The Effect of S.O.T Category II blocking on Low back pain and bilateral pelvic tilting

This study is to determine the effectiveness of supine pelvic blocking, also known as sacro-occipital technique category II blocking, for the treatment of low back pain and bi-lateral pelvic tilting. A total of 50 subjects with sacroiliac joint distortion and instability were recruited in this randomized longitudinal study and were further divided into 2 groups. The sacro-occipital technique category II blocking procedure was performed three times a week until the category II indicator of joint instability had subsided. Participants in control group were subjected to a sham procedure of equal duration and frequency. We assessed pelvic tilting and low back pain before treatment, immediately after treatment, and after 2 weeks of treatment. In the experimental group, there was a significant reduction in low back pain immediately after the treatment when compared to the pre-treatment pain. This reduction continued even after 2 weeks of the treatment. In the control group, the level of pain after 2 weeks of the intervention was lower than the pre-intervention pain. Bi-lateral pelvic tilting also decreased significantly at both time points, which continued to decrease even after 2 weeks of treatment. No change in bi-lateral pelvic tilting was observed in the control group. Consequently, in young subjects with sacroiliac joint distortion and instability, the sacro-occipital technique category II blocking procedure is effective in reducing low back pain and bi-lateral pelvic tilting immediately after treatment, and the effects are sustained for at least 2 weeks. Thus, this procedure could be considered as an alternative treatment in patients with low back pain arising from pelvic subluxation.
