The peroneal nerve controls the lifting of the tip of the foot.

The peroneal nerve controls the lifting of the tip of the foot. If he fails, for example due to a stroke, a herniated disc or a traumatic brain injury, what is known as dorsiflexion weakness occurs: In order not to stumble, those affected have to lift their entire leg higher when walking because of the drooping foot. Multiple sclerosis or other nerve diseases can also trigger dorsiflexion weakness.

Forms of dorsiflexion weakness

In healthy people, the brain sends Signals to the spinal cord. From there, nerve pathways direct the movement impulses to the nerves in the leg and foot in order to control the foot lifter muscles. In the hollow of the knee, the peroneal nerve is activated to lift the tip of the foot when walking. If the foot is weak, there is a disorder on this path.

Chat log: dorsiflexion weakness

If the foot is weak, the nerve impulses that control the lifting of the foot are absent. The neurologist Prof. David Liebetanz answered questions on the topic in the round-up chat. more

A distinction is made between central and peripheral dorsiflexion weakness:

  • In the central dorsiflexion weakness stroke is often the cause. The motor pathways to the leg are impaired by the damage to the brain or the spinal cord.
  • A peripheral dorsiflexion weakness Often arises as a result of a herniated disc: the disc puts pressure on a nerve in the lumbar spine and damages it.

The aim of the therapies here is to regenerate the damaged nerve.

Therapy of dorsiflexion weakness

physiotherapy is always an important part of the therapy for dorsiflexion weakness. It is particularly important for success after a stroke and other damage to the brain and spinal cord. Most of all that Training the abdominal and foot muscles brings back the strength to walk.

Electrical impulses train the nerves

The risk of injury is great if the foot is weak. Customized, mechanical rails (Orthoses) can give the foot support and support muscles and nerves. They help many people with dorsiflexion weakness to get or stay mobile again.

If those affected cannot cope with the splints, there is a new type cuff. It attaches to the lower leg and sends electrical impulses through the peroneal nerve to the foot lift muscle and other muscles involved in lifting the foot. This gives the muscles the necessary stimuli and the foot now goes up. This Electrostimulator only possible in some cases of central dorsiflexion weakness. Requirement is a intact peroneal nerve.
