Deterioration, Impairment

Impairment is a term that denotes a deficiency or defect in the structure or functioning of the body. Such disorders may occur at the level of organs, tissues or body systems as a result of injury, disease, birth defects or gradual wear and tear.

Performance impairment results in a person's ability to perform certain activities or tasks being limited. It may affect physical, mental, sensory or emotional functions. For example, visual impairment due to cataracts, decreased mobility due to arthritis, speech impairment after a stroke.

The degree of impairment in activity may vary from mild to severe. In some cases, it leads to disability and the inability of a person to fully function without assistance. Early diagnosis and treatment of disorders often prevents the development of persistent and severe forms of impairment.

Deterioration in Performance

Introduction Deterioration in performance is a change in the initial level of activity and efficiency of an individual, organization or system, which is accompanied by a reduction in performance results. Examples: a person loses his sight due to blindness, the government loses control of the situation after bankruptcy. Deterioration may be due to the following factors: illness or injury; changing the situation; reluctance to act intensively; situation of violation of justice; presence of significant experience (entropy crisis); crisis of age-related changes (maintaining functionality), developmental crises (episode of understanding). Deterioration can occur in both the physical and mental spheres of a person. Implicit activity becomes inaccessible. The psychological mechanisms evoked are close to the mechanisms of cognitive adaptation (by the end of the working day, memory and concentration deteriorate). Initially, any activity involves numerous physiological systems. In this regard, within the framework of adaptation theory, the question of the limits of stability of the body's adaptive systems is considered. The ecological support model (V.V. Pashun) connects the complexity indicator of a system with the amount of adaptive information for it. It shows that adaptation depends on: whether a source (signal) is available to the system to ensure its activity; whether this source supports system functioning at a certain speed. Indicators of the organism's vulnerability (and, accordingly, a decrease in the size of the contribution to the general state) have limits that are easily tolerated when the correspondence of the signal to the physical implementation decreases. Some indicators decrease with a constant increase in stress on the body. It is not the rate of decline in the indicator that is growing, but its absolute value. Another quality one
