gesture recognition accuracy of 84.9%, 82.0%, 65.6%, 70.2%, and 88.9% on the first five subdatabases of NinaPro, respectively, which outperformed the state-of-the-art methods.

Introduction: Over the years, the popularisation of 3D printing technology created new possibilities for developing customized and cheap prosthetics in a shorter time than time-consuming and expensive conventional methods. With the available software and knowledge, there are limitless possibilities for tailoring every prosthetic exclusively to the patient when keeping the costs reasonably low. Objective: The objective of the study was to research, review and compare data available on PubMed about the use of 3D printing in the development of a prosthetic thumb. A brief description of the state of knowledge: Conventional methods of prosthetic manufacture require a skilled professional prosthetist, a lot of time, and the costs from 4000-8000$ for a body-powered one, to 25000-50000$ for an externally powered one. That could be a major financial barrier for a patient. The 3D printing technology development over the last 15 years provided a fast and cheap method of manufacture for low-batch prosthetics, including thumb prosthetics, while being able to easily alter the project to customize it to the patient’s needs. Conclusions: There is a possibility to create fully functioning and durable thumb prosthetics with 3D printing technology. However, we need more research to provide a universal and fully customizable one to meet every patient's needs.

“…Several studies have measured muscle activity while performing various grasping tasks. [17][18][19]24,25 Each study focused on different muscles in their experiments. One study measured fifteen extensor and flexor muscles associated with the fingers movement, 17 while another study measured ten muscles.…”

Millions of people suffer from a decline in grip strength and hand function due to conditions such as chronic disease, injuries, and aging. Hand function decline results in difficulties with performing activities of daily living, where grasping, lifting, and releasing objects are essential. There is an increasing demand for assistive gloves to enhance users’ hand function and improve their independence. This paper presents the design of a new bidirectional lightweight assistive glove and demonstrates its capabilities through comprehensive experiments using human subjects. The developed glove can provide adequate power augmentation for grasping and releasing objects due to its simple yet effective design using spring steel strips and linear actuators. The glove directly transfers assistive forces to users’ fingertips without any complex intermediate mechanism, and its low weight of 196 g promotes its usability. The rigorous experiment design provided a thorough assessment of the developed glove by accounting for both parameters of size and weight of objects and by including subjects with different hand sizes. To quantify the glove’s performance, the subjects’ muscle activity, their finger and thumb joints’ trajectories, and their grasping forces while using the glove were investigated. The glove could generate the necessary grasping forces to assist with lifting common-household objects. The subjects’ muscle activity significantly decreased when using the glove for object manipulation. The trajectories of the index finger and thumb joints when using the glove were dependent on the size of objects similar to natural unassisted grasping. The obtained results demonstrate the glove’s ability for grip power augmentation of individuals with declining hand strength.
