OBJECTIVES: The aim of this study was to investigate the effect of diaphragmatic breathing exercise with biofeedback on respiratory function in incomplete cervical spinal cord injury patients.
DESIGN: Forty spinal cord injury patients (mean age: 32.67 ± 5.08 yrs) were randomly entered into two groups including the control group ( n = 20) and the intervention group ( n = 20). Forced expiratory volume in 1 sec, functional vital capacity, and maximum voluntary ventilation tests were performed to measure pulmonary function and Nijmegen Questionnaire was used to evaluate severity of respiratory dysfunction before, immediately after intervention, and 1 mo after the intervention.
RESULTS: The mean of pulmonary function tests in the intervention group was increased after the intervention ( P < 0.001) and at 1-mo after intervention ( P < 0.001). In addition, the control group indicated no change in these variables. The Nijmegen Questionnaire score also decreased significantly in both groups (control group = P < 0.001, intervention group = P < 0.001). The change of Nijmegen Questionnaire score significantly differed between the groups (F = 4.67, P = 0.03); in addition, significant difference was observed after intervention ( P < 0.001) and 1-mo follow-up ( P < 0.001).
CONCLUSIONS: The application of visual biofeedback during breathing exercise can improve pulmonary function and mechanism may make the Nijmegen Questionnaire improve as a reflection of lowered dyspnea.
