R25-R29: Symptoms and signs involving the nervous and musculoskeletal systems

The group of conditions between codes R25 and R29 in the ICD-10 classification is dedicated to various signs and symptoms involving the nervous and musculoskeletal systems. These symptoms could include abnormal movements such as tremors, gait abnormalities, or balance disruptions caused by an underlying neurological or musculoskeletal condition. Some people might experience stiffness, rigidity, or spasms. The causes of these conditions are extensive and may involve diseases like Parkinson's, multiple sclerosis, or orthopedic injuries like a broken bone or sprain. Symptoms may worsen over time due to disease progression or inactivity, and they can restrict someone's mobility, ability to perform daily tasks, and overall quality of life. It's important to remember that these symptoms are usually signs of an underlying disease or condition that needs to be identified and treated by a healthcare professional.
