Pressure measurement devices: from technical assessment to clinical performance
Journal of Foot and Ankle Research volume 5, Article number: P8 (2012)
Technical assessment of pressure measurement devices (PMDs) should guarantee for their appropriate use in the clinics. The study aims at proving the validity of the assessment methodology ISS proposed , and at quantifying the impact of PMD performance on clinical assessment.
Materials and methods
Three commercial PMDs were first assessed and then compared during barefoot walking: PMDa and PMDb - resistive technology, 1sens/cm2 – were assessed on-site, while PMDc – capacitive technology, 4sens/cm2 - was tested on-the-bench and on-site . The PMDs were aligned on the floor to capture successive at-regimen steps of the left foot of one trained volunteer; 10 complete steps were acquired in both directions for each PMD; data were temporally normalised and averaged; main kinetic parameters were extracted.
To conclude: i) on-site assessment up to 250kPa proved to be necessary but not sufficient to guarantee for a good PMD performance during gait; ii) a thorough on-the-bench assessment is effective and recommended; iii) use of PMDb data might be misleading in research and risky in the clinics. The study is going on with the comparison among other commercial PMDs and under a wide range of testing conditions.
