Research summary
Surgical lung resection (removal of all or part of the lung) is the most effective treatment for curing localized lung cancer. Surgery affects the function of the respiratory muscles limiting deep breathing and effective coughing to clear mucus. This can increase the risk of infection and hinder lung expansion. Inspiratory muscle training (IMT) involves breathing in against a resistance to strengthen the respiratory muscles, perhaps reducing the likelihood of developing postoperative complications. The effectiveness of IMT in surgical populations is unclear, but to date mostly endurance-based training protocols have been applied (low resistance, long duration). To best improve strength, training ought to be performed at high resistance loads for short durations and therefore high intensity IMT (HI-IMT) may be a more appropriate training strategy.
Participants will be issued an inspiratory muscle training device (Powerbreathe Medic) at their pre-operative clinic. Once shown use of the Powerbreathe medic device Patients will be asked to complete 36 breaths (6 sets of 6 breaths) twice daily with rest intervals becoming progressively shorter between each set until returning for their operation. Post-operatively the use of the Powerbreathe medic will be recommenced after they have completed their inpatient Physiotherapy discharge goals until they return to their post-operative clinic review (4-6 weeks post-operatively).
Therefore, the purpose of this study is to explore if HI-IMT is acceptable to individuals referred for a lung resection and if it is effective at improving: inspiratory muscle strength, infection rates, length of hospital stay, health-related quality of life and walking speed. We hope that the information collected during this study will help to inform and improve our services in enhancing patients’ surgical recovery and experience.REC name
