ABSTRACT: |
RATIONALE AND OBJECTIVES: We demonstrated quantitatively, using ultrasound imaging, the
passive range of motion of the normal sacroiliac (SI) joint. METHODS: Ultrasound images of
the SI joints of 22 adults at rest and during a manual medicine maneuver designed to
induce a passive range of motion in the SI joint were obtained. Differences between the
baseline alignment of the SI joint and alignment during induced passive motion were
observed and measured by six radiologists. RESULTS: Significant movement (> 2 mm) of at
least one SI joint was demonstrated in 82% of the subjects using ultrasound recordings.
Interobserver (r = .49 - .81) and intraobserver (r = .87) correlations were high.
CONCLUSION: The results suggest that the range of passive SI joint motion is more than 2
mm, and may be up to 10 mm in some normal subjects, and that ultrasound imaging could be a
useful method for assessing passive SI movement. |
