Abstract: Electrical probe assemblies, such as nerve probe assemblies, are disclosed herein. In one example implementation, a nerve probe assembly may include an electrical probe including an electrode disposed on or about an end thereof for electrically stimulating tissue or recording stimulated tissue activity, an axial length of the electrical probe including a shapeable part; a rigid sheathing adapted to cover and thereby inhibit a portion of the shapeable part of the axial length of the electrical probe from being shaped, the portion of the shapeable part covered by the rigid sheathing being adjustable; and a handle and an adjustment structure affixed to respective ones of the electrical probe and the rigid sheathing, the handle and the adjustment structure adapted to cooperate to enable adjustment of the portion of the shapeable part of the axial length of the electrical probe covered by the rigid sheathing.
