Purpose: The study aimed to examine the influence of PNF direct and indirect breathing treatments for patients with cervical spinal cord injuries who had breathing problems. Methods: For each cervical spinal cord patient, force vital capacity (FVC), peak expiratory flow, maximum phonation time (MPT), rib cage width, and VAS were measured pre-intervention and four weeks after post-intervention. The indirect method and the direct method were used for interventions. We treated patients with the indirect method using scapular anterior depression pattern, bilateral extensor pattern with rhythmic initiation, and a combination of isotonic. We treated patients with the direct method, applying pressure on the sternum and using rhythmic initiation (hold relax and stretch reflex) for the rib cage. Training occurred for 50 minutes a day and three days per week for four weeks. Results: FVC, MPT, peak expiratory flow, and rib cage width were increased and decreased at the VAS point for rolling after treatment. Conclusion: Patients with cervical spinal cord injuries who had breathing problems felt uncomfortable when they had conversations on a couch. We found that PNF direct and indirect treatments improved rib cage width and breathing functions of patients with cervical spinal cord injuries.
