چکیده انگلیسی


- A new method has been developed to organize the discrete sensors of a low-cost plantar pressure system.
- Two sensor layouts have been tested to determine the most accurate for plantar pressure analyses by means of an embedded plantar pressure system.
- Data recorded from the plantar pressure system were compared to those recorded from a force platform.
- Results showed that an optimized sensor layout allows to increase the accuracy of plantar pressure analyses with low-cost systems.
- Accurate data from discrete sensors will enable feedback and long term monitoring using portable systems.

The aim of this study was to determine the distribution of discrete sensors under the footprint for accurate plantar pressure analyses. For this purpose, two different sensor layouts have been tested and compared, to determine which was the most accurate to monitor plantar pressure with wireless devices in research and/or clinical practice. Ten healthy volunteers participated in the study (age range: 23-58 years). The barycenter of pressures (BoP) determined from the plantar pressure system (W-inshoe®) was compared to the center of pressures (CoP) determined from a force platform (AMTI) in the medial-lateral (ML) and anterior-posterior (AP) directions. Then, the vertical ground reaction force (vGRF) obtained from both W-inshoe® and force platform was compared for both layouts for each subject. The BoP and vGRF determined from the plantar pressure system data showed good correlation (SCC) with those determined from the force platform data, notably for the second sensor organization (ML SCC= 0.95; AP SCC = 0.99; vGRF SCC = 0.91). The study demonstrates that an adjusted placement of removable sensors is key to accurate plantar pressure analyses. These results are promising for a plantar pressure recording outside clinical or laboratory settings, for long time monitoring, real time feedback or for whatever activity requiring a low-cost system.
