Lying Posture Classification for Pressure Ulcer Prevention

Abstract

Pressure ulcers are a common problem among patients with limited mobility, such as those bedbound and wheelchair-bound. Constant and prolonged applied pressure is one of the extrinsic factors contributing to the development of pressure ulcers. Analyzing lying postures together with interface pressure measurements from a pressure sensitive bed helps revealing pressure hot spots that can potentially lead to pressure ulcer development. We propose an intelligent system that features lying posture classification with pressure hot spots identification based on interface pressure measurements to possibly identify potential pressure ulcer risk and to provide effective preventive measures. Experimental outcomes correctly classify different lying postures with an accuracy of up to 93%. The proposed system is expected to assist caregivers to detect risk evidence and to provide timely and appropriate interventions for effective pressure ulcer prevention.

Sleep quality, sleeping postures, and sleeping equipmentin patients with ankylosing spondylitis

“…Apart from these, others were classified as 'other sleeping postures' (31,32). The sleeping postures of each participant were recorded.…”

Approaches that use software to support the prevention of pressure ulcer: A systematic review

“…They are installed along the mattress and can identify the amount of pressure exerted on them by the patient's body. This technology is used by twenty-six of the approaches, more specifically, the ones presented in [2,14,7,23,21,6,39,15,35,34,27,28,41,40,4,11,13,26,36,17,37,12,9,22,20,5].…”

“…Eleven approaches provide reports that show the body position of the patient in bed [38,34,27,28,41,40,13,26,36,37,20]. Such reports are obtained by using classification algorithms that estimate the position based on the intensity data of the pressure sensors installed on the mattress.…”

“…Effectiveness was issued in twelve of the selected articles: [16,6,15,34,18,27,41,40,26,36,17,28]. Yet, no randomized control trials were applied to verify the approach effectiveness.…”

Multimodal Sleeping Posture Classification

“…One is to infer the internal human bio-status such as sleep-wake classification and sleep quality assessment [1,3,7,10] and another is to find the external sleeping pattern including the position, posture and duration [4,11]. In this paper we focus on sleeping posture classification, which can be important not only for bedsore prevention [14,17] but also for sleeping quality analysis [2].…”
