title: Chest and neck mobilization effects on spirometric responses in healthy subjects.
abstract: OBJECTIVE
  In this observational study, we evaluated the effects of chest and neck mobilization on spirometric parameters in healthy subjects.
  
  
  METHODS
  We conducted an observational, quantitative, and experimental study in a sample of 100 healthy subjects. We evaluated spirometric parameters before and after pompage mobilization techniques. Three techniques were used, and each technique was performed 6 times.
  
  
  RESULTS
  Forced vital capacity (3.4 ± 0.1 L vs 3.5 ± 0.1 L), forced expiratory volume at the first second (3.2 ± 0.09 L vs 3.3 ± 0.09 L), and peak expiratory flow (6.4 ± 0.27 L/s vs 6.6 ± 0.25 L/s) were significantly increased after mobilization (P < .0001), whereas Tiffeneau index (94% ± 1% vs 6% ± 0.2%) was decreased (P < .0001).
  
  
  CONCLUSIONS
  Chest and neck mobilization techniques used in this study improved spirometric parameters in a group of young and healthy subjects.
