Outcome measures
Primary outcome
Defining the lumbar spines* physiological motion by analyzing sequence of
initiation of motion and sequence of segmental contribution in rotation of each
vertebra L1, L2, L3, L4, L5 and S1 by using flexion and extension
cinematographic recordings in asymptomatic male participants.
Secondary outcome
Exploring the possibility to analyze intervertebral horizontal and vertical
translation of each vertebra L1, L2, L3, L4, L5 and S1 by using flexion and
extension cinematographic recordings in asymptomatic male participants. If mean
intra-class correlation coefficient is higher than 0.60, sequence of initiation
of motion and sequence of segmental contribution of intervertebral horizontal
and vertical translation will be analyzed.
Background summary
This study discribes the physiological motion of the lumbar spine in
asymptomatic male participants. Physiological motion of the lumbar spine is a
subject of interest for medical specialists and paramedics. Unfortunately,
nobody knows exactly what physiological motion means.
There are many studies about maximum range of motions of flexion and extension
in the lumbar spine. Only a few studies describe segmental translation and
rotation of individual segments during flexion and extension. Most of these
studies describe results of pooled data instead of results of individual
participants. They all describe sequence of initiation of movement, not
sequence of maximum contribution of individual segments. Most of these studies
plot cumulative rotation against specific time points or at specific lumbar
ROMs* in graphs, which can lead to missing drastic changes in intervertebral
translation and rotation between successive frames. Some of these studies only
describe flexion not extension or limited flexion up to 40 degrees and limited
extension up to 10 degrees.
Study objective
Defining the lumbar spines* physiological motion by analyzing sequence of
initiation of motion and sequence of maximum contribution in segmental
translation and rotation of each vertebra L1, L2, L3, L4, L5 and S1 by using
flexion and extension cinematographic recordings in asymptomatic male
participants. This information will be plotted with segmental translation of
rotation against total range of motion of the lumbar spine for each individual
participant. By analyzing each individual participant instead of pooled data,
we will determine whether there is a specific motion pattern of individual
segments during flexion and extension.
In the future we hope to compare these physiological kinematics to potential
abnormal kinematics in patients suffering from lumbar spinal pathology, a
common health care problem.
Study design
Fundamental research.
Study burden and risks
Participants will undergo two cinematographic recordings with an interval of
two weeks. The radiation doses is calculated as 0.42 mSv per participant. This
can be categorized in category IIa according to NCS guidelines. This means that
a moderate risk is acceptable if the study provides health advantages for
future patients. We strongly recommend that participants' partner will not get
pregnant during this study or in the following year of the study because of the
radiation dosage. The other recommendation for participants is not to
participate in other studies using radiation dosage in the next following year.
