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.
