What condition is characterized by morning stiffness and is relieved by physical activity?

The condition characterized by morning stiffness that improves with physical activity is often associated with osteoarthritis. This form of arthritis is commonly seen in older adults and is associated with wear and tear on the joints over time. Individuals with osteoarthritis typically experience stiffness upon waking, but this stiffness generally decreases with movement and activity throughout the day.

In contrast, rheumatoid arthritis tends to present with morning stiffness that lasts for a longer duration, often more than an hour, and may be accompanied by swelling, pain, and fatigue. While degenerative joint disease is a term often used to refer to osteoarthritis, it is important to note that osteoarthritis is the specific diagnosis that fits the criteria of experiencing morning stiffness that improves with movement.

Systemic lupus erythematosus is an autoimmune condition that can also cause joint pain and stiffness, but it does not specifically follow the same pattern of improvement with activity as seen in osteoarthritis.

Therefore, the emphasis on morning stiffness that is relieved by physical activity clearly aligns with the characteristics of osteoarthritis, making it the most appropriate choice in this context.
