1. Introduction
This report is the results evaluated from the efficacy of air corset(Disk
Dr.) by measuring changes of the pain, radiographic changes and muscular
strength of the flexor and the extensor at the lumbar vertebrae by making
use of unifrom motion measuring machine after having lumbago patients
wear the air corset(Disk Dr.)
2. The subject of the study
1) The subject of the study
22 patients with acute or chronic lumbago;Age range covers from 19 to
58. Average age:44 8patients are the most in fifties. 9 men and 13 women
by sexes 9 patients with slipped disks, 9 patients with acute lumbago
and 4 patients with chronic lumbago by diseases.

2) Methods of the study
In order to evaluate the efficacy after wearing Disk Dr., Macnab's criteria
was firstly used to examine changes of the pain. Secondly, radiographic
method was used to analyze by photographing side views of lumbar vertebrae
and sacral vertebrae,comparing with those photographed before wearing
Disk Dr.,And thirdly, Cybex 6000 Trunk Extension Flexion(TEF)Unit was
used to measure and analyze muscular strength of the flexor and the extensor
at the lumbar vertebrae.
3. Results of the study
1) Changes of the pain
Macnab'scriteria was used to evaluate the pain. 'Excellent' grade is a
state without pain,
witout any restrictions on movements and that makes it possible to get
back to normal workings. 'Good' grade is a state with pain sometimes,
but possible to get back to nomal workings. 'fair' grade means slight
progress and 'Poor' is just like as it is written, As a result, 85% of
the patients have taken great favourable tums within 3days showing 3 'Excellent'
and 15 'Good' among the total 22patients.

2) Radiographic changes
According to the results from comparing x-rays of side views of lumbar
vertebrae and sacral vertebrae before and after the application of Disk
Dr.in 12-patient cases, the anterior curvature of lumbervertebrae has
been increased and the interval of intervertebral disk at the 4th and
5th segment of lumbar vertebrae has beeb broadened by 3mm average.
3) The evaluation of uniform motion
We have measured the muscular strength of lumbar vertebrae of randomly
selected three persons among 12patients by using Cybex 6000 TEF unit.
According to the results from comparing the graphs measured before and
after the application of Disk Dr. about the total joule at 60 angular
velocity, maximum couple, maximum couple proportion to the weight and
average poser, we decided that Disk Doctor was useful to reinforce the
muscular strength as it showed in the following graphs that the extensor
muscle power remained longer. These exminations were made for two days
in consideration of the muscular fatigue. From this result, we could say
that the radiographic increase of the antenior curvature of lumbar vertebrae
was caused not only by physical body softness but also by strengthening
the muscle power.
4. Conclusion
As a result, 85% of the patients have taken great favourable turns showing
3 'Excellent' and 15 'Good' among the total 22patients. After the application
of Disk Doctor, we could confirm the fact that there was physical body
softness between the segments of the 4th and 5th lumbar vertebrae and
that the motion of extensor lasted longer. These results was obtained
from the various examinations about the efficacy of Disk Doctor presumed
to play a efficient role in treating the acute & chronic lumbago patients.
5. Efficacy and effect of disk Doctor
Disk Doctor is presumed to have effects on the acute and chronic lumbago
caused by the following factors.
.The acute & chronic sprain of lumbar vertebrae .Protruded intevertebral
disk(Slipped disk)
.Divided spinal column .The front & forward position of the spinal column
.The narrowness of vertebral foramen
