Nowadays, upper-limb injury or impairment represent a widespread problem, related to sport accidents or traumas, surgery operations, stroke and so on. The typical approach to the rehabilitation is one or more physiotherapy sessions, to restore muscular mass and strength. Despite this, over the years, several works proposed innovative solutions, including electromechanical orthoses, which work in relation to the muscular activity, measured by techniques such as superficial electromyography (sEMG). Yet, these systems are still far from commercialization because of their cost, complexity and difficulties in using. A currently unmet need regards the ability of the therapist to control and manage data through a remote interface, by exploiting some of the latest technological resources on the market (smartphones, tablets). The present works aims at designing an upper-limb rehabilitation system, based on an orthosis, sEMG wireless sensors and a dedicated software architecture to overcome these limitations. This will lead to an important change of perspective in physiotherapy procedures since data collection and correlation will produce innovative medical protocols, addressed to people affected by several types of injury or impairment.

In order to make most patients recover most of their limb functions after rehabilitation training, virtual reality technology is an emerging human-computer interaction technology, which uses the computer and the corresponding application software to build the virtual reality environment. Completing the training tasks in the virtual environment attracts the patients to conduct repeated training in the game and task-based training mode and gradually realizes the rehabilitation training goals. For the rehabilitation population with certain exercise ability, the kinematics of human upper limbs is mainly analyzed, and the virtual reality system based on HTC VIVE is developed. The feasibility and work efficiency of the upper limb rehabilitation training system were verified by experiments. Adult volunteers who are healthy and need rehabilitation training to participate in the experiment were recruited, and experimental data were recorded. The virtual reality upper limb rehabilitation system was a questionnaire. By extracting the motion data, the system application effect is analyzed and evaluated by the simulation diagram. Follow-up results of rehabilitation training showed that the average score of healthy subjects was more than 4 points and 3.8 points per question. Therefore, it is feasible to perform upper limb rehabilitation training using the HTC VIVE virtual reality rehabilitation system.

In order to improve the convenience and practicability of home rehabilitation training for post-stroke patients, this paper presents a cloud-based upper limb rehabilitation system based on motion tracking. A 3-dimensional reachable workspace virtual game (3D-RWVG) was developed to achieve meaningful home rehabilitation training. Five movements were selected as the criteria for rehabilitation assessment. Analysis was undertaken of the upper limb performance parameters: relative surface area (RSA), mean velocity (MV), logarithm of dimensionless jerk (LJ) and logarithm of curvature (LC). A two-headed convolutional neural network (TCNN) model was established for the assessment. The experiment was carried out in the hospital. The results show that the RSA, MV, LC and LJ could reflect the upper limb motor function intuitively from the graphs. The accuracy of the TCNN models is 92.6%, 80%, 89.5%, 85.1% and 87.5%, respectively. A therapist could check patient training and assessment information through the cloud database and make a diagnosis. The system can realize home rehabilitation training and assessment without the supervision of a therapist, and has the potential to become an effective home rehabilitation system.
