The most common cause of disability in the United States is often attributed to osteoarthritis. This condition affects a significant portion of the population and is primarily characterized by the degeneration of joint cartilage and the underlying bone, which leads to pain, stiffness, and decreased mobility. The prevalence of osteoarthritis increases with age, making it particularly common among older adults, who are a large demographic in the U.S.

While diabetes, cardiovascular disease, and cancer are serious health concerns and contribute to a substantial number of disabilities, they do not match the widespread impact of osteoarthritis in terms of both prevalence and the functional limitations it imposes on individuals. Osteoarthritis not only affects physical capabilities but can also lead to emotional and psychological challenges, further influencing the overall quality of life for those affected. Understanding this condition's significance in the context of disability helps inform rehabilitation approaches and interventions aimed at improving individuals' functioning and independence.
