How does an orthosis work? | The most important facts about the lower leg orthosis

How does an orthosis work?

An orthosis is attached to the leg from the outside and is made of solid material. It thus supports the lower leg in its holding function. A built-in joint at the level of the ankle joint or particularly elastic material supports the ankle joint with every step on the one hand, and on the other hand the orthosis enables mobility.

This keeps the gait pattern dynamic. Stiff orthoses can also be used to correct malpositions. These fix the lower leg and foot in a certain position.

This is intended to compensate for the malposition so that affected persons can ideally walk. Many lower leg orthoses are also worn by people with weakness of dorsiflexion of the foot. In this case, the sole of the foot is placed on the orthosis, the sole part is connected to the attachment on the lower leg. Due to the firm sole, the foot cannot tip down when walking, but a fairly normal gait with the orthosis is still possible.

What do I have to consider when wearing an orthosis?

When wearing a lower leg orthosis, the first thing that is important is that the orthosis fits well. If it causes pressure points, for example, or if the leg has too much room for maneuver in the orthosis, injuries to the skin and underlying tissue will occur in the long term. This can result in open wounds or even more severe damage to the muscles, vessels or nerves.

Correct application of the orthosis is also important for it to be able to fulfill its function. There are orthoses that can be worn simply on the naked skin, others are designed to be worn with a stocking underneath. The instructions of doctors, physiotherapists and orthopedic technicians should be followed.

The situations in which the orthosis is to be worn and the daily duration should also be considered. Depending on the indication, this can range from a few hours to a full day. Reasonable support or correction of incorrect posture is only guaranteed if the orthosis is worn for the prescribed time.Furthermore, the lower leg orthoses with joint can be locked in different positions.

Alternatively, only certain movements are allowed in the joint or the joint can be moved freely. As a rule, these specifications change depending on the progress of the therapy. In order to ensure reliable treatment and to prevent both excessive and insufficient strain on the lower leg and foot muscles, the release of the joint must be checked regularly. Finally, attention should also be paid to the shoes in which the orthosis can be worn.
