This study aimed to develop a fall prediction model for older adults by measuring the multi-faceted biosignal data to classify the walking patterns and by identifying causal relationships with the variables that affect the fall.

Gait analysis
Gait analysis is a process of measuring and evaluating the walking patterns of patients by using surface electromyograph and motion analysis system. All participants perform overground walking to assess the change of kinematic, kinetic and muscle activation using a motion analysis and surface EMG
Time frame: 1 hour
Change on metabolic energy expenditure
All subjects underwent measurements respiratory metabolism energy during treadmill walking at a comfortable speed for 5 minutes. It assess the change of metabolic energy expenditure using a portable cardiopulmonary metabolic system (Cosmed K4b², Rome, Italy).
Time frame: 15 minutes
Change on muscle activity
All subjects underwent measurements of muscle activity during treadmill walking at a comfortable speed for 5 minutes
Time frame: 30 minutes
Change on brain activity
All subjects underwent measurements of brain activity by measuring fNIRS during treadmill walking at a comfortable speed and high speed for 5 minutes
Time frame: 30 minutes
Short Physical Performance Battery (SPPB)
The Short Physical Performance Battery (SPPB) is a series of tests used to evaluate lower extremity function and mobility in older people.
Time frame: 5 minutes
Four Square Step Test (FSST)
The Four Square Step Test (FSST) is used to assess dynamic stability and the ability of the subject to step over low objects forward, sideways, and backward.
Time frame: 5 minutes

The Timed Up and Go test (TUG)
The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance. It uses the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.
Time frame: 5 minutes
10 meter walk test (10MWT)
Measure of self selected speeds by measuring the time it takes an individual to walk 10 meters. To perform the test, patient walks 10 meters (33 ft) and the time is measured when the leading foot crosses the start line and the finish line. The instructions are: "Please walk this distance at your normal pace when I say go."
Time frame: 5 minutes
Modified Bathel index (MBI)
The MBI is a measure of activities of daily living, which shows the degree of independence of a patient from any assistance. It covers 10 domains of functioning (activities): bowel control, bladder control, as well as help with grooming, toilet use, feeding, transfers, walking, dressing, climbing stairs, and bathing.
Time frame: 5 minutes
6 minutes walking test (6MWT)
The six-minute walk test (6MWT) measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes.
Time frame: 6 minutes
Fall Efficacy Scale (FES)
The Falls Efficacy Scale (FES) is a ten-item test rated on a 10-point scale from not confident at all to completely confident.
Time frame: 5 minutes
