AFO braces improve the stability of your lower leg, namely the ankle and foot. They make walking easier for patients suffering from inherent complications or recovering from an accident. Here are some of the most common reasons people might need AFO braces:
Nerve Injury
Countless neural pathways connect your brain to every other organ and limb. If the nerve in your leg becomes damaged in an accident, you might lose control of your foot. Depending on the scale of the issue, an AFO can be used to help you walk during the recovery period.
Stroke
Strokes can be incredibly dangerous and unpredictable. They occur when a blood vessel in your brain becomes clogged. As a result, parts of your brain won’t receive enough oxygen. If this goes on too long, the brain tissue will start dying. Since strokes can happen virtually anywhere in the brain, it’s difficult to tell what the consequences will be. However, they can affect the lower limbs. In this case, AFOs might be necessary.
Spinal Cord Injury
The spinal cord provides a bridge between the brain and the rest of your body – all nerves sprawl from it. In the worst-case scenario, a damaged spinal cord can lead to paralysis. But sometimes, the effect can be only temporary. If it affects your feet, your doctor can prescribe you an AFO to make walking easier.
Cerebral Palsy
Cerebral palsy is a disorder that affects muscle control and coordination. Though the severity varies from one case to another, affected individuals generally have difficulty walking. An AFO brace might offset these difficulties.
Sciatica
Sciatica refers to the pain in either of the two nerves, which run from the lower back down to the bottom of each leg. In severe cases, affected individuals can experience numbness in one of the legs. Although an AFO won’t treat the underlying cause, it can be used during treatment to relieve some of the symptoms.
Poliomyelitis
Poliomyelitis, or simply Polio, is a dangerous viral disease. Left unchecked, it can lead to paralysis or weakened muscle coordination. If this happens in the area of your ankle, then you might have to rely on an AFO to walk. Fortunately, vaccines are available for this disease.
Diabetes
Unchecked diabetes can cause a series of health complications. As sugar levels rise and blood flow decreases, nerves might not receive all the nutrients they need. It can result in a foot drop if it happens in your leg. Thus, your doctor might recommend using an ankle-foot orthotic to deal with the problem.
Spinal Stenosis
Spinal stenosis occurs when the backbone becomes too narrow to accommodate the spinal cord and other peripheral nerves. It tends to develop with rising age as an accompanying symptom of arthritis. Since the bones begin to squeeze the nerves, it can result in pain and numbness anywhere in the body. Even though surgery might be necessary to fix spinal stenosis, an AFO can make the patient’s life easier in the meantime.
Muscle Dystrophy
Muscle dystrophy is an umbrella term for many diseases that affect muscle function. While each type is slightly different, the general symptoms are the same – over time, an individual’s muscles weaken or lose their function altogether. Muscle dystrophy is mostly a genetic disorder. In milder cases, using an AFO can support the weakened muscle in your foot.
Multiple Sclerosis
Multiple sclerosis is an autoimmune disease. It causes your immune system to attack the protective myelin sheath on top of the nerves. It weakens the strength of the transmitted signal. As a result, patients can experience numbness in their limbs. Braces can improve the balance of the affected leg.
Injuries
The reason to use an AFO doesn’t always have to be so sinister. Accidents happen, whether they are sprains or broken bones. You might have to wear one while your foot recovers from either one of these injuries.
How do they compare to SMOs
When researching various types of braces, you might also come across SMO. Are these any different from AFOs? If so, which one is better?
Well, both types improve lower leg stability. However, they are used in different scenarios.
AFOs are always taller. They can reach up to the knee. Their primary purpose is to stabilize the ankle, foot, and knee. They’re also the perfect answer to drop foot. AFOs prevent falling into abnormal walking patterns and are invaluable in managing many muscle- and nerve-related disorders.
SMO is an acronym for supra malleolar orthoses. They’re much shorter than AFOs, running only up to the ankle. Unlike AFOs, SMOs are made for children. They might be enough to improve foot and ankle stability when the symptoms are too pronounced. These braces are also great for treating pronation. Pronation happens when the feet don’t point straight. Instead, they are pointed too far inwards or outwards. SMOs adjust side-to-side movement accordingly.
What to look for
Although your doctor will tell you which type of AFO is best for you, it will be up to you to work through the details. Since you’ll be wearing your new brace quite a lot, you must feel comfortable wearing it. Here are 5 factors you should consider when choosing your brace:
Size
Your brace should naturally fit you. However, that’s not the type of size we have in mind. Each model varies in length. Certain ones run longer than others. It might impact your mobility. Different orthotics also vary in thickness. While thicker models are more durable, they’re also heavier.
Material
The material also impacts your comfort. Typically, most models are made of plastic. Lightweight yet durable, it’s the perfect brace material. However, some types can be partially made of fabric or metal. While they might be heavier, they’re also more resilient.
Shoe / No Shoe Models
Some models are thin enough to fit into shoes. Others are more robust and act as a shoe themselves.
Replaceable parts
If you have to wear the brace for a long time, you’ll need to consider maintenance too. Quality should be your primary focus. However, braces aren’t immune to the passage of time. Eventually, the many straps and clasps will weaken. For this reason, look for models whose parts are readily available on the market.
Brand
Even though you might be tempted to buy cheap generic models, it might not be the best idea. Reputable brands offer better quality and longevity. Thus, they’re likely cheaper in the long run. Make sure you get your brace from a trustworthy brand such as Ottobock.
CPTs
CPT, or Current Procedural Terminology, is a list of codes that describe medical and surgical procedures and services. Below are three common ones associated with ankle-foot orthosis:
L1902 CPT Code
The L1902 CPT code stands for a pre-fabricated ankle orthosis.
L4397
The L4397 CPT code refers to either static or dynamic ankle foot orthosis.
L4631
The L4631 CPT code refers to a custom-fabricated orthosis with straps.
Conclusion
All told, ankle foot orthosis is a brace designed to improve foot stability. It can aid with symptoms such as drop foot which can accompany many disorders. During their recovery, patients might need to use these braces to walk as effortlessly as possible. Different types exist and each one specializes in a specific condition. They range from r
