A Study on Digital Therapy Intervention Strategies for Sub-healthy Cervical Spine Conditions among College Students: An Exploration of Design Methodology from Macro Environment to Micro Interaction

Abstract

Abstract— There is growing concern regarding the poor health of the cervical spine in college-aged individuals and current interventions are failing to provide adequate levels of compliance, personalization, and adaptability to the various situations in which an intervention may be used. The purpose of this study is to identify the differences in the importance of digital therapeutics (DTx) functional requirements between 125 college student users and 5 rehabilitation professionals by utilizing the "Design Research Strategy Driven" (SDDR) methodology and employing Social-Economic-Technical (SET) analysis, Analytic Hierarchy Process (AHP), and t-test comparison of the data for revealing core tensions in need.Through the improved "Function-Behavior-Strategy" (FBS-S) model and expert workshops, an original "DTx Strategy Canvas" was constructed, comprising four major design principles, twelve core strategies, and thirty specific tactics. The results show that users place more emphasis on fun and motivation, while experts focus on clinical professionalism. The study verifies the effectiveness and innovativeness of the SDDR paradigm in guiding the design of DTx products for college students with suboptimal cervical spine health.
