LOINC long common name : PhenX - walking - ambulation objective protocol 151001;
LOINC short name : Walking ambulation objective proto;
LOINC description : An accelerometer-based pedometer is used to measure the number of steps over a desirable
measurement period (for a robust assessment of free-living walking, a minimum of 3
days is recommended). The participant is asked to wear the pedometer during all waking
hours of the study period. Data (number of steps per hour or per day) is downloaded
from the pedometer after being retrieved from the participant. The hip placements
of the pedometer (on a belt or in the front pants pocket) have been shown to yield
the best walking assessments. The absolute accuracy (number of steps and or distance)
may vary with different pedometers, data/signal filters used by the devices, and/or
placement locations. Follow manufacturers' operation manuals for specific calibration
procedures if needed. It is generally not recommended to use pedometer-predicted energy
expenditure values.;
