Purpose: This study compares and examines the effects of proprioceptive neuromuscular facilitation (PNF) on patients with chronic low back pain through systematic literature review and meta-analysis.
Methods: Domestic literature was searched with combinations of keywords including “proprioceptive neuromuscular facilitation,” “PNF,” “back pain,” and “low back pain” using the Research Information Sharing Service (RISS), Korean Studies Information Service System (KISS), and Korean Medical Database (KMbase). Six studies (n=148) were finally included in the analysis through a selection and exclusion process. The quality of the studies was evaluated using the PEDro scale.
Results: According to the meta-analysis results, the low back pains of the PNF group and the contrast group showed a standardized mean difference (SMD) of 2.21 (95% CI: -3.35, -1.07, p=0.01, I²=83%) after intervention. Thus, the PNF group showed a statistically significant decrease in low back pain compared with the control group. In addition, the SMDs of the Oswestry Disability Index (ODI), lung function, and the Roland and Morris Disability Questionnaire (RMDQ) were -1.34 (95% CI: -1.88, -0.79, p<0.01, I²=35%), 1.14 (95% CI: 0.49, 1.79, p=0.01, I²=0%), and -1.59 (95% CI: -2.56, -0.62, p=0.01, I²=46%), respectively. Thus, the PNF group showed statistically significant differences from the control group.
Conclusion: At present, there is some limit to obtaining definite results about effect sizes because there are relatively few randomized controlled experiments that analyze the effects of PNF exercise in patients with chronic low back pain. Therefore, continuous efforts should be made to conduct randomized clinical trials and long-term efficacy studies in the future.
