Background: Mobility of joints of the thoracic spine and rib cage influence chest expansion and lung function both in healthy subjects. To investigate the effects of thoracic spine thrust manipulation on circumference measurements of chest expansion and lung function in healthy subjects. A pre-test and post-test experimental design.
Method: 100 healthy subjects received a single session of thoracic spine thrust manipulation (TSTM). All subjects were evaluated before and after intervention through inch tape of the chest expansion in cm at middle and lower ribcage and spirometry measures of FVC (Force Vital Capacity), FEV1 (Force Expiratory Volume per 1 sec) and FEV1/FVC%.
Result: Thoracic Spine Thrust Manipulation (TSTM) produced significant changes on measures of chest expansion at 4th intercostals space (-1.190 ± 0.720 cm), Xiphoid process (-1.300 ± 1.586 cm) and also on FVC (-0.27880 ± 0.280L), FEV1 (-0.24450 ± 0.330L), FEV1/FVC% (-1.97910 ± 3.196L).
Conclusion: TSTM had significant influence on chest expansion and improved of the spirometric measures of lung function. To be performed in patients with cardiopulmonary disorders on large sample size with long-term follow-up studies and population-based clinical trials.
