AbstractAbstract PDF
There are debates about whether peripherally induced movement disorders exist. We report a case of upper limb tremor induced by peripheral nerve injury. A 25-year-old male patient presented with pain and tremor of the left upper extremity, 2 days after a car accident. Magnetic resonance images of the brain and cervical spine were normal. His past medical history was unremarkable and there were no family members with symptoms of movement disorders. He suffered from an aggravating tremor for about 10 minutes, four to six times a day. We treated the patient with medication, epidural infusion, cervical nerve root block and trigger point injection of the trapezius muscle. The pain subsided 50% and the incidence of tremor attacks was reduced to once or twice a day. The role of peripheral trauma in the genesis of movement disorders has not been generally accepted. It is unclear whether peripheral trauma can induce dystonia and other movement disorders. It has been proposed that peripheral trauma can alter sensory input and induce cortical and subcortical reorganization that generates a movement disorder. Some studies provide evidence for central reorganization following peripheral injury.
