A method for reliability analysis of speed-related repeated measures gait data.
Reliability should be addressed for measures used in gait studies. Many protocols designed for experimental or clinical research request subjects to walk repeatedly at different steady-state walking speeds. Such data lend themselves to reliability analysis, rendering a separate reliability test session superfluous. Thus human and time resources are saved, and the reported reliability relates directly to the study population and occasion at hand. In this report a procedure is introduced where residuals from individual speed related curve estimates are regarded as measurement error. If there is no speed related trend in data, the procedure will yield identical results to a usual repeated measures reliability analysis where all within-subject variability is regarded as measurement error.
