When joint hypermobility is bilateral, one needs to explore systemic issues. Connective tissue disorders may be a contributing factor. The Beighton tests can help assess the magnitude of joint laxity.
Evaluating the SI Joint can be challenging with very small amounts of movement and tests with variable statistical values.
The SI joint is stabilized by a network of ligaments and muscles. The normal sacroiliac joint has been shown to have approximately 2-4 mm of movement. So yes, the SIJ does move!
Anatomy is the Root of Differential Diagnosis As clinicians we frequently hear about how we “create“ pain in our examination or treatment sessions. In the examination process “reproduction” of pain….the pain that brought them to seek care…. is very important. The “reproduction” of their symptoms guides our differential diagnosis. Anatomy is the …
