In accordance with the recommendations of the World Health Organization, the categories listed in the International Classification of Functioning (ICF) should be used to assess the structure, function, activity and participation. In recent years, the assessment of the state of the body is no longer possible without the use of scales, but a large number of them do not always allow specialists to understand each other. The creation of a unified system, which will collect various tools for assessing the patient’s condition, will provide serious assistance in the work of members of a multidisciplinary team in the process of medical rehabilitation. In addition, it will help in the formulation of rehabilitation diagnosis and in more accurate determination of rehabilitation potential. The dimension of a number of generally accepted scales to describe disorders of the musculoskeletal system does not coincide with the categories of ICF. This paper attempts to eliminate this contradiction. To describe a number of disorders that affect the function of the musculoskeletal system and are traditionally used in orthopedics, the category other or not described can be used. In the presented system of evaluation are given equal-weighted scale with the dimension adopted in the ICF. This system can be used as a basis for the preparation of medical rehabilitation programs and evaluation of their effectiveness.
