title: Respiratory function in amyotrophic lateral sclerosis.
abstract: The aim of this study was to examine the vital capacity (FVC) and forced expiratory volume in 1 s (FEV 1) in relation to the site of amyotrophic lateral sclerosis (ALS) onset and the duration of the disease. Respiratory involvement is the principal cause of death in ALS patients. The study was conducted at the Department of Neurology, University School of Medicine in Lublin. The study comprised 18 ALS patients. The average duration of ALS was 12 months. The patients were divided into two groups according to the site of ALS onset and into two groups according to the duration of the disease. FVC was significantly higher in the group of patients with a limb onset than in the group of patients with a bulbar onset of the disease. The study has shown respiratory function disturbances in ALS patients. FVC significantly depends on the site of ALS onset but not on the duration of the disease.
