Evaluation of Materials for the Distribution of Pressure in the Treatment of Neuroischemic Ulcers

26 de mayo de 2026 actualizado por: Iván Julián Rochina, University of Valencia

The hypothesis of this study is based on the premise that pressure-distributing materials with superior biomechanical and tissue response properties will be capable of improving the healing rate of neuropathic ulcers.

The overarching objective of the present project is to assess the influence of the nature and method of application of the materials under study on tissue response, the reduction of pressure on the sole of the foot, and the healing of neuropathic ulcers in patients with diabetes mellitus.

Descripción detallada

The study is divided into two distinct phases:

The following analysis is concerned with the characteristics of materials that are employed for the purpose of the distribution of pressure. This will entail the meticulous analysis of the response exhibited by the materials, with the objective of ascertaining their true biomechanical behaviour in volunteers devoid of active ulcers.

The materials selected in the first part will be applied for the treatment of revascularised neuroischaemic ulcers. This will determine which of the materials is the most suitable for treating the lesion.

Experimental: felt padding
The 5 mm and 10 mm felt pads are applied for 4 days.
The 5 mm felt pad is applied for 4 days and then removed. After allowing the skin at least 48 hours to recover, the 10 mm felt pad is applied, also for 4 days.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Near-infrared perfusion index (NIR perfusion)
Periodo de tiempo: Baseline and 4 days
Hyperspectral imaging was performed using the TIVITA® 2.0 camera (Diaspective Vision GmbH, Germany). This non-contact, non-invasive device captures images across multiple wavelengths within the visible and near-infrared spectrum (500-1000 nm), enabling assessment of microcirculatory parameters up to a tissue depth of approximately 8 mm. The device provides an image resolution of 640 × 480 pixels, with an acquisition time of 6.4 seconds. Images were analyzed using TIVITA® Suite software by selecting a circular region of interest adjusted to the metatarsal head and offloading area under study.
Baseline and 4 days

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Thermography
Periodo de tiempo: Baseline and 4 days
The images will be captured using the FLIR C8 thermal imaging camera. The camera in question features a true thermal resolution of 320 × 240 pixels (76,800 measurement points) and MSX® technology, which combines visual and thermal details into a single image, thereby facilitating the detection of anatomical abnormalities. Thermographic variables of interest included differences in absolute temperature values (maximum and mean temperature) within the region of interest corresponding to the offloading area.
Baseline and 4 days
Peak pressure (Pmax)
Periodo de tiempo: Baseline and 4 days

Peak pressure (Pmax) measured at the metatarsal head corresponding to the highest dynamic pressure.

Plantar pressures were assessed using the EPS+R platform (Loran Engineering®, Bologna, Italy). The platform measures 50 × 70 × 4 mm, weighs 7 kg, and incorporates 2304 resistive sensors measuring 9 × 9 mm each. The pressure range is 50-350 kPa, with a maximum acquisition frequency of 100 Hz.

Biomech® Studio 2019 software (LetSense Srl, Loran Engineering®) was used for data analysis.
