“…Schmiegel et al [22] evaluated the foot pressure of 112 subjects with RA and observed that pedobarography did not score the highest-pressure values in the areas of severe pain suggesting that it could be unable to detect patient's habit of avoiding pressure in the area of pain (antalgic gait). Telfer et al [23] did not observe significant changes in plantar pressure caused by orthotic interventions in a group of 15 patients with long time RA. The fact that our sample consisted most of patients with long time disease, with well-established and diverse deformities probably have influenced the results tours a non significant effect in plantar pressure reduction.…”

“…Options are available to include or remove sensors that are only partially covered by the mask in the analysis. The package also implements other pressure variables reported in the scientific literature like center of pressure excursion index 20 and dynamic plantar loading index (DPLI, also known as regression factor (RF) index) 21 , which have been used to indicate characteristics like foot posture 22 and abnormal foot function 23 . For regional analysis, certain metrics like pressure time integral have been calculated in a variety of ways, changing how data is meant to be interpreted.…”

In many biomechanical analyses, the forces acting on a body during dynamic and static activities are often simplified as point loads. However, it is usually more accurate to characterize these forces as distributed loads, varying in magnitude and direction, over a given contact area. Evaluating these pressure distributions while they are applied to different parts of the body can provide effective insights for clinicians and researchers when studying health and disease conditions, for example when investigating the biomechanical factors that may lead to plantar ulceration in diabetic foot disease. At present, most processing and analysis for pressure data is performed using proprietary software, limiting reproducibility, transparency, and consistency across different studies. This paper describes an open-source software package, ‘pressuRe’, which is built in the freely available R statistical computing environment and is designed to process, analyze, and visualize pressure data collected on a range of different hardware systems in a standardized manner. We demonstrate the use of the package on pressure dataset from patients with diabetic foot disease, comparing pressure variables between those with longer and shorter durations of the disease. The results matched closely with those from commercially available software, and individuals with longer duration of diabetes were found to have higher forefoot pressures than those with shorter duration. By utilizing R’s powerful and openly available tools for statistical analysis and user customization, this package may be a useful tool for researchers and clinicians studying plantar pressures and other pressure sensor array based biomechanical measurements. With regular updates intended, this package allows for continued improvement and we welcome feedback and future contributions to extend its scope. In this article, we detail the package’s features and functionality.
