Inclusion Criteria
•All participants will be required to read and sign the participant information and consent form (Appendix B) prior to being admitted into the study. Consent must be received both on paper as well as verbally.
•The participants must be 18 years of age or older in order to negate the necessity for consent from a parent, but not older than 45 years of age as people older than 45 have an increased prevalence of degeneration as seen on radiographs. Walker and Colledge (2013) said that the increased incidence of pathology in older individuals may also influence the results of the study.
•The participants must present with a sacro-iliac joint fixation. The upper sacro-iliac joint mobility test will be used to identify the existence of a fixation (Bergmann and Peterson 2010).
Exclusion Criteria
•Individuals having received a chiropractic manipulation on the lumbar/sacral region four weeks prior to the study. This will prevent the possible effects of previous treatment on the outcome of the results and the readings taken.
•Any patient with SIJ syndrome or pain experienced in the SIJs in the three weeks prior to the study (i.e. the participants must be asymptomatic)(Lamoth et al. 2006).
•Exclude participants taking any drugs which have effects on the skeletal muscles (e.g. statins and spasmed), as this will affect the results of the sEMG (Kruk 2014).
•Individuals presenting with identified clinical contraindications to spinal manipulative therapy, which would require further testing, will be excluded from the study as per the case history and physical examination (Gatterman 1991). Should any of the above mentioned conditions be suspected after carrying out the case history or physical examinations, the participant will be sent for the appropriate investigative procedures and/or referred to the appropriate practitioner for treatment.
•Contraindications to surface electromyography (sEMG) including, but not limited to: open wounds, rashes, psoriasis, skin irriattions, or skin conditions of any kind in the region of electrode placement.
•Patients with a Body Mass Index (BMI) of 30 or higher (due to the potential influence of adipose tissue on the ability to take muscle activity readings) (Kim, Kang and Oh 2014).
•Any lower extremity pain or shoulder pain as any dysfunction in these areas may predispose the POS to imbalances unrelated to the SIJ (due to the attachments of the POS muscles).

- Not specified
- Primary Outcome Measures
Name Time Method Ho: A unilateral SIJ manipulation will result in differences in mean muscle activity and mean force output of the ipsilateral gluteus maximus and contralateral latissimus dorsi when compared to the control group.
- Secondary Outcome Measures
Name Time Method Ha: The intervention group receiving unilateral SIJ manipulation will have no change in mean muscle activity and mean force output of the ipsilateral gluteus maximus and contralateral latissimus dorsi when compared to the control group.
