Study findings suggest that combination of the muscle energy technique (MET) combined with gluteus maximum activation exercises for patients with anterior rotated sacroiliac join dysfunction can statistically significantly improve disability at 4 weeks when compared to flexion bias exercises combined with MET. However, this study had several limitations including the lack of blinding for outcome assessors and patients, small sample size of 24 patients, and lack of consistency in at-home exercise programs. Therefore, future larger randomized controlled trials utilizing blinding of outcome assessors and patients in the study and consistent at-home exercise programs are of interest.
Study Summary
Forty-eight patients diagnosed with anteriorly rotated sacroiliac joint dysfunction (SIJD) were randomized to receive the Muscle Energy Technique (MET) technique during their first session combined either with flexion bias exercises (control; n=24) or gluteus maximum activation exercises (n=24) for 4 weeks which occurred twice/week for 20 mins each session. The primary outcome was disability which was the Oswestry Disability Index (ODI) at 4 weeks follow-up. Secondary outcomes of interest included pain which was evaluated using the Visual Analogue Scale (VAS) and pelvic tilt angle using the Palpation Meter (PALM) which were both measured immediately after the intervention and at 4 weeks follow-up. Results of this study demonstrated that a statistical significant improvement in ODI scores at 4 weeks follow-up in the intervention compared to the control (p=0.011); however, all other outcomes were not statistically significantly different between the 2 groups (p>0.05).
