We present seven cases of tremor caused by mild head injury without loss of consciousness. The interval between head trauma to onset of symptoms was 1 to 4 weeks. A posture and kinetic tremor of the hands and head occurred unassociated with other neurologic signs. Myoclonic-like jerking was frequently present. Neuroimaging studies were normal. Clonazepam administration resulted in tremor reduction in three patients and propranolol decreased tremor in one patient. A tremor, similar to essential tremor, can be a rare complication of head trauma.
我们报告了7例由轻度头部损伤引起的震颤病例，这些患者均未失去意识。头部外伤至症状出现的间隔时间为1至4周。手部和头部出现姿势性和运动性震颤，且与其他神经体征无关。常出现类似肌阵挛的抽搐。神经影像学检查结果正常。3例患者使用氯硝西泮后震颤减轻，1例患者使用普萘洛尔后震颤减轻。与特发性震颤相似的震颤可能是头部外伤的一种罕见并发症。
