Subcutis Functions as thermal insulator and shock absorber
www.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/ Also contains: Fat Blood vessels Sensory receptors Hair follicles Sweat and sebaceous glands 2 Decubitus Ulcers (Pressure Sores) Breakdown due to external force applied over
bony prominence for a period of time Due to compression, shear of blood vessels, or friction Common with individuals with sensory deficit (spinal cord injury, hemiplegia) Typical sites: sacrum, ischium, trochanter, heel, scapula 5 stages:
1.Reactive hyperemia Redness that goes away 2.Non-blanching hyperemia Skin stays red; sore on dermis only 3.Sore extends down to subcutaneous tissue 4.Sore extends through fat layer and muscle becomes swollen 5.Sore extends below fascia into muscle or bone 3 Decubitus Ulcers (Pressure Sores) Pressure sores typically occur with: Thin, bony body type e.g. from muscle atrophy Lack of sensation common in SCI Lack of mobility necessary to shift weight overweight, paralysis Poor microcirculation common in SCI and diabetics Increased temperature and humidity at interface Poor health or hygiene Poor nutrition Age
4 Cause of mortality for 4% of people with spinal cord
injury Seating and Positioning Different needs for different people. Examples: Individuals with abnormal tone that affects his/ her ability to assume and maintain symmetric erect sitting posture Individual with neurological or joint condition that results in postural deformity and contractures Individual at risk of or presenting pressure sore due to impaired/absent sensation or inability to independently change position Goals of rehab professional Reduce deforming effects of abnormal tone Correct or delay progression of deformities Accommodate fixed orthopedic deformities Improve functions such as balance, head control, mobility, activities of daily living Reduce the risk of pressure sores 5 Seating Components Correct seating and posture relies on: Pelvic and thigh support Trunk support Shoulder support Head/neck support Upper/lower extremity support 6 ...
