Other Causes of Foot Drop
Foot drop, a condition where a person has difficulty lifting the front part of their foot, can be caused by various muscle or nerve disorders. These disorders lead to progressive muscle weakness, resulting in foot drop over time.
One group of disorders that can contribute to foot drop includes polio, spinal muscular atrophy, and muscular dystrophy. These conditions affect the muscles or nerves, causing them to weaken gradually and leading to the development of foot drop.
Additionally, disorders that impact the brain and spinal cord, such as multiple sclerosis, stroke, and amyotrophic lateral sclerosis (ALS), can also cause foot drop. These conditions affect the central nervous system, leading to muscle weakness and difficulties with foot movement.
In some cases, nerve damage from diabetes can increase the likelihood of developing foot drop. Diabetes can cause nerve damage, known as peripheral neuropathy, which can affect the muscles and nerves in the feet, leading to the development of foot drop.
Risk Factors
Various factors increase the likelihood of developing foot drop, in addition to muscle and nerve disorders. One significant risk factor is the damage or compression of the peroneal nerve, which is located near the skin’s surface on the outer side of the knee. When this nerve is affected, it can lead to foot drop. Individuals who frequently cross their legs or kneel for extended periods, as well as those who have worn a plaster cast below the knee, are at a higher risk of developing foot drop.
