Learning outcomes

The aim of this course is to provide basic skills of biology, biochemistry, physics and statistics, main-ly focusing on the most useful aspects for understanding and investigating biomedical problems as-sociated with physiotherapy and to provide the foundations of the experimental method for modern scientific and technological disciplines, to get students consolidate scientific accuracy and critical evaluation of experimental data. At the end of the course students will have reached the necessary skills to understand, describe and analyse natural, biological and physical phenomena, regarding bi-omedical issues. Students will be able to explain molecular and cellular mechanisms of the human body and to understand the pathogenic meaning of alterations. Students will be able to report topics related to aforementioned fields in a precise way, with critical evaluation and appropriate scientific language. Finally, students will have developed abilities to approach further topics, which will be part of next year courses, with good autonomy. APPLIED PHYSICS: The aim is to provide basic knowledge of physical quantity and fundamental laws of physics, par-ticularly of mechanics and its applications within biomedical phenomena and real situations. To ac-quire the ability to solve simple exercises of physics, mostly referring to biomechanical concepts, al-so applied to practical situations. BIOCHEMISTRY: to provide basic knowledge of organic chemistry and biochemistry, the relation between structure and function of the main biological macromolecular classes, molecular-metabolic regulation, the interconnections between biochemical processes and energetic transformations. APPLIED BIOLOGY: to provide knowledge of biology and human genetics in an evolutionary vi-sion related to the structural, functional and molecular characteristics of cellular processes of living organisms and a focus on basic mechanisms that set up cellular activity, reproduction, interaction and transmission of the normal and pathological hereditary traits in humans. DESCRIPTIVE STATISTICS: to provide bio-statistical knowledge, focusing on basic statistic methods for biomedical data analysis such as methods for collecting and summarizing clinical or ep-idemiological research data, probability calculations, generalizing the information collected on a sample to the population of origin, a graphic summary representation and interpretation of the main statistical results.

Assessment methods and criteria

The exam consists of 4 written tests, one for each module, based on all the issues covered throughout the course. Tests can be passed separately as long as they are taken within the same academic year. For each academic year, 6 periods are available to take the exams: 2 in the Winter Session at the end of the course, 2 in the Summer Session and 2 in the Autumn Session. In order to gain access to the biology test, students must have first discharged any training debts relating to the minimum biology, chemistry and physics knowledge.
To pass the exam, students must get a score of not less than 18/30 in each test. The final mark (/out of 30) willl derive from the weighted average over credits of each single test score. Students can retire or refuse the proposed score: in such case, any partial credit will be canceled and the students shall enroll again for the whole examination (all the 4 tests).
