The dorsal (posterior) spinocerebellar tract carries unconscious position sense from the leg and lower trunk to the cerebellum on the same side. It begins in Clarke's column (nucleus dorsalis), which lies at T1-L2, and runs up the edge of the lateral cord to enter the cerebellum through the inferior cerebellar peduncle.

Supplies the cerebellum with detailed, moment-to-moment information on the position and movement of the leg on the same side.
Damage to the spinocerebellar tracts adds limb ataxia to cord lesions. In Friedreich ataxia, degeneration of Clarke's column and the spinocerebellar tracts, along with the dorsal columns and corticospinal tracts, causes progressive ataxia from childhood or adolescence.
An inherited disorder causing degeneration of the spinocerebellar tracts, dorsal columns and corticospinal tracts, with progressive ataxia, loss of reflexes and heart disease.
Poor coordination of the legs from damage to spinal proprioceptive pathways, including the spinocerebellar tracts.
