The hamstrings, gluteus maximus, thoracolumbar fascia, contralateral latissimus
dorsi, and triceps create a posterior sling for extension during reciprocal gait, for
trunk stabilization, and for force transmission from the lower to upper body (see
figure 3.9). Vleeming and colleagues (1995) suggested that this posterior dynamic
stabilizing muscular chain provides a stabilizing force for the ipsilateral SI joint.
They noted that the ipsilateral gluteus maximus and the contralateral latissimus
dorsi are connected functionally via the thoracolumbar fascia. Further, the gluteus
maximus and latissimus dorsi are coactivated contralaterally during gait and trunk
rotation (Mooney et al. 2001) as well as during running (Montgomery, Pink, and
Perry 1994).
The posterior chain can be a key indicator of dysfunction in the gluteus maximus and
SI joint. Janda first noticed this in 1964 (Janda 1964), when he found that patients with
an inhibited gluteus maximus (often due to SI dysfunction) activate the contralateral
latissimus dorsi during active hip extension, thus demonstrating the compensation
of this posterior chain.
