This combination allows each actuator to have a unique variable stiffness profile based on the pattern and the temperature used to activate the PLA. Combinations of these patterns are used to create 12 designs, where each design consists of two different patterns in its top and bottom parts. The proposed actuators are 4D printed using four patterns, including grid, honeycomb, triangular, and rectilinear patterns. Therefore, this paper presents the use of 4D printed variable stiffness polylactic acid (PLA) actuators to create a variable stiffness gripper. This technique relies on the use of smart materials that change their shapes based on external stimuli. Four-dimensional (4D) printing allows creating complex structures that change their shape over time. So far, the use of soft materials in these variable stiffness grippers is limited. Such robots perform several tasks that require gripping objects while varying their stiffness values to adapt to the characteristics of the objects. The use of robots in various industrial applications keeps increasing every day. Results showed that the proposed tele-rehabilitation system enabled therapist-in-the-loop to dynamically adjust the rehabilitation intensity and provided more interactivity in therapist-patient remote interaction.

Preliminary experiments were conducted to demonstrate the feasibility of the proposed alternative training methods and evaluate the functionality of the developed tele-rehabilitation system. In this paper, we develop a home-based tele-rehabilitation system that implements two alternative training methods, including a haptic-enabled guided training that allows the therapist to adjust the intensity of therapeutic movements provided by the rehabilitation device and a surface electromyography (sEMG)-based supervised training that explores remote assessment of the patient's kinesthetic awareness. However, existing telerobotic systems for rehabilitation face barriers to implementing appropriate therapy treatment due to the lack of effective therapist-patient interactive capabilities.

However, some limitations related to the design and functionalities in the application domain were identified.Īs a promising alternative to hospital-based manual therapy, robot-assisted tele-rehabilitation therapy has shown significant benefits in reducing the therapist's workload and accelerating the patient's recovery process. The developed proposal shows potential as an economical product that health professionals can use. Through the execution of a case study in a real environment, the device was validated, where the results suggest a functional and workable prototype that supports the treatment of pathologies in the elbow area through the execution of the mentioned movements, supposing that this is a low-cost alternative with elements to improve, such as the industrial design and new functionalities.

For the development of the rehabilitation prototype, mechatronic design, co-design, and IDEF0 methodologies are used, performing activities such as actuator characterization, simulations, and modeling, among others. Therefore, this research proposes the mechatronic design of an orthosis with a graphic interface that supports professionals in the rehabilitation of the elbow joint through the execution of flexion–extension and pronation–supination movements. Injuries in the elbow area, such as lateral and medial epicondylitis, are the leading causes of consultation with health specialists. By regulating the joint stiffness, the proposed device could provide variable power assistance for the wearer's elbow movements.

An elbow power-assist trial with different actuated joint stiffnesses was tested on a healthy subject to evaluate the functionality of the proposed device. It has five passive degrees of freedom to guarantee the user's natural joint range of motion and intra-subject variability, as well as an integrated variable stiffness actuator (VSA) which can adjust the joint stiffness independently by moving the pivot position.

In this paper, we present a novel portable exoskeleton device which could provide support for rehabilitation patients with variable actuated stiffness in the elbow joint. Additionally, the actuated stiffness of the target joint is desired to be adjustable in accordance with the specific impairment level of the patient's upper limb. However, in order to be used in home-based rehabilitation, the kinematic structure of a wearable exoskeleton device should provide portability and make allowances for the natural joint range of motion for the user. Robot-assisted movement training by means of exoskeleton devices has been proven to be an effective method for post-stroke patients to recover their motor function.
