What is a March Sign?
A March Sign is a neurological sign that indicates damage to the corticospinal tracts. It is characterized by an involuntary flexion of the toes when the foot is dorsiflexed. The March sign is named after the neurologist who first described it, Dr. Charles March.
The March sign is important because it can help to diagnose damage to the corticospinal tracts. This damage can be caused by a variety of conditions, including stroke, multiple sclerosis, and spinal cord injury. The March sign is also a useful prognostic indicator. Patients with a positive March sign are more likely to have a poor prognosis than those with a negative March sign.
The March sign is a simple and easy-to-perform test that can provide valuable information about the integrity of the corticospinal tracts. It is an important tool for neurologists and other healthcare providers who care for patients with neurological conditions.

Definition
The March sign is a neurological sign that indicates damage to the corticospinal tracts. The corticospinal tracts are a group of nerve fibers that connect the brain to the spinal cord. These tracts are responsible for controlling voluntary movement. Damage to the corticospinal tracts can cause a variety of symptoms, including weakness, spasticity, and difficulty with coordination.
The March sign is a simple and easy-to-perform test that can help to diagnose damage to the corticospinal tracts. The test is performed by dorsiflexing the foot (i.e., pulling the toes up towards the shin). If the March sign is positive, the toes will involuntarily flex (i.e., curl downwards).
The March sign is an important diagnostic tool for neurologists and other healthcare providers. A positive March sign can help to confirm a diagnosis of damage to the corticospinal tracts. This information can then be used to guide treatment decisions.
For example, a patient with a positive March sign may be referred to physical therapy to help improve their mobility. In some cases, surgery may be necessary to repair the damaged corticospinal tracts.
Understanding the connection between the March sign and damage to the corticospinal tracts is essential for healthcare providers who care for patients with neurological conditions. This understanding can help to ensure that patients receive the correct diagnosis and treatment.
Causes
The March sign is a neurological sign that indicates damage to the corticospinal tracts. The corticospinal tracts are a group of nerve fibers that connect the brain to the spinal cord. These tracts are responsible for controlling voluntary movement. Damage to the corticospinal tracts can cause a variety of symptoms, including weakness, spasticity, and difficulty with coordination.
There are a number of different conditions that can cause damage to the corticospinal tracts, including stroke, multiple sclerosis, and spinal cord injury.
- Stroke: A stroke occurs when there is a blockage of blood flow to the brain. This blockage can damage the corticospinal tracts, leading to a positive March sign.
- Multiple sclerosis: Multiple sclerosis is a chronic autoimmune disease that affects the central nervous system. This disease can damage the myelin sheath that surrounds the corticospinal tracts, leading to a positive March sign.
- Spinal cord injury: A spinal cord injury can damage the corticospinal tracts directly, leading to a positive March sign.
The March sign is an important diagnostic tool for neurologists and other healthcare providers. A positive March sign can help to confirm a diagnosis of damage to the corticospinal tracts. This information can then be used to guide treatment decisions.
Symptoms
The involuntary flexion of the toes when the foot is dorsiflexed is a classic sign of damage to the corticospinal tracts. This sign is known as the March sign. The March sign is a simple and easy-to-perform test that can help to diagnose damage to the corticospinal tracts.
The corticospinal tracts are a group of nerve fibers that connect the brain to the spinal cord. These tracts are responsible for controlling voluntary movement. Damage to the corticospinal tracts can cause a variety of symptoms, including weakness, spasticity, and difficulty with coordination.
The March sign is a valuable diagnostic tool because it can help to identify damage to the corticospinal tracts at an early stage. This information can then be used to guide treatment decisions. For example, a patient with a positive March sign may be referred to physical therapy to help improve their mobility. In some cases, surgery may be necessary to repair the damaged corticospinal tracts.
Understanding the connection between the March sign and damage to the corticospinal tracts is essential for healthcare providers who care for patients with neurological conditions. This understanding can help to ensure that patients receive the correct diagnosis and treatment.
Diagnosis
The diagnosis of a March sign is made through a physical examination. During the exam, the doctor will look for involuntary flexion of the toes when the foot is dorsiflexed. This sign is indicative of damage to the corticospinal tracts, which are responsible for controlling voluntary movement.
The physical examination is an important part of diagnosing a March sign because it allows the doctor to assess the neurological status of the patient. The doctor will also look for other signs of damage to the corticospinal tracts, such as weakness, spasticity, and difficulty with coordination.
Understanding the connection between the March sign and damage to the corticospinal tracts is essential for healthcare providers who care for patients with neurological conditions. This understanding can help to ensure that patients receive the correct diagnosis and treatment.
For example, a patient with a positive March sign may be referred to physical therapy to help improve their mobility. In some cases, surgery may be necessary to repair the damaged corticospinal tracts.
Prognosis
The March sign is a neurological sign that indicates damage to the corticospinal tracts. The corticospinal tracts are a group of nerve fibers that connect the brain to the spinal cord. These tracts are responsible for controlling voluntary movement. Damage to the corticospinal tracts can cause a variety of symptoms, including weakness, spasticity, and difficulty with coordination.
A positive March sign is a strong indicator of damage to the corticospinal tracts. This damage can be caused by a variety of conditions, including stroke, multiple sclerosis, and spinal cord injury. Patients with a positive March sign are more likely to have a poor prognosis than those with a negative March sign. This is because damage to the corticospinal tracts can lead to a variety of complications, including:
- Difficulty walking
- Difficulty with fine motor skills
- Spasticity
- Weakness
- Pain
- Numbness
- Tingling
The prognosis for patients with a positive March sign depends on the severity of the damage to the corticospinal tracts. Patients with mild damage may only experience minor symptoms, while patients with severe damage may be unable to walk or perform other basic tasks.
There is no cure for damage to the corticospinal tracts, but there are treatments that can help to improve symptoms. These treatments include:
- Physical therapy
- Occupational therapy
- Speech therapy
- Medication
- Surgery
The goal of treatment is to help patients with a positive March sign to live as independently as possible.
Understanding the connection between the March sign and a poor prognosis is essential for healthcare providers who care for patients with neurological conditions. This understanding can help to ensure that patients receive the correct diagnosis and treatment.
