Over many years, science and medicine have made vast improvements to back braces used to treat a numerous array of injuries. Furthermore there are so many types of braces that're used now to treat all kinds of injuries. In the simplest forms, however, there are two types: rigid (hard) braces and soft braces. Having all kinds of back braces come all kinds of adjustments used to treat them, and these are some of the basic adjustments one can make to it. Starting in the neck and ending in the tailbone as well as having over 30 bones that comprise of it, the term "back brace" can be used to describe any brace that compresses any one of these bones. The first adjustment one can make is to a brace on their necks. Braces for the neck have two types of braces: hard and soft. Adjustments on the soft brace usually are made with velcro to control the tightness of the squeeze on the neck as well as the placement on the neck. The hard brace, however, have many more adjustments that can be made. Because this type of brace are used usually for more serious injuries or conditions, it's more important that this one have more ways to be adjusted. First of all, there are more velcro places that adjust where to put the brace. Secondly, the tightness of all these places affect the overall position and tightness of the brace. A brace that covers from the middle of the back all the way up to the neck, the Minerva brace is one that has even more adjustments than the neck braces. This brace has six locations that hook on to the body. There are two straps that rap around the stomach/waist, two straps that rap around the chest, and two straps that rap around the chin to the back of the neck that hold the chin in place. All of these straps can be adjusted to provide pressure in any one of these areas. Like this brace is the SOMI brace. This brace affects the same areas, but it connects the middle straps by going over the shoulder as opposed to around the chest. The chin strap also connects to the chest to provide more stability. An adjustment as a feature on the SOMI that isn't on the Minerva brace is a bar that the chin sits on. This can be adjusted in length to sit the head in the right location. Braces used for the lower and middle backs alone are more simple, and adjustments rapping around the braces adjust tightness and placement on the back. Although the adjustments might seem simple to use, they're incredibly important to make the brace being used fit correctly on the spine. This can be imperative for proper healing, and it's important that the person wearing the brace work with their doctor in learning how to correctly wear their brace.
