Biomedical Signal Analysis


The functioning of human body can be measured as a function of time by using different kinds of measurement systems. The time series acquired in these measurements are in general called biosignals. The most commonly studied biosignals include the electrocardiogram (ECG) and electroencephalogram (EEG) which are measurements of electrical activities of the heart and the brain, respectively. The analysis of biosignals is challenging, because extraction of useful information from these signals often necessitates complex mathematical models as well as knowledge of the underlying human physiology or neurophysiology.

The main research topics of the group are currently human motion analysis, modelling of motor control in Parkinson’s disease, cardiovascular signal analysis methods, and psychophysiological measurements in assessing human behaviour and health. The research group has state-of-the art laboratory facilities at the Campus area of the University (Kuopio campus). The facilities include human motion, human performance laboratories, as well as a driving simulator and robot-assisted rehabilitation facilities.

The research group is constantly involved in several nationally and internationally funded projects, and the collaboration with clinical and industrial partners is very intensive.
