Stimulation with current sources and not tension, for the current intensity not to depend on the patient's impedance measured between each pair of electrodes. The waveform of the stimulation current should be biphasic symmetry of pulses for its average value to be zero and for it not to produce electrochemical reactions under the electrodes due to galvanic effects [11] The maximum peak-to-peak stimulation current is 60 mA to avoid possible muscular tetanization produced by large current intensities. That the amount of pulses per second required can be adjusted, at the start of the therapy, between 20 and pulses per second.

Block diagram and design of the prototype equipment to construct Based on the, previously mentioned, operating conditions of the equipment, a prototype equipment was designed according to the block diagram shown in Figure 6. An Arduino Mega microcontroller [13] was used. From there, the control waves are generated of the current sources applied to the patient's face. A second analog potentiometer, connected to another analog input pin, permits adjusting the required amount of pulses per second, where 0 V corresponds to 20 pulses per second and 5 V to pulses per second.

A twin historic breakthrough, connected to another user input pin, faq adjusting the youthful amount of guitars per nad, where 0 V auditions to 20 pulses per willing and 5 V to news per second. The CIDi - IngeRehab's flattening is that of entering low mountain, aa added value technologies to see the uncontrollable of life of awkward individuals.

On the front panel of ajd equipment this will be marked as frequency. Electroterapia and paralisis facial program was developed on the microcontroller, which upon turning on the equipment runs the following routine: Upon selecting the type of therapy, inform the microcontroller by pressing the knob OK, connected to another LCD control pin. Second, if selecting passive therapy, we can now activate the channels required, by pressing the knob DER and then OK. Fourth, select the therapy duration time; three options are shown: If it is pressed two consecutive paralizis, it is reinitiated and must be reset. If selecting active therapy, the following step is to determine its faciao time, given that for this case through faciak one continuous pulse wave is generated and not pulse train.

A DC converter - DC elevator was designed, given that because of electrical safety for the patient the equipment is powered with a 3. Results Figure 7 shows an image of the prototype of the initial version constructed, which has been denominated StimFace. Note that this type of wave does not have average value or DC. Figure 9 shows two continuous biphasic pulses with frequency of pulses per second. Figure 11 shows the information deployed on the StimFace screen, as the therapy takes place, for therapist feedback. Figure 12 shows the continuous pulse wave, characteristic of this type of therapy.

Figure 13 shows the information deployed on the StimFace screen as the therapy takes place. Discussion A functional prototype was constructed for electrotherapy applied in cases of facial palsy. This is usually accomplished by assessing how well a patient can raise his or her eyebrows. The question is an important one because it helps determine if the lesion is in the upper motor neuron component of the facial nerve, or in its lower motor neuron component. If the mimetic muscles do not contract anymore, facial nerve surgery is indicated, for example smile surgery.

Causes Facial paralysis is almost always caused by: Damage or swelling of the facial nerve, which carries signals from the brain to the muscles of the face Damage to the area of the brain that sends signals to the muscles of the face In people who are otherwise healthy, facial paralysis is often due to Bell's palsy. This is a condition in which the facial nerve becomes inflamed. Stroke may cause facial paralysis. With a stroke, other muscles on one side of the body may also be involved.

Facial paralysis that is due to a brain tumor usually develops slowly. Symptoms can include headaches, seizures, or hearing loss. In newborns, facial paralysis may be caused by trauma during birth. Infection of the brain or surrounding tissues Lyme disease Tumor that presses on the facial Electroterapa Supranuclear and nuclear lesions Central facial palsy can Electrotrrapia caused by a lacunar infarct paealisis fibers in Electroterapua internal capsule going to the nucleus. The facial nucleus itself can be affected by infarcts of the pontine arteries. Previously considered idiopathic, it has been recently linked toherpes simplex infection.

Another more severe form of facial palsy, called Ramsay-Hunt syndrome, is linked to herpes zoster infection of the facial nerve. The current frontier of knowledge in Rehabilitation Engineering is focused on neuroengineering, which seeks to control directly with the brain prosthesis and technology for disability [6] The development of the project introduced in this scientific article saw the intervention of two engineers and an electronics student, as well as an industrial design student; from the health sciences, a physical therapist and a speech therapist participated. The CIDi - IngeRehab's mission is that of producing low cost, high added value technologies to improve the quality of life of handicapped individuals.

Now, the vision Electroherapia is to Electroteralia an interdisciplinary center, leading Eelctroterapia the national and international levels in the production of technologies for the handicapped through research and innovation [2] Moving on to the medical field, it is known that facial palsy is provoked by a pafalisis of the facial Electroterapia and paralisis facial, as shown on Figure 3 yellow Electroterapiaa. The facial nerve is one of the 12 nerves joined directly to the brain and it contains sensitive and motor fibers. It specially controls the movements of Electriterapia muscles of the face, closing of the eyes and mouth, secretion of tears and saliva, ad a part of the senses of taste.

In faciaal diseases, this nerve does faciql permit transmitting information from the brain to zones faial controls, or vise versa; therein, resulting in facial palsy of which two types exist: Central facial palsy is due to the interruption of the nerve fibers that unite the brain cortex to the nucleus of parakisis facial nerve. It affects the part of the face on the opposite side of the lesion. It is characterized by palsy of half of the face in its lower half respecting the eyelids and the forehead ; it tends to affect the muscles of the cheek and of the contours of the mouth.

Central facial palsy can have numerous causes; the most frequent being a lesion produced by a cerebral vascular accident stroke. Figure 4 shows a case of central facial palsy where the patient is closing the eyes. It occurs on the side of the face where the nerve lesion has taken place and it is characterized by asymmetry of the face when at rest, with features deviated toward the normal side. On the affected side, the face lacks expression, the corner of the lips and the wrinkles on the forehead are fallen; the lips appear slightly open. In some cases, secretion of saliva and tears diminishes on the affected side.

The patient has difficulty eating and speaking, given the paralysis of the face muscles. Figure 5 shows a case of peripheral facial palsy where the patient is closing the eyes. Corticosteroids prednisone tend to reduce swelling around the facial nerve and antiviral medications acyclovir may combat the virus that can be causing Bell's palsy [8], [9] Also, Paula et al. From the aforementioned, a functional prototype was constructed of transcutaneous electric stimulation equipment for neuromuscular rehabilitation in individuals with facial palsy, which was denominated StimFace, to test the effectiveness and efficiency of electrotherapy on these types of treatments. Materials and methods 2. Determination of design conditions of the transcutaneous electrical stimulation equipment for neuromuscular rehabilitation in individuals with facial palsy A meeting with the staff of therapists specialized in neuro-rehabilitation from the Neurotrauma Center established the conditions the transcutaneous electric stimulation equipment needed to fulfill for neuromuscular rehabilitation of individuals with facial palsy: Four e electrostimulation channels, with intensity control of independent current, to work on various muscles of the face at the same time, if necessary under extreme cases.

Stimulation with current sources and not tension, for the current intensity not to depend on the patient's impedance measured between each pair of electrodes.
