Yoga Therapy is individualized and prescriptive in nature, tailored to an individual’s health concerns and needs. In the West, yoga classes are generally an exercise modality. Additionally, a certified yoga therapist must have specific training beyond yoga teacher training. Accredited yoga therapy schools require supervised internships with clients as well as study with nurses, physical therapists, and psychotherapists, among others. New standards additionally require that a yoga teacher has taught at least 100 hours prior to entering a yoga therapy program. It is a good idea to ask a yoga therapist how many hours they have taught yoga.
