Hereditary spastic paraplegia (HSP) is a hereditary degenerative disorder affecting the corticospinal tracts (long never fibers that supply the upper and lower limbs) within the spinal cord.

Family clinical history and physical and neurological examinations are the first tools in HSP diagnosis.

There is no curable or preventive treatment for HSP, except for antispasmodic drugs to reduce muscle spasms.

Good exercise activities for paraplegics are upper body strength training, if they like to play sports and are still active they can play basketball or tennis too.

Paraplegia - paralysos of the lower body.
