Biomechanical modeling to prevent ischial pressure ulcers.
With 300,000 paraplegic persons only in France, ischial pressure ulcers represent a major public health issue. They result from the buttocks׳ soft tissues compression by the bony prominences. Unfortunately, the current clinical techniques, with - in the best case - embedded pressure sensor mats, are insufficient to prevent them because most are due to high internal strains which can occur even ...
متن کاملDevelopment of a cushion to prevent ischial pressure sores.
A study was carried out jointly by nursing staff and technologists in an attempt to develop a cushion based on scientific principles and measurement that might prevent pressure sores. At each stage in the development clinical trials were carried out, and using the results of these together with the opinions of medical staff and patients who used the cushion the design was suitably modified. Ove...
متن کاملPreventing ischial pressure ulcers: I. Review of neuromuscular electrical stimulation
Objective: Pressure ulcers (PUs) are common and debilitating wounds that arise when immobilized patients cannot shift their weight. Treatment is expensive and recurrence rates are high. Pathophysiological mechanisms include reduced bulk and perfusion of chronically atrophic muscles as well as prolonged occlusion of blood flow to soft tissues from lack of voluntary postural shifting of body weig...
متن کاملPeriodically relieving ischial sitting load to decrease the risk of pressure ulcers.
OBJECTIVE To investigate the relieving effect on interface pressure of an alternate sitting protocol involving a sitting posture that reduces ischial support. DESIGN Repeated measures in 2 protocols on 3 groups of subjects. SETTING Laboratory. PARTICIPANTS Twenty able-bodied persons, 20 persons with paraplegia, and 20 persons with tetraplegia. INTERVENTIONS Two 1-hour protocols were use...
متن کاملNutritional care to prevent and heal pressure ulcers.
Pressure sores are a well-recognized problem, with an etiology that is multifactorial and not solely a consequence of pressure itself. Malnutrition is one of the factors involved, namely low calorie and protein intake. Mainly elderly patients, patients after hip fracture, but also patients after trauma, burns or extended surgery require additional nutritional support to reduce the possibility o...
