Lorraine is House's physiotherapist in the Season 3 episode Whac-A-Mole. She was portrayed by actress Deborah Lacey.

Guilty over Wilson's troubles with Tritter, House's shoulder starts acting up and he goes to Lorraine for physiotherapy. She reminds him not only that he's using the cane in his wrong hand, but that he should be using a therapeutic cane instead of a decorative one. She confiscates his cane and gives him a standard hospital issued cane.
