Sacroiliac Joint Involvement in Activation of the Porcine Spinal and Gluteal Musculature

A Randomized Clinical Trial of Manual Versus Mechanical Force Manipulation in the Treatment of Sacroiliac Joint Syndrome

“…50 Such muscular activation assists in providing control of locomotion and body posture and provides stability of the SIJ and lumbar spine. 50 Thus, sensitization of SIJ nociceptive afferents not only contributes to mechanical LBP, but also further plays a role in SIJ biomechanics via reflexogenic activation of the trunk and gluteal muscles.…”

Indeed, other studies have reported alterations in spinal motion in chronic LBP subjects.…”

Non-inflammatory sacroiliac joint disorders

“…Manual therapy may normalise the loads on the joint, capsule and surrounding ligaments. 39 Many of the accepted approaches to the sacroiliac joints are based on models of pelvic mechanics such as those proposed by Fryette, Mackinnon and Mitchell. 40 Techniques used include: Myofascial muscle energy techniques (MET) whilst supine, side-lying or prone.…”

Equine Treatment and Rehabilitation

“…Research suggests this is also the case for joints subjected to shear forces, such as the sacroiliac joint (Eckstein et al 1999;Frank et al 2001). It is thought that the equine musculoligamentous 'sling' and fascial system surrounding the vertebral column and sacroiliac joint (SIJ) may be under proprioceptive control of neural elements within the tissue, as is the case in humans and pigs (Indahl et al 1999;Brolinson et al 2003). Any cause of altered proprioception or altered load transfer through the SIJ or vertebral column may be a reason for development of joint surface changes in horses.…”
