Bunion correctors are splints or braces that you are meant to use at night and are professed by those who retail these to correct the bunion (or more properly known as ‘hallux valgus’). If you consider the photos of bunion correctors, it's easy to observe how they could accomplish that. The issue then becomes, do bunion correctors help?
Thinking about the physics as well as bio-mechanics, it is possible to observe how the splint may make an effort to correct the position of the toe throughout the night. The only problem with that thought would be that the following day you have all the strains of weightbearing as well as the footwear continuously pushing the hallux back again the other direction. It's probably likely that those loads simply overcome any improvement which will have taken place overnight, at least hypothetically.
Exactly what does the real evidence say? Just one investigation has shown that bunion correctors do really work. They showed an improvement of a few degrees after a few months of use, which appears a good final result. However, just what the study would not demonstrate (and no additional investigation has investigated) is that if there exists any further improvement if it's used for longer or if the improvement is preserved if utilisation of the bunion corrector is ended. Based upon this it really is hard to give information on if the bunion correctors will work at fixing the angle of the great toe. That doesn't stop a lot of people asking if they actually work in user discussion forums and Q & A groups online.
With that said, that doesn't mean that they don't have there benefits. Even so, that use often must be together with the use of exercise movements along with footwear fitting information. They could very well be primarily effective with helping the range of motion of the joint and that will have a considerable influence on the actual ‘aches and pains’ originating from inside the bunion which may be prevalent in individuals with bunions.
