Jobst et al (1986)  studied the effect of acupuncture on chronic obstructive pulmonary disease. They found that 12 patients receiving true acupuncture showed significantly greater benefit than a placebo acupuncture group (n=12) in terms of subjective scores of breathlessness and six–minute walking distance.
Fung et al (1986)  found that real acupuncture was significantly superior to sham acupuncture in protecting against exercise–induced asthma in nineteen children.
