Purpose: This study attempts to identify the effects of abdominal strength training using proprioceptive neuromuscular facilitation (PNF) on the balance ability and pain level of patients with chronic lower back pain.
Methods: A total of 30 patients with chronic lower back pain were randomly divided into either experimental group I (n=10), who received abdominal strength training using PNF, experimental group II (n=10), who received abdominal strengthening training, or the control group (n=10), who received conventional physiotherapy. The interventions were applied three times a week for six weeks. We measured Berg's balance scale (BBS) in order to investigate the change in balance ability, while we measured the visible analogue scale (VAS) to determine the severity of pain. We conducted a paired t-test to compare the within-group change before and after the intervention. For the comparison of the between-group difference, we used a one-way ANOVA test. Tukey's test was used as a post hoc test. The statistical significance level was set at α=0.05 for all the variables.
Results: Experimental group I and experimental group II showed a significant within-group change in BBS (p<0.01). A statistically significant between-group difference was observed in terms of the change in BBS (p<0.01). According to the results of the post hoc Tukey test, experimental group I and experimental group II showed a more effective change in BBS than the control group. Experimental group I, experimental group II, and the control group all showed a significant within-group change in the VAS (p<0.01). There was a statistically significant between-group difference in terms of the change in the VAS (p<0.01). According to the results of the post hoc Tukey test, the change in the VAS was more effective in experimental group I than in experimental group II and the control group.
Conclusion: In this study, the application of abdominal strength training using PNF for subjects who complained of chronic lower back pain proved effective in improving their balance ability and reducing pain. We therefore believe that this training method could be applied as a useful program for patients with chronic lower back pain.
