An adjustable leadwire device for connecting at least one surface electrode to a physiological monitor includes a length of insulated wire between a first attachment end and a second attachment end. The first attachment end includes a first connection means configured to conductively connect to the surface electrode and the second attachment end includes a second connection means configured to conductively connect to the physiological monitor. At least a portion of the length of insulated wire is coiled to form a helix. A sheath surrounds the helix and has a first end opening and a second opening. The sheath is configured such that coiled insulated wire is extendable out of at least one of the first end opening or the second end opening by pulling a respective one of the first attachment and the second attachment end in order to adjust a length of the adjustable leadwire device.
