The multifidis muscle starts at the sacral bone at the base of the spine and extends upward to the second cervical vertebra. The multifidis takes pressure off the discs and it’s strength adds stability to the vertebral column. Though small it is the most powerful muscle that supports the region.
Studies show that the size of the multifidis and the risk for head and neck injuries are associated in contact sports. Once a neck injury occurs there is a rapid degeneration of the cervical multifidis and MRI’s show a fatty infiltration into the tissue. The muscle must be kept thick and strong along the entire spine and rehabilitated like any other region of the body post injury.
If you contract your shoulder muscles dynamically or isometrically there is an increase in thickness of the multifidis which serves to protect the head and neck. The muscle will thicken regardless of force direction to the shoulder or arm. This is a wonderful way our body safeguards us from excessive trauma – when an appendage is hit the cervical spine stiffens.
Take advantage of this small, but powerful muscle and make sure all athletes train and rehabilitate the multifidis……. Get Strong
