Learning objectives

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 and quantify the cause and effect of force, linear and angular kinetic of human movement; 4) comprehend the biomechanical principles of the musculoskeletal system in human movements with particular attention to elderly population and subjects with neuromuscular deficits; 5) interpret and analyze the kinematic, kinetic parameters and muscle activation of normal and pathological gait; 6) evaluate the biomechanical properties of common movement tasks either in healthy and pathological conditions.

Program

Lectures: • Anthropometry: density, segment mass, center of mass, moment of inertia, radius of gyration, use of anthropometrics tables. • Linear and Angular Kinematics: linear velocity & acceleration, differentiation of kinematic data; joint angles, joint angular velocity, joint angular acceleration. • Linear and angular Kinetics: Newton’s Laws, Link segment model, type of forces, joint force, joint torque. • Statics/Equilibrium: conditions for equilibrium, levers and pulleys, applications of statics to biomechanics, joint and muscle forces in static condition. • Posture: biomechanics of standing, joint mechanics during standing, equilibrium conditions during standing; biomechanics of toppling; biomechanics of anticipatory and compensatory postural adjustments, abnormal posture: pathologies and postural deficits. • Inverse Dynamics • Impulse and Momentum: linear and angular impulse, linear and angular momentum, applications to human movement. • Work - Energy - Power: definition of work, energy and power, work, energy and power in linear motion, work, energy and power in angular motion. • Gait: spatial-temporal parameters of gait, kinematic of gait, kinetic of gait, muscles intervention during gait cycle, pathological gait. • Reaching/Pointing: Biomechanics of reaching and pointing movements, reaching and pointing in pathological conditions. • Common movement tasks in clinical assessment: gait initiation, stair ascending and descending, landing, seat & stand.

Learning assessment procedures

Final grade will consist of the weighted arithmetic mean of the 3 following evaluations:
- Final Exam (FE) 85%
- Laboratory project (LP) 10%
- Gait inverse dynamic project (GP) 5%

Final exam (FE)
The final exam will consist of 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 consist of 30 questions: multiple-choice and short answer questions.

Oral 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 take the oral exam either in Italian or English.
Taking the oral exam in English will assign a bonus of 2 points.

Laboratory Project (LP)
Students will work on the project as a group of 5-6 people based on data collected in the biomechanics lab. The details of the project will be given during the practical lectures.

Gait Inverse Dynamic Project (GP)
Gait Inverse dynamic Project will be explained and assigned to the students after the lecture about the inverse dynamic and during the practical lectures.

Evaluation criteria

Final exam (FE)
Written test:
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 a score ≥18/30 at the written test.
The only admission to the oral exam does not guarantee to pass the final exam.

Laboratory Project (LP)
The laboratory project will receive a score based on the 30-point scale.

Gait Inverse Dynamic Project (GP)
The project will be evaluated during the oral exam, and it will be scored with a scale from 0 to 5 points and eventually converted in the 30-point scale; 0=fail, 1=18/30, 2=21/30, 3=24/30, 4=27/30, 5=30/30.

Criteria for the composition of the final grade

The final grade will be assigned as follows:
(FEx85 +LPx10+GPx5)/(85+10+5)+English bonus of the oral exam

N.B. Minimal requirement to pass the entire course: 18/30 in each of the 3 evaluations (i.e. FE, LP, GP)

Academic Honesty Policy:
Given the professional nature of our program academic dishonesty is not tolerated in this course. Any substantiated instances of academic dishonest will result in a zero for the assignments (projects and/or final exam) and consequently a final course grade of 0/30.
