Back pain corsett
Actually.... the correct spelling is “corset.”
What is it? A corset is a brace.
A corset brace is sometimes recommended to limit motion of the spine. It is sometimes used for people with lumbosacral strain or other types of mechanical low back problems such as spondylolisthesis. Surgeons sometimes use a corset in patients after a lumbar fusion. The brace helps limit motion in the back while the fusion sets up by not allowing the patient to bend forward. Bone grows better where there is little motion, and especially in cases where no instrumentation (devices to aid in stability) is used, a back brace can be helpful in obtaining a solid fusion.
People with jobs that involve heavy lifting also sometimes wear corset braces. These braces essentially work by limiting motion and acting as a reminder to use proper body posture when lifting. With the corset brace, one needs to lift with the back straight (not bent forward), using the large leg muscles to do the lifting.
It is important for a patient not to become dependent on the corset. Patients need to be taught specific core muscle strengthening to better utilize their natural “corset” of muscles.
What is the evidence these corsets work? Here are two recent papers...

Evaluation of low back pain and assessment of lumbar corsets with and without back supports
R Million, KH Nilsen, MI Jayson and RD Baker
A method is described for evaluating the progress of patients with back pain. Various symptoms were scored on analogue scales and spinal motion was measured by various techniques. These data were integrated to make subjective and objective indices respectively. Reasonable reproducibility of the measurements was obtained. This technique was used to elucidate the role of the lumbar support in surgical corsets in relief of back pain. Sufferers from back pain were randomly allocated to corsets with and without lumbar supports. There was significant improvement in those with a support compared with those without. On the other hand objective changes measured with the corset removed did not differ between the 2 groups. This study indicates that the spinal support in a lumbosacral corset makes a significant contribution towards the relief of symptoms.

Aims: To assess whether lumbar corsets are being effectively prescribed to control lower back pain in our study group.
Methods: A postal questionnaire was sent to 130 consecutive patients who were prescribed lumbar corset for control of back pain in a 2-year period. 102 (78%) patients responded. The Greenough and Fraser and visual analogue scoring system were used to assess the physical and functional improvement of back pain.
Results: Of the 102 patients responded, 64 were females (62.7%) and 76 (74.5%) patients had worn the lumbar corset for more than 1 year of duration. Ninety (88%) patients normally worn the corset all day or most part of the day. There was an improvement in the total back pain outcome score before versus after wearing the lumbar corset: Greenough and Fraser mean 30.02 up form 20.07 (p<0.0001); and visual analogue mean pain score down to 4.90 form 8.30 (p<0.001). Conclusions: We conclude that lumbar corsets were being effectively prescribed and that there is good compliance and control of back pain in our study group.
