Manifestation
Cadaveric spasm may affect all muscles in the body, but typically only groups, such as the forearms, or hands. Cadaveric spasm is seen in cases of drowning victims when grass, weeds, roots or other materials are clutched, and provides proof of life at the time of entry into the water. Cadaveric spasm often crystallizes the last activity one did prior to death and is therefore significant in forensic investigations, e.g. holding onto a knife tightly.
