Interface shear and pressure characteristics of wheelchair seat cushions.
Pressure ulcer incidence rates have remained constant despite advances in support surface technology. Interface shear stress is recognized as a risk factor for pressure ulcer development and is the focus of many shear reduction technologies incorporated into wheelchair cushions; however, shear reduction has not been quantified in the literature. We evaluated 21 commercial wheelchair seat cushio...
متن کاملComparative biomechanical evaluation of different wheelchair seat cushions.
The aim of the present study was to perform a comparative biomechanical analysis of four antidecubitus wheelchair cushions. Thirty wheelchair users were considered divided into three groups: paraplegic subjects (with no cutaneous sensation), neurologic subjects (with intact cutaneous sensation), and elderly subjects. The biomechanical evaluation was performed using a piezoresistive sensor matri...
متن کاملA randomized clinical trial on preventing pressure ulcers with wheelchair seat cushions.
OBJECTIVES To determine the efficacy of skin protection wheelchair seat cushions in preventing pressure ulcers in the elderly nursing home population. DESIGN Clinical trial with participants assigned at random to a skin protection or segmented foam cushion. Two hundred thirty-two participants were recruited between June 2004 and May 2008 and followed for 6 months or until pressure ulcer incid...
متن کاملCan static interface pressure mapping be used to rank pressure-redistributing cushions for active wheelchair users?
Interface pressure mapping (IPM) is a clinical tool that assists the selection of seat cushions for pressure management for wheelchair users. Clinical pressure measurements are almost always made under static sitting conditions, although this does not consider the time-dependent properties of some cushion materials that may behave differently under the dynamic conditions of self-propulsion. Thi...
متن کاملEffects of different seat cushions on interface pressure distribution: a pilot study
[Purpose] The purpose of this study was to evaluate pressure redistribution on the supporting area of healthy volunteers when using different cushions. [Subjects and Methods] Twenty healthy individuals ranging in age from 19-23 years old and 20 older adults age 60 or above participated in the study. All participants lived in urban communities in South Korea. Group differences according to gende...
