Ice-water (cold stress) immersion testing.

Trauma-induced cold intolerance (cold sensitivity) is characterised by pain, stiffness, altered sensibility, or colour change associated with cold exposure (Campbell and Kay 1998), and is common after nerve injury or surgery (Irwin et al 1997). The Immersion in Cold water Evaluation (ICE) is a cold stress test administered through a standardised protocol where the hand is immersed in cold water and the examiner monitors the pain response and re-warming (Traynor and MacDermid 2008).
