“…In clinical settings, this usually occurs during prolonged periods of immobility (e.g., in wheelchair sitting, intensive care stays) or use of prosthetics . In the lying body position, PUs most frequently occur at the so‐called predilection sites, like the sacral and lateral heel skin areas . Aged patients are especially prone to PU development because of the declining structural and functional capacities of the skin and underlying tissues, including for example, tissue stiffening, flattening of dermo‐epidermal junction, impaired perfusion, and slower repair …”

Pressure ulcers (PUs) are injuries to the skin and underlying tissues, caused by sustained deformations and occur frequently in aged patients. Skin microtopography and stiffness affect the interaction of skin with contact surfaces contributing to PU development. We simulated immobility in 20 healthy females (mean age 69.9 years). Skin microtopography and stiffness were measured at the PU predilection sites before and after loading. Skin roughness decreased at the heels by 18.1% after 90 minutes (p = 0.022), but remained unchanged at the sacrum and the upper back. Structural elasticity and elastic deformations increased at all skin areas; changes over time were significant at the sacrum (p = 0.005) and the heel, (p = 0.002). The residual skin deformation increased at all skin areas after loading significantly at the sacrum (32.0%, p = 0.013) and upper back (20.6%, p = 0.007). The structural "biological" elasticity of the skin decreased significantly at the upper back after loading, but remained unchanged at the heels. All skin changes recovered after unloading. Results indicate that prolonged loading causes structural skin changes in humans in vivo in PU predilection sites. The pathogenesis of PUs is different at the heels, the sacral and upper back skin.

Patients in an immobile state are susceptible to pressure ulcers, which are localized injuries to the skin and/or underlying tissues due to prolonged pressure. This paper builds upon a body of work examining in-hospital older adult patients at-risk of developing pedal pressure ulcers by examining thermal images of one patient, who was reporting pain in her right foot, over 112 days of a hospital stay. Thermal images of the patient's left and right heels and malleoli were subjected to image processing to remove noise and enhance contrast, region selection and feature extraction to observe changes in temperature over time. Mean intensity within each ROI was extracted, and the difference in temperature between the left and right heels was calculated over time. The resulting temperature pattern was consistent with the physical phenomenon related to ulcer development, intervention and recovery; the right heel was similar in temperature when starting the study and at the end of the study, but was drastically warmer when experiencing erythema and drastically colder when experiencing ischaemia. These results suggest that consistent thermal imaging, in conjunction with image processing may be able to detect the formation of pressure ulcers faster than can be visually observed. Early detection of pressure ulcers is critical in the prevention of pressure ulcers, and is of great importance to any hospital or nursing home.
