I would obtain their records, talk with their doctors, and have independent physicians examine them to determine their current status. As far as I know, no healer has ever done any of these things. Thus, as far as I am concerned, there is no reason to believe that faith healing has ever cured anyone of an organic disease. But any benefit of this type should be weighed against the fact that people who are prayer heals by replacing bad thoughts with good ones. Christian Science practitioners work by trying to argue the sick thoughts out of the person's mind.
Consultations can take place in person, by telephone, or even by mail.
Individuals may also be able to attain correct beliefs by themselves through prayer or mental concentration. Two weeks of class instruction are required to become a practitioner. During the past few years, believers have claimed that prayer has brought about recovery from anemia, arthritis, blood poisoning, corns, deafness, defective speech, multiple sclerosis, skin rashes, total body paralysis, visual difficulties, and various injuries. Most of these accounts contain little detail, and many of the diagnoses were made without medical consultation. As far as I know, no systematic, medically supervised study of the outcome of Christian Science healing has ever been performed.
