Affected Areas of the Body

What area of the body is affected?

Only one area of the body may be affected by damage to the nerves or the central nervous system (CNS). However, the impairment may also extend to more than one area of the body, for example in case of hemiplegia.


In case of leg musculature paralysis, you often perceive an instability in the leg or knee. Many affected individuals unknowingly overextend their knee as soon as they support weight on it. Overextension is intended to compensate for lost muscle functionality and to secure the knee. However, this compensating movement interferes with a more natural gait pattern and learning how to walk naturally again.



If nerves responsible for dorsiflexion are affected, this makes it difficult for you to pull the tip of the foot towards the body. This dorsiflexor weakness impedes walking: when swinging the leg forward, the foot is too close to the ground so that it gets caught up more easily. Compensating movements such as raising the hip lead to new malpositions.



When one shoulder is paralysed, it hangs lower than the opposite side. Often it rotates inwards and the arm is slightly flexed. The shoulder may even dislocate partially. In this case you feel pain and your mobility is even more limited.



When forearm function is impaired this also affects the hand. The wrist joint and fingers face down. While a sound hand is in a neutral position, this posture is called wrist drop.
