all factors that are important for the individual in a certain physical, spiritual and mental respect; are mutually influenced by all other assessment parameters (damage, impairment of skills, social insufficiency). These factors include the material, social and personal environment in which a person arranges his life and which can have a beneficial effect (positive factors) on damage, impairment of skills or social deficiency and, thus, on the course of rehabilitation as a whole. Therefore, the influence of these factors should be recognized as early as possible and used for rehabilitation purposes (the concept of resources in rehabilitation). In addition, environmental factors can also have harmful effects (negative factors) on the body and thus exacerbate damage, skill impairment or social insufficiency.
