Nerve machine
From Tardis Wiki, the free Doctor Who reference
The nerve machine was a device which used by the Daleks to remotely paralyse the First Doctor whilst he was within the TARDIS. After determining the Doctor's affliction using the telepathic helmet, Ian Chesterton left the TARDIS and found the nerve machine. By upsetting the mechanism, Ian ruined the nerve machine and thus set the Doctor free. (COMIC: Dr. Who and the Nerve Machine)
