Biosignal
Biosignal refers to a signal that is produced by a biological system and can be measured and analyzed. Biosignals are often used in medical fields to provide valuable information about the health status of an individual. They can be classified into two main types: bioelectric signals and biomechanical signals.
Bioelectric Signals[edit | edit source]
Bioelectric signals are electrical signals produced by the body. They are typically generated by a group of cells that have an electrical potential difference. Examples of bioelectric signals include electrocardiogram (ECG), electroencephalogram (EEG), and electromyogram (EMG).
Electrocardiogram (ECG)[edit | edit source]
An electrocardiogram (ECG) is a bioelectric signal that measures the electrical activity of the heart. It is used to diagnose various heart conditions, such as arrhythmia, myocardial infarction, and heart failure.
Electroencephalogram (EEG)[edit | edit source]
An electroencephalogram (EEG) is a bioelectric signal that measures the electrical activity of the brain. It is used to diagnose neurological disorders, such as epilepsy, sleep disorders, and brain tumors.
Electromyogram (EMG)[edit | edit source]
An electromyogram (EMG) is a bioelectric signal that measures the electrical activity of muscles. It is used to diagnose neuromuscular disorders, such as muscular dystrophy, myasthenia gravis, and motor neuron disease.
Biomechanical Signals[edit | edit source]
Biomechanical signals are mechanical signals produced by the body. They are typically generated by the movement of body parts. Examples of biomechanical signals include gait analysis, respiratory mechanics, and cardiac mechanics.
Gait Analysis[edit | edit source]
Gait analysis is a biomechanical signal that measures the movement of the body during walking. It is used to diagnose movement disorders, such as Parkinson's disease, cerebral palsy, and stroke.
Respiratory Mechanics[edit | edit source]
Respiratory mechanics is a biomechanical signal that measures the movement of the chest and abdomen during breathing. It is used to diagnose respiratory disorders, such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.
Cardiac Mechanics[edit | edit source]
Cardiac mechanics is a biomechanical signal that measures the movement of the heart during the cardiac cycle. It is used to diagnose heart conditions, such as heart failure, valvular heart disease, and cardiomyopathy.
