Parkinson

The second most common neurodegenerative disease is Parkinson’s disease (PD). PD is a chronic and progressive ailment in which the brain is unable to control body movement. Typical symptoms of PD include resting tremor, bradykinesia, and postural instability. Although medications have been helpful in treating PD symptoms, currently, there is no cure for PD and […]

Hemorrhage

Over 40% of deaths within 24 hours of a traumatic injury are due to hemorrhage1. The early application of life saving interventions, before the development of circulatory shock, is a priority in dealing with hemorrhage. Mortality can be significantly reduced when patients needing immediate care can be identified early. Traditionally patients are diagnosed based on […]

Concussion

Concussion, also referred as mild traumatic brain injury is one of the most common occurrences in high impact games like football, ice hockey, rugby as well as other fast spaced sports. According to the CDC, between 2001 and 2009, an estimated 173,285 people under age 19 were treated in hospital emergency rooms for concussion related […]

Cardio-Postural Interaction

The  focus  of  our  work  on  cardio-postural  analysis  is  to  establish  a  cause  and  effect  relationship  between cardiovascular and postural variables. Previous research indicates that cardiovascular and postural system interacts with each other to maintain equilibrium, however, cause and effect relationship between such systems is yet to be established. A statistical Granger causality test was […]

Cardiac Vibration Signals

The  pulsatile  phenomena  of  the  body’s  surface  with  every  heart beat  have  attracted  the  attention  of physicians since the beginning of medicine. Precordial examination or cardiac examination is performed as part of the regular physical examination for the purpose of the detection of cardiovascular pathologies. These  tests  include  palpation  and  auscultation.  With  palpation,  the  pulsations […]

Brain Computer Interface

Brain-computer interface (BCI) systems enable the human brain to communicate with an external device bypassing the explicit pathways formed by natural nervous system. BCI decodes EEG signals recorded from the brain to extract important signatures related to subject’s intention. There are different EEG-based BCI systems such as P300 or steady-state visual evoked potential (SSVEP) are […]

Respiration Analysis of SCG

Respiration affects the cardiovascular system significantly and this is observed in hemodynamic parameters such as stroke volume and heart rate. The morphology of signals relevant to the heart also changes with respiration. Such changes have been used to extract respiration signal from the electrocardiogram (ECG). It is also shown that accelerometers placed on the body […]
