Background:
Brace application has
been reported to be effective in treating idiopathic adolescent scoliosis.
Problem:
The exact working
mechanism of a thoracolumbo spinal orthosis is not completely understood.
In this article, working mechanisms is
a direct compressive force working through the brace upon the body and thereby
correcting the scoliotic deformity, achieving optimal fit of the individual
orthosis.
Purpose:
Measured these direct
forces exerted by the pads in a Boston brace.
Method:
▶Subject
number: 16 patients (with idiopathic adolescent scoliosis)
▶Measurement method: using
the electronic PEDAR measuring device (Novel, Munich, Germany).
(Designed as an
inshoe measuring system. wired to a computer, recording static and dynamic
pressure distribution under the plantar surface of the foot.)
-After positioning
the inserts between the lumbar and thoracic pads and the body, measured the
forces acting upon the body in 8 different postures.
Result:
-Mean corrective force
(through the brace pad): lumbar > thoracic (in all positions)
-Changes in body posture:
significant alterations in the exerted forces.
-Between the
magnitude of the compressive force over the lumbar and thoracic brace-pad and
the degree of correction of the major curve: no significant correlation
-Corrective forces in
new (<6 months) and old (>6 months) brace: no statistically difference.
Conclusion:
-The use of this
pressure measurement device is practicable and of value for studies of the
working mechanism of brace treatment.
-In the future, it
might be of help in achieving optimal fit of the individual orthosis.
