Understanding Observational Gait Analysis

Apr 22, 2025

Lecture on Observational Gait Analysis

Introduction

  • Presenters: Tracy and Will
  • Lecture series focus: Observational gait analysis
    • Discussing the why and how
    • Advantages and disadvantages
  • Future topics: Systematic approach to performing gait analysis
  • Required material: JAKC observational gait analysis form
    • Available on website and YouTube description

Definition and Importance

  • Observational gait analysis
    • Observing a patient's gait to identify deviations from normal patterns
    • Essential to understand what a normal gait looks like
    • Aids in identifying impairments or functional deficits

Applications

  • Wide range: video, photos, apps, and direct observation
  • Focus of the lecture: Clinician's direct observation

Pros of Observational Gait Analysis

  • Easy to perform anywhere
  • No special equipment needed
  • Can be done in small spaces

Cons of Observational Gait Analysis

  • Qualitative measure: lacks a quantitative score
  • Research evidence is poor
  • Transitory: No permanent record unless documented immediately
  • Reliability and Validity concerns
    • Reliability: Consistency of a test
      • Inter-rater reliability: Agreement between different observers
      • Intra-rater reliability: Consistency of the same observer
    • Validity: Ability to measure what it is supposed to measure

Combining Observational Gait Analysis with Other Assessments

  • Completes the clinical picture with:
    • Subjective history
    • Objective measures (range of motion, strength, etc.)
    • Outcome measures (e.g., Berg balance score)
  • Provides functional insight into patient conditions

Upcoming Topics: Gait Analysis Forms

  • Research uses forms despite poor reliability and validity
  • Useful for learning and systematic analysis
  • Organize information by anatomical area and gait phase

Gait Analysis Tips

  1. Prepare the Patient

    • Ensure visibility of joints
    • Remove heavy clothing or baggy pants
    • Consider removing assistive devices safely
  2. Global Assessment

    • Initial overview of patient's gait
    • Observe speed, stability, step length, support
  3. Specific Assessment

    • Systematic approach: toe-to-head evaluation
    • Use multiple angles (lateral and anterior-posterior)
  4. Select Reference Limb

    • Focus on the problematic side
    • Perform separate analysis for bilateral issues
  5. Review and Plan

    • Familiarize with the form before starting
    • Plan the approach (top-down, bottom-up)
  6. Mark the Form

    • Use the checklist format
    • Document any additional observations

Conclusion

  • Next lecture: Deep dive into the JAKC observational gait analysis form
  • Objective: Provide focus and guidance using a simple format
  • Reminder to take a break before the next session
