Flexibility and Strength Training in Asthma

"RFST is a physical therapy technique where a certified practitioner extends or flexes a joint with the subject actively resists the motion applied by the practitioner.~During the RFST treatment a subject will lie on a massage table while the practitioner holds the subject's arm or leg and flexes or extends the limb, instructing the patient to resist the flexion or extension produced by the practitioner. The process is repeated a number of times for each muscle while varying joint positions."
