In our last blog post, we talked about the potential complications of immobility for those with spinal cord injuries (SCIs). In this blog post, we’ll elaborate on issues such as decreased bone mineral density (BMD) and the potential for joint contractures (joint immobility).
Bone Mineral Density
In a healthy individual, the body goes through a cycle of reabsorbing minerals from the bones to use (or in a sense, borrow) for other bodily functions and processes to keep the body in homeostasis (regulating properly). The body then replaces the minerals, adding them back to the bone. At about the age of 30, bone density starts to slowly decrease, as the body reabsorbs the minerals faster than it can be replaced in the bone. There are other factors that may speed bone density loss, such as:
