The purpose of the study is to define aspects of the patient's participation in the rehabilitation process and to define a conceptualization that improves the participation of the client. Materials and methods. The main research method is the method of analysis, which has been used to comprehensively review and evaluate the participation of the client in the rehabilitation process and an overall assessment of the structure that could improve the participation of the client. Results and discussion. One of the goals of the world community development is to preserve and strengthen human physical, social, mental and spiritual health. However, humanity has faced global environmental, economic, social and moral problems. The genetic burden of mankind, the ecological crisis, natural disasters and man-made disasters, wars and local conflicts and social instability lead to an increase in the need for rehabilitation. Therefore, in recent decades, the role of both the client and relatives in the rehabilitation process has changed, taking into account the participation of the client. In this paper, we consider the process of rehabilitation taking into account the participation of the client, as a variant of the client-oriented structure, the Canadian Occupational Performance Measure is evaluated primarily from the point of view of clients, occupational therapists and members of the rehabilitation team. The main goal is to maximize the participation of patients in the rehabilitation process. The emphasis of the occupational therapist is on the participation of the patient in determining outcomes and goals. Through years of practice and experience, occupational therapists have developed a model for client-centered practice in occupational therapy, namely the Canadian Model of Occupational Performance. And the result of using this model is the development of the Canadian Occupational Performance Measure, which has become a good tool for obtaining a result based on the client’s perception. Conclusion. Implementing a customer-centric approach is easier when a structured approach is used, but this is not enough. Participation and motivation of all team members are required, as well as support during the implementation period. Management support, knowledge of the underlying theory, time for discussion and reflection, as well as the opportunity to develop a personal interview technique, which indicates important factors for successful implementation, are also required
