ICD-10: G11.4

Hereditary spastic paraplegia (HSP), classified under ICD-10 code G11.4, is a group of inherited disorders characterized primarily by progressive weakness and stiffness of the legs due to degeneration of the upper motor neurons. This condition is part of a broader category of hereditary ataxias and is notable for its impact on mobility and quality of life.

Clinical Features

Symptoms

The hallmark symptoms of hereditary spastic paraplegia include:

• Spasticity: Increased muscle tone leading to stiffness and difficulty in movement.
• Weakness: Progressive weakness in the lower limbs, which can affect walking and balance.
• Gait Abnormalities: Patients often exhibit a scissor-like gait due to the tightness in the leg muscles.
• Sensory Changes: Some individuals may experience sensory disturbances, although this is less common.
