What kind of joint movement is associated with no Range of Motion (ROM)?

The type of joint movement associated with no Range of Motion (ROM) is classified as synarthrosis. This type of joint is characterized by its immobility, meaning that the bones are tightly bound and do not allow for movement. An example of synarthrosis can be found in the sutures of the skull, where the bony edges are interlocked and held together by fibrous connective tissue, providing stability and protection for the brain.

In contrast, other types of joints allow for varying degrees of movement. Amphiarthrosis joints permit a small amount of movement, while diarthrosis joints are highly mobile, allowing for significant movement in various directions. Osteoarthritis, on the other hand, is a degenerative joint condition that affects the cartilage and can lead to reduced movement due to pain and stiffness, but it does not define a type of joint movement. Thus, synarthrosis is the specific classification that signifies a complete absence of movement, making it the correct answer.
