“…Significant advancements have been reported for upper limb rehabilitation using exoskeletons, with some being integrated into clinical practice and commercialised [42], [43]. However, these rehabilitation systems often require continuous monitoring and assistance from therapists and are typically bulky, heavy, and impractical for daily tasks at home [44], [45]. To the best of the authors' knowledge, only two review articles have explicitly addressed exoskeletons for elderly activities of daily living assistance, focusing on upper limb [24] and lower limb exoskeletons [25].…”

Population ageing is a major global issue. The elderly population aged 65 and above made up approximately 9% of the world's population in 2019, with projections indicating this will rise to 16%, or 1.5 billion individuals, by 2050. The elderly experience a natural decline in strength, endurance, agility, and flexibility. Exoskeletons have the potential to assist the elderly in daily tasks, improve mobility and balance, and provide additional strength, endurance, and capability to maintain accurate limb movement. Their application leads to a more independent and autonomous life, fostering healthy ageing and ageing in place. However, their development requires thorough considerations of functionality and user experience criteria, such as addressing the alignment with human joints, social acceptance, and motivation for exoskeleton usage. This review presents an overview of upper-limb exoskeletons designed to assist the elderly in activities of daily living, focusing on exoskeleton types and assessments. Eighteen upper limb exoskeletons were identified from the literature and categorised based on supported body segment and structure. Most of the exoskeletons are either in the embodiment design or prototyping stages and their evaluations were predominantly performed in the laboratory or simulated environment. Elderly participation in exoskeleton assessment is currently limited. There is a lack of standardized exoskeleton assessments essential for certifications, commercialization, and universal benchmarks in diverse studies. These standards would ensure consistent, repeatable, reliable, validated, and comparable findings

“…State-of-the-art wearable robots can effectively reduce workload; however, limitations related to user comfort and acceptance are a major remaining barrier to widespread use (Kermavnar et al, 2021), together with high cost. It was recognized in early exoskeleton research that a certain amount of discomfort was experienced by the users (Abdoli-E and Stevenson, 2008;Wehner et al, 2009), while newer models have been reported to minimize this discomfort to a tolerable level (Sirawattanakul and Sanngoen, 2020;Kermavnar et al, 2021). Some wearable robots are heavy and bulky (Stadler et al, 2016;García et al, 2020), which can interfere with the user's freedom of movement.…”

The science and technology of wearable robots are steadily advancing, and the use of such robots in our everyday life appears to be within reach. Nevertheless, widespread adoption of wearable robots should not be taken for granted, especially since many recent attempts to bring them to real-life applications resulted in mixed outcomes. The aim of this article is to address the current challenges that are limiting the application and wider adoption of wearable robots that are typically worn over the human body. We categorized the challenges into mechanical layout, actuation, sensing, body interface, control, human–robot interfacing and coadaptation, and benchmarking. For each category, we discuss specific challenges and the rationale for why solving them is important, followed by an overview of relevant recent works. We conclude with an opinion that summarizes possible solutions that could contribute to the wider adoption of wearable robots.

The series elastic actuators make more comfort in the use of assistive exoskeletons. In this paper, an assistive controller is designed for a series-elastic-actuator-driven knee exoskeleton to restore normative mobility of individuals with weak muscles. The main target of the proposed controller is to modify the dynamics performance of the coupled humanexoskeleton system. In other words, the proposed controller modifies the relationship between the net muscle torque exerted by the human and the resulting angular motion. There are fewer sensors in the proposed intent-independent method relative to other methods. Moreover, there are less controller coefficients to regulate where these coefficients are extracted from a type zero Takagi-Sugeno-Kang fuzzy system. The performance of the controller is evaluated by simulations and experiments. The amplitude of the EMG signals decreased in a healthy person worn the SUT-KneeExo. Moreover, the proposed algorithm has a better performance in comparison with integral admittance shaping mothed and output feedback assistive controller. In other words, the amplitude of the integral admittance is more and the phase lag is less than other methods.
