Changes with Age. In most cases, a person's normal respiratory rate will change with age; younger adults, children, and babies will typically have faster respiratory rates, because as people age, their breathing usually slows down.
Modic changes are pathological changes in the bones of the spine, the vertebrae. These changes are situated in both the body of the vertebrae and in the end plate of the neighboring disc.
Modic changes and pain [edit]. Many studies have examined the relationship between Modic changes in the vertebrae in the spine and pain in the lower back. There is a very strong correlation between having Modic changes, especially Modic changes type 1, and suffering from pain in the lower back.
