Study Details

Brief summary:

The purpose of the current study is to identify the optimal method of collection of pain intensity data. The study will compare three collection methods: a hand-written pain journal, a smartphone app, and a novel electronic pain recorder device. Patients will be randomly assigned to one of three methods and instructed to record their pain level as often as they like. The number of pain intensity recordings per day will then be compared across groups.
