[Estimation of the height of free fall of a human body on the basis of experimental expression of the degree of injury].

The author evaluated 204 deaths caused by blunt force as a result of incidence after a free fall from an altitude of 2 do 45 metres. Experimentally a score of severity od different types of traumatic changes was created. In every case the quantity of injury was expressed. Its dependence on the incident kinetic energy of the body, the mobility of incidence and rate of incidence was investigated. The closest correlation with the quantity of injury, based on mathematical and statistical evaluation, was found for the incident mobility of the body (Ns), the least one for the rate of incidence (m/s). In free falls with an incidence on a flat surface (asphalt, concrete, pavement, trampled soil the author suggests a procedure of estimation of the probability interval (p = 95%) of the altitude of the fall. The procedure could be used in forensic practice in cases with an unknown altitude of the fall and to test the trustworthiness of data concerning the altitude of the fall.
