The respiratory muscle rest program has been widely used in cases of chronic pulmonary dysfunction. However, the results were quite controversial in various studies. Recently we treated a 33-year-old man with nemaline myopathy who presented with recurrent respiratory tract infection and respiratory failure. He was treated initially with continuous mechanical ventilation, but a few weeks later, he only needed noninvasive ventilator support at night. During 3 years of follow up, he was advised to use a nocturnal ventilator to rest his respiratory muscles during sleep. Fewer hospitalizations and normalized blood gas values were noted. In addition, he had improved lung volume and respiratory muscle endurance. It is postulated that respiratory muscle rest therapy might be indicated and of benefit for patients who have weak respiratory muscles due to congenital myopathy.
