5. Mission, to be a catalyst for the scaling and use of biomechanics from the research environments to the applied science world of clinicians, specialists, and sports scientists. From my experience, these clinicians are searching for objective ways to assess and monitor their patients/athletes, which I believe biomechanics is the solution. Coleman Bessert

6. Mission: to contribute towards the advancement of evidence- based healthcare services in Africa through the development of world-class research facilities, professional expertise and student training curricula. John Cockcroft

7. Biomechanics: the study of the structure and function of biological systems using the principles of mechanics. TODAY’S FOCUS: Human musculoskeletal biomechanics: the study of the structure and function of the human musculoskeletal system during functional movement.

8. Electromyography (EMG): Recording of the electrical activity produced by skeletal muscles. TODAY’S FOCUS: Kinesiological EMG: the recording of electrical activity produced by skeletal muscles during movement. Surface EMG: the recording of electrical activity using electrodes mounted on the skin surface.
