1.1. What is Functional Electrical Stimulation (FES)?
Neurological diseases often affect, in one way or another, the capacity of motor control or, in severe cases, the complete absence of muscular function; but the nerve conductivity and the excitability of the muscles remain. Functional electrical stimulation uses electrical current to activate the nerves and, as a result, activate the muscle. Fesia Technology enhances the capacity of this technology by applying it to multipad electrodes.
1.2. How long has FES been used in neurorehabilitation?
Since the term was first described in 1967 by Moe and Post in a patent, these devices began to be marketed and used. The first commercial systems were designed for drop foot compensation.
1.3. What are the main benefits of FES?
The main benefits of FES are:
Prevents muscle atrophy
Increases strength and functional improvement
Increases local blood flow
Reinforcement of motor re-learning and neuroplasticity
Maintenance/increase of range of motion
1.4. Is there any evidence of the effectiveness of FES?
There are many scientific articles supporting the use of FES for the rehabilitation of neurological origin deficits. The use of FES for the drop foot compensation is supported by more than 70 scientific publications. The most studied disease is stroke, in which more than 40 studies have been carried out, finding improvements in: walking speed, biomechanical changes in the affected limb, the contralateral limb and the arms, temporal parameters, spasticity, neurophysiological indicators of neurological recovery...
On the other hand, there are more than 25 clinical trials supporting the use of FES for the treatment of the upper limb. It is recommended by the most important scientific societies in the field (evidence-level 1a).
1.5. When is contraindicated the use of FES?
There are some situations where FES is contraindicated:
People with cardiac pacemakers or other electrical or metallic implants, unless recommended by a physician.
People with severe epilepsy or a recent history of frequent seizures.
Tumours or cancerous lesions in the area where electrical stimulation is applied.
2. Our Products
2.1. What are the components of our systems?
The components of our systems are:
Sensor (only in Fesia Walk)
Mobile or Tablet application
2.2. What is a multi-pad electrode?
One of the key features of Fesia Walk and Fesia Walk systems is the multi-pad electrode. The multi-pad electrode combined with an extremely easy-to-use interface allows any user, therapist or patient to try many different electrode sizes and positions without the need of removing the electrode from the skin.
Using a multipad electrode, we produce a more selective activation of desired muscles. This way our products have a better functional performance and muscle fatigue is reduced.
2.3. Do the Fesia systems need any maintenance?
Fesia systems do not require maintenance, but caution in handling to avoid damage from unexpected knocks or falls. Do not attempt to repair the Fesia devices or open the stimulator under any circumstances. In case of breakdown contact a Fesia technician.
If the electrode appears to be dry or loses its adhesion properties, once the protective plastic has been removed, pour about 10 drops of water on it and spread this water over the entire gel with your fingers. Wait 3-4 minutes until the gel has absorbed the water.
You can clean the stimulator and sensor housings using a clean, soft cloth. You can wash the textile garment with soap and water after removing the electrode from the band.
Fesia Walk is a functional electrical stimulation-based gait rehabilitation device, for people who suffer from foot drop as a result of a disease or injury of the central nervous system.
3.2. Who is a candidate for the use of Fesia Walk?
Fesia Walk is a device for people who suffer from foot foot as a result of:
Spinal Cord Injuries
Traumatic Brain Injury
3.3. What does Fesia Walk stimulate?
Fesia Walk stimulates the common peroneal nerve, achieving dorsal flexion of the ankle; and the tibial nerve, achieving plantar flexion of the ankle.
3.4. When should you start to use Fesia Walk?
It has been scientifically proven that the earlier rehabilitation begins, the better results are obtained. Therefore, the use of Fesia Walk should be initiated in acute phases, as soon as the patient is clinically stable.
In addition, people who still do not have balance or strength to walk, or still remain in bed, can star using the device with the “Training” protocol.
3.5. Is it difficult to use Fesia Walk?
No, its placement, configuration and use are simple and fast.
3.6. Does Fesia Walk produce the same effect as an AFO?
No, the following table shows the differences between the effects of Fesia Walk and an AFO:
Increase in walkingspeed.
Increase of motor-evokedpotential and maximumvoluntarycontraction.
4. Fesia Grasp
4.1. What is the Fesia Grasp Device?
Fesia Grasp is a functional electrical stimulation-based hand rehabilitation device, for people who have lost the ability to move the hand and/or fingers as a result of a disease or injury of the central nervous system.
4.2. Who is a candidate for the use of Fesia Grasp?
Fesia Grasp is a device for people who have lost the ability to move their hand and/or fingers as a result of:
Spinal Cord Injuries
Traumatic Brain Injury
4.3. What does Fesia Grasp stimulate?
Fesia Grasp stimulates 14 muscles.
4.4. When should you start to use Fesia Grasp?
It has been scientifically proven that the earlier rehabilitation begins, the better results are obtained. Therefore, the use of Fesia Grasp should be initiated in acute phases, as soon as the patient is clinically stable.
