LVVA-SM
This technique has been used at the Palmer Center for
Chiropractic Research in previous studies [75]. In brief,
participants lie face down on a specially designed table
that allows the doctor to apply a controlled motion to
the participant’s lumbopelvic region [75,77]. The doctor
stands to one side and forms a manual contact with the
spinous process of a lumbar vertebra or on the ilium.
This contact resists the distractive force created by flexing
and distracting the table supporting the lower extremities,
which is controlled by the doctor’s other hand.
This procedure allows for a relatively focused distractive
force under the manual vertebral contact and is combined
with flexion, lateral flexion or circumduction

movements generated from moving the table beneath
the lower extremities. Individual motions are determined
based on characteristics of the condition and
therapeutic aim. Distraction combined with specific
movements occurs in 1-3 second intervals, in sets of 5-
20. One to three sets are typically delivered in a given
lumbar or sacroiliac area. Participants are constantly
monitored for tolerance to the amount of motion and
distractive force used during the procedure.
