The HBEDB contains force platform recordings from subjects undergoing stabilography tests. The subjects performed standing tasks under four different conditions: with their eyes opened or closed, while standing on a rigid or unstable surface. Each condition was tested three times, with the order of the conditions being randomized among subjects. A total of 1930 trials performed by 163 different subjects are given in this database.
Each 1 minute recording is sampled at 100Hz and low pass filtered at 10Hz. The signal files contain 8 channels with 3 different recording types:
- Force/N - (x, y and z)
- Moment/Nm - (x, y and z)
- Center-of-Pressure/cm - (x and y)
The signal file names are in the form BDS0XXXX, where XXXX is the trial number.
The following qualitative tests were employed on each subject:
- Short Falls Efficacy Scale International
- International Physical Activity Questionnaire Short Version
- Trail Making Test
- Mini Balance Evaluation Systems Tests
The subjects were also interviewed about some of their socio-cultural, demographic, and health information, including their age, medications, and illnesses. The collected information and the results of the tests are given in the BDSinfo.txt and BDSinfo.xlsx files. Each record's header file also contains some of these subject fields.
