Research Background and Problem

• Research Background:
  • Individuals with severe spinal cord injury (SCI) require long-term execution of various complex self-care behaviors, with pressure relief (PR) being particularly critical to prevent life-threatening pressure ulcers (PUs).
  • 85% of SCI patients develop PUs due to prolonged wheelchair use, leading to increased hospitalization rates and significantly reduced quality of life.
  • Despite the relative simplicity of PR operations, their high frequency (required 2-4 times per hour) and the inadequacy of current self-management interventions result in low adherence rates.
• Problems and Challenges:
  • Lack of dynamic and data-driven technological support to help SCI users comply with PR guidelines.
  • HCI research often overlooks SCI patients, especially those with complex comorbidities and high-frequency self-care needs.
  • Individual perceptions of PR timing and methods vary and are influenced by social and environmental factors, increasing the difficulty of adherence.
• Research Motivation:
  • To explore how technology can assist individuals with severe SCI in improving PR behaviors, understand their current PR habits, and empower personalized and dynamic support systems.

Solution

• Methods and Research Design:
  • A mixed-method approach combining semi-structured interviews and need validation storyboards (speed dating method) was used to study PR behaviors in SCI patients.
  • Nine design storyboard scenarios were employed to present hypothetical PR-related technological interventions and gather user feedback.
  • Seven individuals with severe SCI were recruited for interviews and study sessions conducted via video conferencing.
• Technologies and Strategies:
  • The storyboards were derived from literature and feedback from clinical experts, featuring technological scenarios targeting different interaction categories (e.g., mobile apps, wheelchair-integrated reminder mechanisms).
  • Special attention was given to social contexts, reminder modalities (vibration, visual cues, voice notifications, etc.), and the need for personalized adjustments.
• Innovations:
  • Systematically identified reasons for non-adherence to PR among individuals with severe SCI, focusing on user experience to design humane and dynamic technological interventions.
  • Introduced the core concepts of Self-Determination Theory (autonomy, relatedness, competence) into the design of SCI care technologies for the first time.

Research Findings

• Findings:
  • Barriers:
    • Motivation: While patients highly value PR due to prior painful experiences with PUs, their understanding of PR timing and methods is inconsistent.
    • Forgetfulness: Patients heavily rely on internal time perception and external visual cues but often act too late due to physical signals like pain.
    • Social Barriers: Performing PR in public is perceived as embarrassing (e.g., tilting the wheelchair draws attention), creating psychological burdens on social participation.
    • Situational/Spatial Barriers: PR requires ample space, making it inconvenient in vehicles or crowded environments.
  • Technological Needs:
    • Users prefer reminders only for incomplete, incorrect, or missed PR actions rather than reminders for every execution.
    • Reminder modalities should be private, non-intrusive, and adaptable to environmental contexts (e.g., indoor vs. outdoor settings).
  • Psychological Needs:
    • Emphasis on autonomy: Users want full control over system settings (e.g., reminder timing, frequency).
    • Promotion of relatedness: Enhancing a sense of recognition through family and social support.
    • Enhancement of competence: Users wish to track and showcase their PR performance (e.g., collaborative data sharing or friendly competition with peers).
• Experimental Evaluation and Comparative Results:
  • The study revealed that clinical guidelines or educational materials alone are insufficient to consistently improve PR behaviors; designs must reflect high frequency, autonomy, and social inclusivity.
• Limitations and Future Directions:
  • The small sample size (7 participants) limits the generalizability of the findings to all SCI patients.
  • Future research could explore similar methods for other high-frequency self-care behaviors (e.g., breathing exercises, bladder management).
  • Recommendations include expanding the participant pool to include diverse SCI groups (e.g., manual wheelchair users and individuals at different rehabilitation stages).

Conclusion

This study, from an HCI perspective, identifies the pain points of individuals with severe SCI in high-frequency self-care behaviors and provides key design principles for technological interventions. For instance, chairable interfaces and dynamic reminder systems can support personalized goal setting and tracking optimization, fostering autonomy and social participation. This research offers new pathways for future studies in assistive technology.
