It is characterized by the breakdown of the joint’s cartilage resulting in bones rubbing against each other, causing stiffness, pain and loss of movement in the joints.
OA differs from rheumatoid arthritis, which is a chronic, systemic inflammatory disorder that affects many tissues and organs, but principally attacks synovial joints.
A variety of other causes – hereditary, metabolic and mechanical – may initiate processes leading to loss of cartilage.
In many countries, OA is the second most common form of disability and has been declared an international health burden by the World Health Organization.
Approximately 80-90% of individuals older than 65 years have evidence of primary osteoarthritis.
Earlier trauma or wear-and-tear from repetitive use of joints such as repetitive stress syndrome of the hands promote OA. Interestingly, people with symptoms usually do not notice them until after they turn 50.
In individuals aged above 55, the prevalence of OA is higher among women than men.
Moderate levels of physical activity do not appear to increase the progression of OA, and may even offer some protection.
To help prevent the repetitive stress that can cause wear and tear on the joints of fingers that can lead to OA symptoms, using a comfortable, ergonomic pen whenever you write is a major step in the right direction. The UGLee Pen allows the hands and fingers to remain relaxed during use, which minimizes stress on the joints.
