Observation of the curative effect of external counter-pulsation therapy on progressive muscular dystrophy

External counter-pulsation therapy was applied to 12 cases of progressive muscular dystrophy with effects of varying degressive markably effective in 3 cases, effective in 6, improved in 2 and no effect in one. In 11 of 12 cases the atrophic muscles became normal, in 3 of 8 cases the gastrocnemius softened and in 9 of 10 cases creatine phosphokinase greatly reduced. Electron microscopy found that the ultramicrostructure of the diseased muscles greatly improved, the structure and morphology of most mitochondria became normal, and glycogenesis disappeared.
