Trial Outcomes & Findings for Improving Spine Surgical Care With Real-Time Objective Patient Tracking Using the Apple Watch (NCT NCT04379921)

NCT ID: NCT04379921

Last Updated: 2025-12-19

Results Overview

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 78.3. Higher scores indicate worse health outcomes. * Neck Disability Index (NDI): Scores range from 0 to 100. Higher scores indicate worse health outcomes. * Oswestry Disability Index (ODI): Scores range from 0 to 100. Higher scores indicate worse health outcomes.

PRIMARY outcome

Timeframe: 2-6 weeks pre-operatively

Population: Participants with data for the respective time frame and patient-reported outcome. This outcome was evaluated on the Apple Watch and App group only (the Control group was not assigned an Apple Watch).

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.

Timeframe: 2-6 weeks pre-operatively; 4-6 weeks, 6 weeks-3 months, 3-6 months, and 6-12 months post-operatively

Population: Participants with available data at the respective time point. This outcome was evaluated on the Apple Watch and App group only (the Control group was not assigned an Apple Watch).

Steps per day collected by Apple Watch were averaged across the respective outcome measure time frame. Change was calculated as the post-baseline value minus the baseline value (which was normalized to zero).
