Simple Explanation

This study focuses on the development and testing of a mobile app called CMAP, designed to help Veterans with spinal cord injuries prevent pressure injuries. The app uses a pressure mat in the wheelchair that sends real-time pressure information to a smartphone, providing feedback to the user. The research involved multiple stages, including gathering feedback from Veterans to improve the app's design and testing its feasibility and usability in their homes.

Study Duration
Three-year
Participants
18 Veterans with spinal cord injury
Evidence Level
Not specified

Key Findings

  • 1
    Veterans found the CMAP system helpful for skin ulcer prevention and monitoring.
  • 2
    The live pressure map feature and reminders to shift weight were highly valued.
  • 3
    Inconsistent functionality, due to the many interconnected components, was the main barrier to system use.

Research Summary

This study reports on the iterative redesign, feasibility, and usability of the Comprehensive Mobile Assessment of Pressure (CMAP) system’s mobile app used by Veterans with SCI. The multi-staged, mixed methods approach proved to be successful and informative for the app development. Overall both the power and manual wheelchair users reported that they wanted to use the system, felt confident using the system, and that the functions of the system were well integrated.

Practical Implications

Real-time Biofeedback Tool

The CMAP system offers real-time visual feedback to compensate for reduced sensation, potentially preventing pressure injuries.

Remote Monitoring of Seating Needs

The system facilitates potential remote monitoring of seating needs, limiting unnecessary medical visits.

Tailored System Development

Future development should focus on understanding specific user needs, addressing hardware challenges based on user feedback, and testing with diverse populations.

Study Limitations

  • 1
    Small sample size.
  • 2
    The older users do not represent all Veterans with SCI.
  • 3
    Lack of comparison technology in this study design.
