Introduction
With the progress of the contemporary rule of law,
forensic science plays an increasingly important role in
legal practice and has gradually become an important
means of ensuring judicial justice. Forensic scientists
frequently encounter trauma related cases in practice
and need to explain the causes of injury, such as the
type and strength of external forces and the biomecha-
nisms of injury [1]. However, traditional forensic sci-
ence relies mainly upon visual observation and empirical
judgment with subjective interpretation of the relation-
ship between external forces and injuries, which is
insufficient to meet modern scientific requirements for
evidence-quantitative objectivity and repeatability.
Recently, biomechanics has been gradually applied
in the field of forensic science. Interdisciplinary
research has contributed to the rapid development
of biomechanical techniques and the creation of a
series of related disciplines in medicine, sports sci-
ence, accident reconstruction, healthcare, and den-
tistry. Forensic biomechanics is evidence-based
science that applies biomechanical principles and
methods to forensic practice. Forensic biomechanics
focuses on exploring the causation of forensic phe-
nomena that are often deciding factors in injury,
civil, and criminal cases. Forensic biomechanics has
become an important branch of forensic science,
providing the means for more objective and quan-
titative forensic investigations, and it is one of the
research areas of forensic science that still have great
potential for development [1-3].
This review highlights current applications of
forensic biomechanics using material properties of
human tissue, injury criteria, injury scales, and injury
reconstruction, and describes research progress and
new applications of forensic biomechanics in China.
History and applications in medical-legal
situations
Since the 1970s, the rapid development of transpor-
tation has led to an increasing number of road traf-
fic accidents, which have fostered the integration of
forensic science and biomechanics. Meanwhile, com-
puter processing capabilities have rapidly increased
allowing the use of computer technology to solve
biomechanical forensic problems [4]. Marked by the
