Effects of the Abdominal Draw-in Maneuver and Body Mechanics on Low Back Pain Relief in Nurses: A Quasi-Experimental Study

Purpose: This study evaluated the effectiveness of an intervention combining the abdominal draw-in maneuver (ADIM) and body mechanics for nurses with chronic low back pain (LBP).Methods: A non-equivalent control group pretest-posttest design was used, with data collected from August 30 to December 29, 2023. Participants were nurses experiencing chronic LBP (≥3 months) from a university hospital. Participants were allocated by ward units, with the experimental group (n=30) enrolled first, followed by the control group (n=30). The experimental group received ADIM and body mechanics training, performed ADIM exercises three times weekly for 6 weeks, and received daily text reminders. Exercise adherence and body mechanics usage were monitored weekly. The control group received educational materials upon request after study completion. Outcomes included LBP intensity, LBP disability, lumbar flexibility, and body mechanics performance, analyzed using SPSS version 27.0 through descriptive statistics, the chi-squared test, the Fisher exact tests, the independent t-test, the Mann-Whitney U test, and analysis of covariance. Results: Compared to the control group, the experimental group showed significant reductions in LBP intensity (Z=4.65, p<.001) and LBP disability (F=7.04, p=.010), as well as improvements in lumbar flexibility (t=6.15, p<.001) and body mechanics performance (t=6.91, p<.001). Conclusion: The intervention effectively alleviated LBP, reduced disability due to LBP, and improved lumbar flexibility and body mechanics performance. Thus, integrating ADIM with body mechanics may represent a practical and beneficial approach for reducing pain and enhancing functional outcomes among nurses experiencing chronic LBP in clinical settings.
