Learning outcomes

Biomechanics is concerned with the mechanical / anatomical bases of human movement. An interdisciplinary approach is used in which materials from anatomy, physiology and physics (mechanics) are integrated. Quantitative and qualitative biomechanical analyses of human movement are studied from the perspective of kinematic and kinetic descriptions of multi-segment motion. These external phenomena are used to estimate internal muscle mechanics and joint loading. The purpose of this course is to introduce students to concepts of mechanics as they apply to human movement. The student should gain an understanding of the mechanical and anatomical principles that govern human motion and develop the ability to link the structure of the human body with its function from a mechanical perspective, with particular attention to pathological conditions and changes across one lifespan. At the completion of this course it is desired that each student be able to: 1) describe motion with precise, well-defined mechanical and bio-mechanical terminology; 2) understand and quantify linear and angular characteristics of motion; 3) understand the quantitative relationships between angular and linear motion characteristics of a rotating body; 4) understand and quantify the cause and effect of force, linear and angular kinetic of human movement; 5) interpret and analyze the kinematic, kinetic parameters and muscle activation of normal and pathological gait; 6) evaluate the biomechanical properties of common movement task either in healthy and pathological conditions.

Examination Methods

Gait Inverse Dynamic Project (GP) 20%
Laboratory Project (LP) 30%
Final Exam (FE) 50%
Total 100%

Gait Inverse dynamic Project will be explained and assigned to the students after the lectures about “inverse dynamic”.

Laboratory Project will be assigned at the end of laboratory classes. Students will work on the project as a group (5-6 people) during the 10th to 16th laboratory class. The details of the projects will be given during laboratory classes.

Final exam will consist on a Written Test and an Oral Exam.
Written test:
• The written test will evaluate the capability to apply the logical and mathematical principles of the topics covered at the lectures.
• The written test will contain 30 multiple-choice questions.
• Each question will have a score from 1 to 3 for a total of 45 points. Incorrect and missing answers will have a score of 0.
• The written test grade will be obtained by dividing the test score by 1.5 (45/30)

Oral Exam:
• The admission to the Oral Exam requires ≥18/30 at the Written Test.
• The only admission to the Oral Exam does not guarantee to pass the Final Exam.
• It will consist in an oral discussion aimed to evaluate:
- Insightful understanding of course theoretical concepts;
- Use of proper terminology;
- Competency to translate the theoretical concepts to practical settings;
• The student is free to taking the Oral Exam either in Italian or English.
• Taking the Oral Exam in English will assign a Bonus of 1.5 points.

Final grade will be assigned as follows:
(GPx20 + LPx30 + FEx50)/(20+30+50)+English Bonus

N.B. Minimal requirement to pass the entire course: 18/30 in each part (i.e. GP,LP,FE)
