Rheumatic diseases are a collective term for a number of different conditions that mainly affect the musculoskeletal system. They can limit mobility and significantly reduce quality of life. Rheumatic diseases can affect both younger and older people. The exact cause of inflammatory rheumatic diseases is not fully understood, but possible developmental factors include hereditary factors and environmental influences. Depending on the cause of the disease, they are most commonly classified as one of two types: inflammatory or degenerative. Rheumatic pain is the most common symptom of these diseases and is what brings patients to the doctor. It is accompanied by very poor joint function with limited movement. When it comes to inflammatory diseases, pain occurs at rest and is relieved by movement and physical activity. In the case of degenerative diseases, the pain is caused by or immediately after the strain on the body and disappears when resting. The diagnosis is made on the basis of the patient's medical history, clinical examination, certain laboratory tests and X-rays. Inflammatory rheumatic diseases can manifest as rheumatoid arthritis or psoriatic arthritis. Degenerative rheumatic diseases most often occur due to excessive load on the individual joints and due to various injuries or improper posture, but heredity also plays a certain role. This group of diseases includes osteoarthritis. The aim of treatment for rheumatic diseases is to relieve pain, maintain joint mobility and increase range of motion. Occupational therapy aims to prevent, improve and maintain as many activities of daily living as possible. A very important factor in ADLs are medical aids that protect the patient's joints, reduce the extreme pain associated with rheumatic diseases. The cooperation between the occupational therapist, the patient and the family is very important for the patient's re-adaptation to the environment and for learning how to use the medical aids.
