The aim of this research study was to determine the most effective way of treating sacroiliac
joint dysfunction with associated gluteus medius trigger points, using adjusting of the sacroiliac
joint or needling of the gluteus medius muscle or both.
The participants were recruited randomly and placed in 3 different groups. Participants in
group 1 were treated with an adjustment of the sacroiliac joint, as well as needling of the most
prominent gluteus medius trigger point. Participants in group 2 were adjusted only and
participants in group 3 were needled only. The treatment of the participants took place at the
University of Johannesburg’s chiropractic day clinic.
The objective data was acquired using a Digital Inclinometer to measure the ranges of motion
at the spinal levels of the 5th lumbar vertebra and the first sacral vertebra (L5/ S1). An
Algometer was used to measure the amount of pressure required to evoke pain, within the
most prominent trigger point being treated. The subjective data was acquired using the
Oswestry Pain and Disability Questionnaire, as well as the Numerical Pain Rating Scale.
The results of the trial were of no statistical significance, but clinical improvement in both
objective and subjective data was found. Group 2’s mean value percentage improvement was
the greatest, when looking at range of motion. Group 1’s mean value percentage improvement
was the greatest, with the Algometer and the subjective readings.
The outcome of this study was that overall all three treatment protocols had a positive effect on
the participants. Group 1 and group 2 had a slightly greater overall improvement. Thus it is
suggested that when treating sacroiliac joint dysfunction with associated gluteus medius trigger
points, the doctor can use an adjustment or adjusting with needling, both are effective. It is
important to take the patients preference into account in order to make them feel at ease with
the treatment they are receiving.
