Lesions of the lateral cerebellum cause all of the following, except:
Show Hint
Resting tremor is a basal ganglia sign; cerebellum gives action or intention tremor.

- Incoordination
- Intention tremor
- Resting tremor
- Ataxia
Show Solution
The Correct Option is C
Solution and Explanation
Sort the four choices by where they come from. The cerebellar hemispheres time and smooth voluntary limb movement, so when they are injured the patient cannot coordinate movement properly. This shows up as incoordination, as an unsteady ataxic gait, and as an intention tremor that grows as the finger nears its target. Three of the options are therefore standard cerebellar findings. The odd one out is resting tremor, which describes a tremor seen while the limb is relaxed and supported. That pattern points to the basal ganglia and is the hallmark of Parkinsonism, not of cerebellar pathology. Cerebellar tremor behaves in the opposite way, being quiet at rest and emerging only with action. The exception asked for is the resting tremor.
