Background
Yoga
as alternative form of therapy has shown positive impact on pulmonary functions, exercise capacity, behavioral changes, and inflammation in non-trauma patients. However, the efficacy of
Yoga
has not been studied in chest trauma patients.
Methods
This randomized controlled trial was conducted at level-1 Trauma Centre. Isolated chest injury patients were randomized into either standard physiotherapy or
Yogatherapy
groups. Patients in physiotherapy group received conventional chest physiotherapy and
Yogatherapy
group received a set of
Yogic
exercises in addition to conventional chest physiotherapy. Primary outcome measure was changes in pulmonary function tests (PFT) at 4 weeks of discharge. Secondary outcomes were changes in quality of life (QoL), respiratory muscle strength and endurance, chest wall mobility, and levels of cytokines at 4 weeks. Data were analyzed using STATA v14.0.
Results
A total of 89 eligible patients were randomized to physiotherapy (
n
= 46) and
Yoga
therapy (
n
= 43) groups. Demographic characteristics were comparable in both the groups. There were statistically significant improvements in PFT in the
Yogatherapy
group compared with physiotherapy with an increase in Forced vital capacity (
p
= 0.02) and Forced expiratory volume (
p
= 0.01) at 4 weeks. In addition, there were significant improvement in physical component of QoL, respiratory muscle endurance (
p
= 0.003) and axillary cirtometry (
p
= 0.009) in the
Yogatherapy
group. However, no statistically significant difference in the trends of cytokine markers seen between the groups.
Conclusion
Yoga
was found to be effective in improving pulmonary functions and QoL in patients with chest trauma. (Trial registered at ctri.nic.in/clinicaltrials/login.php, numberREF/2016/05/011,287).
