Respiratory training improves breathing in patients with Parkinson’s disease

This study reviewed the effectiveness of different respiratory training (RT) exercises in patients with Parkinson’s disease (PD). Researchers suggested that RT should be considered to treat these patients.

PD is a chronic disorder that affects over 10 million people worldwide. The disease affects certain brain cells that control body functions. These cells lose their abilities over time, causing symptoms such as muscle weakness.

Muscle weakness in the lungs may be present in the early stages of the disease. However, the rate of progression and the optimal treatment for a lung disorder is unknown. This disorder might lead to impaired coughing, which can be a big risk for patients with difficulty swallowing. This might cause aspiration pneumonia due to the aspiration of saliva, food, or liquid.

RT aims to improve the function of the respiratory muscles through specific exercises. This method is already used in patients with neuromuscular disorders. However, its effectiveness in patients with PD is still unclear. 

This study reviewed 10 other studies. These studies included information about patients with PD and respiratory dysfunction. Different RT techniques were evaluated.

Positive effects were reported for inspiratory and expiratory muscle strength training, air, and breath-staking and sustained maximal inhalation. Postural training, swallowing safety, phonatory system (produces sound with air coming from the throat and lungs) and chest volumes also had positive effects on breathing.

This study concluded that RT exercices showed positive effects in patients with PD and respiratory dysfunction.

Most of the studies included has small patient populations. Large studies are needed.
