Study Summary
One of the primary goals of spine surgery is to reduce pain and increase mobility to improve patients' quality of life. Currently, there is no established method for surgeons to objectively track their patients' mobilization postoperatively. This study is the first prospective trial utilizing the Apple Watch to objectively track patients before and after elective spine surgery. The investigators hypothesize that the ability of patients to track their own activity and discuss with their surgeon objective mobilization goals will not only help patients achieve empowerment in their own care but also improve their overall satisfaction and self-reported outcomes after spine surgery.
Primary Outcome
Steps and distance (meters) collected by Apple Watch were averaged across the outcome measure time frame. Survey scores were collected at the end of the outcome measure time frame. * Short Form-36 (SF-36): Scores range from 0 to 100. Higher scores indicate better health outcomes. * EuroQOL-5 Dimensional Questionnaire (EQ-5D): Scores range from 0 to 100. Higher scores indicate better health outcomes. * Patient-Reported Outcomes Measurement Information System (PROMIS): Scores range from 41 to 78.
