2.2. In-Person Assessment Process
STAGGERED
Participants were scheduled for a 60 min assessment appointment in a multi-purpose room in a community center where the research team delivered all assessments following standardized communication scripts. Prior to the assessment appointment, the room was arranged for testing with consistent room temperature and lighting. Testing stations in the room were laid out in a sequenced manner around the perimeter of the room. Participants started by completing height and weight measurements using a calibrated scale and a wall stadiometer. Participants then progressed through the functional fitness assessments in the following order: SPPB balance tasks (1 trial for feet together, staggered stance (1 right-foot-forward and 1 left-foot-forward trial) and tandem stance conditions (1 right-foot-forward and 1 left-foot-forward trial), 30-Second Chair Stand Test (1 trial), 8 Foot Up-and-Go Test (Single Task—2 trials), 8 Foot Up-and-Go Test (Dual Task—1 trial), 30 s Arm Curl Test (1 trial), and 2 min Step Test (1 trial).
