Biomechanics

• Biomechanics
• Branch of Bioengineering and Biomedical
  Engineering
• Application of classical mechanics to the
  anallysis of biological and physiological systems
• Bioengineering and Biomedical Engineering
• Interdisciplinary field in which principles and
  methods from engineering, basic sciences, and
  technology are applied to design, test, and
  manufacture equipment for use in medicine and to
  understand, define, and solve problems in
  physiology and biology.

Biomechanics vs. Kinesiology

• Biomechanics
• Application of mechanics to biological systems
• More specific than kinesiology
• Yet also very broad in its study and application
• Kinesiology
• Scientific study of human movement
• Spans anatomical, physiological, psychological,
  biomechanical areas

8
Research in Biomechanics

• Experimental Studies
• Mechanical properties of biological materials
  (e.g. bone, cartilage, muscle, tendon, skin,
  blood)
• Anthropometry, Kinetics, Kinematics, EMG, Stress
  Strain
• Modeling
• Model Analyses
• Utilize measured initial conditions to simulate a
  hazardous effect (e.g. head impact)
• Phenomenological models model the response, to
  figure out initial conditions (e.g. determine
  heel pad stiffness based on impact attenuation)
• Theoretical models using experimental data
  (initial conditions) are used to predict the
  effect of environmental and operational factors
  without resorting to lab experiments (e.g. head
  impact)
• Applied Research
• Purpose is predominantly to benefit human function

My Research

• Impact Biomechanics (Injury Risk Factors)
• Knee load and ACL injury (landing, cutting)
• Head impact and injury
• Injury prevention (e.g. form training, strength
  training)
• Fall Prediction in the Elderly
• Functional dynamic balance in elderly
• Fall prediction during ADLs
• Intervention strategies (e.g. strength training,
  balance training)
• Modeling and Simulation
• Soccer Heading Simulation (head impact and
  injury)
• Joint Modeling (Knee model for ACL strain)
• Wobbling Mass Models (soft tissue motion)

12
ApplicationsInjury Prevention and Rehabilitation

• Biomechanics of the knee joint following ACL
  surgery
• Sport shoes and their role in motion control and
  shock absorption
• Landing mechanics indicative of a female
  predisposition to ACL injury
• Examination of the role of soft tissue motion on
  joint loading and injury
• Heading and head injury in youth soccer
