The article notes that the law guarantees everyone the right to health care and medical assistance. A full-scale invasion calls for the development and updating of legal acts on ensuring a person’s right to medical assistance, in particular, to the provision of rehabilitation services. It is noted that rehabilitation assistance is aimed at a number of main areas, firstly, at supporting the functions of the patient’s body during the exacerbation of chronic diseases. Secondly, for warning, early diagnosis of disorders of the organs and systems of the patient’s body. The third direction is aimed at full or partial restoration of damaged organs or systems and compensation of lost functions of affected organs or systems. The fourth direction is related to the prevention and reduction of the degree of disability. The author emphasizes that the lack of competent and effective medical rehabilitation in Ukraine is a multifactorial problem: there is an insufficient number of inpatient and outpatient rehabilitation departments; lack of medical personnel - rehabilitation specialists, psychologists; there is not enough rehabilitation equipment; there is a need for adequate educational programs for physicians. In the article, the author emphasizes that one of the tasks of the state is to help persons with disabilities realize their constitutional rights; implementation of state policy in the field of rehabilitation of persons with disabilities, support for their integration into society, and the full-scale war on the territory of Ukraine causes an increasing urgency and need for the rehabilitation of persons injured as a result of hostilities. Such factors of the population’s health, such as the increase in morbidity, injuries, temporary loss of working capacity, premature mortality of the population require the development of the rehabilitation medicine market of Ukraine and its legal regulation. The article notes that the positive aspects are the development of new medical rehabilitation technologies, including those based on telemedicine and IT technologies, the preparation of new professional standards for medical rehabilitation at the modern level in accordance with international recommendations. All this requires the effective functioning of the system, which first of all requires the improvement and development of regulatory and legal support in the field of rehabilitation.
