“…In relation to this study, the average value of Pmax exerted and recorded in the area of the ischium in a sitting position was 85.7  29.8 mm Hg in the sedentary group and 87.7  23.2 mm Hg in the physically active group. Thus, the IT-area pressure on the pad-user interface greatly exceeded recommended values [20,64]. In this situation, the excessive use of a wheelchair, but without any corresponding changes in posture, significantly increases the risk of PUs [63].…”

“…Pressure distribution at the user-cushion interface was first measured in static pressure with the Xsensor 3p pad ( Figure 5). Cushion inflation pressure was optimized for participants by regulating the inflation pressure of both chambers of the Xsensor 3p pad and following the protocol described previously [20]. Before the study began, the seat pressure mat was calibrated according to the manufacturer's instruction.…”

“…For the individual characterization of the mechanical pressure of the wheelchair cushion, the measure of the interface pressure between the person and the seating surface is the most common test performed in clinical settings [14,[19][20]. However, the mechanical properties are not the only characterizations that indicate the risk of tissue damage.…”

“…Therefore, maintaining adequate oxygen pressure (PO2) is harder in those areas below the lesion, such as the ischial tuberosities (IT), which increases the risk of PU and warrants a multimodal assessment establishing the functional characteristics of wheelchair cushions. The consequences of mechanical pressure on vascular flow at the areas of risk should be added to the interface pressure between the person and the seating surface [20].…”

Abstract-This pilot study proposed a method for assessing the status of vascular flow measured by transcutaneous oxygen pressure (TcPO2) in the area of the ischium in people with spinal cord injury (SCI). In a sample of 38 men (two groups: 12 physically active and 26 sedentary) with thoracic SCI, the distribution of the physiological response of the tissues under load during sitting was assessed through analysis of ischium TcPO2 values obtained by an oximeter. TcPO2 baseline, recovery time of TcPO2 after sitting (Trec), the percentage of TcPO2 (%TcPO2) of maximum pressure TcPO2, and mechanic maximal pressure (Pmax) were evaluated. Trec in the physically active group was significantly lower (p < 0.05) than in the sedentary group. Likewise, significant differences in %TcPO2 between groups (p < 0.05) were also found. We concluded that the physiological response of the tissues under an individual with SCI's own weight resulting from prolonged sitting is better in those who are physically active.

“…The materials have many characteristics and can be used for improving stability, positioning, comfort and prevention of ulcers. 9 Takara et al 10 did not observe the influence of gel and foam cushions on balance during the seated position in individuals with paraplegia. However, it is not known if these types of cushion can accentuate the misalignment posture occurs due to the muscular deficit observed in subjects with SCI.…”

Methods: Eight individuals, four paraplegics and four tetraplegics with SCI and 20 healthy individuals participated in the study. Photos were taken of individuals in the sitting position using foam, gel cushions and with no cushion. They were analyzed using the PAS/SAPO. The alignment of the anterior-superior iliac spine (ASIS) and the posterior pelvic tilt were evaluated from the angle formed between the ASIS and the greater trochanter of the femur. Results: The group of healthy individuals presented the best postural alignment when compared with the group with SCI, both for the ASIS alignment (Po0.05) and for the degree of posterior pelvic tilt (Po0.05). No significant differences were found in the variables analyzed when the seat cushions were compared. Conclusion: The different types of cushions did not alter the sitting posture; however, individuals with SCI showed worse postural alignment than the healthy individuals. PAS/SAPO was demonstrated to be useful for postural assessment.

Background Pressure ulcers (i.e. bedsores, pressure sores, decubitus ulcers) are areas of localised damage to the skin and underlying tissue. They are common in the elderly and immobile, and costly in financial and human terms. Pressure-relieving support surfaces (i.e. beds, mattresses, seat cushions etc) are used to help prevent ulcer development. Objectives This systematic review seeks to establish: (1) the extent to which pressure-relieving support surfaces reduce the incidence of pressure ulcers compared with standard support surfaces, and, (2) their comparative effectiveness in ulcer prevention.
