Optimization of pulmonary function, functional capacity, and quality of life in adolescents with thoracic burns after a 2-month arm cycling exercise programme: A randomized controlled study

BACKGROUND

Burns to the thorax are at high risk for long-term pulmonary complications due to chest muscle contractures and chronic inflammation in both adolescents and young adults. Few studies have investigated the effects of arm cycling exercise in those individuals. For that reason, this study examined pulmonary function, functional capacity, and quality of life (QOL) in adolescents with thoracic burns subsequent to 2-month arm cycling exercise programme.

METHODS

A single-blinded, two-month randomized prospective controlled study was carried out between July 2019 and March 2020 on thirty adolescents with chest burns aged 11-17 years. They were randomized into two equal groups (n = 15), traditional physiotherapy programme (control group), and arm cycling exercise plus traditonal physiotherapy (arm cycling exercise group) for 2 consecutive months. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), six-minute walk test (6MWT), and Pediatric Quality of Life Inventory (PedsQL) were measured in both groups at baseline and after 2-month after intervention.

RESULTS

No statistical significance was detected at baseline between control and arm cycling exercise groups (FVC, p = 0.903, FEV1, p = 0.835, 6MWT, p = 0.817, and PedsQL, p = 0.612). 2 months after intervention showed statistical improvements in the arm cycling exercise group in all measures (FVC, p = 0.001, FEV1, p < 0.0001, 6MWT, p = 0.001, and PedsQL, p = 0.001) however, the control group showed statistical improvements in FVC, p = 0.044 and FEV1, p = 0.024 with non-statistically significant changes in 6MWT, p = 0.145 and PedsQL, p = 0.067. The arm cycling exercise group showed greater improvements than control group in the outcome measures (FVC, p = 0.034, FEV1, p < 0.017, 6MWT, p = 0.037, and PedsQL, p = 0.021).

CONCLUSIONS

This prospective study clearly demonstrated positive and beneficial influences of two-month arm cycling exercise in the optimization of pulmonary functions, functional performance, and QOL in adolescents suffering from chest burns and thereby eliminating post-burn complications.

Ethical and equity issues in lung transplantation and lung volume reduction surgery

New medical and scientific disciplines are often developed in haste with rampant enthusiasm and scant regard for the balance between action and thoughtful deliberation. Driven by the desire to prolong life and provide a better quality of life for desperately sick individuals, the twin modalities of lung transplantation and lung volume reduction therapy have only just reached their majority. Both are invested with the capacity to help and to harm so it is right to consider carefully their ethical and equitable distribution. Much has been learned in the last 20 years to assist in these deliberations. First, how can we ensure equity of access to transplant services and equality of outcomes? How do we balance resource allocation of a precious and scarce resource with individual recipient needs? Does the concept of distributive justice prevail in our daily work in this field? How do we honour the donor and their family? How do we as practitioners avoid ethical dilemmas related to personal bias and justifiable reward for services rendered? Finally, how do we learn to incorporate ethical forethought and planning guided by experts in the area into everyday behaviour?
