Which package is right for you usually depends on how serious the problem we’re solving is, as well as on the age of the patient. The more serious the patient is and the older he or she is – the longer the training procedure will be. On average for children below 6 years, 3-month packages are sufficient. For older patients and for more serious cases 6- to 12-month packages are recommended. Adults usually always take between 9-12 months to recover.
