“…These restrictions may result from the hardware system and control mechanism. The problems related to the hardware implementation represented in limitation in reflected range of motion, bulky and complexity, costly, uncomfortable, heavy in weight, incompatibility of the mechanical structure with that of the human, deficiency in safety purposes and power transmission methods [9][10][11][12][13][14][15][16]. In an appropriate form, the rehabilitation devices must be accessible for all patients through their existent in hospitals and rehabilitation centers.…”

“…As a result, many researchers have been interested in this field in which they developed and introduce new rehabilitation devices aiming to override the problems as much as possible [16][17][18]. However, the proposed devices still need several enhancements and reinforcements in terms of the technology usage in the implementation and manufacturing of them, the number of degree of freedom that shows by the considered device required to rehabilitate the defected limb to its optimum level, their restricted mode of operations which reflect on the efficiency of the rehabilitation process, their limitations to concerned on specific defected cases.…”

Regaining the activities of daily living after stroke and spinal cord injury requires repetitive and intensive tasks, meaning that rehabilitation therapy should be treated with a long duration. Thus, the need for rehabilitation devices based home is of most importance to increase the rehabilitation process and provide more comfortability for patients. This paper focuses on implementing and construction of a three degree of freedom (DOF) (flexion/extension, adduction/abduction, and pronation/supination), low cost, lightweight, and portable robotic exoskeleton for wrist-forearm rehabilitation. SolidWorks software program and 3D printer technology are used to model and construct the proposed robotic exoskeleton structure. In addition, the anthropometric parameters of the normal human lower arm are considered for this exoskeleton to provide a range of motion (ROM) and velocity for the links, joints, which matches with the anatomical structure of human and also to avoid the excesses motions over the normal range. The exoskeleton is constructed by a 3D printer utilizing polylactic acid (PLA) plastic material. The proposed implementing structure of the robotic exoskeleton shows comfortable, lightweight, simple and economic as well.

“…McKibben muscles can have low bandwidth for certain human movements (Wehner et al 2012) and can cause discomfort related to friction from the constantly varying surface area when in contact with the body (Davis et al 2003). Some PAM actuators address these issues by decreasing the overall size for more effective operation (Hiramitsu et al 2019) and increasing the types of motions that the actuators can achieve (Sasaki et al 2005a;Hassanin et al 2017;Funabora 2018). These new approaches are opening doors to biologically inspired exosuits that have the high force-to-weight ratio of a McKibben muscle (Bilodeau et al 2018) but with less weight, bulk, lower operating pressures, and a higher degree of transparency and flexibility for the user (Abe et al 2018;Hiramitsu et al 2019).…”

This review meta-analysis combines and compares the findings of previously published works in the field of soft wearable robots (SWRs) that provide active methods of actuation for assistive and augmentative purposes. A thorough investigation of major contributions in the field of an SWR is made to analyze trends in the field focused on fluidic and cable-driven systems, prevalent and successful approaches, and identify the future direction of SWRs and active actuation strategies. Types of soft actuators used in wearables are outlined, as well as general practices for fabrication methods of soft actuators and considerations for human–robot interface designs of garment-like exosuits. An overview of well-known and emerging upper body (UB)- and lower body (LB)-assistive technologies is categorized by the specific joints and degree of freedom (DoF) assisted and which actuator methodology is provided. Different use cases for SWRs are addressed, as well as implementation strategies and design applications.

“…Actuators made of fabrics work at lower pressures than elastomer actuators due to their inherent stiffness [ 75 ]. Therefore, several researchers have work on design, characterization, manufacture, and evaluation of soft elastomer actuators for hand [ 76 – 78 ] and wrist [ 79 ] rehabilitation.…”

This paper establishes design criteria for soft exogloves (SEG) to be used as rehabilitation or assistance devices. This research consists in identifying, selecting, and grouping SEG features based on the analysis of 91 systems that have been proposed during the last decade. Thus, function, mobility, and usability criteria are defined and explicitly discussed to highlight SEG design guidelines. Additionally, this study provides a detailed description of each system that was analysed including application, functional task, palm design, actuation type, assistance mode, degrees of freedom (DOF), target fingers, motions, material, weight, force, pressure (only for fluids), control strategy, and assessment. Such characteristics have been reported according to specific design methodologies and operating principles. Technological trends are contemplated in this contribution with emphasis on SEG design opportunity areas. In this review, suggestions, limitations, and implications are also discussed in order to enhance future SEG developments aimed at stroke survivors or people with hand disabilities.
