B2569 - LABORATORIO DI BIOMECCANICA DEL MOVIMENTO

Learning outcomes

By the end of the course, the student will have acquired knowledge of the functioning and proper use of instrumentation for the biomechanical analysis of human movement, the design of experiments in the field of biomechanics, and the critical interpretation of experimental results. In particular, the student will be able to: - use quantitative motion analysis instrumentation typically found in motion analysis laboratories (such as that available in the Biomedical Engineering Lab); - design experiments based on the knowledge acquired; - conduct experiments with the assistance of the instructor; - process data to identify and estimate relevant biomechanical variables; - analyze the kinematics and dynamics of human movement using stereophotogrammetry and force platforms; - study muscle electrical activity through surface electromyography (sEMG); - use inertial measurement units (IMUs) for the analysis of movement kinematics.

Course contents

Part 1 - Measurement of kinematics
Methods and tools for the measurement of kinematic quantities: position, velocity, acceleration. 2D video analysis. The stereophotogrammetry: basic principles, errors, calibration, spot-checks. Estimation of position and orientation of a rigid body in 3D space. Estimation of joint orientation.

Part 2 - Measurement of dynamical variables
Methods and tools for the measurement of external forces: the force platform. Experimental determination of center of pressure and ground reaction forces. Methods and tools for the experimental determination of anthropometric parameters. Estimation of net internal joint moment.

Part 3 - Electromyography and Inertial Measurement Systems
Methods of measurement of muscle activity. Experimental determination of kinematics using accelerometer and gyroscope, comparison with measurements from stereophotogrammetry.

Part 4 - Applications
Kinematic and dynamic analysis of motor tasks: gait, sit-to-stand, reaching, vertical jump.

Readings/Bibliography

Lecture notes provided by the teacher.

Teaching methods

The course comprehends ex-cathedra lessons for the presentation of theoretical concepts and practical exercises at the Laboratory of Biomedical Engineering. In particular, the practical exercises with laboratory instrumentation are carried out in small groups and exercises on the personal computer individually. Given the relevance of practical exercises for the achievement of the knowledge and skills objectives of this course, attendance at the lectures is strongly recommended.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 <https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas > on Health and Safety online.

Assessment methods

Student learning is assessed through a written exam divided into two parts:

1. A computer-based exercise involving the processing and analysis of biomechanical data (1 hour and 30 minutes);

2. Open-ended questions on the use of the instruments covered in the course and/or on laboratory activities carried out during the course.

The use of books or notes is not permitted during the exam.

The final grade, expressed on a scale of 30, is based on the evaluation of the first part (60%) and the second part (40%).

 

Students with Specific Learning Disabilities or temporary/permanent disabilities are advised to contact the University Office in charge well in advance, at the following address: https://site.unibo.it/studenti-con-disabilita-e-dsa/en . The Office will assess the need for any possible accommodations, which must be submitted to the course instructor for approval at least 15 days in advance. The instructor will evaluate the request in light of the course's learning objectives.
