Effectiveness of a Protocol of Respiratory Physiotherapy for Improvement or Maintenance of Respiratory Function, and Incidence of Respiratory Infections in Children With Neuromuscular Diseases, Compared With no Approach by Respiratory Physiotherapy of Respiratory Difficulties: A Randomized Clinical Trial With Two Groups in Parallel With Blinded Evaluator.

The protocol designed was composed of the following exercises: * supine position: inhalation and exhalation with abdominal and thoracic pressures. 5 times * lateral decubitus, with incentive spirometer lung inflation are made on right/left sides. 3 sets on each side * sitting position, with the body leaning slightly forward, head and shoulders bent inwardly directed. It inspire called for 3 times, sent off in air through the mouth, after that the child was coughing * diaphragmatic breathing in a sitting position: after a slow exhalation requested, child should steam a mirror with his mouth slightly open. 3 replications * in a sitting position, with help of an ambu bag, we made inflations. Repeated 3 times * exercises of upper member coupled to respiratory rhythm: shoulder flexion and extension was carried out during the inspiratory phase and the extension and adduction of them during expiration. 3 times
