Abstract

The LTMM database contains 3-day 3D accelerometer recordings of 71 elder community residents, used to study gait, stability, and fall risk.

Subjects

Seventy-one community-living elder adults (mean age = 78.36 ± 4.71 years; range = 65-87 years) were studied. Subjects were included if they were not previously clinically diagnosed with any gait or balance disorders, and if they were cognitively intact, with a Mini-Mental State Examination score above 24 points. Subjects were classified as fallers and nonfallers based on their self-report of previous falls. If subjects had at least 2 falls in the past year, they were considered fallers, otherwise they were considered non-fallers.

Experimental Procedure

The subjects underwent multiple protocols and evaluations:

  1. Clinical and Traditional Fall Risk Assessment: Functional performance based assessments were performed in the laboratory including the Dynamic Gait Index (DGI), the Berg Balance Scale (BBS), the Timed Up and Go test (TUG), and the Four Square Step Test (FSST). The Mini Mental State Examination (MMSE) and the Activities-specific Balance Confidence scale (ABC) were also performed. The results of these afforementioned tests can be found from column 29 of the ClinicalDemogData_COFL.xlsx spreadsheet.
  2. Gait assessment in the Lab: Participants walked for 1 minute at a comfortable, self-selected speed while wearing a gait belt. A 3D accelerometer was worn on the lower back to quantify gait using previously validated methods. The accelerometer files recordings of these tests can be found in the LabWalks directory in MIT format.
  3. Three-day Activities of Daily Living Assessment: After performing tests in the laboratory, participants were asked to wear a 3D accelerometer on their lower back for 3 consecutive days (except during activities like showering or swimming). Subjects received a diary for tracking when and why they took off and put on the device, shown in the ReportHome75h.xlsx spreadsheet. These are the main recordings of this database and can be found in MIT format below.

Files

  1. General Information Files
    • The ClinicalDemogData_COFL.xlsx spreadsheet contains information about the subjects such as their age, gender, and how many times they fell within the last year, and the results of the performed clinical tests.
    • The ReportHome75h.xlsx spreadsheet contains self-reported events by the subjects regarding when and why they put on and removed their accelerometers over their three day recordings.
  2. High Resolution Accelerometer Recording Files
    • The three day 3D accelerometer recordings are in standard MIT format, with each one containing a binary signal (.dat) file and a corresponding header (.hea)file used to interpret the signals. The file names are in the form CO0NN for non-fallers or FO0NN for fallers, where NN is the subject number for that group.
    • The 1 minute lab walk recordings within the LabWalks directory are in the same format as the three day recordings described above. The file names are also in a similar form.
