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 articleworking 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.
