What is inflammation of bursae, fluid-filled sacs that decrease friction, known as?

The condition characterized by inflammation of the bursae, which are small, fluid-filled sacs located throughout the body that help reduce friction between tissues such as bone and tendons or muscles, is known as bursitis. This inflammation can occur due to repetitive motion, trauma, or prolonged pressure on the bursae, leading to pain and swelling in the affected area. Bursitis commonly affects areas such as the shoulder, elbow, hip, and knee. Understanding this condition is essential in physical therapy, as it can significantly impact a patient's mobility and overall function.

The other terms listed refer to different medical conditions: bradykinesia is a symptom of Parkinson's disease characterized by slow movement, chronic inflammation refers to prolonged inflammation that can occur in various conditions but is not specific to bursae, and cerebral palsy is a group of neurological disorders that affect movement and muscle tone, unrelated to the inflammation of bursae.
