It all depends on the health of the patient and how long they have been suffering with their health problem. These are only two possible factors which may determine the number of treatments. Usually, a healthy person will need fewer treatments than a person with many prior health problems or a chronic condition. Most of the time, a short series of treatments (3-5) is necessary to improve the condition of the patient. After that time, treatments may be spaced out more widely and used to stabilise the health problem.
