Rigor mortis, the stiffening of muscles after death due to fluctuation
in ATP levels.  Rigor mortis can make it
challenging to position a body for preparation. But don’t worry—our mnemonic,
F.E.R.M., makes the process straightforward and easy to remember. Let’s break
it down:

F is for Flex.

Start by gently flexing the joints. For example, bend the arms at the elbows or
the legs at the knees. The goal here is to loosen up the major joints without
applying excessive force.

E is for Extend.

Once the joint has some flexibility, extend it slowly. Straighten out the limbs
to encourage the muscle fibers to relax further.

R is for Rotate.

Now, rotate the joints gently. This helps stretch out the muscles and break
down the stiffness even more. Think of this as a circular motion—nothing sharp
or sudden.

M is for Manipulate.

Finally, manipulate the muscles by massaging or pressing along the limbs. This
final step can release any remaining tension, ensuring the body is ready for
proper positioning.

Remember, the key is to take your time and use a respectful, measured approach.
Flex, Extend, Rotate, and Manipulate—F.E.R.M.—it’s simple, effective, and
dignified.
