Answer
The dorsal and ventral ascending spinocerebellar tracts are concerned with sending proprioceptice signals form trunk and lower limbs to the cerebellum. The cerebellum integrates these signals and sends back messages to relevant muscle groups that enable us subconsciously to maintain balance and posture when we are standing or moving.
A cut of the dorsal spinocerebellar would impair balance and posture and contribute to falls . But the dorsal spinocerebellar decussates, so he nature and severity of the balance deficit would depend on the relation of the location of the severance of the tract relative to the position of the tract decussation
The ventral spinocerebellar tract is a "double-crosser". It decussates but the crosses back. This should thus be treated as a tract that does not cross, if the tract severance is rostral or superior to the cross-back.
Work Step by Step
The ventral spinocerebellar is responsible for subconscious maintenance of balance and posture. This tract is very interesting because it decussates twice. The effect of cutting the tract would, of course, depend on where it was cut, on what limb, after which cross --first or second. In any case, damage to this tract would impair subconscious maintenance of balance, posture and movement. It would conduce to frequent falls.
