This article is intended as a starting point. I am not a doctor and TLA is not a medical blog. This post is not intended in any way to replace a trained healthcare professional. Talk to your doctor if you think medical corsetry may be right for you.
The relentless stream of anti-corset propaganda, which often takes place in the form of concern trolling, can be especially frustrating to me because over the years I have seen far more cases of corsets providing medical support than causing any damage to the body. Even one of the comments on one of my last articles was from a woman who wears her corset for largely medical reasons, spanning a variety of issues from scoliosis to asthma (!!). (Scroll to Deanna's comment at the bottom.) But the myths persist, based on improbable risks that have more to do with ill-fitting corsetry and the miniscule percentage of extreme corset enthusiasts than 99% of modern and historic corset wearers. The following is a short list of just some of the medical benefits of corsetry which I've witnessed in my years making and fitting corsets.
If you are intrigued by the prospect of medical corsetry, please consult with your doctor and don't forget that you get what you pay for. Medical corsets in particular should be purchased from an expert corsetiere and custom fitting is often integral to their functionality. The angle and placement of seamlines is vital to a perfect fit, and the level of boning (both number of bones, flat vs spiral, and rigidity of the boning) should be tailored to your needs and preferences.
Back Support
It's especially ironic that one of the most pervasive myths about corsets is that they are inherently "bad for your back," or, "horrible for your skeleton." Often, when I lace someone in for the first time (especially men), they let out a sigh of relief and comment on the amazing back support. I've even repeatedly heard that the corsets are far more comfortable and effective than a typical back support belt, not to mention significantly more attractive! The associated risk is that IF you wear a corset ALL the time (save for bathing) and do not do any core exercises, you may experience a slight weakening in your abdominal muscles. In all but the most extremist corset wearers, it's unlikely that this weakening would be pronounced enough to affect day to day activities.
Posture Improvement
Putting on a corset will immediately improve posture through the lower back (though, unless the corset has straps, shoulders are usually still free to slump). Consistently wearing a corset will help the body retain good posture even when uncorseted, an affect I've definitely appreciated since I started waist training at the beginning of the year. The taller the corset, the more of your spine it can support in an upright position. Maintaining upright posture can reduce aches and digestive problems (more info available from Lucy, naturally)... Proper posture can not only improve the hang of your clothing, it can also improve confidence, both real and perceived, as Sarah Chrisman discovered for herself. Make sure the fit of your corset suits the natural curvature of your spine; if you suffer from lordosis it may take some experimenting with boning types and bending to get the right shape. As ever, be communicative and clear when consulting with your corsetiere.
Scoliosis
Many of the clients I've worked with at Dark Garden are seeking corsetry to replace the back brace that gave them much-needed support in earlier years. Corsets can even be made that can aid in correcting scoliosis over time. (Lucy has a short article on this subject.) A master corsetiere should be commissioned for a scoliosis support corset, as the degree of asymmetry can be very pronounced. Those with scoliosis often like their corsets to be particularly tight throughout, with less ease through the ribs and hips.
Hypermobile Joints
Some people have naturally loose joints, and some - notably circus performers such as contortionists - loosen and stretch their joints over time. A corset can serve as an exo-skeleton, holding the body together, provide (once again) support, and bracing it from being jarred. Dark Garden even made a pregnancy corset for a long-time custom client with hypermobile joints, who was concerned about the further impact the pregnancy could have on her joint issues. As with scoliosis, if hypermobility is a concern, you may find yourself wanting a tighter and more rigid bind to lock in your rib cage and hip joints. A longline, high back corset would be my recommendation.
Osteoporosis
This is something I don't see as often, but I worked a few times with a lovely client who turned to corsetry after being diagnosed with osteoporosis. (Joyce, we miss you, come back and visit us!) It's been a while since I worked with her, but basically I believe the corset served to stabilize and support her spine, and assisted with pain management. After just a few weeks in a ready-to-wear, she noticed improvement and upgraded to a fully custom piece with a high back and straps.
Diastasis Recti
Though diastasis recti is commonly associated with postpartum women, it can happen to men as well, as was the case with the gent I helped at this past weekend's Dickens Fair workshops. He was under medical advisement to wear a binder to help rejoin his separated abdominal muscles, but found that it had too much give; the stretch wasn't providing enough resistance. Nine months ago he started wearing a corset day and night and he's now noticed improvement in his condition, lost weight (also medically advised), and dropped two corset sizes from a 39 to 35. For women wearing corsets after pregnancy, the corset will help ease down the expanded rib cage as well as holding together the abdominal muscles.
Compression Therapy
Compression therapy can be used to treat anxiety. Corset fans have long described the feeling of being laced in (to a well-made, well-fitted corset, of course) as being like that of an all-day hug. As it turns out, you also get some of the therapeutic benefits of being hugged by your corset as well! Compression therapy can help manage anxiety levels throughout the day. The primary challenge is that those with anxiety issues may also have difficulty with feelings of confinement, so knowing how to get out of your corset quickly in a pinch is important. Though there has yet to be a particular study on the effects of corsets and autism, deep pressure therapy is sometimes used to calm and help focus individuals with autism-spectrum disorders.
Menstrual Cramps
Your mileage may vary, of course - personally I can't stand being corseted at the beginning of my cycle. However, if you are the sort who likes to curl into the fetal position to ease your cramps, a snug corset can exert the same sort of pressure on your lower abdomen and thus enable you to go about your day, far more functional than you would have been otherwise. I had a coworker who tended to tightlace during her period for this very reason.
So the next time someone tries to tell you corsets are bad for you, just try spouting off a few of these wonderful medical advantages to wearing a corset! Do you wear a corset for your health? What style of corset have you found best for your particular health needs?
