Effect of pulmonary function training instrument combined with resistance abdominal breathing training on respiratory function of patients with cervical spinal cord injury

Objective To observe the effect of pulmonary function training instrument combined with resistance abdominal breathing training on respiratory function recovery of patients with cervical spinal cord injury.Methods Sixty cases of patients with cervical spinal cord injury were randomly divided into the research group（n=30）and the control group（n=30）.The control group adopted sputum drainage nursing , abdominal breathing training and the comprehensive rehabilitation treatment such as limbs functional rehabilitation training , while the research group used pulmonary function training instrument combined with resistance abdominal breathing training in addition for eight weeks .Forced vital capacity （ FVC）, forced expiratory volume in one second（FEV1.0）, maximal voluntary ventilation （ MVV） and the detected rate of pulmonary pathogens were observed and compared.Results The FVC, FEV1.0, MVV was respectively （68.6 ±11.3）%, （75.8 ± 9.3）%and （ 67.4 ±11.6 ）% in the research group after eight weeks , and （ 60.1 ±14.9 ）%, （ 64.3 ± 13.2）%and （57.8 ±13.5）%in the control group, with statistically significant differences （t=2.78,2.52, 2.61, respectively;P〈0.05）.The rate of pulmonary pathogens was 6.67%（2/30） in the research group and 30.00%（9/30） in the control group, and the difference was statistically significant （χ2 =21.23,P〈0.05）. Conclusions Pulmonary function training instrument combined with resistance abdominal breathing training can improve respiratory function recovery and reduce infection rate in patients with cervical spinal cord injury .
