Cordus y Sacrus
Columna vertebral

The time to notice the results will depend on how severe the diagnosis is, the age of the patient, and other factors. For example, relaxing the lower back is a fairly quick process, however, correct a herniated disc in the lumbar area as a frequent cause of lower back pain or sciatica is always a long process. Regardless of whether the patient applies the therapy in the clinic or at home, the process requires 2 to 6 months or more. In addition, for best results, the patient must apply constantly and multiple relaxation and flexibility therapies to the spine. That is why a method such as Cordus and Sacrus is very useful for those who want to recover their usual activity. This is because it is an effective method that can go beyond the fingers of a specialist, that is easy to apply at home and that saves a lot of money and travel time.

The specialists who manage to have a favorable result on herniated discs, sciatica, scoliosis are very scarce and have a full schedule for the next 2 weeks or have high fees.

The others generally only work on the superficial muscles, providing temporary relief. This is because spasms in the deeper intervertebral muscles cause most back problems.

In addition, to treat chronic problems, relaxation and spinal flexibility therapies must be constant and multiple (from 25 to 30 sessions), and attending in this way with a specialist is complicated.

When the main problem is reached, more seasons with CORDUS are needed. Many patients have claimed that They felt pain, however in a short time (1 or 2 minutes) having gotten a relaxation, they got the relief that they expected.

Watch what our patients say After using CORDUS on a regular basis you will experience relief. CORDUS is not “miracle product” to the back problems, this little uncomfortable moment (1 or 2 minutes) will be transformed into a pain decreased after that a back problem relief. Remember when was the last time that you treated your back, CORDUS is safe and it totally pays off.

NOTE: Do not be afraid of this pain, due to the CORDUS method is totally safe (make sure do not have contraindications), It works with own body pressure, then if an uncomfortable stage is experienced do not worry.

  • If the pain is instantaneous and deep, it means that the superficial muscles and the deep muscles are tense and with spasms, in this case it is recommended that before using CORDUS, the patient tries to relax his back with gentle massages, taking a bath, lying down for 3 to 10 minutes in a bed or chair. After this you can start using CORDUS.

  • CORDUS can be placed on the bed or a mat if too much pain is felt on a firm surface, if the pain is still unbearable, a folded towel can also be placed between the CORDUS device and the patient, thereby overcoming the pain.
  • If the pain is unbearable and is located in the dorsal area, one solution is to place two folded towels, one on the head and one on the hip, to lessen the pressure of the CORDUS device on the spine.
  • Another solution to pain in a specific area of ​​the spine, you can use the CORDUS appliance in an upper or lower area of ​​the spine or skip using the CORDUS appliance in that specific area and use it along the other parts of the spine .

The most important element when using the CORDUS device is relaxation (inhaling and exhaling), so it is necessary that you use CORDUS in the most peaceful place possible, without distractions, if necessary you can put the music that relaxes you the most and reassure.

Think that if all your life you have lived without taking care of your back, the beginning might require a little effort, but the results you will have are worth it.

The relationship between the courses you need and the damage your back has is as follows: For every 2 years that you have not attended your spine, you must take a 10-session course. For example, if you have 10 years without having treated your spine, it will be necessary for you to take 5 courses so that your spine returns to its original state. According to our testimonies, we know that the first 2-3 sessions can be the most difficult stages to adapt to CORDUS, but overcoming this, the exercises can be performed much easier and at ease.

This is normal, after the first sessions of exercise with CORDUS the back may feel sore because the muscles that were previously tense are recovering, it is similar to doing a day of exercise.
