- Lesson Summary. Rigor mortis is the hardening of body muscles after death because of the body's loss of adenosine triphosphate (or ATP), which is a substance that gives energy to the muscles. Rigor mortis' general timeline moves from initial stiffening of the muscles to them regaining more flexibility again.

What Causes Rigor Mortis? A few hours after a person or animal dies, the joints of the body stiffen and become locked in place. This stiffening is called rigor mortis. Depending on temperature and other conditions, rigor mortis lasts approximately 72 hours.The phenomenon is caused by the skeletal muscles partially contracting.The muscles are unable to relax, so the joints become fixed in place.his stiffening is called rigor mortis. Depending on temperature and other conditions, rigor mortis lasts approximately 72 hours. The phenomenon is caused by the skeletal muscles partially contracting.

Abnormal posturing Abnormal posturing is an involuntary flexion or extension of the arms and legs, indicating severe brain injury. It occurs when one set of muscles becomes incapacitated while the opposing set is not, and an external stimulus such as pain causes the working set of muscles to contract.

Rigor Mortis and Other Postmortem Changes The muscles then stiffen, perhaps due to coagulation of muscle proteins or a shift in the muscle's energy containers (ATP-ADP), into a condition known as rigor mortis. All of the body's muscles are affected. Rigor mortis begins within two to six hours of death, starting with the eyelids, neck, and jaw. This sequence may be due to the difference in lactic acid levels among different muscles, which corresponds to the difference in glycogen levels and to the different types of muscle fibers.
