“…Two studies [31,35] recruited both able-bodied and disabled participants, with respectively 20 (10 able-bodied, 10 SCI (spinal cord injury)) and 8 (1 SCI, 3 spina bifida, 2 orthopaedics, 1 amputee and 1 able-bodied) participants. The 6 other studies recruited only disabled participants, with respectively 1 (cerebral palsy), 15 (SCI), 10 (SCI), 8 (6 SCI and 2 multiple sclerosis), 15 (hemiplegia) and 10 (SCI) participants [28][29][30]32,33,38].

Background: The increasing number of wheelchair users and their risk of medical complications such as pressure ulcers (PU) make it important to have a better understanding of their seating characteristics. However, while most studies tackling this issue are based on static measurements, wheelchair users are active in their wheelchairs when performing daily life activities. This suggests the need to assess the mechanical loads at the wheelchair user's bodyseat interface during dynamic activities.Objectives: A scoping review was conducted to explore the existing data (shear load and pressure) and highlight significant parameters, relevant conditions and methodological strategies when studying wheelchair users performing a dynamic task.Materials and methods: The literature search was performed by applying the PRISMA methodology.Results: 11 articles met the inclusion criteria. Differences between static and dynamic data were found in the literature for peak pressure values, for pressure distribution and in location of peak pressure. None measured tangential load at the seat/body interface, although two studies measured the shift of the ischial region. A significant impact of type of pathology has been quantified, showing the need to perform experimental 2 studies on diverse populations. The protocol and the pressure parameters studied were very diverse.Conclusion: Further studies carefully choosing interface pressure mapping parameters and investigating a broader range of pathologies are required. Additionally, researchers should focus on finding a way to measure seated tangential load.

“…3 PIs mainly occur over bony prominences at the heel, ankles, sides of the knees, toes and feet, and particularly in the pelvic region which includes the sacrum, coccyx (tailbone), trochanter (hip bone), and ischium (sitting erect bone) (Figure 1(a)). 6 The National Pressure Ulcer Advisory Panel (NPUAP) 7 has developed a widely accepted PI staging system that delineates various grades of PI degeneration (Figure 1(b)). As a rule, grade I and grade II PI can be treated nonoperatively whereas grade III and grade IV often require surgical intervention.…”

The high recurrence and complications associated with severe pressure injuries (PI) necessitate the exploration of advanced treatments, such as cell-based therapies, to facilitate wound healing. Such techniques harness the ability of different cell types to promote angiogenesis, re-epithelialization of the skin, and tissue regeneration. This systematic review explores the efficacy of cell-based therapies and tissue engineering in treating deep PI. We searched for interventional studies using cells in the treatment of PI in adults in four online libraries (PubMed, Embase, Ovid Medline, and Cochrane; latest search 10th June 2023). We found one randomized clinical trial (RCT), two non-RCT, and three pre-post studies, comprising 481 study participants with PI (253 intervention/228 controls). The risk of bias was categorized as moderate due to minimal bias in outcome measurements, or high owing to unclear patient randomization methods, as assessed by the ROBINS-I, NIH, and RoB-2 tools. Four cell types were identified in the context of cell-based therapies of PI: bone marrow mononuclear stem cells (BM-MNCs, n = 2); hematopoietic derived stem cells (HSC, n = 1); macrophages and activated macrophage suspensions (AMS, n = 2); and cryopreserved placental membrane containing viable cells (vCPM, n = 1). Wound healing outcomes were observed in patients undergoing cell-based therapies, including complete wound closure (AMS, vCPM; n = 142), faster healing rate (BM-MNCs, AMS; n = 146), improved granulation tissue formation (HSC, n = 3) and shorter hospitalization time (BM-MNCs; n = 108) compared to standard of care, with no adverse reactions. PI healing rate decreased only in one study with BM-MNC therapy, compared to control ( n = 86). Based on the available data, though with limited evidence, it seems that macrophage deployment showed the most favorable outcomes. The results indicate that cell-based therapies offer a potential avenue for enhancing wound healing and tissue repair in PI; however, more extensive research is needed in this domain.

“…Thus, it is crucial to prevent ischial pressure injury development and recurrence. Therefore, some studies have compared the seating pressure distribution effects of seating cushions [7] [8] and the effects of back support and the reclining wheelchair angle on buttock pressure [9] [10] [11] to prevent ischial and sacral pressure injuries. However, these studies assessed buttock pressure in a sedentary sitting posture, and the pressure distribution during wheelchair maneuvering is unclear.…”

Pressure injuries are frequent secondary complications that occur in patients with Spinal Cord Injury (SCI), and the recurrence rate of ischial pressure injury is highest in SCI patients. Most SCI patients use wheelchairs, and some studies have shown a relationship between buttock pressure and sitting posture. However, the pressure distribution during wheelchair maneuvering is unclear. We measured and compared the shift of the ischial region when maneuvering a standard wheelchair or electric wheelchair in healthy adults. The subjects drove wheelchairs on a flat ground of 10 m and the shift of ischial region was measured with a pressure distribution-measuring device. The ischial region shifted forward or backward while maneuvering both the standard wheelchair and the electric wheelchair, and the shift rate of the ischial region was not significantly different between the standard wheelchair and the electric wheelchair. The ischial region shift occurred when the forward head moved by the video while maneuvering both a standard wheelchair and an electric wheelchair. Therefore, the shift might occurred because the pelvis shifted forward in conjunction with head movement during maneuvering of both the standard wheelchair and the electric wheelchair. This result showed that it is important to reduce head and trunk movements when maneuvering a wheelchair to reduce the shear force on the buttocks and prevent pressure injuries.
