Observation. Carefully observe the patient to detect any twitches, tremors, or other involuntary movements, as well as any unusual paucity of movement (see KCC 15.2 and KCC 16.1 in Neuroanatomy through Clinical Cases 3e). Note also the patient’s posture.
What Is Being Tested?
Involuntary movements and tremors are commonly associated with lesions of the basal ganglia or cerebellum (see KCC 15.2 and KCC 16.1 in Neuroanatomy through Clinical Cases 3e) and with toxic or metabolic disorders. Tremors can also occasionally be seen with peripheral nerve lesions.
