The underlying disorder must be treated. For example, if a spinal disc herniation in the low back is impinging on the nerve that goes to the leg and causing symptoms of foot drop, then the herniated disc should be treated.
Ankles can be stabilized by lightweight orthoses, and shoes can be fit with springs to prevent foot drop while walking. Regular exercise is usually prescribed.
The latest treatments include stimulation of the peroneal nerve that lifts the foot when you step. Many stroke and multiple sclerosis patients with foot drop have had success with it.
Devices have also been designed to regulate walking. Such as The Soft Foot Drop Brace compared to ordinary drop foot braces are made of hard plastic, molded into shape. The posterior extension runs up the knee, while the leading edge is inserted into the shoe. For this type of footdrop brace to be effective, a sturdy shoe is required. This kind of footdrop brace does not work with loose fitting shoes or most loafers.
