Foot drop

A normal gait pattern is crucial for walking. In correct case the knee extends such that the lower leg swings forward with the foot flexed and raised upward (dorsal flexion) in order to clear the ground. Unfortunately, due to injuries or neurological disorders, the peroneal nerve is damaged or paralysed and the front part of the foot cannot be lifted. This causes the toes to drag along the ground while walking and this condition is called ‘foot drop’. The nerve may be damaged in many ways: after car or sport accident, due to diabetes, stroke or congenital disease such as cerebral palsy.

To avoid dragging the toes, people with foot drop may lift their knee higher than normal or they may swing their leg in a wide arc. This situation may cause serious knee, hip and spinal joints strain.

Foot drop

The treatment of the foot drop is not easy. If the nerve was damaged due to injury or accident, it may be managed with surgery. However, if the foot is dropped due to brain problems (stroke, CP, etc.), the problem with raising the foot may be chronic. Because of this, the most effective and the fastest way of treatment is using professional foot drop brace AM-OSS-21/CCA.
