Imagine the helplessness you feel when you lose control of your arm or leg after an accident or a stroke . This happens when the messages from the brain don't reach your arm or leg properly. So today we're talking about a special treatment that helps reactivate these inactive and weakened muscles and move them. This is called FES, which stands for Functional Electrical Stimulation.
Simply put, what is FES?
Simply put, FES is a treatment that uses a small electrical current to stimulate your nerves and muscles . Just like we would talk to someone who is sleeping and wake them up, this electrical current "awakens" the dormant nerves and tells the muscles to "contract." This causes the muscles to contract and start moving.
This is like giving external help to muscles that cannot exercise on their own. This treatment method is very beneficial for people who have weakened muscles due to conditions such as stroke and spinal cord injury.
What are the main benefits of FES therapy?
Depending on the purpose of FES therapy, its benefits vary. Through this therapy, a person can greatly improve their ability to perform daily activities .
| Usefulness | Simple explanation |
|---|---|
| Restoring muscle movement | It helps to repeat things like moving your limbs, walking, and holding something in your hand. |
| Urinary and fecal control | It stimulates the muscles involved in bladder and bowel function, helping to regain control of them. |
| Making breathing easier | It stimulates the diaphragm, which helps with breathing, and can sometimes help get rid of a ventilator . |
| Preventing Bed Sores (Pressure Sores) | It stimulates the muscles in the buttocks area of patients who stay in the same position for a long time, preventing the formation of bedsores. |
| Pain reduction | This method also helps reduce pain by blocking pain signals from reaching the brain. |
Who is this treatment suitable for and who is it not suitable for?
FES therapy is not suitable for everyone. Your doctor and physiotherapist will decide whether this treatment is right for you. First, a short test that lasts about an hour will be done to see if your muscles respond to this electrical stimulation. If you respond well to it, this treatment is right for you.
| Who is suitable for FES treatment? | Who is not suitable for FES treatment? |
|---|---|
| People with muscle weakness | People with electronic devices (e.g. pacemakers) implanted in the body |
| People with conditions such as paralysis | People with cancer |
| People who have suffered from conditions such as stroke and spinal cord injuries | People with epilepsy |
| People with Cerebral Palsy | Pregnant women |
| People with weakness after brain or spinal cord surgery | People with severe osteoporosis |
Your doctor will make the best decision about this after examining you. Therefore, if you have any of these conditions, it is very important to talk to him openly about it.
How does FES treatment feel? Is there pain?
The biggest question many people have is whether it hurts. In fact, FES treatment is not painful . However, it may feel a little uncomfortable and strange.
Imagine, you may feel a tingling sensation, like when your leg is tingled, or a feeling like ants are walking around. If you increase the intensity a little, you may even feel a slight burning sensation. However, this intensity can be adjusted to a level that is not uncomfortable and can be tolerated. Your doctor or therapist will make sure that this is maintained at a comfortable level for you throughout the treatment.
What are the possible risks and complications?
As with any treatment method, FES treatment may carry some minor risks.
- Redness or irritation of the skin where the electrodes were placed: This is usually temporary.
- Discomfort during treatment: Some people may take some time to get used to this electrical stimulation.
- Muscle fatigue: Muscles can feel tired if they are overstimulated.
- Problems with implants: Very rarely, infections of the implanted devices, wire breakage, etc. can occur.
Important: If you have an implanted FES system, you may not be able to have an MRI scan because these devices contain metal parts. It is essential to inform your doctor about your FES device before having this procedure.
What is the difference between TENS and FES?
Many people confuse TENS and FES treatments. Although both use electrical stimulation, their purposes are completely different.
| Characteristic | TENS (Transcutaneous Electrical Nerve Stimulation) | FES (Functional Electrical Stimulation) |
|---|---|---|
| Target nerves | Sensory Nerves | Motor Nerves |
| Main objective | Pain reduction. | Muscle movement. |
| Muscle contraction | Muscles do not contract. | Muscles contract . |
When to call your doctor
If you experience any discomfort during FES therapy, tell your doctor or therapist immediately. Also, if you notice any pain, severe redness, or soreness where the electrodes were placed, let them know. You may be able to resolve the problem by changing the type of electrode or the amount of stimulation.
Take-Home Message
- FES is a very useful treatment method that helps strengthen and move muscles that have been disabled due to an injury. While it does not completely cure conditions such as paralysis, it can greatly improve the quality of life .
- This treatment is not painful, but it may take some time for you to get used to the sensation.
- FES therapy is not suitable for everyone. Only your doctor can determine if it is right for you.
- If you experience any discomfort or skin problems during treatment, never hesitate to inform your medical team.
