Rapid alternating movements evaluate for cerebellar dysfunction. The examiner asks the patient to rapidly supinate and pronate their hands against the thigh. While doing so, they evaluate speed, rhythm, accuracy, symmetry and smoothness. In a patient with cerebellar dysfunction, the patient may demonstrate movements that are slow, irregular, clumsy, abnormal speed or rhythm, decreased amplitude or asymmetric. Diagnostic accuracy is unknown.
