Area of Science:

  • Orthotics and Prosthetics
  • Rehabilitation Engineering
  • Human Factors Engineering

Background:

  • Lower extremity orthotic devices (LEODs) are crucial for mobility and function.
  • User perceptions of LEODs are vital for device effectiveness and adherence.
  • Existing LEODs may not adequately address the full spectrum of user needs.

Approach:

  • Systematic review of scientific (PubMed, Web of Science) and open sources (Google Search).
  • Inclusion of studies reporting user perceptions of LEODs across various diagnoses and device types.
  • Independent coding of 1616 user perceptions by trained coders.

Key Points:

  • Functional needs were most frequently perceived and positively received.
  • Expressive, aesthetic, and accessibility needs were more negatively perceived, especially in open sources.
  • User perceptions varied significantly based on diagnosis and specific LEOD type.

Conclusions:

  • LEODs have substantial room for improvement in meeting users' functional, expressive, aesthetic, and accessibility (FEA2) needs.
  • Addressing unmet FEA2 needs can improve user satisfaction and increase LEOD utilization.
  • Future LEOD design, prescription, and implementation should prioritize a holistic understanding of user needs.
