Explain the effect on locomotion/body movement when cerebellum is damaged or injured

Ataxia deficits include: Delay in the initiation of movement. Inaccuracy in range and direction (dysmetria) and decomposition of movement (moves shoulder first and elbow second). Tremor increases on approaching nose (action) The irregular pattern of alternating movements, such as when pronating and supinating the forearm while flexing and extending at the elbow as rapidly as possible.
