Managing cold intolerance after hand injury: A systematic review.

Objectives: This systematic review seeks to understand whether cold intolerance (CI) improves with time and if there is any role for management strategies such as behavioural therapy, surgery, or pharmacotherapy.

Methods: Two independent reviewers used a predefined search strategy to query MEDLINE, PubMed, Embase, CINAHL, Cochrane Library, Web of Science and Google Scholar databases. Articles written in English, Studies of interventions (such as pharmacotherapy or behavioural therapy) for cold intolerance in adult patients with a history of hand injury along with prevalence over time were included for review.
