The Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI) reliably measures walking ability in individuals with spinal cord injury. This observational tool is valid and sensitive, whether used live or with video recordings.

Area of Science:

  • Rehabilitation Medicine
  • Neurology
  • Biomedical Engineering

Background:

  • Gait assessment is crucial for individuals with spinal cord injury (SCI).
  • Existing observational tools may lack comprehensive validation for SCI populations.
  • Developing reliable and valid instruments is essential for tracking functional recovery.

Purpose of the Study:

  • To develop and validate the Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI).
  • To assess the reliability, validity, and sensitivity of the SCI-FAI for measuring gait in SCI.
  • To determine if live or videotaped assessments yield comparable results.

Main Methods:

  • The SCI-FAI was developed and tested on 22 subjects with incomplete SCI.
  • Four raters scored subjects live and from videotapes across multiple sessions.

  • Inter-rater and intra-rater reliability were calculated using Intraclass Correlation Coefficients (ICC).
  • Validity was assessed by correlating SCI-FAI scores with walking time.
  • Sensitivity was evaluated by comparing gait score changes with lower extremity strength changes in 19 SCI subjects before and after a walking program.

    • Main Results:

    • A moderate-good negative correlation was found between SCI-FAI gait scores and walking time (r = -0.742 to -0.700).
    • Inter-rater reliability was moderate-good (ICC = 0.703–0.840), and intra-rater reliability was good (ICC = 0.850–0.960).
    • A moderate correlation was observed between changes in SCI-FAI scores and changes in lower extremity strength (r = 0.58).

    Conclusions:

    • The SCI-FAI is a reliable, valid, and sensitive instrument for assessing walking ability in individuals with SCI.
    • Gait analysis using the SCI-FAI demonstrates comparable reliability whether performed live or from videotaped records.
    • The SCI-FAI can be a valuable tool in SCI rehabilitation for monitoring functional ambulation.
