[Purpose] This study evaluated the effects of air stacking on pulmonary function and peak cough flow in patients with cervical spinal cord injury. [Subjects] Twenty-six patients were included in the study and were randomized into experimental (n = 14) and control (n = 12) groups. [Methods] Both groups performed therapeutic exercises: the control group performed incentive spirometry, while the experimental group performed 20 repetitions of air stacking exercise twice a day. The training for both groups continued for 5 days a week for 6 weeks. [Results] Forced vital capacity and peak cough flow increased significantly in the experimental group compared to the controls. All within-group variables in the experimental group differed significantly at 6 weeks compared to baseline, while in the control group only Forced vital capacity differed significantly at 6 weeks compared to baseline. [Conclusion] Air stacking exercise significantly improved pulmonary function and peak cough flow in patients with a cervical spinal cord injury.

“…The application of an inspiratory load is a method used for inspiratory muscle training (IMT) (Hostettler et al, 2011); it helps to increase endurance and respiratory muscle strength in order to improve lung function (Sasaki, 2007), functional capacity (Shakouri et al, 2015), and efficacy in bronchial airway clearance (Oliveira et al, 2009). Three IMT techniques reported in literature are more commonly used: voluntary isocapnic hyperpnea, flow resistive loading, and pressure threshold loading (McConnell and Romer, 2004).…”

Objectives The aim of this study was to evaluate the acute effects of different inspiratory loads and different interfaces on the breathing pattern and activity of the respiratory muscles. Methods Twenty healthy adults were recruited and assigned to two groups (20 and 40% of the Maximal Inspiratory Pressure) by way of randomized crossover allocation. Subjects were evaluated during quiet breathing, breathing against inspiratory load, and recovery. The measurements were repeated using two different interfaces (nasal and oral). Chest wall volumes and respiratory muscle activity were assessed with optoelectronic plethysmography and surface electromyography, respectively. Results During the application of inspiratory load, significant changes were observed in the respiratory rate ( p < 0.04), inspiratory time ( p < 0.02), minute ventilation ( p < 0.04), tidal volume ( p < 0.01), end-inspiratory volume ( p < 0.04), end-expiratory volume ( p < 0.03), and in the activity of the scalene, sternocleiomastoid, and parasternal portion of the intercostal muscles (RMS values, p < 0.01) when compared to quiet breathing, regardless of the load level or the interface applied. Inspiratory load application yielded significant differences between using nasal and oral interfaces with an increase in the tidal volume ( p < 0.01), end-inspiratory volume ( p < 0.01), and electrical activity of the scalene and sternocleiomastoid muscles ( p < 0.01) seen with using the nasal interface. Conclusion The addition of an inspiratory load has a significant effect on the breathing pattern and respiratory muscle electrical activity, and the effects are greater when the nasal interface is applied.

“…However, these group differences were not significant. Previous studies demonstrated that smaller lung resection areas are associated with greater differences in respiratory muscle strength before and after surgery 8 , 9 ) . We speculate that respiratory muscle strength did not differ significantly among our groups because all subjects had undergone video-assisted thoracoscopic surgery, which requires a minimal incision in the respiratory muscles interacting with the chest wall.…”

[Purpose] This study evaluated the effects of caregiver education on pulmonary rehabilitation of patients who have undergone lung resection for cancer. [Subjects] Patients were divided into experimental (n = 22) and control (n = 19) groups. [Methods] The caregivers of the experimental group patients received education on pulmonary rehabilitation, while the control group patients received general management advice for 4 weeks. [Results] Pulmonary muscle strength (maximum inspiratory pressure and maximum expiratory pressure) was increased significantly in the experimental group compared to the control group. Modified Borg scale scores were decreased significantly in the experimental vs. control group. [Conclusion] Providing caregivers with education pertaining to pulmonary rehabilitation was associated with improved pulmonary function in lung cancer patients following lung resection.
