Abstract

In clinical gait analysis, it is challenging to acquire usable force plate data for a patient in a limited amount of time. The aim of this study was to compare three measurement protocols, to investigate if any one of them was more time-efficient than the others at collecting kinetic data. Three conditions were compared for 15 orthopaedic patients: 1) approaching the force plate with four steps, 2) approaching the force plate with six steps, and 3) approaching the force plate with four steps while stepping on a target one step before the first force plate. Then, the following characteristics were analysed: the rate of usable force plate steps, the spatio-temporal parameters, the full-body gait kinematics, and the lower body kinetics. For the condition with four steps and targeting, the rate of usable force plate steps was highest: 84% (6.8 usable trials out of 8.1 trials on average per patient). Left hip adduction and rotation, right shoulder flexion, and total left hip power were the gait parameters with statistically significant differences between the four and six step approach. Left cadence, right step time, left thorax lateroflexion, left shoulder abduction, total right knee power, hip rotation, thorax tilt, and head tilt on both sides were statistically different between the four step approach with targeting and without targeting. None of the differences in gait parameters (except for head tilt) were of clinical relevance. Therefore, approaching the force plate with four steps and stepping on a foot-sized target one step prior to stepping on the force plate increases the rate of usable kinetic data.
