[Little known sequelae of sprains of the cervical spine].

After cervical sprain not only pain and neuropsychological disturbances may occur, but also the following sequelae: cervical dystonia, and torticollis, dizziness, hearing loss for low frequencies, dysphonia and globus. Except for dystonia the symptoms often respond to manipulation of a blocked articulation between occiput and atlas or axis and the third cervical vertebra.
