Skin Care: Skin Breakdown and Pressure Ulcer Prevention in Persons with SCI

Untreated pressure sores can lead to widespread infections, limb amputations or worse— loss of life! Even minor problems can get out of hand, limiting your ability to take care of yourself, function at work, or result in lengthy and costly hospital stays. There is no such thing as an insignificant pressure sore.

What is a pressure sore?

A pressure sore (also called pressure ulcer, decubitus ulcer, bedsore, or skin breakdown) is an area of the skin or underlying tissue (muscle, bone) that is damaged due to loss of blood flow to the area. Blood flow to the skin keeps it alive and healthy. If the skin does not get blood, it will die.

Normally, sensation acts as a warning system, signaling you to move or shift your weight to let blood flow return to an area before damage occurs.  Because you may not be able to feel discomfort or pain after a spinal cord injury, you cannot depend on your sensation of pressure to cue you to move or shift weight to relieve pressure. Skin breakdown happens when pressure decreases blood flow to the skin. Up to 80% of individuals with SCI will have a pressure sore during their lifetime, and 30% will have more than one pressure sore.

How do pressure sores happen?

TOO MUCH PRESSURE ON THE SKIN FOR TOO LONG is the most common cause of pressure sores in SCI. Common high-pressure situations are:

 Besides pressure on the skin, other factors increase your risk of forming pressure ulcers too:


 Poor circulation can lead to pressure sores and other skin problems. Some of these problems are increased sensitivity, scrapes or bruises that take longer to heal, and chaffing due to excess moisture or sweating. Without enough blood, oxygen, and nutrients, your skin can't stay healthy.

Sitting or lying in one position for a long period of time decreases blood circulation to the areas supporting your body weight. Pressure sores usually form on parts of the skin close to bone (such as hips and heels) that carry weight when you sit or lie down for a long time.

Swelling or "edema"– often a side effect of paralysis – leaves skin more vulnerable to injury and breakdown. Elevate your legs a few times a day as well as your arms. Support socks/stockings can also help with swelling, however it's best to consult a doctor or nurse regarding foot care and footwear.

Smoking reduces circulation and makes you prone to frequent pressure sores because it dries out the skin. It also increases your risk of respiratory infections such as pneumonia and bronchitis. So, whether you are a heavy or light smoker, the effects on your body are still very harmful!

About 75% of your body's weight is concentrated on your buttocks when you sit upright (MedlinePlus, 2009). Although wheelchair cushions reduce pressure, good skin care and positioning are the most important part of preventing sores.  Areas of your body where you are very likely to develop a pressure sore when you are in your wheelchair are:


Changing positions frequently is key in preventing skin breakdown. Having a schedule for changing positions is one of the best ways to prevent pressure sores. When in your chair, pay attention to your posture; slouching puts more pressure on the lower back and tailbone (sacrum) areas. In a seated position, try to maintain a 90-degree (right) angle between your upper body and your hips. When sitting in your wheelchair, you should do pressure reliefs every 15 to 30 minutes. In bed, you can reduce pressure by placing pillows under and between your legs, and a general recommendation is to change positions every two hours when in bed.

Tips for Changing Positions


Physical Activity

Physical activity has many health benefits and is important for your health and circulation. However, excessive sweating and moisture resulting from exercise make you an easy target for skin breakdown. When exercising, use towels for excess sweat and wear lightweight or loose clothing to help skin breathe. Don't stay in wet clothing after exercising. Pay close attention to your skin's reaction to things like lotions, powders, or fragrances.


You already know that SCI changes your body composition and the way your body uses food. Because of these changes, fewer calories are needed, so you should really try to make those calories count. Try to eat a consistent and balanced diet. Don't skip meals or cut out certain food groups. Poor diet increases your risk of pressure sores and will make it more likely to have recurring pressure sores, more difficulty with healing, and more severe infections. Poor nutrition promotes swelling – which you already know is bad for circulation – and prevents oxygen from getting to cells throughout your body. Being overweight is also risky because it's harder to shift your weight, do pressure reliefs, and move around. Your doctor, nurse, or a dietitian can give you advice about balancing your diet.


Drink Water!!

You need lots of water! If you've got a wound or sore, you can lose more than 4 cups of water each day, just as part of the healing process! While 6-8 cups may be recommended for someone on a catheterization program, others might need more than that. Ask your doctor how much water is right for you.

Also, if you're losing fluids from an open sore – or for any other reason – you'll need to increase your water intake even more. Drinking alcohol is not recommended. If you do choose to, use it in moderation because it often leads to dehydration. It can also prevent your body from effectively using food and vitamins.

Good Eats

A healthy well-balanced diet is important:

General Health

Your physical health affects your skin. If you're sick, every part of your body can be affected. Fevers change your metabolism (i.e. how your body manages energy), alter skin tolerance, and lower your body's infection resistance. Bladder infections don't just affect your bladder; ear infections don't just affect your ears. Remember to check your skin at least twice a day for signs of breakdown because loss of sensation can make it hard to perceive pressure and pain. If you've been sick or hospitalized, muscle atrophy (getting smaller) and weight loss can occur quickly. When this happens, you have less fat and muscle that help cushion your bones and your risk of pressure sores increases.
