There are lots of exercises which are used as part of the rehabilitation of foot disorders. The objective of these exercises are usually to strengthen and stretch muscles as well as mobilize the joints. These are one of several tools which foot specialists make use of to deal with a wide range of foot problems. One exercise which has been receiving a lot of recent support is one called the short foot exercise. This exercise is carried out weight bearing and the muscles in the arch of the foot are contracted to shorten the foot. This is touted to strengthen the arch of the foot. If you consider some of the over stated claims online concerning this exercise, it could heal almost everything that will go wrong with the foot, which is obviously incorrect.
The major problem using this exercise is the fanaticism and opinion that so many have that it can fix so many of the conditions that will go wrong with the foot, when there is actually virtually no scientific studies that it's a good choice for anything. Just proclaiming that something is beneficial and expecting that is it does not make it so. That's the logical fallacy of wishful thinking. For that short foot exercise to work it will take time to build up the strength. Lots of foot problems improve after a while, so there is not any way of figuring out if people got better purely because of this natural history or because the exercise did actually work. That doesn't indicate that there is something wrong with the exercise and that it shouldn't be used. It may well be that the exercise is a really helpful and helpful exercise. It just means that the research studies have not been carried out and too much trust really should not be put in any treatment which is lacking in scientific research to underpin its use. Of course keep using the short foot exercise, but use it in the understanding of these problems which are well known about this.
