N2  - Some studies have used load cells (LC) to measure the force applied to horizontal  handrails, but no work has validated an inclined set-up that can be used to bring  new insights into handrail use during staircase gait. The aim of this study was to  validate the accuracy of an inclined handrail set-up instrumented with LC. A  handrail set-up designed to be easily reconstructed and integrating two commercial  LC is proposed. Twenty points were tested along the handrail, with four reference  weights in the three orthogonal directions of the sensors (Medio-Lateral,  Antero-Posterior, Vertical). For each direction, the percentage (%) of error and the  cross-talk between the known and recorded forces were calculated. A linear  regression of the % error was performed to evaluate measurement accuracy in relation  to point of application along the handrail. The current easily replicated set-up of  an inclined handrail showed accurate measures with low cross-talk. The percentage of  error and cross-talk were below 3.7% and 3.7%, respectively, consistent with  previous studies evaluating inclined handrail with other methods. The error and  cross-talk were greater in the Medio-Lateral and Antero-Posterior directions. The  error in the Antero-Posterior direction was larger over the upper part of the  handrail.<p />  <p>Language: en</p>
