“…The exoskeleton is an external mechanism that transmits the torques and forces generated by actuators near human joints through the joints they make with the outer part of the upper human limb [44] and Exosuits are soft exoskeleton that the anatomical structure of the human body forms its main framework [74]. The images of all three samples are shown in [20,73,75], and in this paper, as mentioned earlier, only two designs, Exoskeleton and Exosuit, have been examined for their wear ability.…”

“…They also use the structural integrity of the human body to transfer forces between different parts of the body [68]. Due to the lack of a rigid skeleton, the user's natural movements in Exosuit are not limited [73]. Exosuit exerts a force on the joints in parallel with the muscles, Which can improve the effect of the auxiliary force and the connection of the device system [21].…”

“…When dealing with system modelling, the dependence of the model parameters on the arm complexion of the wearer is important. In addition, the flexibility of the Exosuit makes it impossible to be placed on the arm always in the exact position [73]. Given the above, the expectations we should have from an Exosuit system can be as follows [57]:…”

The importance of the human upper limb role in performing daily life and personal activities is significant. Improper functioning of this organ due to neurological disorders or surgeries can greatly affect the daily activities performed by patients. This paper aims to comprehensively review soft and rigid wearable robotic devices provided for rehabilitation and assistance focusing on the shoulder joint. In the last two decades, many devices have been proposed in this regard, however, there have been a few groups whose devices have had effective therapeutic capability with acceptable clinical evidence. Also, there were not many portable, lightweight and user-friendly devices. Therefore, this comprehensive study could pave the way for achieving optimal future devices, given the growing need for these devices. According to the results, the most commonly used plan was Exoskeleton, the most commonly used actuators were electrical, and most devices were considered to be stationary and rigid. By doing these studies, the advantages and disadvantages of each method are also presented. The presented devices each have a new idea and attitude in a specific field to solve the problems of movement disorders and rehabilitation, which were in the form of prototypes, initial clinical studies and sometimes comprehensive clinical and commercial studies. These plans need more comprehensive clinical trials to become a complete and efficient plan. This article could be used by researchers to identify and evaluate the important features and strengths and weaknesses of the plans to lead to the presentation of more optimal plans in the future.

“…As the study presented in this document was implemented in an Exosuit developed in our group [ 31 ], these solutions were discarded for the first two DOF (abduction/adduction and flexion/extension). The third DOF of the shoulder ( Figure 2 e medial/lateral rotation) is revealed at the forearm and can be measured at the elbow.…”

Motion tracking techniques have been extensively studied in recent years. However, capturing movements of the upper limbs is a challenging task. This document presents the estimation of arm orientation and elbow and wrist position using wearable flexible sensors (WFSs). A study was developed to obtain the highest range of motion (ROM) of the shoulder with as few sensors as possible, and a method for estimating arm length and a calibration procedure was proposed. Performance was verified by comparing measurement of the shoulder joint angles obtained from commercial two-axis soft angular displacement sensors (sADS) from Bend Labs and from the ground truth system (GTS) OptiTrack. The global root-mean-square error (RMSE) for the shoulder angle is 2.93 degrees and 37.5 mm for the position estimation of the wrist in cyclical movements; this measure of RMSE was improved to 13.6 mm by implementing a gesture classifier.
