NEUROLOGICAL DATABASES

Database of Deep Brain Stimulation on Parkinsonian Tremor - Rest tremor velocity in the index finger of 16 subjects with Parkinson's disease, who receive chronic high frequency electrical deep brain stimulation.

Database : Noise Enhancement of Sensorimotor Function - Measurements of postural sway in 27 healthy volunteers (15 young, 12 elderly), with and without subsensory stimulation of the soles of the feet using mechanical noise.

GAIT DATABASES

Gait Dynamics in Neuro-Degenerative Disease Database - Collection of 64 recordings of gait (including original foot signals) from 15 subjects with Parkinson's disease, 20 with Huntington's disease, 13 with amyotrophic lateral sclerosis, and 16 healthy controls.

Gait in Aging and Disease Database - Data from healthy young and old volunteers, and patients with Parkinson's disease.

Gait Maturation Database - Collection of data from healthy children ages 3-14.

Unconstrained and Metronomic Walking Database - Collection of long-term recordings of gait dynamics from 10 healthy young volunteers.

Gait in Parkinson's Disease - A collection of multichannel recordings from force sensors beneath the feet of 93 patients with Parkinson's Disease, and 73 healthy controls.

DATABASES OF PHYSIOLOGICAL SIGNALS

MGH/MF Waveform Database - Collection of 250 recordings of 3-lead ECGs, ABP, PAP, CVP, respiration, and airway CO2 signals from patients in critical care units; some recordings include intra-cranial, left atrial, ventricular and intra-aortic pressure waveforms.

Stress Recognition in Automobile Drivers - Recordings from healthy volunteers driving on a predefined route including streets and highways; signals recorded include ECG, EMG, galvanic skin resistance, and respiration.

Apnea-ECG Database - Consists of 70 ECG recordings, each typically 8 hours long, with accompanying sleep apnea annotations obtained from study of simultaneously recorded respiration signals, which are included for 8 of the recordings.

Fantasia Database - ECG and respiration recordings, with beat annotations from 20 young and 20 elderly subjects, all healthy, in sinus rhythm during a resting state (two hours each). Half of the recordings also include (uncalibrated) continuous noninvasive blood pressure signals.

MIMIC Database - Contain 72 complete records from this database, together with periodic measurements ("numerics") for all 121 records of the database, including multiple recordings of some of the 90 subjects. The lengths of these records vary, but average about 40 hours each.

MIMIC II Waveform Database - A collection that currently includes 4164 records posted on PhysioNet, containing digitized signals (typically including ECG, ABP, and respiration) and time series of periodic measurements, each presenting a quasi-continuous recording of vital signs of a single patient throughout an ICU stay (typically a few days, but many are several weeks in duration).

MIMIC II Clinical Database - A collection of clinical records that accompany the records of the MIMIC II Waveform Database, containing results of laboratory tests, medications, ICD9 diagnoses, and more. Each record contains data for a single subject, and many records span multiple ICU admissions for the same subject, including available medical history between ICU stays. Portions of 60 records are currently posted.

MIT-BIH Polysomnographic Database - Sleep stage and apnea annotations.

Santa Fe Time Series Competition Data Set B -Data extracted from the MIT-BIH Polysomnographic Database.

Sleep-EDF Database - A collection of sleep recordings from 8 healthy subjects. Each recording contains 2 EEG signals, EOG, and an event marker, and is accompanied by a manually-scored hypnogram. Four recordings also include submental EMG, and the other four recordings also include the submental EMG envelope, oro-nasal airflow, and body temperature.

Sleep Heart Health Study Polysomnography Database - 1000 overnight polysomnograms collected to study the relationship of sleep disordered breathing and cardiovascular disease. Recordings include EEG, EOG, EMG, ECG, nasal airflow and respiratory effort signals, periodic measurements of SaO2 and heart rate, annotations of sleep stages, respiratory events, EEG arousals, and more.

Sleep Apnea Database - Contains 25 full overnight polysomnograms with simultaneous three-channel Holter ECG, from adult subjects with suspected sleep-disordered breathing.

PhysioNet - Research resource for complex physioloical signals

PhysioNet offers free access via the web to large collections of recorded physiologic signals and related open-source software.

The PhysioNet Resource, intended to stimulate current research and new investigations in the study of complex biomedical and physiologic signals, has three closely interdependent components:

PHYSIOBANK

PhysioBank is a large and growing archive of well-characterized digital recordings of physiologic signals and related data for use by the biomedical research community. PhysioBank currently includes databases of multi-parameter cardiopulmonary, neural, and other biomedical signals from healthy subjects and patients with a variety of conditions with major public health implications, including sudden cardiac death, congestive heart failure, epilepsy, gait disorders, sleep apnea, and aging. These collections include data from a wide range of studies, as developed and contributed by members of the research community. To begin an exploration of PhysioBank, start here.

PHYSIOTOOLKIT

PhysioToolkit is a large and growing library of software for physiologic signal processing and analysis, detection of physiologically significant events using both classical techniques and novel methods based on statistical physics and nonlinear dynamics, interactive display and characterization of signals, creation of new databases, simulation of physiologic and other signals, quantitative evaluation and comparison of analysis methods, and analysis of nonequilibrium and nonstationary processes. A unifying theme of many of the research projects that contribute software to PhysioToolkit is the extraction of "hidden" information from biomedical signals, information that may have diagnostic or prognostic value in medicine, or explanatory or predictive power in basic research. All PhysioToolkit software is available in source form under the GNU General Public License (GPL). To learn more about the contents of PhysioToolkit, begin here.

PHYSIONET

PhysioNet is not only the name of the Resource, but also of its web site, physionet.org. The PhysioNet web site was established by the Resource as its mechanism for free and open dissemination and exchange of recorded biomedical signals and open-source software for analyzing them, by providing facilities for cooperative analysis of data and evaluation of proposed new algorithms. In addition to providing free electronic access to PhysioBank data and PhysioToolkit software, the PhysioNet web site offers service and training via on-line tutorials to assist users at entry and more advanced levels. In cooperation with the annual Computers in Cardiology conference, PhysioNet hosts a series of challenges, in which researchers and students address unsolved problems of clinical or basic scientific interest using data and software provided by PhysioNet.
