Long-term lung volume recruitment therapy maintains ventilator weaning in a patient with ALS following tracheostomy.

Long-term lung volume recruitment therapy maintains ventilator weaning in a patient with ALS following tracheostomy.

We report a case of amyotrophic lateral sclerosis (ALS) in a patient in their 50s, presenting with spastic paraparesis and bulbar palsy, treated with lung volume recruitment therapy (LVRT). From early stage in the disease, vital capacity (VC), lung insufflation capacity (LIC) and ALS Functional Rating Scale-Revised scores were regularly measured, and LVRT was continuously performed at home. After 10 years, the patient had complete limb function loss and required nutritional management via gastrostomy and full assistance with daily activities. Despite this, the gap between VC and LIC remained approximately 2000 mL, and the patient was not ventilator-dependent during the day after tracheostomy. Chest CT showed improvement in lower lobe atelectasis due to LVRT. Typically, respiratory physiotherapy is challenging in patients with bulbar palsy or post-tracheostomy, but in this case, LVRT successfully maintained lung mobility. Early LVRT implementation may improve ALS patients’ survival prognosis and warrants further exploration.
