Common Causes

• Trauma: Most commonly, incomplete lesions result from traumatic events such as falls, motor vehicle accidents, or sports injuries.
• Diseases: Conditions like multiple sclerosis, transverse myelitis, or infections can also lead to incomplete spinal cord lesions.

Signs and Symptoms

Motor Function

• Weakness: Patients may experience varying degrees of weakness in the lower limbs, which can affect mobility and balance.
• Spasticity: Increased muscle tone or spasticity may be present, leading to stiffness and involuntary muscle contractions.

Sensory Function

• Altered Sensation: Patients often report changes in sensation, such as numbness, tingling, or a burning sensation in the legs or feet.
• Pain: Neuropathic pain may occur, which can be challenging to manage and may require specific pain management strategies.

Reflexes

• Hyperreflexia: Exaggerated reflexes may be observed, indicating an upper motor neuron lesion.
• Babinski Sign: The presence of a positive Babinski sign can indicate neurological impairment.

Autonomic Function

• Bladder and Bowel Dysfunction: Patients may experience difficulties with bladder control, leading to urinary retention or incontinence, as well as bowel dysfunction.
• Sexual Dysfunction: Changes in sexual function are common and can significantly impact quality of life.

Patient Characteristics

Demographics
