Abstract: Objective To observe the clinical effect of repetitive peripheral magnetic stimulation (RPMS) on chronic non-specific low back pain (CNLBP) patients. Methods 43 CNLBP patients were assigned to experimental group (n=22) and control group (n=21). Both groups received routine physical therapy. The experimental group accepted RPMS and core stability training (CST), and the control group accepted sham magnetic stimulation and CST in addition. Clinical effect was evaluated by Visual Analogue Scale (VAS) and Oswestry Dysfunction Index (ODI). All the patients were assessed with Modified Clinical Test of Sensory Integration of Balance (mCTSIB) to observe the center of gravity (COG) sway velocity under 4 testing conditions. Results 4 weeks after treatment, the VAS and ODI scores were significantly decreased in both groups (P<0.001); the COG sway velocity under eye open foam support and eye close foam support decreased in the experiment group (P<0.01), however, there was no significant difference in the control group (P>0.05). The scores of VAS and ODI were significantly lower in the experiment group than in the control group after treatment (P<0.001). The COG sway velocity under eye open foam support and eye close foam support were lower in the experiment group than in the control group after treatment (P<0.05). Conclusion Combination of RPMS could improve the clinical symptoms and the posture control ability under complex environment.
