Funeral attempt
In cadaver experiments , the dynamic and kinematic behavior of the human body as a reaction to mechanical stress on cadavers (" post-mortem test subjects " or " post mortem human subjects (PMHS) ") is examined. They are mainly used in accident research.
The tests are used for calibration of crash test dummies , validating simulation results and to develop reliable restraint systems (are seat belts , airbags , pretensioners , etc.) and other protective equipment ( helmets , child seats , etc.) is required. Tests that require extreme mechanical loads can only be carried out on cadavers. The significance of such experiments on corpses is controversial, as the mechanical strength of a corpse does not fully correspond to that of a living person. The most important disruptive factors are the degree of rigor mortis and the decomposition processes that set in after death. In addition, injuries that are only expressed by a functional disorder such as loss of consciousness or paralysis are not accessible through cadaveric experiments.
advantages
- People living in a similar way anthropometrically
- Material properties of the tissue almost identical (depending on the time span since death and preparation)
disadvantage
- No muscle tension
- Mostly older people (results that are not representative)
- No physiological reactions
- Ethical concerns
