Basis, indications and risk: Basis, indications and risk
Corsets and lumbar belts
Objetive
To support the lumbar spine by decreasing the strain on the lumbar
muscles.
Theoretical base
One of the functions of back muscles is to contribute to the maintenance
of the normal
spinal curves and the balance of the body in movement. To achieve
this, muscles must contract. A corset allows the muscles to perform
this function with less work. This can improve pain caused by muscle
overload.
However, in cases of progressive scoliosis
in children or adolescents who are still growing, a corset tends
to hold the spine as straight as is possible, which may slow the
progression of the deviation.
Evidence of efficacy
Some of the existing evidence based recommendations
found no studies on the use of corsets or lumbar belts, but experts
who participated in preparing the guidelines judged that they were
not effective in the treatment of acute lower back pain.
Risks and warnings
The constant or prolonged use of corsets or lumbar belts is associated
with muscular atrophy.
Recommendations
The existing evidence based recommendations
do not advise the use of lumbar corsets or support belts for acute
back pain.
Nevertheless, their use may be considered:
- For healthy individuals and those patients who have had back
pain when performing potentially taxing back efforts, such as
weightlifting.
- For acute patients whose pain and muscular contracture limit
their activity significantly, in order to avoid bed rest and to
help them return to their normal daily activities as soon as possible.
- For older patients with acute or exacerbated chronic pain who,
through lack of muscular fitness, may delay returning to normal
daily activities.
- For children or adolescents with progressive scoliosis
who are still growing and for whom exercise is not sufficient
to stop the progression of the curvature.
In adults, in order to minimize the risk of muscle atrophy or
loss of muscular tone, corsets or support belts should be used only
for a few days, avoiding constant use during this period of time.
They should only be worn in instances of major back risk, such as
when the patients must remain standing for prolonged periods or
when they are subjected to vibrations (for example, in tractors
or buses).
In children and adolescents who use a corset due to progressive
scoliosis, it is also necessary to avoid the risk of muscular atrophy.
Therefore, it is important to remove the corset periodically, in
accordance with the physican's prescription for each individual
case. Swimming, especially the backstroke or crawl, should be practiced
at this time, or the recommended exercise program.
