Knowledge Model for Interactive Safety Performance Indicators for Wearable Rehabilitation Robot: Uniform Standards for Interaction Safety Testing

Abstract

Wearable rehabilitation robot (WRR) has become an important tool in the clinical application of rehabilitation medicine, and as WRR is usually attached to the patient's body and in close contact with the therapist, the safety of interaction during rehabilitation is an important consideration for device developers. As the WRR is still in its early stages of development, there is still a gap in international safety standards or technical standards for WRR. As more and more research is conducted on WRR and the technology is gradually improved, the corresponding safety test methods and indicators should be gradually improved. In order to gain a comprehensive understanding of the research hotspots and frontier areas in the field of WRR interactive safety performance, this study analyses the annual distribution of literature, distribution of journals, distribution of research power, important literature, research hotspots and frontiers based on bibliometric methods, and constructs a knowledge model of WRR interactive safety performance indicators. It is found that the research hotspots in WRR safety performance research are mainly focused on four areas: clinical reliability testing, safety performance testing equipment development, mechanical structure optimization and control algorithm optimization. Based on the above research, the knowledge model of interactive safety performance indicators is drawn, and the unified standard for interactive safety testing in the field of WRR safety performance is analyzed and summarized to provide reference for the construction of testing methods for the unified standard for WRR safety testing.
