ABSTRACT
Objective:To observe the clinical effect of needling gluteus medius muscle trigger point (TrP) plus chiropractic for sacroiliac joint subluxation.Methods:A total of 124 cases conforming to the inclusion criteria of sacroiliac joint subluxation were classified by anterior subluxation and posterior subluxation,and randomized into a TrP group and a conventional group respectively.There were 63 patients with anterior subluxation who were randomized into a TrP group of 32 cases (including 4 dropped out cases) and a conventional group of 31 cases (including 3 dropped out cases);and 61 patients with posterior subluxation who were randomized into a TrP group of 31 cases (including 3 dropped out cases) and a conventional group of 30 cases (including 3 dropped out cases).Patients in the TrP group received the treatment of needling gluteus medius muscle TrP plus chiropractic,while patients in the conventional group received conventional acupuncture treatment plus chiropractic.The treatment was done twice a week for a succession of 8 weeks.Then,the pain visual analog scale (VAS),Oswestry disability index (ODI) and therapeutic efficacy were evaluated.Results:After treatment,the total effective rate of TrP group with anterior subluxation was 96.9％,higher than 77.4％ in the conventional group,the difference showed a statistical significance (P＜0.05);the total effective rate was 93.5％ in the TrP group with posterior subluxation,higher than 73.3％ in the conventional group.After treatment,the VAS and ODI scores in both groups dropped obviously,the differences showed statistical significance (all P＜0.05);the scores of VAS and ODI in the TrP group were obviously lower than those in the conventional group (all P＜0.05).Conclusion:Needling gluteus medius muscle TrP plus chiropractic had a better therapeutic effect than conventional acupuncture plus chiropractic for sacroiliac joint subluxation.
