Effect of Abdominal Drawing-In Maneuver on Peak Expiratory Flow, Forced Expiratory Volume in 1 Second and Pain During Forced Expiratory Pulmonary Function Test in Patients With Chronic Low Back Pain

The aim of this study was to investigate the effect of abdominal drawing- in maneuver (ADIM) of peak exploratory flow (PEF), forced exploratory volume in 1 second (FEV₁), and low back pain during forced expiration. Twenty-two subjects (14 subjects in experimental group, 8 subjects in control group) participated in this study. The stabilizer was used for ADIM training for five consecutive days. Vitalograph PEF/FEV₁ DIARY and visual analogue scale (VAS) were used to determine forced expiratory pulmonary function and low back pain, respectively. Independent t-test and analysis of covariance were used for statistical analysis with a significance level of .05. The findings of this study were as follows: 1) There were no significant differences of ADIM effect of PEF and FEV₁between experimental group and control group. 2) There was a significant pain reduction in experimental group with ADIM. 3) PEF and FEV₁ increased significantly in the fifth day compared with the first day pre-exercise baseline. Therefore, it is concluded that ADIM was effective in improving PEF and FEV₁, and reducing VAS during forced expiration in patients with chronic low back pain.
