**4. Conclusions**

Collectively, the studies presented in this Special Issue have used various validated biomechanical models or proposed novel methods of motion analysis to gain new insights into health-related problems and sports performance. As the editors of this Special Issue, we look forward to the continuous efforts of applying novel biomechanics-based motion analysis to support clinical practice and overcome any unsolved challenges. We expect that further steps are needed to translate the methodological developments of motion analysis methods into broader applications.
