### Highlight from the Overview  
Based on the overview of the systematic reviews, a key added value is the recognition of multiple therapeutic applications of SASRs across different patient populations and healthcare settings. SASRs have been primarily designed to provide emotional and social support, cognitive assistance, and therapeutic interventions for specific needs, which can vary significantly depending on the condition or age group they are intended for. For instance, robots designed for emotional and social support often aim to alleviate loneliness, such as in elderly care or dementia, by offering companionship and emotional comfort. These robots can enhance patients' psychological well-being and contribute to reducing isolation, as seen in the studies by [PERSON] et al. [11], [PERSON] et al. [16], and [PERSON] et al. [21]. Likewise, robots used for cognitive support aim to assist individuals with dementia or autism, where they help stimulate cognitive functions like memory, problem-solving, or even task completion, as demonstrated in the work of [PERSON] et al. [14] and [PERSON] et al. [19]. Another added value stems from the flexibility and potential overlap between categories of SASRs. While robots primarily focused on emotional support often provide cognitive stimulation as well, this cross-functionality enhances their effectiveness. For instance, robots used in dementia care not only provide emotional comfort but can also engage patients in cognitive tasks, such as remembering names or following simple commands, thus helping to maintain cognitive function. This suggests that the design of SASRs should be flexible enough to address multiple therapeutic goals simultaneously, improving their utility in healthcare settings, as evidenced by the work of [PERSON] et al. [20] and [PERSON] et al. [22]. A third added value arises from the application of SASRs in diverse healthcare contexts. The reviews illustrate how SASRs have been successfully deployed in pediatric, geriatric, and dementia care settings. For example, in children's hospitals, robots have been used to alleviate stress and anxiety during medical procedures, promoting relaxation and distraction, as seen in the studies by [PERSON] et al. [20] and [PERSON] et al. [15]. Similarly, in geriatric care, robots have been used to support emotional health by alleviating depression, anxiety, and loneliness in older adults, enhancing their overall quality of life, as shown in the works by [PERSON] et al. [21] and [PERSON] et al. [19]. These applications highlight the adaptability of robots across different populations, underscoring the potential for robots to meet the unique needs of various patient groups. Furthermore, the reviews point to the need for more rigorous long-term research. Although the studies reviewed show promising short-term benefits of SASRs, there is a clear need for more longitudinal studies to assess the long-term efficacy and sustainability of these interventions. This would help determine the lasting impact of SASRs on emotional well-being, cognitive support, and overall health outcomes, as noted by [PERSON] et al. [22] and [PERSON] et al. [19]. Finally, the need for integration into healthcare systems is a significant consideration moving forward. As SASRs become more advanced, understanding how they can be seamlessly integrated into clinical workflows is crucial. This involves addressing practical issues such as how to incorporate robots into everyday care routines and ensuring that healthcare providers are adequately trained in their use. Additionally, ethical considerations around privacy, consent, and robot-human interaction will need to be carefully managed to ensure these technologies are used responsibly and effectively, as discussed by [PERSON] and [PERSON] [17] and [PERSON] et al. [12]. Overall, the systematic reviews reveal several added values from the use of SASRs in healthcare. These robots offer emotional, cognitive, and therapeutic support across diverse patient populations.
