What are the requirements for Manual Osteopathic Therapists? What is the minimum length of time that would be considered acceptable training?

The benchmark for Manual Osteopathic Therapists has already been set by The World Health Organization.
In specific regard to our organization’s acceptance of Manual Osteopathic Therapists we would be looking at the requirements laid out for a WHO Type 2 Osteopathic Therapist, which is 1000 hours of instruction at an approved school.
