Brief review
*Title:
In healthy subjects, the sitting position can be used to validate the postural
effects induced by wearing a lumbar lordosis brace
*Author: M. Mathias, P.R. Rougier
Aim
of the study
To assess the validity of the sitting
position when testing lumbar braces for the maintenance of lordosis.
Patients
and methods
▶Subject number: 12 young adults (seated on force platform)
▶Experimental
conditions (4 ways)
1. with a brace
2. without a brace
3. with enforced lordosis
4. without enforced lordosis
(For distinguish between the roles played
by lordosis and the brace)
-The trajectories of the centre of pressure (CP) were analyzed
and compared.
(To assess postural orientation and
stabilisation processes)
Results
-Using the lumbar brace led to reduction
in CP displacement (along the mediolateral and anteroposterior axes).
-Lordosis barely affected postural
performance and only an increase in the mean CP velocity was observed.
-An analysis of variance failed to reveal
an interaction between the “lordosis” and “brace” factors.
Conclusion
-A lumbar brace (in the absence or presence
of lordosis) helps subjects to improve their sitting performance.
-Function of brace wear emphasises the
discriminant power of the sitting position: significant differences
-This task should be applied more widely in
the development of more appropriate, validated equipment for lower back pain
sufferers.
