“…These particular results are in line with Sopher et al, 32 who analyzed gluteal strains and stresses in the buttocks during sitting on flat foam cushions, where FI was present. Experimental work utilizing computed tomography, which has been recently reported by Wu and Bogie, 38 confirms indeed that high FI levels correlate with a history of severe and/or repeated PrUs in subjects with SCI.…”

“…Comprehensive analyses were carried out on data with longitudinal repeated measures and on data averaged over time to find the factors that influence Prl outcomes. Meaningful outcomes were defined as the number of Prl (nPrl) and the percent of IMAT (IMAT%) since IMAT has been found to be a major risk factor for Prl in earlier analysis (7,9). The dichotomized versions of these two outcomes were "with or without pressure injury" (RPrl) and "below or above 15% IMAT" (IMATd).…”

Purpose: To investigate linkages between circulatory adipogenic and myogenic biomarkers, gluteal intramuscular adipose tissue (IMAT), and pressure injury (PrI) history following spinal cord injury (SCI). Methods: This is an observational repeated-measures study of 30 individuals with SCI. Whole blood was collected regularly over 2-3 years. Circulatory adipogenic and myogenic gene expression was determined. IMAT was defined as above/below 15% (IMATd) or percentage (IMAT%). PrI history was defined as recurrent PrI (RPrI) or PrI number (nPrI). Model development used R packages (version 3.5.1). Univariate analysis screened for discriminating genes for downstream multivariate and combined models of averaged and longitudinal data for binary (RPrI/IMATd) and finer scales (nPrI/IMAT%). Results: For adipogenesis, Krüppel-like factor 4 was the top RPrI predictor together with resistin and cyclin D1, and sirtuin 2 was the top IMAT predictor. For myogenesis, the top RPrI predictor was dysferlin 2B, and pyruvate dehydrogenase kinase-4 was the top IMAT predictor together with dystrophin. Conclusion: Circulatory adipogenic and myogenic biomarkers have statistically significant relationships with PrI history and IMAT for persons with SCI. Biomarkers of interest may act synergistically or additively. Variable importance rankings can reveal nonlinear correlations among the predictors. Biomarkers of interest may act synergistically or additively, thus multiple genes may need to be included for prediction with finer distinction.

“…Intrinsic factors include the influences of nutrition, age, injury, and disease, among others [7][8][9][10]. Additionally, recent imaging studies have documented vast variations in buttocks anatomy, tissue type, and quality [11][12], which will also influence the tissue response to loading [13][14]. Magnitude and duration of loading are currently most readily measured in practice.…”

Abstract-The objective of this study was to describe the inseat movement and weight-shifting behavior of full-time wheelchair users. We measured everyday sitting behavior for 192 d across 28 individuals who used manual wheelchairs as their primary mobility device. To obtain the measurements, we used eight thin force sensors placed under participants' wheelchair cushions. On a typical day, participants spent an average of 10.6 +/ 3.0 h in their wheelchair and transferred out of the wheelchair 8.4 +/ 4.3 times. Participants only performed pressure reliefs (90% off-loading of the entire buttocks for at least 15 s) 0.4 +/ 0.5 times per hour they were seated in the chair, but they performed weight shifts (WSs) (30%-90% off-loading of at least one side of the buttocks for 15 s) with a frequency of 2.4 +/ 2.2 times per hour. Despite the higher frequency of WSs, they were not performed in a routine manner. Half of the days studied included one segment of upright sitting lasting at least 2 h without a WS. Given these observations, we conclude that seating evaluations should emphasize positioning individuals in a way that facilitates reaching, leaning, and transferring in a safe manner, not only to improve function but also to affect buttocks loading.
